Do Not Mix St. Louis County with the City of St. Louis
This is the most common local mistake. St. Louis County and the independent City of St. Louis are separate jurisdictions with separate assessor, collector and recorder systems.
| If the Property Is… | Use These Records | Why It Matters |
|---|---|---|
| In St. Louis County | St. Louis County Assessor, Collector, Recorder and GIS. | County taxes, locator numbers, deeds and GIS are handled by county systems. |
| Inside the City of St. Louis | City Assessor, City Collector and City Recorder. | City pages use different account/parcel searches and different offices. |
| Near the city/county border | Confirm through official map, tax bill or address jurisdiction. | Mailing city, ZIP code and “St. Louis” address wording can be misleading. |
What to Do If St. Louis County Assessed Value Looks Wrong
Do not begin with “my taxes are too high.” First decide whether the issue is property data, valuation, classification, exemption, tax district or a tax-bill payment issue.
Property data
Square footage, year built, land size, property type, condition and improvements can affect value.
Similar sales
Use similar municipality, property type, size and condition when comparing values.
Tax vs value
The Collector handles bills. The Assessor handles assessment value and property-record data.

Common St. Louis County Property Records Problems and Fixes
| Problem | Likely Cause | Best Fix |
|---|---|---|
| No Assessor result by address | Too much address text, unit number, punctuation, direction word or wrong municipality. | Try only street number + main street name, then confirm municipality and locator number. |
| Owner name gives too many results | Common last name, trust, LLC, spouse name or prior owner. | Use address, locator number or GIS map to narrow the record. |
| Tax bill does not match expected property | Wrong locator number, wrong tax year or city/county confusion. | Match locator number, address, owner clue and jurisdiction before paying. |
| Need deed proof | Tax or Assessor record is being used as ownership proof. | Use Recorder of Deeds and verify recorded legal documents. |
| Payment made but receipt not found | Posting delay, wrong account, or searching the wrong jurisdiction. | Check confirmation, bank/card proof and call Collector if status is urgent. |
| Boundary or easement question | GIS map is being treated like a survey. | Use deed, plat, legal description, title work and licensed surveyor review. |
Property Records Tips That Save Time in St. Louis County
These tips help homeowners, buyers, agents, title researchers and landlords checking properties in Clayton, Florissant, Chesterfield, Ballwin, Kirkwood, Creve Coeur, Maryland Heights, Hazelwood, Mehlville and unincorporated St. Louis County.
Save the locator number first
It is the easiest way to move between Assessor, Collector, Recorder and GIS workflows without mixing up parcels.
Check city vs county before anything
A “St. Louis” mailing address does not always mean St. Louis County. Confirm jurisdiction before searching.
Use GIS for map confidence
GIS can confirm parcel location and nearby context, especially where city names and ZIP codes overlap.
Search Recorder by party names
Deed systems often work better with grantor/grantee and date clues than with a modern street address.
Look for releases after liens
A lien, deed of trust or assignment may have a later release or satisfaction. Search forward before assuming it remains active.
Do not pay from memory
Always confirm tax year, locator number, owner clue and amount due from the official county portal before payment.
