ADU Construction in Georgetown, TX
Guest houses, in-law suites, and accessory dwelling units for Georgetown homeowners, from historic Old Town to Sun City, built from Austin.
ADU Construction in Georgetown, Texas
Georgetown, a Williamson County city about 30 miles north of Austin, splits neatly into two very different building worlds, and HN Construction & Remodeling builds accessory dwelling units in both. Around the historic square and Old Town, early-1900s homes sit on mature lots where an ADU has to respect period detailing and, in the historic district, added design review. Out in Sun City, Wolf Ranch, and Cimarron Hills, newer master-planned builds raise questions about HOA rules and lot coverage instead.
That split shapes what an ADU means here. In Sun City, a 55-and-older community, homeowners most often want an attached in-law or caregiver suite for aging in place, subject to the community's deed restrictions. In Old Town, a detached backyard cottage or a garage-to-guest-house conversion has to sit comfortably behind a historic home. All of it is permitted through the City of Georgetown, and HN Construction handles the permit, any historic review, and a fixed line-item written estimate.

Old Town history versus Sun City rules
Georgetown is really two ADU markets. In the historic Old Town district, adding or converting a structure can trigger design review, so the ADU's roofline, siding, and windows need to read as a compatible companion to an early-1900s home. In Sun City and Wolf Ranch, the homes are newer and the constraints are HOA and deed restrictions plus the City of Georgetown's ADU and lot-coverage rules, with many owners building an attached suite so a parent or caregiver can live close by. HN Construction works both sides, matching historic character downtown and navigating master-planned HOA approvals to the north around Berry Creek.
What to know about adu construction in Georgetown
- Old Town's early-1900s homes and historic district can require design review, so an ADU's exterior has to match the period
- Sun City is a 55-plus community, so ADUs there are usually attached in-law or caregiver suites and are subject to deed restrictions
- Newer Wolf Ranch and Cimarron Hills builds sit under active HOAs that regulate ADU size, rentals, and appearance
- All ADU permits run through the City of Georgetown, which sets size, setback, and lot-coverage limits
- Detached backyard cottages fit larger Old Town and acreage lots; attached suites fit tighter master-planned lots
How much does adu construction cost in Georgetown?
Georgetown ADU costs sit within the greater-Austin ranges: roughly $150,000 to $350,000 and up for a detached unit, with attached in-law suites and garage conversions typically lower. Historic Old Town projects can carry added detailing costs to match a period home, while Sun City suites are often simpler attached builds. HN Construction prices each Georgetown ADU as a fixed line-item written estimate.
