AfterFast, Reliable Home Additions & ADU Across Ingleside
A home addition in Ingleside typically costs $45,000 to $130,000, while a detached ADU runs $90,000 to $220,000 depending on size, foundation work, and coastal wind-zone requirements. We’ve built additions and ADUs across Ingleside for years, and we know what the salt air does to framing hardware and what the city expects on permit drawings before a single form gets poured. If you’re weighing a garage conversion, a second story, or a standalone ADU on your lot, call us at (877) 610-1318 and we’ll walk you through what’s realistic for your property.
Why Barrett & Sons Construction Is Ingleside’s Preferred Home Additions & ADU Company
We’re not a franchise that sends a rotating cast of strangers to your door. Barrett & Sons is owner-operated, founded in 1998, and Tom Barrett’s sons run the crews that show up on Ingleside jobsites. When you call, a live person answers, and the name on the contract is the same name on the truck. That matters in a town like Ingleside, where half the people you meet have been burned by a company that quoted one number on the phone and handed them a different invoice at the end.
Homeowners here tell us the same story again and again: a national outfit quoted a low number, started the job, then hit them with change orders that never showed up on paper. We handle it differently. Every scope, every allowance, every price change arrives as a written change order before work happens. The permit inspector works for you, not for me, and we pull permits on every eligible job. When the inspection passes, you get the signed record. When it doesn’t, we fix it before we call it done.
We also know the specific conditions that make Home Additions & ADU work different in Ingleside than they do twenty miles inland. Salt spray off Corpus Christi Bay eats exposed fasteners. High-wind design rules aren’t a suggestion here. And houses built during the Naval Station years often hide surprises behind the drywall. We plan for that from the first site visit, not after the saws start.
Every job we complete comes with our 90-Day Done Right Promise, written on the contract. If something isn’t right, one call brings Tom back. You can look up his name, his address, and his license number before you sign anything. We publish it because we want you to check.
Our Home Additions & ADU Services in Ingleside
Most Ingleside homeowners come to us with one of a handful of goals: add a bedroom for aging parents, build a rental unit to offset the mortgage, or convert a garage that’s been sitting half-finished since the Naval Station days. Here’s how we handle the most common requests.
ADU Design & Permitting
Building an ADU in Ingleside means navigating San Patricio County zoning, city setback rules, and wind-load requirements that inland builders never think about. We handle the drawings, the permit package, and the inspections, so you’re not making five trips to the county office. A typical permitted ADU project in Ingleside runs $90,000 to $220,000 complete, from foundation to final inspection.
Garage Conversion ADU
Ingleside has a lot of attached and detached garages on slabs built between the 1960s and 1990s, and many of them are structurally sound but underused. Converting one to a livable ADU usually costs $30,000 to $80,000 depending on whether we’re adding plumbing, upgrading the electrical panel, and reinforcing the slab. In ZIP code 78362, we regularly see garage floors that need leveling before any framing starts, simply because the original pour didn’t account for fifty years of coastal moisture.
New Detached ADU
A new detached ADU gives you a clean slate: proper insulation, hurricane-rated windows, and a roof system designed for South Texas wind. Detached ADU construction in Ingleside typically runs $90,000 to $220,000 depending on square footage, foundation type, and finish level. We build them with galvanized and stainless connectors throughout, because anything less corrodes faster here than homeowners expect.
Junior ADU & Interior Conversion
If you have an oversized primary bedroom, a formal dining room that never gets used, or a den that’s been collecting boxes, a junior ADU or interior conversion can add a private living space without touching the footprint of your home. These projects in Ingleside typically fall between $45,000 and $100,000 when they include a kitchenette and a private entrance. We’ve done several interior conversions in homes near the old Naval Station footprint, where interior walls sometimes hide reinforced framing that requires extra planning to modify safely.
We also handle room additions, second story additions, and sunrooms, and our Kitchen Remodeling in Ingleside team can expand your existing kitchen while we’re adding square footage. If the addition touches a bathroom, our Bathroom Remodeling in Ingleside crew steps in so you’re not juggling two contractors.

Trusted Brands We Service in Ingleside
When we install windows, doors, or shower systems on an Ingleside addition, we use materials you can look up by name. We regularly specify GAF for roofing, Schluter for waterproofing in wet areas, and Grohe or Sterling fixtures when the plan calls for them. Sourcing premium-brand materials means fewer callbacks and a longer service life, and in a coastal environment like Ingleside, that’s not a luxury. It’s the only way to build something that still looks right ten years from now.
Common Home Additions & ADU Problems We See in Ingleside Homes
- Salt-corroded framing connectors: Persistent onshore winds off Corpus Christi Bay drive salt spray through every gap in the building envelope. We routinely find rusted anchor bolts, corroded hangers, and degraded flashing in additions and garages that were built with standard hardware instead of galvanized or stainless. Any addition we build in Ingleside gets corrosion-rated connectors from day one.
- Slab issues from deferred maintenance: The 2010 BRAC closure of Naval Station Ingleside hit the local economy hard, and a lot of homeowners deferred repairs for years. When we open up a slab for a room addition or ADU conversion, we often find moisture intrusion, cracking, or settling that needs addressing before new framing goes up.
- Military-spec surprises near the old Naval Station: Homes and structures built near the former Naval Station Ingleside footprint sometimes sit on reinforced concrete pads or contain oversized utility runs that were built to federal standards. Demolition and foundation bids can jump when crews hit concrete engineered for naval operations, which is why we always walk the site and check existing plans before quoting.
- High-wind design gaps: Hurricanes aren’t theoretical in San Patricio County. The outer bands of Hurricane Harvey caused flooding and wind damage across Ingleside in 2017, and any addition or ADU has to meet current wind-zone requirements. We build for that code from the start, including roof tie-downs, impact-rated openings, and proper sheathing nailing patterns.
Pricing for Home Additions & ADU in Ingleside, TX
Home additions in Ingleside run $45,000 to $130,000. ADU construction, whether detached or a full conversion, runs $90,000 to $220,000. Garage conversion ADUs land between $30,000 and $80,000. These aren’t phone-quote numbers. They reflect what we actually see on Ingleside jobsites after accounting for slab work, coastal wind-zone detailing, and the materials we won’t compromise on.
What moves the number? Square footage, foundation condition, whether the existing electrical panel can handle the added load, and how far the site sits from the bay. Salt exposure dictates fastener and flashing upgrades, and homes near the old Naval Station footprint can carry demolition premiums. We give you a line-item written estimate before you commit, and a written change order before any scope change touches the job. No surprises at the end. Call (877) 610-1318 for a free estimate.

FAQs - Home Additions & ADU in Ingleside
A typical home addition in Ingleside runs $45,000 to $130,000, with detached ADUs ranging from $90,000 to $220,000 and garage conversions from $30,000 to $80,000.

Yes. We cover the entire 78362 ZIP code and surrounding areas, including neighborhoods on both sides of Highway 361 and all the way down to the bayfront. Scheduling is coordinated through our DFW office, but the crews working in Ingleside are local to the Coastal Bend and know the building inspector, the supply houses, and the roads from Aransas Pass to Rockport.
Not unless the scope changes. Every price adjustment comes as a written change order before any new work begins. If we open a wall and find something unexpected, like reinforced concrete or salt-damaged framing near the old Naval Station footprint, we’ll show you what we found, put the new number on paper, and wait for your signature before we proceed. You won’t get a surprise invoice at the end.
A garage conversion ADU typically takes 8 to 12 weeks. A new detached ADU runs 4 to 6 months, and a full room addition or second story can range from 3 to 8 months depending on scope and weather. Coastal wind conditions sometimes delay crane and roofing work, and we plan our schedules around that rather than pretending it doesn’t exist.
Every job carries our 90-Day Done Right Promise, written on the contract. If something isn’t done right, Tom Barrett comes back and makes it right, one call. We also pass through manufacturer warranties on the materials we install, and we pull permits and pass inspections on every eligible job so the work is on record with the city. If you’re comparing contractors, call (877) 610-1318 and ask us anything. Estimates are free.
