Inside the City Limits

For these seven, the City of Round Rock's rule applies: no permit for a house re-roof or siding replacement, and so no city inspection. What differs is the age of the houses and, downtown, the historic rules.

Place	Houses date from	What sets it apart
Round Rock West	1970s to late 1980s	Oldest subdivision roofs and wood-era trim.
Downtown Round Rock	Historic core	Exterior changes need a Certificate of Appropriateness.
Forest Creek	1990s	East-side clay, houses about 30 years old.
Teravista	Early 2000s	Lies between Round Rock and Georgetown.
Behrens Ranch	2001 on	West side, first roofs met the 2023 storm.
Mayfield Ranch	2008 on	Roofs were young in 2023; trim is aging now.
University Heights and Vizcaya	2010s and 2020s	Plank siding on the side walls.

Outside the City Limits

A Round Rock mailing address does not put a house in the City of Round Rock. These three places answer to someone else.

Place	Who governs	What sets it apart
Brushy Creek	Williamson County; a utility district; deed restrictions	Unincorporated, 20,953 residents in 2020.
Hutto	City of Hutto	Seven miles east, nearly all built since 2000.
Georgetown	City of Georgetown	Roofing permit, contractor registration, final inspection.

Clay to the East, Limestone to the West

Geology splits this area as well. The Balcones Escarpment divides Williamson County along a line from Jarrell through Georgetown to Round Rock. East of it lie the deep, dark clay soils of the Blackland Prairie. West of it the ground is hilly, with thin soil over limestone.

For a roof the difference is small. For siding and trim it matters more, because clay that swells and shrinks moves a slab a little each season, and rigid boards and caulk joints show it.
