AfterFast, Reliable Home Additions & ADU Across Converse
Home additions and ADU construction in Converse typically run $45,000-$130,000 for most room additions, while a fully permitted detached ADU starts around $90,000. If you live off FM 1516 or in one of the older military-era neighborhoods near Randolph AFB, you already know the real question isn’t just cost: it’s whether your slab can take the load. That’s why every addition we price in Converse starts with a foundation assessment, not a glossy brochure. Call (877) 610-1318 and we’ll walk the site with you, tape measure in hand, before any numbers go on paper.
Why Barrett & Sons Construction Is Converse’s Preferred Home Additions & ADU Company
We’re not a franchise dispatching crews from three states away. Tom Barrett founded this company in 1998, and his sons run the crews that show up in Converse. When you call, a live person answers, 24 hours a day. Not a voicemail box, not an out-of-state call center. The person who prices your addition is the same person you’ll see at the hardware store on Saturday.
Converse homeowners have a particular reason to be skeptical of contractors. The older neighborhoods near Randolph were built fast in the 1980s and 1990s, and plenty of families there got burned by builders who cut corners and disappeared. We do the opposite: Tom publishes his name, his address, and his license number. Look it up before you sign anything. Every price change arrives as a written change order before a single nail moves. And every job carries the 90-Day Done Right Promise in writing. If it isn’t right, one call brings Tom back.
Our Home Additions & ADU Services in Converse
We handle the full range of Home Additions & ADU work, from a 200-square-foot Junior ADU carved out of an existing interior to a ground-up detached unit with its own utilities. Here’s what most Converse homeowners call us for first.
ADU Design & Permitting
Converse sits inside Bexar County, which means your ADU has to meet both city and county code requirements. We pull every permit and sit through every inspection, because the permit inspector works for you, not for me. For an older Converse lot, that usually means a drainage plan tied to your specific clay soil conditions and a setback variance if the lot is tight. We handle the paperwork from first survey to final sign-off.
Garage Conversion ADU
Converting a garage in Converse usually makes more sense than building new, especially in the 1980s brick-veneer tracts where the garage slab is often the most stable concrete on the property. We’ve converted dozens of two-car garages into one-bedroom units with their own entrances, kitchens, and baths. Expect to spend $30,000-$80,000 depending on whether you need plumbing stubbed in from the street or can tie into existing lines.
New Detached ADU
A new detached ADU in Converse typically runs $90,000-$220,000. The wild card down here is the clay. Blackland Prairie soil expands and contracts hard through our drought-to-deluge cycles, so we over-engineer the foundation beams and often pour piers deeper than code minimum. Summer heat regularly cracks 100°F in Converse, which shortens the viable concrete-pour window. We schedule early-morning pours so the concrete cures before the slab surface bakes.
Junior ADU & Interior Conversion
If you’ve got an underused den, formal living room, or oversized laundry room, a Junior ADU can add a rental unit or in-law suite without touching your roofline. This is often the fastest path for Converse families bringing aging parents closer. At $45,000-$100,000 all-in, it’s the most affordable ADU route, and many of these projects never require a variance since the envelope doesn’t change.

Trusted Brands We Service in Converse
We build with materials you can look up, not mystery brands off a van. On Converse additions we regularly install Simonton windows for their Texas-heat-rated glass packages and PGT impact-rated units where wind and hail exposure demands them. If you’re adding a sunroom or enclosed patio, we lean on Ply Gem for the framing and glazing systems. Our suppliers keep local stock for the Converse area, which means fewer weeks lost waiting on millwork when your lead time is already stretched by the building cycle.
Common Home Additions & ADU Problems We See in Converse Homes
- Slab movement from Blackland clay. In older Converse neighborhoods off FM 1516, deferred foundation watering during droughts pulls clay away from perimeter beams. By the time we open walls for an addition, floors are often unlevel and drywall is cracked. We address the slab before we frame above it.
- Permit surprises from previous owners. Military transfers meant many Converse homes changed hands quickly. We frequently find unpermitted patio covers, carports, or enclosed garages that need legalizing before a new addition can tie in. We handle the retroactive permits and bring everything current.
- Door frames racked by seasonal clay movement. The shrink-swell cycle in northeastern Bexar County pushes and pulls on brick veneer. A door that sticks in August and swings loose in February is a Converse signature. Our crews know how to frame openings that tolerate movement without binding.
- Undersized electrical panels from the 1980s. Many tract homes built in the 1980s and 1990s went up with 100-amp panels. Add a kitchen, bathroom, and mini-split to an ADU and you’ve outgrown it. We upgrade to 200-amp service as part of the project, on permit and on inspection.

FAQs - Home Additions & ADU in Converse
Most room additions in Converse run $45,000-$130,000 depending on size, story height, site conditions, and utility upgrades. A 300-square-foot single-story addition on an accessible lot might start around $65,000. A second story that requires reinforcing the first floor will land higher. Call (877) 610-1318 for a written line-item quote on your specific scope.
Yes. Every eligible job we build in Converse includes permits pulled and inspections signed. That’s not optional with us. We file with Bexar County and the City of Converse as required, and we sit through every inspection from foundation to final. The permit inspector works for you, not for me. Call (877) 610-1318 if you’re wondering whether a previous contractor left you with unpermitted work, we can help sort it out.
A garage conversion ADU usually runs 8-12 weeks from start to certificate of occupancy. A new detached ADU runs 4-7 months depending on foundation work, utilities, and weather. Converse summers can push past 100°F, which affects concrete pours and exterior work; we schedule pours early and sequence interior trades during the hottest weeks. Call (877) 610-1318 with your timeline and we’ll map out a realistic schedule.
It doesn’t, unless the scope changes and you approve it in writing first. When we open walls on a 1980s Converse tract home and find slab movement or hidden water damage, we stop and bring you a written change order with exact numbers before we proceed. The allowance that isn’t on paper is a surprise waiting for a date. That’s a rule we’ve kept since 1998.
Yes. Every completed project carries the 90-Day Done Right Promise in writing. If anything isn’t done right, one call brings Tom back to make it right. No claim forms, no finger-pointing. Call (877) 610-1318 and you’ll get Tom or one of his sons on the phone, not a call center.
