Home Additions & ADU in Fort Worth - One Fixed Price, Permits Handled

Fast, Reliable Home Additions & ADU Across Fort Worth

If you’re weighing a home addition or ADU in Fort Worth, the real question isn’t whether you can find a contractor. It’s whether the one you hire understands what happens under your slab when the clay finally gets a good rain after a drought. We do, because we’ve built on it. A home addition here runs $45,000 to $130,000 and an ADU typically runs $90,000 to $220,000, but price means little on soil that heaves. Call Tom Barrett at (877) 610-1318 and you’ll get a straight conversation, not a script.

Barrett & Sons Construction has worked Fort Worth’s neighborhoods long enough to know that River Oaks, Forest Hill, Haltom City, and Benbrook each have their own soil quirks and code paths. We don’t drive in from another metro and guess. We pull permits, sign for inspections, and put every allowance in writing before a single board is cut. The crew you’ll see is Tom’s own people, background-checked and named on the truck.

Key Takeaways

• A home addition in Fort Worth runs $45,000-$130,000. An ADU runs $90,000-$220,000. Garage conversions land between $30,000 and $80,000.

• We answer the phone live, 24/7. One number: (877) 610-1318.

Why Barrett & Sons Construction Is Fort Worth’s Preferred Home Additions & ADU Company

Tom Barrett founded this company in 1998 and put his name on it. That means something in Fort Worth. When we tell homeowners in the 76110 zip code that their pier-and-beam bungalow needs beam leveling before an addition can be framed off the back, we’re telling them something we’ve seen on a hundred nearby lots, not something we learned from a YouTube video.

Our Home Additions & ADU team is owner-operated and small enough that Tom himself answers the phone more often than not. The 90-Day Done Right Promise is printed on every contract: if something isn’t right, one call brings Tom back to make it right. We don’t bury that promise in fine print. We don’t have fine print.

Fort Worth customers ask the same thing: will the price change after the crew shows up? Our answer is no, and it’s written down. Every change order arrives on paper before nothing moves. The permit inspector works for you, not for me. That’s why I like him. We also publish Tom’s name and license number. Look it up before you sign anything.

Our Home Additions & ADU Services in Fort Worth

Here’s the cross-section of what we actually do in this city, with the local angles that matter to your house and your lot.

ADU Design & Permitting

Building an attached or detached ADU in Fort Worth means navigating the city’s zoning rules for accessory dwelling units, parking requirements, and in neighborhoods like Fairmount and Ryan Place in 76110, an extra layer of design review. We handle the drawings, the applications, and the meetings so you don’t have to learn city code on your own. Every permit gets pulled and every inspection gets signed before we call the job done.

Garage Conversion ADU

A detached garage from the 1940s or 1950s can be a conversion waiting to happen in Fort Worth, especially in the 76109 and 76110 belts where original pier-and-beam garages still stand. But before anyone pours a new floor or runs electrical, we check what the clay has done to the stem walls and footing. Garage conversions in Fort Worth run $30,000 to $80,000, and we give you that range in writing before work begins so there’s no surprise at the end.

New Detached ADU

A new detached ADU on an open section of your Fort Worth lot starts with geotechnical reality: the Blackland Clay in 76108 and 76111 shrinks during drought and swells after a hard rain. Our slabs are engineered for that movement, with proper drainage and foundation design before framing ever starts. You’ll see named premium materials on the plans, not mystery brands off a van.

Junior ADU & Interior Conversion

Not every Fort Worth homeowner has room for a detached structure. A junior ADU inside your existing footprint - a finished basement, an enclosed sunroom, or a garage wing with a private entrance - can add a rental unit or a place for family without the full expense of new construction. We also tie in Bathroom Remodeling in Fort Worth work when an interior ADU calls for a new bath, which almost every conversion does. The plumbing, electrical, and egress have to meet current code, and we make sure they do with inspections on record.

Other Additions We Build in Fort Worth

The ADU work is one piece of what we do. We also frame room additions off the back of Fort Worth’s postwar ranch houses, lift second story additions onto the craftsman bungalows that are so common in Ryan Place, and close in sunrooms and enclosed patios on the stronger lots where the soil tests come back clean. If the addition expands the kitchen, we work with the Kitchen Remodeling in Fort Worth side of our company to make sure cabinets, countertops, and appliances land in the right place the first time.

Trusted Brands We Service in Fort Worth

We don’t install materials you can’t verify. On hardscape and exterior work tied to additions, we run premium brands like Techo-Bloc and Cambridge Pavers. On patios and walkways, Oldcastle and Quikrete are the names we trust and the names we’ll show you on the quote. Those products hold up in Fort Worth’s heat, and we stock common local parts and materials so we’re not waiting on a warehouse in another state when your addition’s exterior ties into existing brick or stone.

Common Home Additions & ADU Problems We See in Fort Worth Homes

• Slab heave on Blackland Clay. A foundation poured on Fort Worth’s shrink-swell clay can move several inches between drought and deluge cycles. We see cracked slabs, lifted sidewalks, and pulled masonry joints that tell us the addition’s slab needs deeper engineering than the original house got in, say, 1985.
• Pier-and-beam rot in older inner-city homes. The 1920s-1950s bungalows in 76104, 76109, and 76110 often sit on original piers that have settled or rotted. Before a structural addition goes up, the framing underneath has to be leveled and the moisture barrier replaced, or the new work inherits the old movement.
• Historic overlay slowdowns. Fairmount and Ryan Place in 76110 are inside Fort Worth’s Historic and Cultural Landmarks overlay. Exterior changes and additions need a Certificate of Appropriateness before permits can be issued. We know the process, the review board, and the timeline, which is not something a national company’s call center can walk you through.
• Barnett Shale subsidence spots. Fort Worth permitted gas wells inside city limits during the 2000s and 2010s, and localized subsidence shows up as small dips and stress lines on some inner-city lots. When we bid an addition, we look at the lot’s history, not just the house’s age.
