Get your free estimateFast, Reliable ADU Builders Across Georgetown
Adding a detached ADU, garage conversion, or room addition in Georgetown means navigating three different rulebooks: the city’s 2019 by-right ADU code, HOA architectural standards in communities like Sun City and Teravista, and the preservation board’s material rules in Old Town. Fielding ADU Austin handles all three, with a written price before any work starts and a full year of written guarantee on every build. We’re ADU Builders who show up in uniform, pull permits by the book, and stand behind the work through The Garrison Standard. Call (361) 309-9568 for a free estimate on your Georgetown project.
Why Fielding ADU Austin Is Georgetown’s Preferred ADU Builders Company
Georgetown homeowners call us because we don’t hand over a vague bid and then reopen the number once we hit limestone. We walk the lot, check the HOA guidelines, and write a price that covers what we can see and what we know to expect from Georgetown’s soil and code environment. If something hidden turns up, you approve the change in writing before we touch it. That’s how The Garrison Code works: show up in the window, price in writing, by the book, leave it clean, stand behind it for a year.
Reed Calloway leads our Georgetown work, and every crew member on your property is background-checked and in uniform. Dispatch and scheduling coordinate from our Austin office; crews serve Georgetown locally. When you call, a live person answers, 24 hours a day, seven days a week. No voicemail, no callback queue.
We’ve built detached ADUs in Sun City with zero-threshold ramps and wide doorways to satisfy Del Webb’s accessibility mandates, and we’ve matched limestone and metal roofing in Old Town to pass preservation review. We know which neighborhoods hit complications and which ones approve fast. That local knowledge shows up in the estimate, not after the dig.
ADU Construction in Georgetown
ADU Construction in Georgetown is rarely a simple frame-and-finish job. The 2019 code change legalized ADUs by right in all single-family zones, but that same code triggers electrical, structural, and energy upgrades in existing structures when walls come open. A permitted ADU in Georgetown often means upgrading the main panel, adding shear wall, and bringing the existing home’s connection points to current code. We’ve built enough of them to know which upgrades are real, which are inspector-specific, and which ones a homeowner should plan for before signing.
Garage Conversions and Existing Structures
Working with a Garage Conversion Contractor in Georgetown means the inspector will look at the original framing, the slab, and the electrical service when converting a garage or enclosed porch into an ADU. Homes from the 1970s through the early 2000s often have undersized panels and door headers that never carried a permit. We inspect before we quote, and we write allowances for what the inspection suggests. The written price covers the realistic scope, not the fantasy one.
The Permit Path in Georgetown
Georgetown’s permit review differs by neighborhood. In Old Town, the preservation board reviews exterior materials before the building permit clears. In Sun City, Del Webb’s architectural committee has its own checklist. We submit plans with both rulebooks in mind so the review doesn’t stall. Our projects in Georgetown have gone through this process enough times that we know what gets flagged and what doesn’t.
Detached ADU in Georgetown
Detached ADU construction in Georgetown is the most common project we build, and it’s also the one most affected by rocky limestone soil. A backyard cottage on a Georgetown lot means excavating through limestone for the foundation, which most contractors price as a surprise after the dig starts. We price it from the start. A typical detached ADU in Georgetown runs $180,000 to $320,000 for a finished unit with a kitchen and bath, before permit fees and depending on site conditions, accessibility features, and the exterior finish requirements your HOA or the preservation board mandates.
Sun City Requirements
In Sun City, Del Webb’s architectural standards require specific exterior finishes that match the main home, and accessibility features like wider doorways and ramps are often mandatory even when the client didn’t ask for them. In Sun City, we built a detached ADU for a couple whose caregiver needed accessible living space. Our crew installed wide doorways and a zero-threshold ramp to match Del Webb’s aging-in-place requirements, while managing rocky limestone soil for the foundation. The project got approved only after we submitted stone veneer and metal roofing samples that matched the main house. This is standard Sun City procedure, not an exception.
Old Town and Historic Standards
Old Town Georgetown has its own layer: the preservation board requires ADUs to match original materials like limestone and metal roofs. Standard fiber cement siding won’t pass review there. If you’re planning a modern ADU with James Hardie siding in Old Town, that’s not going to clear the preservation board. We’ll build it with materials the board approves, or we’ll tell you before you pay for plans that won’t pass. That conversation costs nothing and saves months.
Trusted Brands We Service in Georgetown
We’re fluent with the prefab and modular platforms Georgetown homeowners already research: Abodu in Georgetown and Cover for panelized prefab detached units, plus conventional construction using James Hardie siding and Tuff Shed-style structures for budget-conscious builds. Matching the right method to your lot, your HOA, and your budget is part of the estimate. We coordinate foundation work, utility stubs, and the manufacturer’s installation requirements so the prefab path doesn’t stall at the permit counter.
Common ADU Builders Problems We See in Georgetown Homes
- Limestone excavation change orders: Georgetown lots sit on shallow limestone. Contractors who don’t price excavation hit the rock, then hand the homeowner a foundation change order. Our estimates include the excavation allowance for Georgetown soil before the first shovel goes in.
- HOA review stalls: Master-planned communities like Teravista and Sun City have architectural guidelines that run parallel to city permits. Skipping the HOA submission adds weeks or months to the permit path. We submit HOA materials and city plans together.
- Old Town material rejections: Plans submitted to the preservation board with standard siding get rejected. Limestone veneer and metal roofing are the expected materials in the historic district, and we plan for that cost from day one.
- Sun City accessibility retrofits: Del Webb’s aging-in-place standards require wider doorways and a ramp in most cases. If that’s not in the original bid, the project stalls. We include accessible design by default in Sun City, not as an add-on.

FAQs About ADU Builders in Georgetown
Yes, Georgetown requires a building permit for any detached ADU, and a separate electrical permit for service work. Code upgrades trigger when we open walls, modify the electrical panel, or extend plumbing to the new structure. A garage conversion usually triggers panel, insulation, and egress upgrades. We price those in the written estimate. Call (361) 309-9568 and we’ll walk your specific home.
We price limestone excavation as a line item from the first estimate, not as a change order after the dig hits rock. Georgetown’s limestone sits close to the surface in most neighborhoods, which means pier drilling or rock excavation for the foundation. Our estimates include a soil-based excavation allowance so the number you approve is the number on the final invoice.
Sun City’s Del Webb standards require wider doorways, a zero-threshold entry, and a ramp in most detached ADUs, even when the client didn’t request them. Yes, we include those features by default in Sun City projects. We submit the accessibility plan with the architectural review package so it doesn’t delay the permit. Call (361) 309-9568 for a Sun City-specific quote.
No. The Old Town preservation board requires exterior materials that match the original character of the district, typically limestone veneer and metal roofing. James Hardie siding will not pass review there. We build with board-approved materials and price that difference upfront. Call (361) 309-9568 to discuss your Old Town lot.
We inspect before we quote, and we write allowances into the contract for what the inspection suggests. If our crew opens a wall and finds outdated wiring or failed waterproofing that wasn’t visible, we stop, show you the condition, and price the fix in writing before we proceed. The work continues only after you approve the number. That’s the written-price-first policy, every time.
