St. Louis County Property Search 2026: Records, Tax & Maps
Looking for property ownership, assessed value, real estate taxes, deeds or parcel maps in St. Louis County, Missouri? Start with the county’s official public record systems. Different departments maintain different records, so choosing the correct portal can save time.
This guide shows how to search by address, owner or parcel number, locate tax information, find recorded documents and use the county GIS map.
Missouri’s City of St. Louis operates separately from St. Louis County. A property with a St. Louis mailing address may not be inside the county’s jurisdiction. Confirm the property’s actual location before using a search portal. This article covers St. Louis County, Missouri, not St. Louis County, Minnesota.
Quick Answer: Where to Search
For a St. Louis County property search, begin with the official real estate search for property and assessment details. Use the county property tax inquiry for bills and payment information, the Recorder of Deeds for recorded instruments, and county GIS for parcel mapping and geographic context.
Have the complete property address or locator number available. An exact parcel number is particularly helpful when several properties share similar street names or addresses.
Official St. Louis County Property Search Tools
St. Louis County does not use a single public portal for every land record. Assessment data, taxes, recorded documents and mapped parcel boundaries have different purposes and may be updated on different schedules.
Real Estate and Assessor Search
Use the county real estate system to identify a parcel and review available assessment, ownership and property characteristics.
Open Assessor Search ↗Property Tax Inquiry

Open Tax Inquiry ↗Recorder of Deeds
Search recorded land instruments, including deeds and other documents affecting real property. Full document images or certified copies may involve charges.
Find Recorded Documents ↗GIS Property and Parcel Maps
Explore property locations, zoning information and other geographic data using the St. Louis County Geospatial Data Center.
Explore County GIS ↗How to Search St. Louis County Property Records
The easiest search begins with a street address, although a parcel locator can be more precise. The following workflow helps confirm that you are looking at the correct property before relying on its valuation or tax information.
Open the official real estate search
Use the county assessor search link above. The portal may open in a separate application from the main county website.
Enter identifying information
Try the complete street address or property locator. If the portal offers additional search fields, use the available owner or other identifiers as appropriate. Follow the fields currently displayed on the official site.
Match the correct parcel
Compare the address, municipality, parcel identification and property details. Similar addresses can exist in nearby communities, so do not rely solely on a street name.
Review assessment information
Check available land and improvement values, tax-year references, property classification and other details. Record which assessment period the figures represent.
Check taxes and recorded documents separately
Open the tax inquiry for billing or payment questions and the Recorder of Deeds for recorded legal instruments. These records answer different questions.
Save the relevant record identifiers
Keep the parcel number, tax year, recorded instrument reference or other source details for future review. Verify important legal or financial facts with the responsible department.
Which Property Records Can You Find?
A property record search may provide several kinds of information. Availability depends on the public system, the record’s age and whether the information has been processed and published.
| Record Type | What It Helps Establish | Best Source |
|---|---|---|
| Property identification | Parcel number, location and identifying details | Assessor |
| Ownership listing | Owner information shown in the assessment database | Assessor |
| Assessed value | Value used in the property assessment process | Assessor |
| Real estate tax | Tax bills, account information and available payment history | Tax Inquiry |
| Deeds and instruments | Recorded transfers and other property-related instruments | Recorder of Deeds |
| Parcel location | Mapped boundaries and nearby geographic features | GIS |
| Zoning context | Published zoning geography and planning information | GIS / Planning |
Public assessor information is useful for initial research, but it is not a substitute for a title examination, survey or official certification when one is legally required.
St. Louis County Property Tax Search
Property tax records help answer practical questions: Is a real estate tax bill available? Which tax year does it cover? Does the account show a balance, a payment or a prior-year item requiring attention?
The county’s property tax inquiry system provides a starting point. Search by the identifiers accepted by the current portal and confirm that the result refers to the correct real estate parcel rather than a personal property account.
Current Tax Bill
Look for the relevant tax year and the amount shown on the official account. An assessment figure alone does not establish the tax amount due.
Payment History
Review any available payment entries, receipts and account status. Processing delays may affect when a recent payment appears.
Past-Due Questions
If the account displays an unpaid or delinquent amount, contact the county’s revenue department for the current amount required and applicable procedures.
A tax bill, assessment date and payment deadline are not interchangeable. Confirm the 2026 billing schedule, exact balance and any payment fees directly on the St. Louis County revenue system. Do not use deadlines displayed on the City of St. Louis tax website for county property.
Assessed Value vs. Market Value in St. Louis County
Two values appearing in property research may describe different things. The assessor’s value belongs to the assessment process; an asking price or estimated market value is not necessarily the amount used to calculate property tax.
| Term | Meaning | What to Check |
|---|---|---|
| Appraised value | An estimate of property value used in assessment administration | Valuation date and property details |
| Assessed value | The value produced under applicable Missouri assessment rules | Classification and tax year |
| Tax amount | An amount calculated under applicable taxing and billing rules | Official tax bill and adjustments |
| Sale price | The consideration reported for a transaction where available | Transaction date and source |
What if the Assessor’s Property Details Are Wrong?
First identify the specific discrepancy. An incorrect building description, parcel association, ownership listing or valuation concern may require a different review process.
Save the property’s locator number and supporting evidence, then contact the county assessor through its official website. Assessment appeals can have strict filing windows, and a general correction request should not be assumed to preserve an appeal deadline.
St. Louis County Deed and Ownership Search
The assessor’s listed owner can help you begin researching a property, but it does not establish clear legal title. To examine recorded transactions, use the St. Louis County Recorder of Deeds.
Recorded documents can include warranty deeds, quitclaim deeds, deeds of trust, releases and other real estate instruments. The presence of a document in the index does not by itself establish that every possible lien or title issue has been resolved.
Researching a Property Transfer
- Identify the parcel and property address.
- Open the Recorder of Deeds search resource.
- Use the search fields supported by the selected recording system.
- Compare the parties, date and document reference.
- Request an appropriate copy when necessary.
When the Deed Search Is Not Enough
If you are buying property, resolving an inheritance, refinancing or investigating a lien, consider obtaining a professional title examination. A public index search is useful but may not capture every legal issue affecting ownership.
Search access and document-copy charges depend on the service used. Confirm current fees before ordering records.
St. Louis County GIS Parcel Maps and Zoning
The St. Louis County Geospatial Data Center publishes mapping resources for county property information, zoning and other geographic topics.
GIS is particularly useful when an address is unclear, a parcel has an unusual shape, or you need to compare a property with surrounding roads and land-use information.
Useful GIS Research
- Locate the parcel geographically.
- Examine available parcel outlines.
- Review published zoning layers.
- Compare surrounding streets and geographic features.
- Identify the parcel for further assessor research.
Understand Map Limitations
A GIS parcel line is generally intended for mapping and information purposes. It should not be treated as a legal boundary survey.
For building setbacks, development permission or a boundary dispute, consult the applicable planning authority and a qualified surveyor when appropriate.
A parcel’s zoning designation describes a land-use classification. It does not automatically authorize a particular project. Confirm permitted uses, overlays and approvals with the authority that has jurisdiction over the property.

If a search does not return the expected record, check the property jurisdiction and identifiers before concluding that the record is missing.
| Problem | Possible Explanation | Next Step |
|---|---|---|
| No result for the address | Address formatting, recent changes or the wrong jurisdiction | Try the locator number and confirm the parcel is in St. Louis County. |
| Owner name appears outdated | A recent transfer may not yet appear in the assessment database. | Compare the recorded deed and ask the assessor about its update process. |
| Tax amount differs from assessed value | Assessment and tax calculations serve different purposes. | Use the actual tax bill for the relevant year. |
| Deed is missing | Search fields, indexing or record availability may differ. | Try alternative party names or contact the Recorder. |
| GIS boundary looks incorrect | Mapping data may not reflect survey-level precision or recent changes. | Request clarification from county GIS and consult survey documentation. |
| Portal does not load | Service interruption, browser restrictions or a changed portal route | Start at the county’s official main website and navigate to the relevant department. |
Official St. Louis County Property Record Resources
Use the following government resources for county-specific property information. For in-person appointments, records requests or current office contact information, consult the corresponding official department page rather than relying on an outdated third-party directory.
What to Prepare Before Requesting Property Records
Online searches generally require fewer details than formal requests for certified documents. The information below will help you communicate with the appropriate department.
- Property address: Complete street address, including any directional prefix or unit information.
- Parcel locator: Use the county’s identifying number when available.
- Owner information: Useful when the official record search permits party-name lookups.
- Tax year: Specify the year needed for bills, receipts or account research.
- Document information: Names, approximate recording dates and instrument references help narrow deed requests.
- Requested format: Explain whether an informational online record, an uncertified copy or a certified document is needed.
Public lookup pages may be accessible without charge, but document images, certified copies, payment processing and certain research services can involve fees. Check current official charges rather than assuming every service is free.

Does the county search include the City of St. Louis?
No. The City of St. Louis is a separate jurisdiction with its own assessment, tax and recording systems. Check the property’s actual jurisdiction before choosing a portal.
How do I dispute an assessed property value?
Review the county assessor’s current assessment and appeal guidance. Gather the parcel number, notice and relevant evidence, and confirm the filing deadline and required procedure with the responsible authority.
Why does my property show an old owner?
Property databases can update at different times. Compare available recorded documents with the assessor’s listing and ask the relevant county department about discrepancies.
Can GIS maps confirm my exact property boundary?
No. GIS maps are geographic reference tools and are not necessarily survey-grade evidence. Legal boundary questions may require recorded plats, surveys or professional assistance.
