Building a fence in Katy: local facts

Checked October 7, 2026

ZIP codes: 77493, 77494

The City of Katy itself covers parts of 77493 and 77494. Many Katy mailing addresses are outside the city, in unincorporated Harris, Fort Bend or Waller County (Firethorne, for example, is unincorporated Fort Bend). There the county rules apply: Harris County needs no permit for a residential fence outside the flood hazard area, and Fort Bend County requires a development permit for any work in a floodplain.

Ground and weather

Around Katy the USDA maps Katy fine sandy loam: about 10 inches of sandy loam over firm clay loam, with moderate shrink-swell. The bigger problem is water. The county soil survey says poor drainage is the most severe limitation of these prairie soils, so posts sit in wet ground after heavy rain and wood rots at the ground line.
During Harvey in 2017, record flooding ran along upper Buffalo Bayou and Cane Island Branch through the City of Katy, 1 to 2 feet above the 2016 Tax Day flood. The flood control district estimated 630 flooded homes in the Harris County part of Katy alone.

Questions from Katy homeowners

What color can I stain my fence in Firethorne?

Wood Defender Coronado semi-transparent, or a product the Modifications Committee considers equivalent. You need written approval of an application with a stain sample before you stain. The 2014 amendment replaced the old clear-sealant-only rule.

Can I replace the iron view fence on my Cane Island lake lot with wood for privacy?

No. Cane Island requires 5-foot tubular steel view fences next to greenbelts, lakes and amenity areas, and its guidelines say homeowners may not switch from a view fence to a wood fence.

Who fixes the shared fence with my neighbor in Cane Island?

Shared fences alternate pickets in and out, and each owner is responsible for the pickets facing their own yard. Replacing single pickets, or no more than one section, with identical parts does not need ACC approval.
