Where is Katy? Zip codes & counties
Katy sits about 30 miles west of downtown Houston along I-10, and it is unusual in that it spans three counties — Harris, Fort Bend and Waller. Its four residential zip codes are 77449, 77450, 77493 and 77494. Which county is each one in? 77449 is entirely Harris County; 77450 is mostly Harris with a portion in Fort Bend; 77493 is mostly Harris with portions reaching into Waller and Fort Bend; and 77494 flips the other way — roughly 89% Fort Bend County, about 7% Harris and about 4% Waller. Two houses on the same Katy street can sit in different counties, so confirm the county on the appraisal district record before you rely on a tax estimate. (77491 and 77492 are PO-box only.)
The simplest way to keep the four straight is to split Katy on two roads — I-10 and the Grand Parkway (SH-99):
- 77449 — north of I-10, east of the Grand Parkway
- 77493 — north of I-10, west of the Grand Parkway
- 77450 — south of I-10, east of the Grand Parkway
- 77494 — south of I-10, west of the Grand Parkway
Best neighborhoods in Katy
Katy is almost entirely master-planned, so buyers usually shortlist by community rather than by street: Cinco Ranch, Seven Meadows, Grand Lakes, Kelliwood, Nottingham Country, Falcon Landing, Firethorne, and newer developments including Cane Island, Tamarron, Elyson and Young Ranch.
One thing worth checking early: most of Katy is zoned to Katy ISD, but communities on the far west and south sides can fall into Lamar CISD instead. Confirm the zoned campus for the specific address before you fall in love with a house.
