Garage & Attic Conversions in San Antonio
Turn unconditioned garage and attic space into comfortable, code-compliant living areas.
Common Conversions problems
What San Antonio homeowners tell us before they call
A garage or attic used only for storage
Unconditioned space with no insulation, no HVAC, and no egress isn't livable — but with the right work, it can be your most affordable way to add a bedroom or home office.
Conversions that fail code and don't appraise
Unpermitted square footage doesn't count toward your home's value at resale. Ceiling height, egress, proper HVAC, and electrical are code requirements that matter at inspection time.
The cost of digging a new foundation
An addition needs a new slab. A garage or attic conversion reuses the existing structure, making it the most cost-effective way to add legal, appraised living space.

Garage & Attic Conversions in San Antonio, the design-build way
Last updated: June 24, 2026
Converting a garage or attic is the most cost-effective way to add living space without a new foundation. We handle insulation, HVAC, egress, ceiling height, and electrical to meet code, manage the permits, and finish the space so it lives like the rest of your home.

- ✓ Garage-to-living-space conversions
- ✓ Attic conversions and bonus rooms
- ✓ Insulation, HVAC, and egress to code
- ✓ Permitting and inspections
- ✓ Parking-replacement compliance
- ✓ Ceiling-height and structural review
Garage and attic conversions, done to code
Converting unconditioned space is the most cost-effective way to add a bedroom, home office, gym, or in-law suite — because the foundation, walls, and roof are already there. But “cheaper than an addition” only works if the conversion meets code. Otherwise you’ve created unpermitted square footage that doesn’t appraise.
What a real conversion includes
- Structural review — is the existing structure sound enough to bear conditioned-space load?
- Insulation — walls, ceiling, and (for garages) the slab edge, properly air-sealed
- HVAC — usually a mini-split or extension of the existing system, sized to the new conditioned load
- Egress — proper window sizing if the space serves as a bedroom
- Ceiling height — minimum 7 feet for living space; attic conversions sometimes require structural changes to gain headroom
- Electrical — bringing the existing garage panel/circuits up to current code, GFCI as required
- Plumbing — if you’re adding a bath or kitchenette, full rough-in
- Finish — flooring, drywall, paint, trim, doors
Parking replacement is non-negotiable
If you convert a garage that’s counted as off-street parking, San Antonio code generally requires you to replace it. That means either an expanded driveway with proper setback, a carport, or another approved solution. We design this into the project so the permit clears.
What conversions usually become
The most common conversions we build:
- Garage → primary bedroom suite with private bath
- Garage → home office with built-in bookshelves
- Garage → media room or gym
- Attic → bonus room or playroom
- Attic → primary suite with dormer addition for headroom and light
Why homeowners pick us
Same process. Same crew. Same fixed price.
We meet code, not just cover drywall
A garage or attic converted without proper insulation, egress, or HVAC isn't legal living space — and won't appraise as one. We engineer the conversion to actually count.
Parking-replacement compliance
San Antonio code requires off-street parking. Garage conversions need a replacement parking plan. We design it into the project so the permit goes through.
Comfortable, not just enclosed
Properly insulating an attic or garage in San Antonio's climate is real work. We air-seal, insulate to current code, and size the HVAC for the new conditioned space.

What homeowners say
4.9 stars across 200+ Houzz reviews
50% of our projects come from direct referrals. Here's why.
"From the first design-center visit to the final walkthrough, we had one point of contact and one price that never moved. Our kitchen is unrecognizable in the best way."
"They removed a load-bearing wall and turned three cramped rooms into an open living space. The crew was the same faces every day for weeks — that mattered."
"Our walk-in shower is gorgeous and finally accessible for my mom. They handled the layout, plumbing, and waterproofing without us chasing anyone."
"We added an in-law suite and you genuinely cannot tell it wasn't part of the original house — the brick and roofline match perfectly."
"Transparent budgeting was the whole reason we picked them, and they delivered. No surprise change orders, no hidden fees."
