Search by Owner, Address, Locator Number or Subdivision
St. Louis County gives multiple ways to search property data. Use the search method that matches the information you already have.
Search by address
Address search is best for everyday users. Start with the house number and street name. If the search does not work, remove unit numbers, punctuation and extra direction words.
Search by owner name
Name search is useful when you know the owner but not the property address. Try last name first for individuals and exact entity name for LLCs, trusts or companies.
Search by locator number
Locator number is the best identifier for exact research. It helps prevent confusion when similar street names appear across multiple municipalities.
Search by subdivision
Subdivision search can help when researching neighborhood lots, development areas or older property descriptions where addresses are not enough.
Assessor Records, Values and Real Estate Data
The St. Louis County Assessor is responsible for valuing real estate and personal property throughout the county. For real estate research, the Assessor search is the main place to review public property data and assessment details.
Use the Assessor record when you want to confirm the property, understand the county’s value information or prepare for valuation questions.
| Assessor Field | What It Helps You Check | Why It Matters |
|---|---|---|
| Locator number | Unique property identifier in county records. | Best field for tax, map and office questions. |
| Owner display | Current owner shown in public assessment data. | Useful for public lookup and buyer research. |
| Property address | Official address listed in county data. | Helps match property tax, deed and GIS records. |
| Assessed value | Tax assessment value used in local tax calculation. | Important for tax estimates and appeal review. |
| Subdivision / municipality | Location and jurisdiction context. | Taxes and local services can differ by municipality. |

St. Louis County vs City of St. Louis Records
This is one of the most common mistakes. St. Louis County and the City of St. Louis are separate government record systems. A property in Clayton, Chesterfield, Florissant, Kirkwood, Ballwin or unincorporated St. Louis County should use county tools.
A property inside the independent City of St. Louis should use city assessor, city recorder and city tax systems instead. Do not mix these systems when searching records or paying taxes.
| Property Location | Use This Guide? | Correct Starting Point |
|---|---|---|
| St. Louis County municipality or unincorporated area | Yes | St. Louis County Assessor / Recorder / Collector tools. |
| City of St. Louis | No | City of St. Louis Assessor, Recorder and Collector systems. |
| Unsure | Check first | Search GIS by address and confirm jurisdiction before paying or ordering copies. |
