ActiveYards Home Additions & ADU: The San Antonio Owner’s Guide
ActiveYards home additions and ADU construction in San Antonio typically runs $45,000 – $130,000 installed, depending on square footage, foundation work, and whether you’re building out or up. Most owners find us after their original addition starts showing its age: a sagging roofline where the old framing tied into the existing structure, moisture wicking up through a slab that was never properly sealed, or a converted garage that’s suddenly too hot in July because the original contractor skipped insulation between the old garage walls and the new living space. If you’re reading this, chances are you have an ActiveYards structure that’s failing, and you want to know if it’s worth repairing before you pour more money in. Here’s the honest answer: in most San Antonio cases, a well-built repair or re-tie of the structural connections runs far less than a tear-down, but there are times when the framing is too far gone and a partial rebuild makes more sense. We’ll walk you through exactly how to tell which situation you’re in.
Which ActiveYards Models This Applies To
ActiveYards makes several addition and ADU configurations, and the failure points differ by how the unit was originally anchored. The attached single-story additions (the ones that extend off the back or side of a primary home) tend to fail first at the ledger board connection where the new roof ties into the old exterior wall. The detached ADU structures (standalone units built on a separate slab) more commonly develop slab settlement issues, especially on San Antonio’s expansive clay soils, which heave and contract with our wet-dry cycles. The garage conversion kits struggle with insulation boundaries and humidity control because the original garage slab sits lower than the house slab and lacks a proper vapor barrier.
To identify exactly what you have, look for the ActiveYards label plate, usually mounted on the structural beam inside the addition or on the electrical subpanel door. It will list the series and the date of manufacture. Take a photo of that plate and have it ready when you call. If the label is missing or painted over, measure the interior ceiling height and the span of the longest wall. Original ActiveYards additions from the mid-2000s ran 8-foot flat ceilings with 2×6 framing at 24-inch centers; later production switched to 2×4 at 16-inch centers with a steeper roof pitch. That difference matters, because the repair approach changes based on what’s actually holding up your roof.
One thing to be clear about: Sawyer Remodel San Antonio is an independent general contractor, not affiliated with ActiveYards. We work on ActiveYards structures all the time, but we are not a factory warranty provider. What we do is fix what’s failed and build additions and ADUs that hold up better than the original. For OEM ActiveYards components, we can source them when they’re still available; when they’re discontinued, we spec quality aftermarket equivalents that meet or exceed the original engineering.

Signs Your ActiveYards Home Addition or ADU Is Failing
- Cracks running diagonally from the corners of windows and doors. On San Antonio clay, this is almost always slab movement, not a settling house. The addition’s foundation moves independently of the main house, and the crack pattern tells you which direction it’s moving.
- A visible gap where the addition roof meets the original house wall. That gap opens because the ledger board is pulling away or the flashing was never installed correctly. In a heavy Hill Country thunderstorm, water gets driven into that gap and ends up inside your wall cavity.
- Doors inside the addition that stick in summer and swing freely in winter. This is the classic Texas symptom of a slab that’s heaving with moisture. It means the addition was poured without proper soil prep or without enough rebar to keep the slab rigid.
- Musty smell that doesn’t go away, especially near the baseboards. That’s moisture wicking up through the slab or behind the wall. In an ActiveYards garage conversion, it’s usually because nobody installed a moisture barrier between the old concrete slab and the new subfloor.
- A roofline that dips visibly when you sight down it from the street. That’s not cosmetic. A sagging ridge or a sway-backed eave means the roof rafters or the supporting beam have lost load capacity. In the worst cases we’ve seen in neighborhoods like Alamo Heights and Terrell Hills, the ridge had dropped nearly two inches over a 16-foot run.

AfterReplacement Cost & What’s Included
For a partial rebuild or structural re-tie of an existing ActiveYards addition in San Antonio, you’re looking at $45,000 – $130,000 depending on how much of the original framing, foundation, and roofline has to be redone. A smaller scope, like re-flashing the roof tie and replacing water-damaged sheathing, lands at the lower end. A full gut-and-rebuild of a failed addition, with new framing, new insulation, new drywall, and new electrical, lands higher. Here’s how the work typically breaks down:
- Structural assessment and engineering: $1,500 – $4,000, depending on whether we need a licensed engineer to sign off on load calculations.
- Foundation repair or stabilization: $5,000 – $20,000, depending on how many piers or how much slab work the soil conditions demand.
- Framing repair or partial rebuild: $8,000 – $35,000, driven by how much original lumber has to come out.
- Roof re-tie, flashing, and shingle or metal work: $6,000 – $25,000, depending on roof pitch and existing material.
- Insulation, drywall, trim, paint: $7,000 – $20,000 for a typical addition footprint.
- Electrical and HVAC tie-in updates: $4,000 – $15,000, depending on panel capacity and duct length.
Every estimate is a written line-item price, not a ballpark that changes once we open the walls. If we find hidden damage mid-project, you get a photo, a written change order, and your approval before any additional work starts. No surprises at the invoice. Our work on every addition or ADU repair carries the 365-Day Done Right Promise in writing: if it’s not done right, we make it right. That’s not a verbal assurance; it’s on the paperwork.
DIY or Call Us?
You can safely inspect your ActiveYards addition without touching a single tool. Take photos of the cracks, the roof gap, the sticking doors. Note whether the symptoms change with the weather. That documentation helps us give you a faster, more accurate diagnosis over the phone. What you should not do is start pulling drywall, jacking up beams, or injecting crack filler into a slab that’s actively moving. Structural work on an addition or ADU is dangerous when done wrong. A jack placed incorrectly can shift the entire load path and crack the main house’s framing. A beam that’s been supporting your roof for 15 years is under real tension, and cutting into it without understanding the load is how people get hurt and how buildings collapse. If the failure involves the roof tie, the ledger board, or any load-bearing wall, leave it alone and call a professional. Our team has been doing structural repair work across San Antonio for years, and Luca Romano still walks every finished job himself before we hand it back to you. Call (432) 547-6806 and send us the photos. We’ll tell you honestly if it’s a repair or a rebuild, and what it’ll cost.
FAQs
A properly built ActiveYards addition in San Antonio should last 40 – 50 years before any major structural work, but the original slab and roof tie typically need attention at the 15 – 20 year mark because of our clay soil movement and UV exposure. If yours is failing at year 10, the original install likely cut corners. Call (432) 547-6806 and we’ll tell you what you’re actually looking at.
Yes, in most cases we can re-tie the roof, stabilize the foundation, and repair the framing without a full teardown, which is typically 40 – 60% less expensive than rebuilding from scratch. The only time replacement makes more sense is when rot or termite damage has compromised more than half the structural lumber. A free estimate will tell you which side of that line you’re on.
Most ActiveYards addition repairs take 2 – 5 weeks from the first day on site, depending on scope; a full structural re-tie with interior refinishing runs 4 – 8 weeks. Weather delays are real during spring storm season, but we give you a written schedule and photo updates at every step through The Relay Visibility Guarantee. Call (432) 547-6806 for a realistic timeline on your specific project.
We stock commonly needed structural hardware for ActiveYards additions: hurricane ties, ledger bolts, flashing, and insulation rated for our Texas climate, along with aftermarket equivalents when ActiveYards OEM parts are discontinued. For anything uncommon, we order it before the job starts and confirm the spec with you. We also work regularly with material suppliers for KraftMaid, Cambria, and Silestone finishes if your repair includes new surfaces. Estimates are free, so call us for the right answer on parts availability.
