Katy
West along I-10, across three counties, almost all of it Katy ISD.
Living in Katy
Katy is west of Houston along I-10, and it spans three counties — Harris, Fort Bend and Waller. The ZIP codes on this page are 77449, 77450, 77493 and 77494. Which county a house sits in changes its tax rate and its appraisal district, so it is one of the first things to establish rather than one of the last.
Nearly all of it is zoned to Katy ISD, which is the single biggest reason people search here, and the district runs well beyond the city limits. It also redraws attendance zones regularly as new campuses open. A Katy mailing address does not guarantee Katy ISD, and a Katy ISD address does not guarantee a particular campus. Check the current zone for the exact property.
The housing stock runs from 1980s subdivisions near the old town center to master-planned development still under construction out west. Newer sections almost always sit inside a Municipal Utility District, which levies its own rate on top of the county and school rates — often the difference between two homes that list for the same price.
Flooding is the other thing to get right here. Parts of Katy flood and parts do not, the reservoir pools affected specific neighborhoods in 2017, and the maps have been revised since. Ask for the current flood designation, the full claims history and an insurance quote during the option period.
