Whether a fence needs a permit depends on the city or county your property is in, not on the address on your mailbox. Katy and its neighbors sit across several counties and dozens of municipal utility districts, so the answer changes within a few miles. This page shows where to check for each area we serve and what usually triggers a permit. We do not list permit fees or rules that we have not verified.
Who to ask, by area
The table shows what each official source says as of September 2026. Several sources are silent on residential fences, so a blank does not mean no permit is needed. Some entries come from the city's own code or pages; where an official source was unavailable we say so.
| Area | What we found | What to do |
|---|---|---|
| City of Katy | Permits and Building, 281-391-4830. The city's permit list does not mention fences. A third-party site says none is needed, which we could not confirm. | Call the city, and first confirm the address is inside city limits. |
| Unincorporated Fort Bend County (Cinco Ranch, Seven Meadows, Aliana and others) | County Engineering, 281-342-3411. Its permit list covers floodplain work, larger structures, fill and driveways, and does not mention fences. | Ask County Engineering, and check floodplain status. |

What usually triggers extra rules
- Height: many places allow a taller fence in the back than in the front.
- Pool barriers: commonly governed by local building codes and often need a self-closing, self-latching gate.
- Corner lots: visibility triangles near intersections can limit fence height.
- Gates with operators: electrical and safety requirements may apply to automatic gates.
- Retaining walls and columns: structural rules apply above certain heights.
- Flood plains and drainage: fences that cross a drainage easement or floodway may be regulated.
For neighborhood rules see the HOA guide. For pool barriers see pool fences. For lot lines see property lines and easements.
