More Than a Place to Park — A Structure Built for How You Actually Use It
Most of the garages we build in Tarrant and Denton County aren't just for cars. Some are workshops. Some are heated hobby spaces. Some are storage solutions for families who've outgrown the house. And some are the first phase of a two-part plan: build the garage now, add the apartment above later.
Whatever the intended use, the build process is the same: proper foundation, proper framing, proper electrical, exterior finish matched to the primary residence. A detached garage is a permanent structure on your property, it requires a permit, and it should be built like one.
Standard Detached Garage (1–3 car)
Concrete slab foundation. Wood framing. Roof pitch and shingle matched to the main house where city requires architectural compatibility. Electrical subpanel, lighting, and standard outlets. Garage door rough opening framed to your door size. Exterior siding and trim to match the primary residence.
Workshop / Climate-Controlled Garage
All of the above plus additional insulation (walls and ceiling), mini-split HVAC for year-round use, higher-amperage electrical service for equipment, additional circuits and 240V outlets where needed. For homeowners who use the space heavily.
Garage with Future Apartment Above
Foundation and framing engineered to carry a second-floor load. Floor system built to residential living standards. Subpanel sized for a future full electrical service above. Plumbing rough-in for a future bathroom or kitchen if desired. Building this capacity in during the garage phase costs significantly less than retrofitting it later.

Yes, if the original garage is built to support it. That means engineering the foundation and floor system to carry residential load, sizing the electrical subpanel for a full apartment service, and roughing in plumbing if you want a bathroom above. Adding this capacity during the original garage build costs far less than retrofitting.
Most cities in Tarrant County require a minimum 5-foot setback from the rear and side property lines for detached accessory structures. Some cities require more. HOA documents may specify additional minimums. We verify the applicable setback requirements for your specific address on the site visit.
