Home Additions in San Antonio
Second stories, room additions, in-law suites, and backyard ADUs — designed to feel like they were always part of your home. Built to match your existing structure exactly.
An addition that looks like it was always there, not something that was bolted on after the fact
Looking to build out instead of move? Home additions allow you to gain living space without leaving your neighborhood, school district, or HOA. We specialize in second stories, room additions, in-law suites, and backyard ADUs that match your existing home from the street… and finishings that blend seamlessly with your original construction.
Matching the look of an existing structure isn’t easy. Rooflines, siding and window proportions, interior finishes, and design flow need to match up perfectly. Everything you build also changes the load paths of your existing home. From our structural engineers to permitting in the City of San Antonio to sewer and water extensions, we handle it all.
Services We Offer
No matter the size of what we're adding, the process is the same: thorough, permitted, and structurally sound.
Adding space is complex — here's how we keep it clear
Additions involve your existing structure, city permits, and a tight coordination of trades. Our process keeps all of it organized so you don't have to.

Why Choose Us For Your Home Addition?
Additions Designed to Match
There’s nothing worse than a plainly-built addition. We’ll design a home extension that flows with your existing home, both inside and out. Don’t believe us? Check out our gallery. We’ve been sourcing matching materials and brick since before our first customer walked through the door.
Licensed Structural Engineers
Our engineers check every addition for foundation integrity before we even begin designing. Every room you build changes your load paths and connect points. We don’t make assumptions or cut corners.
Accessory Dwelling Unit Advisement
State law changed across Texas in recent years (SB 673), but San Antonio has gone one further. Lot setbacks, utility extensions, and even mandatory owner occupancy are among our ADU rules. Let us help you understand how San Antonio building codes impact your ADU plans.
No Permitting Hassles
Yep. You still need one. But we file it for you, handle every inspection, and coordinate those inspections into your schedule. Permit approval can take 3–6 weeks from the time we turn it in. Allowances are built into your schedule from day one.

Things people ask us before they call

Yes, most likely. San Antonio has specific restrictions when it comes to ADUs. Size, setbacks, and HOAs can prohibit you from adding an ADU. We’ll walk your property and let you know at our free consultation.
Any addition that will put more weight onto your existing foundation will be reviewed by our engineers. If reinforcement is needed, we’ll know before we design. Don’t worry… we’ll let you know the pricing ahead of time!
Good question. For homes built in the last ten years, we already have a lot of it in stock. We’ve spent years developing relationships with local material suppliers. Several specialize in hard-to-find brick or siding materials. As for the one-of-a-kind homes (we look at a lot of mid-century modern houses), we source reclaimed brick that matches your home.
Yes! ADUs on owner-occupied lots can be rented in the great state of Texas. San Antonio does not prohibit short-term rentals of ADUs in most residential zones. HOAs will have their own rules you’ll need to follow, but we can design with those rules in mind.
Between $180 and $280 per square foot on average. This depends on what you’re building and how finishes come into play. Independent Free-Standing Units (read: backyard ADUs) start at $120k for a basic studio ADU. Finished two-bedroom ADUs start at around $280k. Again, these prices are loose ranges. Once we understand what you want, we can give you an accurate fixed price to work with.
3–6 weeks for San Antonio permitting approval. Again, we file this for you and build it into your schedule.
