Get your free estimateFast, Reliable ADU Builders Across Lackland AFB
Adding an ADU on Lackland AFB means dealing with something most San Antonio contractors never think about: base security pre-clearance for every worker and vehicle. We handle that paperwork before we ever show up, so your project doesn’t stall at the gate. A detached studio ADU in Lackland AFB typically runs $165,000 to $240,000, while a garage conversion or JADU starts closer to $95,000. Call (430) 258-2928 for a written line-item price before any work begins.
Lackland AFB’s housing stock is mostly mid-century ranch homes and duplexes built for military families. Those homes share predictable bones: 2×4 framing, slab foundations, and electrical panels that are almost always undersized for a modern ADU. That’s useful. It means we can price your project accurately before we open a single wall, because we’ve already seen what’s behind the next one.
Why Benson ADU San Antonio Is Lackland AFB’s Preferred ADU Builders Company
We’re part of the Relay Home Co. family, founded 2006. Every job we run, including here on Lackland AFB, operates under The Relay Visibility Guarantee: a written price before work starts, real-time tracking through the build, and a 365-Day Done Right Promise in writing. If something isn’t right within a full year, we make it right. No phone tag, no chasing a foreman, no “we’ll get back to you.”
Our ADU Builders team knows what base life actually means. Homeowners here get PCS orders with eight weeks’ notice. That changes how we schedule. We sequence work so an ADU can be locked up and weathertight fast, even if interior finishes continue after you’ve relocated. We also coordinate with the base housing office on inspection scheduling, because we know that office runs on its own clock.
Every technician who steps onto Lackland AFB is background-checked and arrives in uniform. You know exactly who’s walking onto your property. That matters more on a military installation than anywhere else. A live person answers our phone around the clock. Not an answering service. A person. Call (430) 258-2928 and you’ll talk to someone who can actually answer your question.
ADU Design in Lackland AFB
ADU Design in Lackland AFB starts with two constraints most designers never consider: wind-rating requirements from San Antonio’s storm codes, and the base housing office’s own design review standards. We design to both, from day one. The design phase typically costs $4,000 to $9,000 as a standalone service, and it’s credited back against construction when you build with us. You get a permit-ready plan set, not a napkin sketch.
Site Plans and Setbacks
Your lot on Lackland AFB has specific setback lines, utility easements, and drainage patterns that determine where an ADU can physically sit. We survey, measure, and produce a site plan that the base approves before you’ve committed to a full build. Most military housing lots in this area have generous rear yards, which gives us real flexibility on placement.
Wind-Rated Structural Design
San Antonio sits in a moderate wind zone, and ADU plans here need engineered tie-downs, anchor bolts on closer spacing, and roof-to-wall connections that a standard plan from a website won’t include. Our design package includes the wind-load calculations and anchoring schedule the structural reviewer on base requires. You don’t pay a surprise engineering fee later.
Backyard ADU in Lackland AFB
Backyard ADU construction in Lackland AFB typically runs $165,000 to $240,000 for a detached one-bedroom unit, depending on finish level and whether you choose a prefab panel system or full site-built construction. For homeowners facing frequent relocations, this is the highest-ROI build on the property: a rentable unit that holds value whether you stay or PCS. We offer curated prefab options from Abodu, Cover, and Tuff Shed, alongside fully custom site-built ADUs.
Prefab vs. Site-Built on Base
Prefab ADUs from Abodu and Cover arrive as panelized or modular components, which means fewer days with a crew on your property and fewer gate pre-clearances required. That’s a real advantage on Lackland AFB. Site-built gives you total control over layout and finishes but adds two to four weeks to the schedule. Both meet wind-rating requirements when installed correctly.
Rental-Ready Finishes
Most Lackland AFB homeowners build an ADU for rental income, either while stationed elsewhere or after relocating. That means the unit needs to rent quickly and hold up to tenants. We spec James Hardie siding, LVP flooring, and moisture-resistant drywall as standard. These are landlord-grade choices, not builder-grade shortcuts.
Trusted Brands We Service in Lackland AFB
We’re authorized to build with leading prefab and materials brands including Abodu, Cover, Tuff Shed, and James Hardie. Being authorized matters: it means the manufacturer trained our crews on their exact installation specs, and it means warranty claims get processed through a direct channel, not a third party. For Lackland AFB customers, we stock common replacement components and finish materials locally, so a warranty fix or small repair doesn’t wait on a two-week freight delivery. You can research every brand we carry independently. We want you to.
Common ADU Builders Problems We See in Lackland AFB Homes
- Aluminum wiring spliced with copper. Mid-century base housing built in the 1950s and 60s often contains aluminum branch circuits. Opening a wall for an ADU connection triggers a code requirement to address every splice we expose, which means a panel upgrade and proper Al/Cu connections before inspection will pass.
- Rotted sill plates from failed window flashing. San Antonio’s driving rains find every gap in older flashing. We regularly find sill plates that look fine from the outside but crumble when probed. We price the reframe as a written change order before we touch it, never as a surprise bill at the end.
- Undersized electrical panels. A 100-amp panel that served a 1958 duplex half cannot carry a new ADU’s load. The base housing office’s inspection will not sign off on an ADU fed from an overloaded panel. We include the panel upgrade in your initial written price whenever the existing service is below 200 amps.
- Missing wind-rated anchors. Older Lackland AFB homes were built before current wind codes. When we connect an ADU to an existing structure or build within proximity to one, the anchoring on the original structure often needs to be brought up to current standards to pass structural review.
Pricing for ADU Builders in Lackland AFB, TX
Here’s what you should expect to pay in this market. A JADU or garage conversion runs $85,000 to $130,000. A detached studio ADU runs $140,000 to $190,000. A one-bedroom detached unit with premium finishes runs $180,000 to $240,000. A full custom two-bedroom ADU starts around $220,000 and can reach $320,000 with high-end materials and site work.
What moves the number on Lackland AFB specifically? Gate pre-clearance adds one to two days of coordination per major phase, which is a real labor cost. Wind-rated anchoring and structural engineering add $3,000 to $7,000 versus a standard off-base build. And open-wall code upgrades, like panel replacements or framing repair, are the biggest variable. We write allowances into every contract so you know the range before we start, and any change order is priced and approved in writing before we touch the work. Call (430) 258-2928 for a free written estimate.
We also serve Lackland AFB homeowners in every corner of the base, from the housing areas off Military Drive to the newer developments near the Medina Annex.

FAQs About ADU Builders in Lackland AFB
Plan on one to two additional days per major construction phase for worker and vehicle pre-clearance through base security gates. That’s paperwork, background verification, and scheduling coordination that off-base projects in San Antonio never face. We submit clearance requests before the crew arrives, so the delay happens on paper, not with a crew standing idle at the gate. Call (430) 258-2928 and we’ll walk you through exactly how clearance works for your specific project.
The three most common are electrical panel replacement (when existing service is below 200 amps), aluminum wiring remediation at every splice we expose, and framing repair where moisture damage or poor original construction is found. Current NEC and local building codes require any opened wall to be brought up to code before inspection. We write allowances for these upgrades into your contract so they’re priced before demolition starts, not discovered after.
Yes. San Antonio’s storm codes require engineered roof tie-downs, anchor bolts on specified spacing, and specific roof-to-wall connections for detached ADUs. A builder using standard off-base methods will fail the structural review. Our design package includes wind-load calculations and the anchoring schedule the base reviewer requires. The added engineering cost runs $3,000 to $7,000.
Yes, but it requires base housing office approval and may trigger fire separation requirements between units. A duplex half converted to an ADU typically runs $85,000 to $130,000 depending on the condition of the existing unit and the scope of the electrical and plumbing separation. This is one of the most common requests we get from Lackland AFB homeowners, and we handle the approval paperwork as part of the project.
We stop work, photograph the issue, and price the fix as a written change order before we touch anything else. You approve the number before we proceed. On a mid-century ranch off Military Drive, our crew opened a 1958 duplex wall and found aluminum wiring spliced with copper, plus a rotted sill plate from failed window flashing. We priced the panel upgrade and reframing in writing, got approval, and completed the fix to current NEC with a wind-rated anchor package. That’s how every surprise gets handled. Call (430) 258-2928 for a free estimate, and we’ll put the whole plan in writing before a single shovel turns.
