The three-county split
The Katy area is one of the fastest-growing suburban corridors in the United States, with growth expanding outward from the original Katy city limits in all directions. The city of Katy itself is small (pop. roughly 22,000), but the broader Katy community — the ZIP codes that carry the Katy name — spans parts of Fort Bend County to the south, Harris County to the east (where the original city is primarily located), and Waller County to the west and northwest.
Each county has its own separate District Clerk (felonies and major civil cases) and County Clerk (misdemeanors) — Texas's two-clerk system means each county actually has two separate court record access points. A Harris County search for a subject whose Katy address is in Fort Bend County will return nothing — not because there is no record, but because it was filed in the wrong county system. Texas DPS statewide covers all three counties simultaneously in one search.
Which county is my address in?
| Katy area | County | District Clerk | County Clerk |
|---|---|---|---|
| Original Katy city limits, central Katy (77449, 77450 ZIP codes) | Harris County | Harris County District Clerk (hcdistrictclerk.com) | Harris County Clerk |
| South Katy, Cinco Ranch, Sugar Creek areas (parts of 77494) | Fort Bend County | Fort Bend District Clerk | Fort Bend County Clerk |
| West Katy, Brookshire area (77423, outer 77494 ZIP) | Waller County | Waller County District Clerk | Waller County Clerk |
ZIP codes are an unreliable county indicator for Katy — the 77494 ZIP in particular crosses the Fort Bend-Harris county line. The most reliable method is the Texas county boundary map or a county GIS parcel lookup using the specific street address. Texas DPS statewide eliminates the pre-selection problem entirely.
Texas DPS statewide is the correct Katy starting point
The Texas Department of Public Safety criminal history name search covers all 254 Texas counties — including Fort Bend, Harris, and Waller — without county pre-selection. It is the only single tool that covers all three Katy counties simultaneously. Run it first, then use the county identity it reveals to route document requests to the correct clerk.
Accessing records in each county
Harris County
Harris County District Clerk at hcdistrictclerk.com provides online case access for felony and civil records covering the central Katy and original city limits area. Harris County Clerk handles misdemeanor matters separately. This is Texas's largest county and has one of the most developed online record access systems in the state. See our Harris County guide for full detail.
Fort Bend County
Fort Bend District Clerk and County Clerk both provide online access for their respective record types, covering the south Katy and Cinco Ranch areas. Fort Bend is one of the fastest-growing Texas counties with a robust South Asian and Chinese community in the Sugar Land corridor that extends northward into Katy. See our Fort Bend County guide for full detail.
Waller County
Waller County District Clerk covers the western Katy and Brookshire area. Waller County is smaller than Harris or Fort Bend and has a more rural character west of the Katy urban core. Online access is more limited than Harris or Fort Bend — direct clerk contact may be needed for full document access.

Frequently asked questions
Which county is "Katy, TX" in?
Katy spans all three: Fort Bend County (south Katy, Cinco Ranch), Harris County (central Katy, original city limits), and Waller County (west Katy, Brookshire area). The 77449, 77450, and 77494 ZIP codes can each contain addresses in more than one county. Texas DPS statewide covers all three simultaneously and is the correct starting point when county is uncertain.
Can I use the ZIP code to figure out which county a Katy address is in?
Not reliably. The 77494 ZIP code in particular crosses the Fort Bend-Harris county line. ZIP codes follow postal routes, not county boundaries. A GIS parcel lookup using the specific street address through Harris, Fort Bend, or Waller county assessor portals is the reliable method for confirming county. Texas DPS statewide eliminates the need for county pre-selection entirely.
Can I use these searches for jobs, housing, or insurance decisions?
No. The services discussed on this page are not consumer reporting agencies and the information here is not a consumer report. They should not be used for employment, tenant screening, insurance underwriting, credit, or any other purpose regulated by the Fair Credit Reporting Act.
