A zoning verification letter may be requested through the Citizen Serve online portal. A zoning verification letter is a document from the City verifying the following:
- The property is located within the City of Lake Saint Louis;
- The zoning designation of the property;
- Verification that a particular use is permitted within the property’s zoning district;
- Zoning regulations if applicable to the property;
- Status of open zoning violation cases against the property.
If you'd like the City to include specific language or information in the zoning verification letter, please specify that in your request. Special requests may be granted by staff on a case-by-case basis.
