Fielding ADU Dallas builds attached ADUs, garage conversions, and room additions across Dallas. We hold every project to the Garrison Standard: a written price before work starts, permits pulled by the book, and a one-year written guarantee covering workmanship. Dallas has no citywide detached ADU ordinance, which means most backyard units are off the table and the real work happens inside the existing footprint of the home. Call (903) 342-8977 to talk through your lot and your options.
Why Dallas Homes Are Different
Dallas housing stock is dominated by single-family detached homes built after World War II, with heavy concentrations of ranch-style and traditional brick homes on larger lots in neighborhoods like Lake Highlands and Oak Cliff. Many of these houses have attached garages and backyards with enough room to expand, but the soil underneath them is expansive clay. That clay moves with moisture, and foundation movement is a real factor on nearly every Dallas addition or conversion we price.
The summers here are hot and humid, and the storm season is not a rumor. Any new living space needs real cooling capacity and storm-resistant detailing, not builder-grade shortcuts. The zoning picture is also specific to Dallas: detached ADUs are effectively prohibited in most single-family zones, but attached ADUs are allowed by right under the Dallas Development Code. That legal line between attached and detached drives nearly every ADU conversation we have in this city.
Our Main Dallas Services
Most Dallas homeowners call us about one of three projects: adding square footage to the main house, converting an attached garage into rentable or family living space, or building an attached ADU that satisfies the Dallas Development Code.
Room Addition Contractor in Dallas
A room addition in Dallas usually means extending the footprint of a ranch or traditional brick home, often at the rear. We handle foundation work carefully because expansive clay soils cause movement that will show up as cracks if the addition is not detailed correctly. Cooling load, roof tie-ins, and matching existing brick or siding are the details that separate a clean Dallas addition from one that looks bolted on. We price the work in writing before anything starts. See Room Addition Contractor in Dallas for the full scope.
Garage Conversion Contractor in Dallas
In many Dallas neighborhoods developed in the 1960s and 1970s, the original single-car attached garage is the easiest path to an ADU. The Dallas Development Code treats attached garage conversions as attached units, which sidesteps the city’s prohibition on detached backyard units. Shallow lot lines and existing utility easements often force creative thinking on setbacks, and we handle that variance work as part of the job. See Garage Conversion Contractor in Dallas for pricing and process.
ADU Builders in Dallas
Most Dallas ADU work we do is attached: a converted garage, a bump-out with a private entrance, or a reworked portion of the existing home with its own kitchen and bath. We are fluent with leading prefab and modular platforms including Mighty Buildings, Boxabl, and Plant Prefab, and we also build conventionally with James Hardie siding when that fits the lot and budget better. Every Dallas ADU gets the same written guarantee. See ADU Builders in Dallas for full details.

What pushes price up in Dallas is usually foundation work. Expansive clay means a lot of existing slabs have moved, and tying a new addition to a slab that is still moving is a warranty problem, not just an engineering one. We price all of this in writing before any work starts, so the number you approve is the number on the final invoice.

FAQs About ADU Company in Dallas
In most single-family zones, no. Dallas has no citywide detached ADU ordinance, and detached units are effectively prohibited in the majority of residential districts. Attached ADUs are allowed by right under the Dallas Development Code, which is why most of our work is garage conversions and attached additions. Call (903) 342-8977 and we will tell you what your specific lot allows.
Yes. Permits and documentation are part of every job we price. If your project needs a setback variance, which is the city’s written permission to build closer to the property line than the standard rule allows, we prepare and submit that paperwork as part of the written estimate. Nothing starts without the permit board filled.
After the estimate and written price are approved, we schedule based on current crew availability and permit processing times at the city. Most Dallas projects start within two to six weeks of approval. Call (903) 342-8977 for a free estimate and we will give you a real schedule, not a promise we cannot keep.
