Katy
Incorporated City of Katy across Harris, Fort Bend, and Waller counties, not the larger unincorporated area that uses Katy mailing addresses
When someone says “Katy,” ask whether they mean the City of Katy or the much larger area that uses a Katy mailing address. The incorporated city crosses Harris, Fort Bend, and Waller counties and includes a historic core, established neighborhoods, newer subdivisions, townhouses, apartments, and commercial development along I-10. Lot sizes, setbacks, street patterns, and deed restrictions can change from one block or subdivision to the next. I-10 is the main connection toward the Energy Corridor and Houston. The county line also matters because it affects appraisal, taxes, elections, records, and some public services. Before relying on the name in a listing, confirm that the property is inside city limits, then check the county, school assignment, HOA documents, drainage and flood information, and current road conditions for the address.

Things to understand
- The incorporated City of Katy is smaller than the broader area that uses Katy postal addresses; confirm the city-limit line before relying on City services, taxes, or regulations.
- City parcels can be in Harris, Fort Bend, or Waller County, so appraisal, taxation, elections, records, and some public services depend on the property's county.
- Historic-core blocks, established neighborhoods, newer subdivisions, and infill can have different lot dimensions, setbacks, deed restrictions, and HOA obligations.
- School assignment, drainage and flood context, and roadway conditions should be checked for the specific address using current official maps and records.
