AfterFast, Reliable Home Additions & ADU Across Converse
A home addition or ADU in Converse, TX typically runs $45,000 to $130,000 for room additions, with detached ADU construction landing between $90,000 and $220,000 depending on size, site prep, and utility runs. Most projects take 3 to 6 months from permit to final inspection, though garage conversions move faster. If you’re weighing whether to add on or build out back, call us at (877) 610-1318 and we’ll walk the property with you before you spend a dime.
We work all over 78109, from the older streets off FM 1516 to the new subdivisions going in toward the county line. The soil here is the first thing we look at, and if you’ve lived in Converse long, you already know why. Blackland Prairie clay moves. It heaves in wet winters and shrinks in dry summers, and any addition tied to an older slab has to account for that before we frame a wall. Tom Barrett and his sons have been working this soil since 1998, and they’ll tell you straight what your foundation will and won’t allow. That conversation costs you nothing.
Why Barrett & Sons Construction Is Converse’s Preferred Home Additions & ADU Company
We’re not a franchise dispatching strangers. When you call Barrett & Sons about an addition in Converse, the person who answers is here in Bexar County, and the crew that shows up carries the Barrett name. Tom’s sons run the crews themselves most days. Ask around. The license number is published, the address is public, and if something isn’t right after the job, the 90-Day Done Right Promise means one call brings Tom back. That’s written on every contract.
Converse homeowners keep calling us for a reason that has nothing to do with slick sales. We put every scope, every allowance, and every price change in writing before work starts. No surprise invoices. No “the allowance ran out” conversation at the end. The permit inspector works for you, not for me, which is exactly why I like him on the job. We pull permits on every eligible project and we don’t skip inspections to save a day. In a town where half the homes date to the 1980s and 1990s, that matters more than people realize until their first project goes sideways.
Our Home Additions & ADU Services in Converse
ADU Design & Permitting
The planning side trips up more Converse homeowners than the construction does. Bexar County has setback rules, impervious cover limits, and utility easement requirements that vary by neighborhood and lot age, and Converse’s newer subdivisions often carry deed restrictions on top of county code. We handle drawings, engineering, and the full permit package so you’re not guessing. If you’re exploring a Home Additions & ADU project, starting with a site walk and a straight conversation about what your lot allows saves months of false starts.
Garage Conversion ADU
Garage conversions in Converse typically run $30,000 to $80,000, and on older military-era tract homes they almost always uncover something the original builder left behind: sloped slabs, undersized electrical panels, or a foundation that shifted during a drought year. We account for that from the first estimate, not after demo starts. Converting an attached garage into a rentable unit or an in-law suite is the fastest path to an ADU here because the shell already exists.
New Detached ADU
A detached ADU in Converse runs $90,000 to $220,000 once you factor the slab, utilities trenching, and standalone electrical service. On Blackland clay, the slab is not optional and not cheap, but it’s the difference between a building that settles evenly and one that cracks at the corners in three years. We pour early mornings in summer to beat the 100-degree afternoons that wreck concrete cure times, and we engineer the slab for the soil, not for a generic spec.
Junior ADU & Interior Conversion
Junior ADUs, attached interior conversions, and bump-outs in Converse often make more sense than a detached build when the goal is housing an aging parent or adding a quiet office. These run within the $45,000 to $130,000 range depending on whether you’re converting existing square footage or adding new. In older homes off Toepperwein and Kitty Hawk, we regularly see unlevel floors from clay movement once walls come open, and we address that before framing proceeds.

Trusted Brands We Service in Converse
Windows and doors on Converse additions take a beating from Texas sun and clay-driven frame movement, so we don’t install mystery brands off a van. We work with Simonton, Ply Gem, and PGT, because when a window rack in a settling wall, you want a manufacturer that stands behind its product and a crew that stands behind its install. We order directly for each Converse job, which keeps lead times honest and warranty claims simple if anything ever fails. You can look these brands up, and you should.
Common Home Additions & ADU Problems We See in Converse Homes
- Foundation movement before framing. In Converse’s older neighborhoods off FM 1516, homeowners deferred foundation watering during droughts, so the clay pulled away from perimeter beams. Any addition tied to that slab needs a foundation assessment first, or you’re building square footage on a moving base.
- Unlevel floors hiding in 1980s and 1990s tract homes. Original slab-on-grade construction from the military-housing boom era was built fast and slab-on-grade, and forty years of shrink-swell cycles have left interior floors out of level by an inch or more in places. That shows up the moment a remodel opens walls.
- Undersized electrical panels from the original build. Many Converse homes from the 1980s and 1990s carry 100-amp panels, and an ADU with its own kitchenette or a room addition with real HVAC needs more than that. We plan for panel upgrades in the estimate instead of discovering it mid-job.
- Summer heat compressing concrete and roofing schedules. Northeast Bexar County regularly exceeds 100°F from June through September, which shortens the viable pour window. We schedule early-morning concrete work and stage materials to avoid heat damage, and we don’t pretend the calendar doesn’t matter.

FAQs - Home Additions & ADU in Converse
How fast can you get to Converse for a home addition estimate?
We typically schedule estimates in Converse within a few business days, and because our crews live and work in the northeast Bexar County corridor, site visits don’t require a long lead time. Call (877) 610-1318 and you’ll get a real person on the line, not a voicemail box. There’s no trip charge inside the county.
Do you handle permits for ADUs in Converse?
Yes, we handle the full permit package for Converse ADU projects, including drawings, engineering, and the inspection schedule. Permits are pulled on every eligible job, and inspections get signed before we call the project done. The permit inspector works for you, not for me, which is exactly how it should be.
What does a detached ADU cost in Converse compared to nearby cities?
A detached ADU in Converse runs $90,000 to $220,000, which tracks closely with Windcrest and Universal City because the soil conditions, labor market, and county permitting process are the same. The clay soil in this corridor often adds slab engineering costs that flat-ground cities don’t face, but that’s a function of the land, not the contractor.
Do you offer a warranty on home additions in Converse?
Every Barrett & Sons job comes with the 90-Day Done Right Promise, written on the contract, not buried in fine print. If it’s not done right, Tom comes back and makes it right, one call. We also stand behind the manufacturer warranties on every window, door, and finish product we install.
Can you look at an older Converse home before we commit to an addition?
Yes, and on 1980s and 1990s slab-on-grade homes in Converse, we recommend it. A foundation assessment before any above-grade work is standard practice for us on older lots because the Blackland clay under this part of Bexar County moves enough to affect framing. We’ll tell you what’s needed, in writing, before you spend anything on construction.
Our Home Additions & ADU Services in Converse
Room Additions
Room additions in Converse usually mean adding a primary suite, a second living area, or a dedicated home office to a 1980s or 1990s tract home that wasn’t designed to grow. We tie into the roofline, match the brick veneer where it matters, and pour the foundation for the clay, not for a textbook. The range runs $45,000 to $130,000 depending on square footage and finish.
Second Story Additions
Going up instead of out makes sense on smaller Converse lots where setback rules leave little room to expand sideways. A second story addition runs within the $45,000 to $130,000 range but moves toward the upper end because the existing first-floor framing and foundation have to be verified for the added load. We engineer before we demo.
Sunrooms & Enclosed Patios
Sunrooms and enclosed patios in Converse walk a line between “addition” and “conversion,” and the cost usually lands at the lower end of the $45,000 to $130,000 range. The Texas sun is merciless on glass, which is why we install Simonton and Ply Gem units rather than whatever the supply house has on sale. A sunroom that turns into an oven by 2 p.m. isn’t usable space.
ADU Site Prep & Utilities
Site prep in Converse means trenching for water, sewer, and electric through clay that fights the trencher, and in some of the older neighborhoods off FM 1516 it means discovering utility runs that predate modern record-keeping. We handle the underground work, the slab, and the panel upgrade if your existing service can’t carry the load. This is not the part of the job to bid low and hope for the best.
