AfterFast, Reliable Home Additions & ADU Across Jersey Village
A home addition in Jersey Village typically runs $45,000 to $130,000, while a full detached ADU lands between $90,000 and $220,000 depending on size, foundation work, and flood compliance requirements. We know those are real numbers because we’ve been building here long enough to understand what Jersey Village’s flood history, clay soils, and the city’s independent building department actually do to a project budget. Call (877) 610-1318 and we’ll give you a written line-item estimate, not a ballpark guess.
If you live near Jersey Drive, along Village Green, or back behind the golf course off Rio Grande, you already know what we mean. Many of the ranch homes in the 77064 zip code sit on original slab foundations that have been there since the 1950s and 60s. Adding square footage to those homes is not a cut-and-paste job. It takes someone who knows what the city inspector here will flag, what the Harris County Flood Control District wants to see before you touch a foundation, and what your lot’s elevation actually allows you to build. That’s where we come in.
Why Barrett & Sons Construction Is Jersey Village’s Preferred Home Additions & ADU Company
We’re owner-operated. Tom Barrett started this company in 1998, and his sons run the crews. When you call, you get a live person on the phone at (877) 610-1318. When work starts, Tom or one of his sons is on-site most days. This is not a franchise handing your project to strangers in a van.
Jersey Village has its own municipal building department, separate from the City of Houston. We’ve pulled permits there enough times to know what the local inspectors look for, and we’ve seen contractors get turned away at inspection because they filed Houston paperwork assuming the enclave worked like everywhere else around it. Our Home Additions & ADU team coordinates with the Jersey Village permit office directly. Every eligible job gets permits pulled and inspections signed. If something needs a change, you get a written change order before we touch a nail – never a surprise invoice at the end.
Tom publishes his name, address, and license number. Ask anyone on your street – or look it up yourself. We’ve spent 29 years in this region, and the reason that matters is simple: we live close enough that if something isn’t right, we want to know about it. That’s the whole idea behind our 90-Day Done Right Promise. It’s written on every contract. If it’s not done right, one call brings Tom back to make it right.
Our Home Additions & ADU Services in Jersey Village
ADU Design & Permitting
Because much of Jersey Village sits inside the flood pool of the Addicks Reservoir, an ADU here often triggers FEMA elevation questions that a garage conversion in Cypress doesn’t. We handle the design, the permit paperwork, the elevation review, and the coordination with local inspectors. You get a plan that actually passes the first time, not a headache that lives in your inbox for six months.
Garage Conversion ADU
Converting a garage in Jersey Village usually costs $30,000 to $80,000, depending on whether the existing slab can stay or needs to come up. Homes built in the 1960s and early 70s around here often sit at low finished-floor elevations, and a garage conversion occasionally exposes slab issues that a normal addition wouldn’t. We scope it honestly before you spend a dollar, with every allowance in writing.
New Detached ADU
A new detached ADU in Jersey Village runs $90,000 to $220,000, with most of that range driven by foundation type. Elevated pier foundations, flood vents, and breakaway lower enclosures are common post-Harvey requirements here, and they’re the right way to build on Beaumont Clay soils that swell and shrink through Houston’s wet-dry cycles. We’ve built these before, and we’ll tell you straight what your lot’s elevation means for your budget.
Junior ADU & Interior Conversion
A junior ADU - converting an interior space like a large bedroom, a bonus room, or an attached sunroom into a self-contained living unit - is often the most cost-effective option in Jersey Village because it works within the existing footprint and rarely requires the same foundation or flood-elevation work that Windows & Doors in Jersey Village projects sometimes trigger. Prices vary widely depending on plumbing and kitchenette scope, but we’ll scope it line by line before you commit.

Trusted Brands We Service in Jersey Village
We build with materials you can look up. For ADU hardscape and patio tie-ins, we install Belgard and Techo-Bloc pavers. For the structure itself, we source from manufacturers whose warranties you can actually read. Because we’re working in Jersey Village regularly - from Jersey Village Roofing to full builds - we keep local suppliers on call and know which vendors stock the right materials for flood-resilient builds, so we aren’t waiting two weeks on a special order for something a supplier ten minutes away has on hand.
Common Home Additions & ADU Problems We See in Jersey Village Homes
- Low finished-floor elevations on original slabs. Many 1950s-to-1970s ranch homes here sit lower than current flood standards, and an addition that ties into the existing slab can drag the whole project into flood compliance review. We plan for that from day one, not halfway through framing.
- Expansive clay soil under older foundations. Beaumont Clay in this area moves more than most people realize, and a new addition anchored to a shifting slab will crack at the seam. We evaluate soil conditions and design the connection accordingly.
- Walking in with the wrong permits. Jersey Village runs its own building department independent of Houston. Contractors who don’t work here regularly file the wrong paperwork and get stopped at inspection. We file through the Jersey Village office directly.
- Mixing old framing with new elevated foundations. Post-Harvey rebuilds here often leave a home’s original wood framing sitting on a new pier foundation. Adding onto that condition requires real care with load paths and connections. We’ve done enough of it to know where the problems hide.
Pricing for Home Additions & ADU in Jersey Village, TX
A straight room addition in Jersey Village typically falls between $45,000 and $130,000. A garage conversion lands at $30,000 to $80,000. A new detached ADU runs $90,000 to $220,000. The biggest variables are foundation type, flood-elevation requirements, and how much of the existing structure you’re tying into. A second-story addition also runs in the $45,000 to $130,000 range, but can climb higher if your original framing needs reinforcement.

FAQs - Home Additions & ADU in Jersey Village
Most Jersey Village additions start within a few weeks of permit approval. Permit review speed depends on the city’s schedule and whether flood elevation review is required. Call (877) 610-1318 and we’ll tell you what the current timeline looks like for your specific address.
Yes. We pull permits through the Jersey Village building department, coordinate inspections, and handle any Harris County Flood Control District or FEMA elevation paperwork your project requires. The permit inspector works for you, not for us – that’s why we like having him on the job.
Sometimes, yes. Jersey Village’s flood history and its independent building department add compliance steps that many surrounding Houston neighborhoods don’t face. Foundation elevation, flood vents, and local permit review can add $5,000 to $20,000 to a project depending on the scope. We’ll show you exactly where those dollars go in writing before you sign anything.
Every completed job comes with our written 90-Day Done Right Promise. If something isn’t right, Tom comes back and makes it right. One call to (877) 610-1318 is all it takes.
In most cases, yes – but the project has to meet current elevation and floodplain standards. Many Jersey Village homeowners rebuilding after Harvey have done exactly this, often with elevated foundations and flood vents. We’ll review your lot’s elevation certificate and tell you what’s realistic before you invest in design work.
