Georgetown ADU construction site in Williamson County
📍 Serving Georgetown, Round Rock, Leander & Williamson County

Williamson County ADU Service Hubs

Georgetown ADU Builders delivers local municipal zoning compliance, soil engineering, and custom ADU building across Georgetown and all primary suburban communities in Williamson County, Texas.

The rules change by parcel, not by city.

Each community below sets its own limits on size, height, rear setback and whether a second dwelling can be rented at all. Two houses on the same street can sit in different zoning districts, and the district is what governs.

So treat these pages as the starting point rather than the answer. The address is what settles it, and confirming that costs you nothing.
