Building in Katy
What do people build in Katy?
Katy sits where Harris, Fort Bend and Waller counties meet, so the first question on any job is which county and which city line you are in. Shops, detached garages and RV and boat storage are our most common Katy builds, along with warehouse and flex space along the I-10 and Grand Parkway growth corridor.
Families on larger lots want a shop or RV cover, and businesses near the freeway want simple warehouse and flex shells.

Three counties, one city
Inside Katy city limits the City of Katy issues permits. Outside them your parcel may fall under Harris, Fort Bend or Waller County, and each has its own process. We confirm this before design.
HOAs in master-planned communities
Communities like Cinco Ranch, Cane Island and Elyson have architectural review rules that commonly limit detached buildings. Get HOA approval in writing before ordering steel.
Drainage districts west of town
Waller County notes that sites inside the Brookshire-Katy Drainage District need additional permitting. Flat prairie ground also makes slab elevation and site drainage worth planning early.
FAQ
Metal building questions in Katy
What size shop is most popular in Katy?
A 40x60 with 14–16 ft eaves is the most common request. It fits a pickup, a boat or camper and a workbench, with room left over. On smaller lots a 30x40 garage-shop is a good fit.
My Katy address is in Waller County. Does that change anything?
It can. Waller County handles permitting for unincorporated areas through its County Engineer, and sites in the Brookshire-Katy Drainage District need additional permitting. We will check your parcel and line up the right approvals.
Can you build a covered RV or boat port in Katy?
Yes. Open-sided covers and enclosed RV garages with 14 ft+ doors are both common here. HOAs often have the final say, so we draw the building and help you submit it.
