Senior and Military Courtesy: No-Cost Permit Review on Your First Project
If you’re a senior or active-duty or retired military homeowner in Austin, we’ll review your permit path at no cost on your first ADU or addition. That means we check zoning, setback variance requirements (the city’s written permission to build closer to the property line than the standard rule allows), and what Austin’s permitting office will ask for before you commit a dollar.

First-Time Customer: Free Site Visit and Build Method Match
We walk your Austin lot and match the right build method to your budget and site conditions. That could mean a prefab platform like Abodu, Cover, Dvele, Mighty Buildings, Boxabl, or Plant Prefab, or a conventional build with James Hardie siding. You get a straight recommendation, not a sales pitch for whatever we happen to have on the shelf.

What Our Offers Actually Cover
Most Austin homeowners shopping ADU specials want three things: a real price, a real schedule, and a real guarantee. Here’s what Fielding ADU Austin writes down before work starts.
- Written price first. The number you approve on day one is the number on the final invoice. No change orders unless you ask for a change.
- Background-checked, uniformed crew. Every person on your site has been verified before they set foot on your property. You know who’s working on your home.
- The Garrison Standard, in writing. Workmanship defects covered for 365 days. We return and correct them at no charge.
- Permit fluency. We know what Austin requires for ADUs, garage conversions, and additions. We pull permits and pass inspections.
Why We Run Specials Without Cutting Corners
Fielding ADU Austin is an independently owned and operated member of the Garrison Partners family. Garrison Partners has been building to The Garrison Standard since 2006. That standard has five parts: show up in the window, price in writing, by the book, leave it clean, and stand behind it for a year. An offer never changes any part of that code.
Reed Calloway, our owner, puts it this way: a special should help a homeowner in Austin start the conversation, not make them wonder what got left out of the bid. So our offers cut the entry cost, not the scope or the materials.
Cost Ranges for Austin ADU and Garage Conversion Projects

Here’s what we tell Austin homeowners before permit fees. A garage conversion in Austin typically runs $85,000 to $140,000 depending on whether the existing slab, electrical service, and roofline cooperate. A detached ADU using a prefab platform like Boxabl, Abodu, or Plant Prefab typically runs $120,000 to $180,000. A conventional site-built ADU with James Hardie siding typically runs $160,000 to $240,000 in Austin’s current market. Room additions range widely based on foundation work and roof tie-in.
These numbers shift with your lot, soil conditions, and Austin’s permit fees. Call (361) 309-9568 for a written estimate on your specific property. The estimate is free and the number you approve is the number you pay.
