Fast, Reliable Home Additions & ADU Across Weston
A home addition or ADU in Weston runs roughly $45,000-$130,000 for a room addition and $90,000-$220,000 for a detached ADU, and the single factor that surprises most Weston homeowners isn’t construction cost, it’s the approval pipeline. Neighbors in Sector 7, The Ridges, and Windmill Reserve call us because they’re tired of contractors who quote a price but can’t explain why their HOA’s Architectural Review Committee will add three to six weeks before the first building permit gets pulled. We know the drill here. Tom Barrett and his sons have worked the dual-approval path in Weston’s villages long enough to schedule for it, file for it, and keep your project moving while others sit stalled. Call (877) 610-1318 for a free estimate and a straight answer on what your HOA will actually sign off on.
Key Takeaways:

Why Barrett & Sons Construction Is Weston’s Preferred Home Additions & ADU Company
We’re an owner-operated construction company, not a franchise sending strangers from somewhere else. Tom Barrett puts his name, address, and license number on every Weston bid, and his sons run the crews that show up on your street. That matters when your addition has to survive an HOA review board, a county plan reviewer, and a South Florida rainy season all in the same calendar year.
Our Weston customers tend to find us after a previous contractor got through county permitting and then watched the project freeze because no one had filed with the HOA Architectural Review Committee first. We file both. We track both. And when the ARC comes back with a color-matching comment on your barrel tile or a question about impact door trim, we handle it in writing, not by disappearing from the job site.
Weston’s housing stock is almost entirely concrete block, post-Hurricane Andrew construction, sailing past the 25-to-30-year mark all at once. That means we see the same failure points in home additions here time and again, and we plan for them before the first wall goes up. A live person answers our phone around the clock, not a voicemail box, and if you’ve ever tried reaching a national outfit at 7 p.m. to ask why your addition permit is stuck, you’ll know why that matters.
Our Home Additions & ADU Services in Weston
We handle the full range of home addition and ADU work across Weston, from first submittal packet to final inspection. Here’s what Weston homeowners call us for most often.
ADU Design & Permitting
This is where Weston separates the careful contractors from the ones who eventually stop answering calls. We prepare the full submittal packet for both the HOA’s Architectural Review Committee and Broward County. That includes floor plans, elevation drawings, material specifications, and most critically, a color and finish schedule that matches your existing stucco, barrel tile, and trim. We file with the ARC first because that’s the approval that eats the most time in Weston. Once they sign, we move to county permitting and start ordering materials so your project isn’t waiting on framing lumber.

Garage Conversion ADU
Converting a two-car garage into an ADU is one of the smartest moves in Weston because the structure already exists, the roof line stays close to the original massing, and most villages in Weston allow it by right with ARC review. Expect the committee to care about door style, window placement, and whether your new interior square footage changes the home’s storm-water footprint. We recently converted a two-car garage in Sector 7 into a junior ADU for an aging parent. The ARC rejected the first submittal because the proposed impact-rated door didn’t match the barrel-tile trim color of the main home. Our team resubmitted with a color-matched Cambria countertop and KraftMaid cabinetry allowance, and we had final inspection sign-off in 14 weeks, including the HOA’s final drive-by check.

New Detached ADU
A detached ADU in Weston is a bigger lift because you’re building new foundation on a site with a high water table and peat pockets near the Everglades fringe. We engineer for that from step one: dewatering as needed, engineered fill under the slab, and drainage designed for Weston’s June-to-October rain cycle. Detached ADUs also trigger stricter ARC scrutiny on roofline, setback, and elevation matching. Give us the village and lot dimensions and we’ll tell you straight what’s likely to pass.

Junior ADU & Interior Conversion
A junior ADU works well in Weston’s larger single-family homes because you can convert existing interior space, a bonus room, a large den, or an interior section of the garage, without adding roof area or runnning afoul of setback rules. Interior conversions still need county permitting for electrical, plumbing, and egress, but they tend to sail through ARC review with fewer material comment cycles than exterior-facing work. If your HOA is a known stickler about outward appearance, this is often the path of least resistance.

Trusted Brands We Service in Weston
We carry premium-brand depth across every trade we touch, and that extends to the brands Weston homeowners actually ask us about when they walk the showroom. We’re a GAF roofing and accessory installer, and we routinely combine Andersen windows and Marvin doors with addition scopes that need to meet Florida’s 140 mph design wind loads. For wet areas inside a new ADU or addition, we install Schluter waterproofing systems under tile because South Florida humidity and a high water table leave no room for a shortcut. You can look up any of these names before you sign, and we’d rather you do exactly that.
Common Home Additions & ADU Problems We See in Weston Homes
- HOA approval skipped entirely. A county permit doesn’t mean the village ARC has blessed the scope. We see projects hit with stop-work orders mid-draw schedule because a contractor went straight to Broward County and ignored the Architectural Review Committee. In Weston, the ARC can halt a job over a stucco color mismatch.
- Slab foundations cut without dewatering. Weston sits at the western edge of Broward County next to the Everglades, and the water table is high. Pouring a slab without engineered fill or dewatering leads to subfloor warping and cracked tile within two rainy seasons.
- Second-story additions that trigger re-engineering. Florida’s wind code requires 140 mph design wind loads in this area. If the first set of plans doesn’t account for shear panels and load-bearing wall reinforcement, the county plan review kicks it back and you pay for re-engineering before framing starts.
- Tile and trim mismatches on the ARC submittal. The review committee in villages like Sector 7 and The Ridges compares your proposed materials to the main home’s existing barrel tile, stucco, and trim. A submittal with a generic material schedule is usually the first rejection, and every resubmission adds two to three weeks.
Pricing for Home Additions & ADU in Weston, FL
Here’s what we quote on Weston projects, in straight numbers. These ranges reflect the dual-approval environment, the higher engineering requirements for 140 mph wind loads, and the high-water-table foundation work that Weston lots commonly require.
| Project Type | Weston Price Range |
|---|---|
| Home Addition | $45,000-$130,000 |
| ADU Construction | $90,000-$220,000 |
| Garage Conversion | $30,000-$80,000 |
What moves the number? For a room addition, it’s mostly size, foundation complexity, and whether you’re tying into the roof or building new. For a detached ADU, it’s who utilities run from, what the site prep requires, and how much ARC-required architectural detailing you need. Every scope, allowance, and change order arrives in writing before work proceeds, because an allowance that isn’t on paper is a surprise waiting for a date. Call (877) 610-1318 to schedule a free estimate and we’ll walk your lot with you, no change orders hidden in the truck.

FAQs - Home Additions & ADU in Weston
Yes, and this is the single biggest tripwire in Weston. A Broward County permit alone will not get legal work started in any of Weston’s HOA-governed villages. The ARC reviews exterior changes, material choices, and even some interior egress details separately from the county. Approvals are dual. Plan for both. Call (877) 610-1318 and we’ll file them in the right order.
Typically three to six weeks, and more if the first submittal comes back with comments. That’s before the county even starts reviewing plans. We build this window into every Weston schedule from day one, so your crew isn’t standing around waiting on a committee. If you’d like an exact timeline for your village, call us for a free estimate.
Often yes, but it comes down to roof structure, foundation strength, and whether the existing patio slab was poured as a living-space slab or an exterior slab. Sector 7’s ARC will want to see that the new room’s roofline and stucco finish match the main structure. We’ve done this exact conversion and can tell you whether your patio is a good candidate after one site visit.
Changes to roofline height, exterior material specs, window sizing or type, and any deviation from the color and finish schedule in the original submittal. The ARC compares what’s drawn to what’s installed, and a mismatched tile profile can flag a resubmission mid-build. That’s why we lock materials before we submit, not after we order.
Some Weston villages allow detached ADUs by right; others restrict them to specific lot sizes or setback configurations. The correct answer depends on your exact village and lot dimensions. We check that before we draw anything, and we’ll tell you honestly if your street is one where the ARC has historically approved them. Call (877) 610-1318 for a straight read on your lot.
