Property Search in St. Louis County begins with the Assessor’s online portal, where a user can enter a street address, parcel identification number, or owner name to retrieve official public records. The system returns the current property owner, legal description, assessed value, tax status, and land dimensions that the assessor has recorded after the most recent sale or assessment update. By selecting the “search by address” field, the database matches the input to the exact parcel and displays the property’s tax map, zoning classification, and improvement details such as year built and square footage. A “search by parcel number” query isolates the record without ambiguity, presenting the parcel’s block, lot, and subdivision identifiers alongside historic ownership changes. Users who prefer “search by owner name” can view all parcels linked to that name, revealing ownership history and any recorded deeds. The portal also supports “search by legal description” for those with deed language rather than a street address, enabling a precise match to the assessor’s records.
Property Search online for St. Louis County also includes a GIS map that overlays parcel boundaries on satellite imagery, allowing a visual property map investigation alongside the textual record. Clicking a parcel displays its identification number, land area, and classification such as residential, commercial, or agricultural, then links to the full property record card with tax exemption details and assessment history. The platform supports property search by location through a zip code or municipality filter, making it easy to compile a property database of every lot within a chosen district. To answer questions like how to find a property’s assessed value or how to search for a property by address, the site lists assessed and taxable values with the recent tax year, showing payment status. Researchers seeking how to find a property owner by address can use the property lookup by address feature, which reveals the current owner name and mailing address recorded for tax purposes. The same interface enables parcel search by parcel number, land records search by legal description, and a property assessment search that returns market, appraised, and land values for any parcel.
How to Search Property Records
Property records search in St. Louis County is handled through the Assessor’s online portal, which gives you direct access to land records, ownership data, and assessment details for every parcel in the county. Residents can also access official business records to verify current details. You can start a property records lookup using a street address, parcel identification number, account number, or owner name depending on the information you have available. The system draws from the same database used for official county assessment and tax billing, so the records you see reflect the most recently filed data. Whether you need to search property records by address for a home purchase or verify ownership history for a title review, the portal supports a structured query format that returns complete results.

Search Methods
- Visit the St. Louis County Assessor official search portal using the link above.
- Choose your preferred search method: address, owner name, parcel number, account number, legal description, property type, or map-based lookup.
- Enter the requested information in the search field, making sure spelling and numeric characters are accurate.
- Review the matching parcels displayed on the results page and select the specific record you need.
- Open the full property record card to view ownership, valuation, tax status, and map details.
Search by Property Address
Searching property records by address is the most common method for a property lookup by address, especially when you have a complete street name and number. You type the address into the portal and the database matches it to the official situs address recorded by the Assessor. The result shows the parcel tied to that address along with its classification, year built, and assessed value. A property search by address also reveals whether the property is residential, commercial, agricultural, or vacant land.
Search by Owner Name
A property search by owner name lets you locate every parcel associated with a specific individual, trust, or business entity. You can enter the last name first or the full name depending on the portal layout. This search records by owner method is useful when you need a complete property ownership records review for an estate, a divorce settlement, or a real estate transaction. The system returns all parcels linked to that name, including historical ownership if the previous owner field is populated.
Search by Parcel Number
Property search by parcel number returns the exact record without ambiguity because the parcel ID is unique to each lot. You enter the locator number, which is a combination of the township code, block, and parcel identifier. Searching property records by parcel number is the preferred method for surveyors, title companies, and appraisers who need precise parcel identification. The result presents the legal description, land area, and any recorded deed references tied to that parcel.
Search by Account Number
Property search by account number uses the unique billing reference assigned by the Collector of Revenue for tax purposes. This method is helpful when you have a tax bill or payment receipt but not the address. Searching property records by account number connects you to the same parcel data you would see through an address lookup, including the tax map, classification, and current tax status. It is commonly used by mortgage companies and title search services.
Search by Legal Description
Property search by legal description is used when you have metes and bounds language, a lot and block reference, or a subdivision name and unit number from a deed. You enter the legal description exactly as recorded in the deed document to retrieve the matching parcel. Searching property records by legal description is essential for vacant land, inherited parcels, or subdivisions where street addresses may not yet be assigned. The portal matches the description to the official record and returns the parcel ID, owner, and land details.
Search by Property Type
Property search by property type lets you filter records by category such as residential, commercial, agricultural, industrial, vacant land, or multifamily. This method is useful when you want to build a property database of a specific class within a given area. You select the property type from a dropdown menu and combine it with a location filter to narrow the results. It is frequently used by investors, brokers, and researchers analyzing a real property search across one segment.
Search by Location or Map
Property search by location uses a municipality filter, zip code, or interactive GIS map to display every parcel within a defined area. The GIS-based property search overlays parcel boundaries on aerial imagery so you can visually select a lot. Clicking a parcel on the map opens the same record card you would see through a text-based property lookup. This method is the fastest way to compile a list of all parcels in a neighborhood, school district, or commercial corridor.
Property Search Results
Once you complete a property records search, the portal returns a summary panel that displays the key identifiers tied to the parcel. The property search results page is designed to give you the owner name, address, parcel number, and classification at a glance before you open the full record card. You can compare multiple parcels side by side when running a property information search across several addresses. The results screen also shows whether the parcel has a recorded deed, an active tax exemption, or a recent assessment update.
Property Address
The property address shown in the results panel reflects the situs address recorded by the Assessor, which is the location where the property is physically located. This may differ from the mailing address used for tax bills if the owner resides elsewhere. Each property address is matched to a unique parcel record, which prevents duplicate entries when two parcels share part of a street frontage.
Owner Name
The owner name displayed in the results panel reflects the current recorded owner as of the most recent deed transfer. You can click on the owner name to view a full property search by owner name listing, which shows every parcel tied to that individual or entity. The owner name search results also include the owner mailing address and any co-owners recorded on the deed.
Parcel or Account Number
The parcel number and account number are both shown in the results panel to support different search preferences. The parcel number links to the official property identification, while the account number links to the tax billing record. You can use either identifier to revisit the same parcel without re-running a property search.
Property Type
The property type classification appears next to the parcel identifier so you can quickly identify whether the parcel is residential, commercial, agricultural, industrial, vacant land, or multifamily. This field reflects the Assessor’s classification, which is used to determine the assessment ratio applied to the property’s market value. The classification also drives the eligibility rules for certain property tax exemptions and credits.
Legal Description
The legal description is shown in abbreviated form in the results panel and in full detail on the property record card. It identifies the parcel using lot, block, subdivision, and metes and bounds references. Searching property records by legal description returns this field automatically, which makes it a primary search tool when no street address is available.
Property Location
The property location field displays the municipality, zip code, school district, and taxing jurisdiction for the parcel. This is useful for confirming which local services apply to the property and which tax rates will be applied during billing. The location field also links to the GIS map view for a visual confirmation of the parcel boundaries.
Assessment Information
The assessment information section displays the market value, assessed value, and taxable value for the parcel for the current tax year. These figures reflect the Assessor’s most recent valuation cycle and are updated annually based on sales activity and physical changes to the property. The assessment summary also notes the year of the last reassessment.
Tax Information
The tax information section displays the current tax year, the tax amount due, the payment status, and any delinquent balance owed on the parcel. This data is sourced from the Collector of Revenue’s billing system and is refreshed after each payment cycle. You can use this view to confirm whether a property has an outstanding tax lien before completing a real estate transaction.
Property Details
The property details page opens after you select a parcel from the property search results, presenting a complete profile of the lot and any improvements on it. The page is organized into identification, address, classification, land, and building sections to give you a full picture of the parcel. Property details lookup is helpful for buyers, sellers, appraisers, and researchers who need a complete record before making a decision. The data shown reflects the Assessor’s official file, which is updated after each deed transfer, building permit, or reassessment cycle.
Property Identification
Property identification begins with the parcel number, account number, and any state-assigned reference code for the lot. These identifiers are unique to the parcel and remain stable even when the owner changes. Property identification numbers are used across county departments to link the Assessor file, the Collector of Revenue billing file, and the Recorder of Deeds document index.
Property Address and Situs
The property address and situs address are the physical location of the parcel, while the tax billing address is the mailing address for the current owner. You may see a difference between the situs address and the mailing address if the owner lives elsewhere or uses a property management company. The situs address is the official address used by the Assessor for property identification and mapping purposes.
Parcel Information
Parcel information includes the lot size, acreage, dimensions, and parcel boundaries as recorded in the county GIS system. You can compare the recorded acreage against the legal description or a recent survey to confirm accuracy. Parcel information lookup is a common step in real estate due diligence because boundary discrepancies can affect valuation and tax calculations.
Legal Description
The legal description is the formal text used in deeds to identify the parcel, usually expressed as a lot and block number within a subdivision or as metes and bounds for unplatted land. This description must match the Assessor’s record exactly for a deed to be recorded without challenge. The legal description also determines how the parcel is referenced in the county land records index.
Property Classification
Property classification identifies the parcel as residential, commercial, agricultural, industrial, vacant land, or multifamily based on its use. Classification affects the assessment ratio, the tax rate, and the exemptions that may apply. A property classification change request can be filed with the Assessor if the use of the property has changed since the last classification review.
Lot and Land Information
Lot and land information includes the lot size in square feet or acres, the frontage, the depth, the topography, and any recorded easements. This section helps you evaluate the usable land area for development, landscaping, or setback compliance. Land information is also used to calculate the land value portion of the parcel’s total assessed value.
Building and Improvement Details
Building and improvement details list the year built, total square footage, number of stories, construction type, number of rooms, and any additions or outbuildings on the parcel. This information is gathered during the Assessor’s physical inspection or through building permit data. Improvement details are used to calculate the improvement value portion of the parcel’s assessed value.
Property Ownership Information
Property ownership information shows the current owner, the ownership history, and any recorded deed transfers tied to the parcel. This data is sourced from the Recorder of Deeds and linked to the Assessor’s parcel file. Property ownership lookup is commonly used during title searches, estate settlements, and real estate transactions to confirm who holds legal title. You can also review ownership changes over time to understand how long the current owner has held the property and at what price it last transferred.
Current Property Owner
The current property owner field reflects the most recent deed recorded with the Recorder of Deeds. The name displayed may be an individual, a trust, a limited liability company, or another legal entity. The owner mailing address used for tax billing is shown alongside the owner name so you can confirm the contact information on file.
Ownership History
Ownership history shows a chronological list of previous owners, the date of each transfer, and the deed reference number for each transaction. Property ownership history lookup is helpful when researching a chain of title or verifying the length of ownership for tax exemption eligibility. The history is sourced from recorded deed documents and is updated after each transfer is processed.
Property Transfer Information
Property transfer information includes the sale price, transfer date, deed type, and recording instrument number for each transaction. Property transfer records search is a critical step for buyers, lenders, and appraisers who need to confirm the most recent arms-length sale. The transfer data is linked to the Recorder of Deeds document index for verification.
Deed Reference
The deed reference field displays the Recorder of Deeds instrument number, book, and page for the most recent deed. This reference allows you to retrieve the full recorded deed document from the Recorder’s office if you need to review the legal language. The deed reference is also used to verify ownership claims in title searches.
Ownership Changes
Ownership changes are logged automatically each time a new deed is recorded and processed by the Assessor. A property ownership change may trigger a reassessment if the transfer meets the requirements of state law. The portal will display a flag on the property record card when a recent ownership change is being processed.
Multiple Owners and Ownership Interests
When a parcel is owned by more than one party, the portal lists each owner and the recorded ownership interest, such as joint tenancy, tenancy in common, or survivorship rights. Multiple owners can be searched individually to view parcels tied to each name. Ownership interest data is important for estate planning, divorce proceedings, and partition actions.
Property Valuation and Assessment
Property valuation and assessment data reflect the Assessor’s estimate of the parcel’s market value, appraised value, and assessed value for the current tax year. The property valuation section breaks down the total value into land value and improvement value, and includes a history of past assessments. Property assessment search is used by owners who want to review their valuation, by buyers who want to verify a list price, and by tax appeal attorneys preparing a protest. The valuation figures are updated after each reassessment cycle, which in Missouri occurs on a two-year cycle for residential property and annually for commercial property.
Market Value
Market value is the Assessor’s estimate of the most probable price the property would sell for in an open market transaction. The figure is based on comparable sales, income data, or cost data depending on the property type. Residents can also access official county auditor to verify current details. Market value is the foundation for the assessed value calculation and the property tax bill.
Assessed Value
Assessed value is the value used to calculate the property tax bill after the assessment ratio is applied. For residential property in Missouri, the assessed value is typically 19 percent of the market value. How to find a property’s assessed value is one of the most common searches on the Assessor portal because the figure directly affects the tax bill.
Appraised Value
Appraised value is the valuation placed on the property by the Assessor during the most recent physical inspection or mass appraisal cycle. It may equal the market value or may be adjusted based on property condition, functional obsolescence, or external factors. The appraised value is shown alongside the assessed value for comparison purposes.
Land Value
Land value is the portion of the total value attributed to the lot itself, exclusive of any buildings or improvements. The figure is based on comparable land sales, location factors, and zoning considerations. Land value is important because it is one component of the total assessed value and can be challenged separately during an appeal.
Improvement Value
Improvement value is the portion of the total value attributed to buildings, structures, and other permanent improvements on the parcel. The figure is calculated using the cost approach, which considers replacement cost, depreciation, and market adjustments. Improvement value changes when additions are made, when buildings are demolished, or when the condition of the structure changes.
Assessment History
Assessment history shows the parcel’s market value, assessed value, and classification for each past assessment cycle. You can review this history to see how the valuation has changed over time and to identify any patterns that may support an appeal. The history is also useful for tracking the impact of past improvements or zoning changes on the parcel’s value.
Property Value Changes
Property value changes reflect any adjustments made to the valuation during the current cycle, such as a correction, an appeal decision, or a reclassification. The portal flags any parcel where a value change has occurred since the prior cycle. Reviewing property value changes is a useful step before paying the tax bill or filing an appeal.
| Valuation Type | Description | Used For |
|---|---|---|
| Market Value | Estimated sale price in an open market | Foundation for valuation calculations |
| Assessed Value | Value after assessment ratio is applied | Property tax calculation |
| Appraised Value | Value from appraisal or mass appraisal model | Reference and comparison |
| Land Value | Value of the lot only | Appeal and valuation breakdown |
| Improvement Value | Value of buildings and structures | Appeal and valuation breakdown |
Property Tax Information
Property tax information shows the current tax year billing details, payment status, exemptions, and any delinquent balance for the parcel. The data is sourced from the Collector of Revenue billing system and is updated after each tax payment cycle. Property tax information search is useful for homeowners verifying their bill, for buyers reviewing the cost of ownership, and for lenders confirming tax escrow balances. The portal also displays the tax rate and the taxing jurisdictions that apply to the parcel.
Property Tax Records
Property tax records show the tax amount billed, the amount paid, and the balance owed for each tax year on record. How to find property tax information by address is a common request that is answered by the Assessor portal linking directly to the Collector of Revenue billing system. The records display the full payment history of the parcel for the past several years.
Taxable Value
Taxable value is the assessed value after any exemptions or tax credits have been applied. This figure is multiplied by the local tax rate to calculate the annual tax bill. The taxable value may be lower than the assessed value if the owner has qualified for a homestead exemption, a senior citizen credit, or a disability exemption.
Tax Amounts
Tax amounts are displayed for each taxing jurisdiction that applies to the parcel, including the county, the municipality, the school district, the fire district, and any special districts. The total tax bill is the sum of all jurisdiction-level amounts. The portal breaks down the bill so you can see exactly where each portion of the tax payment is directed.
Tax Year
The tax year field displays the current billing year for the parcel. In Missouri, property taxes are billed in arrears, meaning the tax bill issued in year X covers the ownership period for that same year. The tax year field is updated annually after the assessment cycle is complete.
Tax Payment Status
Tax payment status shows whether the current tax bill has been paid in full, paid in part, or remains outstanding. The status is refreshed after each payment cycle by the Collector of Revenue. A parcel with an unpaid balance will display a flag on the property record card as a warning to potential buyers and lenders.
Delinquent Property Taxes
Delinquent property taxes are taxes that were billed in a prior year and remain unpaid. The portal lists the delinquent amount, the year of delinquency, and any penalties or interest that have accrued. Delinquent taxes may result in a tax lien against the property and eventual tax sale if not resolved.
Tax Exemptions and Adjustments
Tax exemptions and adjustments reduce the taxable value of the parcel based on the owner’s qualifications or the property’s use. Common exemptions include homestead exemption, senior citizen property tax credit, disability exemption, and exemptions for charitable or religious use. The portal lists each exemption applied to the parcel and the dollar amount of the reduction.
| Tax Field | Description |
|---|---|
| Taxable Value | Assessed value minus exemptions |
| Tax Amount | Total tax billed for the current year |
| Payment Status | Paid, partial, or unpaid balance |
| Delinquent Amount | Past-due taxes plus penalties and interest |
| Exemptions | Credits reducing the taxable value |
Property Search by Property Type
Property search by property type allows you to filter the Assessor’s database by use category so you can build a targeted list of parcels within a specific segment. The classification is assigned by the Assessor based on the primary use of the land and any improvements on it. You can combine the property type filter with a location filter, an owner filter, or a value range to narrow the results. This search method is commonly used by investors, brokers, appraisers, and researchers analyzing a specific segment of the real estate market in St. Louis County.
Residential Properties
Residential properties include single-family homes, condominiums, townhouses, and two-family dwellings used primarily for residential occupancy. The residential classification carries an assessment ratio of 19 percent in Missouri. Residential property search returns ownership, valuation, and building details for each home in the database.
Commercial Properties
Commercial properties include office buildings, retail centers, hotels, restaurants, and other structures used for business purposes. Commercial parcels are assessed annually at 32 percent of market value. Commercial property search is used by investors analyzing income-producing assets and by appraisers building comparable sales data.
Agricultural Properties
Agricultural properties include farmland used for crop production, livestock grazing, or other agricultural operations. Parcels in this classification may qualify for an agricultural productivity valuation based on the land’s productive capacity. Agricultural property search helps confirm the current use of the land and the eligibility for any special valuation program.
Vacant Land
Vacant land parcels are unimproved lots that have no buildings or permanent structures. Vacant land search is used by developers looking for buildable lots and by neighbors confirming ownership of adjacent parcels. The valuation of vacant land is based on comparable land sales and location factors.
Industrial Properties
Industrial properties include manufacturing facilities, warehouses, distribution centers, and other structures used for industrial operations. Industrial parcels are assessed annually at 32 percent of market value. Industrial property search returns parcel size, building details, and ownership data for these specialized assets.
Multifamily Properties
Multifamily properties include apartment buildings, duplexes, and other residential structures with three or more units. These parcels are typically classified as residential but may carry a commercial assessment ratio if used as income-producing rental property. Multifamily property search supports investor analysis and rental market research.
Property Maps and Location Data
Property maps and location data provide a visual representation of parcels, boundaries, and geographic features across St. Louis County. The GIS-based property search overlays parcel lines on aerial imagery so you can identify properties by location rather than by text query. Property map data is maintained jointly by the Assessor and the county’s Geographic Information Systems department. You can use the map to confirm parcel boundaries, view neighboring parcels, and link directly to the parcel record card.
Property Location Map
The property location map shows the geographic position of the parcel within the county, including its municipality, zip code, and school district. You can pan and zoom the map to view the surrounding area and nearby streets. The map is the primary tool for a GIS property search when you do not have a specific address or parcel number.
Parcel Boundaries
Parcel boundaries are drawn on the map to show the exact dimensions of each lot. The boundaries reflect the recorded legal description and any recorded plats or surveys. Parcel boundary data is updated after each deed transfer, subdivision, or boundary line adjustment is recorded.
Neighboring Parcels
The map shows every neighboring parcel, with a link to each one’s record card for quick navigation. You can click on any adjacent parcel to view its owner, classification, and assessed value. This feature is useful for research on property lines, shared driveways, or neighboring land use.
Street and Address Information
Street and address information appears as labels on the map, showing the official street names and address ranges used by the county addressing system. The labels are linked to the parcel database so clicking an address opens the matching record. This feature helps you confirm the situs address tied to a specific parcel.
GIS Property Data
GIS property data includes the parcel polygon, the centroid coordinates, the acreage, and any overlay districts such as flood zones, historic districts, or zoning layers. The data can be exported for use in external mapping software. GIS property search is used by surveyors, planners, and researchers who need spatial data for analysis.
Map-Based Property Search
Map-based property search allows you to draw a shape on the map, select a neighborhood, or filter by school district to retrieve all parcels within a defined area. The results are displayed as a list and as highlighted polygons on the map. This method is the fastest way to compile a property database of every parcel within a specific boundary.
Property Search Records and Documents
Property search records and documents provide the underlying source files that support the Assessor’s parcel data. The documents include property record cards, recorded deeds, assessment rolls, tax bills, and historical transfer records. You can access these records to verify ownership, review valuation methodology, or confirm the legal description. Property records search by address is the starting point for retrieving any of these documents because it ties the document index to a specific parcel.
Property Record Cards
Property record cards summarize the parcel data in a single document, including ownership, valuation, building details, and land information. The card is updated after each assessment cycle and after any change to the property. Residents can also access official property records to verify current details. Property record cards are commonly used by appraisers, buyers, and title searchers as a snapshot of the official county file.
Deed Information
Deed information includes the grantor, the grantee, the transfer date, and the recording reference for each deed tied to the parcel. Property deed records search is a key step in title examinations and ownership verification. The portal links directly to the Recorder of Deeds index so you can retrieve the full deed image.
Assessment Records
Assessment records show the valuation history, classification decisions, and any appeal rulings tied to the parcel. Assessment records search is used by property owners preparing an appeal and by researchers analyzing valuation trends. The records include the supporting data used to justify the Assessor’s valuation.
Tax Records
Tax records include the tax bills, payment receipts, and delinquency notices tied to the parcel. Property tax records search is used by buyers and lenders to confirm the cost of ownership before closing. The records also show any tax liens that may affect the title.
Recorded Property Documents
Recorded property documents include deeds, mortgages, liens, easements, and any other instruments recorded against the parcel. The portal links to the Recorder of Deeds document index for retrieval. Recorded documents are the official public record of all legal interests in the property.
Historical Property Records
Historical property records include prior assessment rolls, past owner listings, and historical tax bills that may go back several decades. Historical property records search is useful for genealogy research, historical preservation, and long-term ownership analysis. The records are available through the Assessor’s office and the county archives.
Property Search Problems
Property search problems occur when the data you enter does not match what the Assessor has on file, or when the parcel is going through a recent update. The most common issues include a property not found error, an incorrect address, an outdated owner name, or a parcel number that has been merged or subdivided. The portal provides guidance for resolving each issue, and the Assessor’s office can help correct any errors. Most property search problems can be resolved by adjusting your search method or by contacting the office directly for assistance.
Property Not Found
A property not found error usually means the address, parcel number, or owner name you entered does not match the database. The most common cause is a misspelling, an outdated address, or a parcel that has been recently merged. How to find property records online when the parcel does not appear is best answered by trying a different search method or contacting the Assessor’s office.
Incorrect Property Address
An incorrect property address may appear on the portal if the parcel has a recent address change, a unit number update, or a street renaming. Address corrections are submitted to the county addressing authority and updated on the Assessor’s file after processing. You can request an address correction by contacting the Assessor’s office with the recorded deed or plat.
Incorrect Owner Information
Incorrect owner information appears when a recent deed has been recorded but not yet processed by the Assessor, or when the deed contains a clerical error. Owner corrections require a recorded deed showing the correct ownership. Property record correction requests are handled by the Assessor’s mapping and deed processing team.
Parcel Number Issues
Parcel number issues occur when a parcel has been split, merged, or renumbered after a subdivision plat. The Assessor assigns a new parcel number when the lot configuration changes. You can use the GIS map to locate the parcel visually if the parcel number search returns no results.
Recently Transferred Properties
Recently transferred properties may show the previous owner for several days or weeks after a deed is recorded, until the Assessor processes the transfer. The transfer will be reflected in the property record card once processing is complete. Recently transferred properties may also trigger a reassessment if the sale meets state requirements.
Unavailable Property Information
Unavailable property information occurs when the parcel file is being updated, when the system is undergoing maintenance, or when the record is restricted for legal reasons. You can contact the Assessor’s office during business hours for assistance with unavailable records. The office staff can pull the file directly while the portal is being updated.
Outdated Property Records
Outdated property records may appear between assessment cycles, when the file has not yet been refreshed for the new year. The Assessor updates records after each reassessment cycle and after each deed transfer is processed. Records flagged as outdated are usually refreshed within a few weeks of the triggering event.
- Double-check spelling and numeric characters in the search field.
- Try a different search method, such as switching from address to parcel number.
- Use the GIS map to locate the parcel visually if text searches fail.
- Contact the Assessor’s office during business hours for help with unavailable or outdated records.
Property Search and Related Records
Property search is one component of a broader public records system that includes owner searches, deed records, tax records, and GIS maps. Each system serves a different purpose, but all of them link back to the same parcel identifier maintained by the Assessor. Understanding how property search relates to other records helps you build a complete picture of any parcel in St. Louis County. The table below summarizes how the property search tool compares to each related public records system.
Property Search vs. Property Records
Property search is the action you take to locate a parcel using a text or map query, while property records are the documents and data tied to that parcel. The search returns the records, but the records themselves are stored in the Assessor’s database, the Recorder of Deeds index, and the Collector of Revenue billing system. A property records search is one part of the broader property search workflow.
Property Search vs. Property Owner Search
Property search focuses on a specific parcel or address, while property owner search focuses on a person or entity to find every parcel they own. You can use either method depending on whether you have an address or an owner name to start with. How to find a property owner by address and how to search property records by owner name are both supported by the Assessor portal.
Property Search vs. Address Lookup
Address lookup confirms the parcel tied to a specific street address, while property search can be initiated using other identifiers such as a parcel number or owner name. Address lookup is a subset of property search methods. Property lookup by parcel number is another subset that uses the unique parcel ID instead of the address.
Property Search vs. Deed Records
Property search returns current ownership and valuation, while deed records show the historical transfer documents that established ownership. A deed search is used to verify the chain of title and review the legal language of past transfers. The Assessor portal links directly to the Recorder of Deeds index for deed retrieval.
Property Search vs. Property Tax Records
Property search returns assessment data, while property tax records return billing and payment data. The two systems are linked by the parcel identifier, so a property tax information search usually begins with a property search. The Assessor handles valuation, and the Collector of Revenue handles billing and payment.
Property Search vs. GIS Map
Property search returns textual data, while the GIS map returns spatial data tied to the parcel. The two systems are integrated, so a property search by map click opens the same record card you would see through a text search. How to find a property on a GIS map is supported through the Assessor’s portal and the county GIS website.
| Search Type | Primary Identifier | Main Output |
|---|---|---|
| Property Search | Address, parcel, owner | Full parcel record card |
| Property Records Search | Parcel ID | Recorded documents and history |
| Owner Search | Person or entity name | List of parcels owned |
| Address Lookup | Street address | Matching parcel |
| Deed Records | Grantor or grantee | Recorded deed document |
| Tax Records | Account number | Billing and payment status |
| GIS Map | Map click or location filter | Parcel boundary and spatial data |

If the address yields multiple results, use the map view to pinpoint the exact lot. The map shows parcel boundaries and nearby streets, helping you confirm the correct property.
Let me find a property owner using the parcel number?
First, locate the parcel number on a deed, tax bill, or mortgage statement. Then go to the Assessor’s online portal and select the parcel‑number search field. Type the full number, including the leading letter (M, O, R, or S), and press Search. The result shows the primary owner’s name, mailing address, and any joint owners. You can also view the property’s legal description and recent sales data. Finally, click the “Print” button to keep a hard copy of the record.
How do I look up property tax details for a specific address?
First, enter the street address into the Assessor’s property‑lookup box. Next, the system displays the parcel ID linked to that address. Click the ID to open the tax‑detail page. Here you see the current taxable value, tax rate, and total amount due for the current year. The page also lists any exemptions that lower the bill. If you need past years, select the drop‑down menu and choose the desired tax year. You can download a PDF of the tax bill for your records.
Why might a parcel not appear in the online search?
There are a few common reasons a parcel does not show up. First, the address may be misspelled or missing a unit number, causing the system to miss the match. Next, the parcel could be newly created from a recent split, and the database has not yet been updated; updates occur nightly but can lag a few days. Then, the property might be located in a neighboring jurisdiction that uses a separate assessor site. Finally, if the parcel number was entered without the correct prefix letter, the search returns no result. In each case, double‑check the input or call the office for help.
Can I view a GIS map of a parcel while performing a property search?
Yes, the portal includes an interactive GIS map. After you locate the parcel ID, click the Map tab at the top of the page. The map displays the parcel’s boundary, nearby streets, and any overlay layers such as flood zones or school districts. You can zoom in to see the exact lot shape or switch to satellite view for a real‑world picture. A legend explains each symbol, and a print button lets you save a copy of the map. Using the map helps you confirm that the property you are researching matches the physical site.
