AfterFast, Reliable Home Additions & ADU Across Bacliff
A home addition or ADU in Bacliff typically runs $45,000-$130,000 for a room addition, and $90,000-$220,000 for a new detached ADU. For roofing on these projects, see our Bacliff Roofing services. Most projects take 4-9 months from the first plans to the final inspection, depending on whether we’re working with an existing slab or building up on pilings. If you live in the 77518 zip and you’re wondering what it’ll actually cost and who can get it done right, call Barrett & Sons at (877) 610-1318. Tom Barrett has been running crews for over 29 years, and his sons are on-site most days.
Why Barrett & Sons Construction Is Bacliff’s Preferred Home Additions & ADU Company
Bacliff isn’t League City or Webster. It’s unincorporated Galveston County, which means there’s no city hall to pull permits from. You work directly with the county, and the county inspector is going to look hard at your foundation elevation before any addition gets signed off. We know that. We’ve been through it enough times to know which questions the county asks and when they ask them.
Tom Barrett founded this company in 1998, and the name on the truck is the name you’ll see at the job site. His sons run the crews. Every scope, every allowance, every price change arrives as a written change order before work happens. If the county flags your slab-on-grade camp house and an elevation certificate suddenly becomes part of the project, you’ll see that on paper with a dollar figure attached, not discover it in the final invoice. One call brings Tom back if anything’s wrong. That’s the 90-Day Done Right Promise, and it’s written on every contract.
There’s also a real person answering the phone 24/7. Not a voicemail box, not an out-of-state call center. Call (877) 610-1318 and you’ll get a human who knows Bacliff.
Our Home Additions & ADU Services in Bacliff
We handle the full Home Additions & ADU range, from a single room addition to a full detached unit with its own utilities. Here’s what most Bacliff homeowners call us about.
ADU Design & Permitting
Permits for Home Additions & ADU in Bacliff go through Galveston County, not any municipal building department. That changes the paperwork, the inspection schedule, and sometimes the foundation plan. We handle drawings, county submittals, and the back-and-forth until the permit is in hand. No homeowner wants to sit on hold with the county clerk trying to figure out why their elevation certificate got kicked back. That’s our job.
Garage Conversion ADU
Garage conversions in Bacliff run $30,000-$80,000. The big variable is the existing slab. If the garage slab sits below the current Base Flood Elevation, the county may require a full elevation repair before we can close the permit, and that turns a straightforward conversion into a more involved project. We’ll tell you that in the first estimate, not after demo starts.
New Detached ADU
A new detached ADU in Bacliff runs $90,000-$220,000, and on Galveston Bay, that means building on pilings or a tall pier-and-beam foundation above the FEMA flood zone. There’s no elegant shortcut. The salt air also means we specify corrosion-resistant fasteners and connectors as standard, because the cheaper hardware will rust out years before the structure should need it.
Junior ADU & Interior Conversion
Interior conversions, like closing off part of a house into a self-contained suite with its own entrance, work well on Bacliff’s older post-Ike elevated homes. If the main structure is already compliant, the county’s focus is usually on egress, kitchenette wiring, and a separate exterior access. We’ve done enough of these to know where the inspector lingers.
And if your addition plan is really a full-scale renovation, we also handle Kitchen Remodeling in Bacliff and Bathroom Remodeling in Bacliff alongside the structural work.

Trusted Brands We Service in Bacliff
When we build a sunroom, an enclosed patio, or a second-story addition, we install Windows & Doors - Bacliff from Simonton, Ply Gem, and CGI. CGI’s impact-rated windows are genuinely relevant out here, given what a hurricane can do to a window on the open bay. These are brands you can look up, not white-label products off a van. We order direct and stage the materials before the crew starts cutting, which keeps a Bacliff project moving even when a supplier runs short.
Common Home Additions & ADU Problems We See in Bacliff Homes
- Slab-on-grade foundations flagged by the county. A lot of pre-Ike cottages and fishing camps still sit at-grade. Start an addition, and the county can require an elevation certificate that forces foundation rework before the project can close.
- Salt-driven corrosion on framing and connectors. The western shore of Galveston Bay puts persistent salt air against every exposed fastener. We see corroded metal connectors and sheathing nails on homes that are only 15-20 years old.
- Wind uplift loads on second-story additions. A second story changes the entire wind profile of the house. County inspectors focus on the tie-down path from the roof to the foundation, and retrofitting an older lower floor to match the new upper load often adds a line item the homeowner never expected.
- Patchwork housing stock with no uniform setbacks. Bacliff is a mix of modest wood-frame cottages and post-2008 elevated rebuilds. Property lines can be close, and county setback rules apply differently depending on whether the structure is already compliant or getting rebuilt from scratch.

FAQs - Home Additions & ADU in Bacliff
We can usually get to Bacliff within a few days for an estimate, and the county-side scheduling for permits and inspections is often the longer timeline. Call (877) 610-1318 to set up a walk-through. There’s no trip charge inside the county.
Yes. We pull all permits for Bacliff work directly through Galveston County, which is a different process than anything you’d do with a municipal building department. We handle the paperwork, the elevation requirements, and the inspection coordination so you don’t have to chase it yourself.
Because Bacliff sits at near-sea-level elevation on Galveston Bay, the county requires most new construction and major additions to meet FEMA Base Flood Elevation. If your existing structure was built before the post-Ike advisory maps, an addition can trigger the elevation review. We’ll flag that risk in the initial estimate.
Only if the scope changes in writing. Every allowance, every material substitution, every county-required fix arrives as a written change order with a dollar amount before the work proceeds. No surprise invoices at the end. Ask anyone on your street, or look up our license number yourself.
Yes. The 90-Day Done Right Promise is written on every Barrett & Sons contract, and it covers work done anywhere we operate, including Bacliff. If it’s not done right, Tom comes back and makes it right, one call.
