AfterFast, Reliable Home Additions & ADU Across West Gate
If you’re thinking about a home addition or ADU in West Gate, the honest answer is that most projects here run $45,000 to $130,000, and the permit path runs through Palm Beach County, not a city hall. That county process changes timelines, inspection scheduling, and which code upgrades get triggered the moment a wall comes open. Tom Barrett and his sons have managed that exact path on West Gate’s aging CBS homes for years, and we build the county’s slower inspection turnaround into our schedules instead of pretending it doesn’t exist. Call (877) 610-1318 for a free estimate, and we’ll walk your specific street and your specific house before we quote anything.
Why Barrett & Sons Construction Is West Gate’s Preferred Home Additions & ADU Company
We’ve been doing Home Additions & ADU work in West Gate long enough to know that a 1960s concrete block home near a flat roof doesn’t open up the same way a new build in Royal Palm does. Ask anyone on your street, or look up our license number yourself. Tom Barrett publishes his name, his address, and his license number on every contract, because the last contractor most West Gate customers used told them permits were optional. Ours aren’t.
When you call us, a live person answers the phone twenty-four hours a day, not a voicemail box and not an out-of-state call center. We’re not a franchise dispatching strangers. Tom’s sons run the crews that work in West Gate, and they carry background checks and uniforms that say Barrett & Sons on them. Every scope, every allowance, every price change arrives as a written change order before work happens. Not after.
West Gate homeowners between fifty and seventy have told us the same story more times than we can count. A national outfit quoted one price over the phone, then handed them a different bill at the door. That’s exactly why we write everything down before a single nail moves. We’d rather lose a bid than surprise you mid-project.
Our Home Additions & ADU Services in West Gate
ADU Design & Permitting
Because West Gate sits in unincorporated Palm Beach County, every ADU permit goes through the county’s Building Division, not a municipal office. That means the design has to account for the county’s review timeline, which runs slower than most people expect. We handle the drawings, the county submittal, and the back-and-forth with inspectors, so you’re not chasing a permit status line. We also price the permit fees and code upgrades into the initial contract with written allowances, not vague promises.
Garage Conversion ADU
A garage conversion in West Gate typically runs $30,000 to $80,000, depending on whether the existing slab can be reused and how much of the old wiring and roof decking needs to come up to current Florida Building Code. Most West Gate garages were poured in the 1950s through 1970s, and many slabs lack the vapor barrier and reinforcing steel a permitted living space requires. We bring in a county-required inspection before we pour any topping slab or frame any interior wall.
New Detached ADU
A detached ADU in West Gate is a bigger investment, $90,000 to $220,000, and the single biggest variable is site prep. West Gate’s June-through-October wet season saturates fill soils, and that slows slab and footer pours. We schedule foundation work around the weather window and write soil condition allowances into the contract so a wet week doesn’t turn into a surprise bill. The county’s High-Velocity Hurricane Zone requirements also mean every new structure gets engineered for 160+ mph wind loads. That’s not optional, and it shouldn’t be.
Junior ADU & Interior Conversion
A junior ADU or interior conversion is often the smartest move in West Gate, especially when the existing floor plan already has a separate entrance or an underused den. These projects reuse the home’s existing roof and walls, which keeps the county’s structural review simpler, but they still trigger wind-load upgrades on any opening we enlarge or reconfigure. We walk the house before quoting, because what’s behind a 1960s CBS wall is rarely what the homeowner assumes.

Trusted Brands We Service in West Gate
We install windows and openings that hold up to Palm Beach County’s wind-load math. On West Gate projects we routinely spec PGT, CGI, and Simonton impact-rated windows and doors, because they meet the 160+ mph design pressures the county enforces. These are brands you can look up, not mystery products off a van. We order them sized for your exact rough openings and have them staged before demolition starts, so a West Gate project doesn’t sit open to the weather waiting on a window truck.
Common Home Additions & ADU Problems We See in West Gate Homes
- Pre-Andrew roof-to-wall connections. Most West Gate homes built before the 1990s lack hurricane straps and have roof decking nailed at pre-code fastening schedules. Any second-story addition or structural alteration triggers a code review that almost always requires a full tie-down retrofit before framing passes.
- County inspection delays get mistaken for contractor delays. A framing inspection in West Gate can run several days behind a West Palm Beach municipal schedule, simply because county inspectors cover a sprawling multi-community territory. Contractors who don’t pad their schedule leave homeowners living in a gutted room longer than promised.
- Hidden wiring and waterproofing failures behind CBS walls. The 1950s through 1970s block homes of West Gate often hide original cloth-wrapped wiring and failed water barriers behind interior finishes. Once a wall is open, the county inspector requires the wiring brought to current code, and that’s a cost that should be written in as an allowance, not a mid-project surprise.
- Flat and low-pitched roof conditions. Many West Gate homes have flat or low-slope roofs that were never designed for a second story’s weight. Before we cut any roof opening, we verify load-bearing capacity, and the numbers often require engineered upgrades that get priced and approved in writing before the saw comes out.
How We Handle Surprises When We Open a West Gate Home
On a 1960s CBS home near a West Gate flat roof, our crew opened the wall for a second-story addition and found original roof decking fastened with pre-Andrew nail schedules and no hurricane straps anywhere. We stopped the scope of work right there. No guesswork, no “we’ll figure it out later.” We priced the FBC-mandated tie-down retrofit and impact-rated openings as a written change order, got the county inspector’s sign-off, and then moved forward with rough-in. That’s the West Gate way we work on every project. An allowance that isn’t on paper is a surprise waiting for a date, and we don’t do surprises.
This is the single biggest reason a remodeling quote moves once walls are open. Older West Gate homes hide outdated wiring, undersized framing, failed waterproofing, and code deficiencies that a permit inspection will flag the moment they’re visible. Our process is simple: inspection first, allowances written into the contract before demolition starts, and any surprise priced and approved in writing before we touch it. Then Tom Barrett and his sons stand behind the finished work with the written 90-Day Done Right Promise.

FAQs - Home Additions & ADU in West Gate
West Gate is unincorporated, so its permits run through Palm Beach County’s Building Division rather than a city building department. County inspectors cover a sprawling multi-community territory, so a framing or rough-in inspection in West Gate can realistically take several extra days compared to a municipality with its own on-call inspectors. Experienced crews pad their schedules accordingly. Call (877) 610-1318 and we’ll show you the exact county submission timeline for your project.
Expect wind-load and roof-to-wall connection upgrades. Most West Gate homes built in that era lack hurricane straps, have roof decking nailed at pre-Andrew fastening schedules, and feature original wiring that doesn’t meet current Florida Building Code. Once a permit inspection sees those conditions, retrofitting becomes mandatory, not optional. We write allowances for exactly these discoveries into the contract upfront. Call (877) 610-1318 for a free estimate that includes those allowances.
We schedule foundation pours around the weather window, and we write soil condition allowances into the contract. West Gate’s June-through-October wet season brings near-daily afternoon thunderstorms, and saturated fill soils complicate slab and footer pours for any detached ADU. If a pour gets delayed, the delay is already accounted for in your schedule and your pricing. Call (877) 610-1318 to walk your lot and talk pour strategy.
A garage conversion is a full county permit job in West Gate, not a minor alteration. The moment interior living space replaces a garage, the county requires the slab, the electrical, the openings, and the roof structure to meet current code. That’s not a gray area, and any contractor who tells you otherwise is setting you up for a failed inspection. Call (877) 610-1318 and we’ll handle the county paperwork properly from the first submittal.
Budget $90,000 to $220,000 for a detached ADU in West Gate. The range is wide because site prep, foundation work, wind-load engineering, and the condition of the existing lot vary dramatically from street to street. A flat, well-drained lot with easy access costs less than a saturated, tight-access lot during the wet season. The only way to know your number is a walkthrough and a written line-item quote. Call (877) 610-1318 and we’ll schedule yours free.
