AfterFast, Reliable Home Additions & ADU Across Wilton Manors
Home additions and ADU construction in Wilton Manors typically run $45,000 to $130,000 for a room addition, and $90,000 to $220,000 for a new detached ADU, depending on whether your lot sits on a canal and whether your original seawall is still intact. We have been building in the Island City long enough to know that the canal-front parcels off NE 26th Drive have different problems than the interior streets near Wilton Drive. If you are planning an addition or ADU on a Wilton Manors lot, call (877) 610-1318 and we will walk the property with you before anyone writes a number.
Barrett & Sons Construction is the owner-operated crew that shows up with Tom Barrett’s name on the truck. We pull permits on every eligible job, we put every change in writing before a hammer swings, and we back the finished work with a 90-Day Done Right Promise. No franchise. No out-of-state call center. Just a live person on the phone, a crew that knows Wilton Manors’ canal codes, and a price that matches the one in your contract.
Why Barrett & Sons Construction Is Wilton Manors’s Preferred Home Additions & ADU Company
We have been building in South Florida since 1998, and the calls we get from Wilton Manors homeowners have a pattern. They bought a 1950s or 60s CBS ranch on a canal, watched property values climb, and now they want more square footage or an accessory dwelling unit for a family member or rental income. They also want a contractor who knows that Broward County plan reviewers will flag a failing 1950s concrete seawall before they will approve any rear-yard structure. That is not a surprise we discover on your dime. We check for it during the estimate.
Homeowners in Wilton Manors call us because Tom Barrett publishes his name, his address, and his license number. You can look it up before you sign anything. Our crews are background-checked and uniformed. When an inspector signs off on your new addition, we hand you the signed paperwork. If something is not done right, one call brings Tom back. That promise is written into every contract we sign in 33305.
We serve Wilton Manors with the same owner-operated crews that work the rest of Broward County. Dispatch and scheduling are coordinated from our Miami (South FL) office, and the crew that shows up at your Wilton Manors home answers to Tom Barrett, not a regional manager in another state. We also honor a permanent 10% Senior & Veteran discount, a free second opinion on any written estimate, and no trip charge inside the county.
If you want to know what our Home Additions & ADU team can do for your property, call us. We will tell you straight whether your lot needs a seawall assessment before we quote, because that changes the budget before it changes the bid.
Our Home Additions & ADU Services in Wilton Manors
ADU Design & Permitting
A detached ADU in Wilton Manors is not a shed with a bathroom. Broward County reviews the lot, the setback, the seawall, the water table, and the existing structure before anything gets approved. We handle the design, the engineering, and the permit package. If the plan reviewer flags your original seawall, we bring that to you with a written change order and a re-scoped draw schedule, not a surprise invoice after demolition starts.
Garage Conversion ADU
Converting a 1950s or 60s garage into an ADU in Wilton Manors almost always triggers the question of whether the rest of the house has to be brought up to current energy and wind code. It usually does. That means impact-rated openings, new roof-to-wall connections, and insulation upgrades on the existing structure. A typical garage conversion runs $30,000 to $80,000 in this market, and the range depends on whether you have terrazzo floors to save and jalousie windows to replace.
New Detached ADU
A new detached ADU on a Wilton Manors canal lot is one of the most involved builds we do on the Island City. You need a foundation that accounts for a water table just a few feet below grade, corrosion-resistant fasteners and rebar, plus a stem-wall or raised design to keep moisture away from the slab. On canal-front parcels, you may also need helical piers if the soil is soft and a seawall rebuild if the original 1950s wall is failing. Plan on $90,000 to $220,000, and we will give you an exact number after we see the lot.
Junior ADU & Interior Conversion
A junior ADU is an interior conversion, typically a single room with a kitchenette and a separate entrance, built within the footprint of an existing Wilton Manors home. These are often the fastest path to rental income because they do not require a separate foundation or site work. But they still fall under Broward County code for egress, fire separation, and impact-rated windows on any new openings. We handle the full scope from framing to final inspection.

Trusted Brands We Service in Wilton Manors
On Wilton Manors additions and ADUs, we spec materials that hold up to canal-adjacent humidity and salt air. That means PGT impact-rated windows on any new opening, Simpson Strong-Tie corrosion-resistant connectors on the framing, and GAF or CertainTeed membranes on any new or tied-in roof. We do not install mystery brands off a van. You can look up every product we put in your house.
We keep common materials for Wilton Manors jobs moving quickly because we know the supply yards and permit offices here. When a job needs a specific PGT impact window or a stainless fastener kit, we order it correctly the first time. Faster turnarounds, fewer missed deliveries, and no three-week wait for a part that should have been spec’d weeks earlier.
Common Home Additions & ADU Problems We See in Wilton Manors Homes
- Failing original seawalls triggering permit stops. Broward County plan reviewers routinely flag deteriorating 1950s and 60s concrete seawalls on rear-yard additions and detached ADUs. If the wall is within the rear setback, you may have to budget a full rebuild before any new structure can be approved. We scope this before we quote, not after.
- Chloride-driven corrosion on canal-adjacent framing. Salt air and canal proximity accelerate rust on standard galvanized fasteners and uncoated rebar. We spec epoxy-coated or stainless fasteners and concrete sealants on every Wilton Manors build. Skip this and you get cracking within a few years.
- High water table ruining conventional slabs. The water table on canal-adjacent Wilton Manors lots sits just feet below grade. A conventional slab poured without a raised stem-wall or proper drainage leads to damp subfloors, mold, and load-bearing problems after the first wet season. We design for this from the start.
- Older CBS homes failing wind and energy code during add-on work. Most of the 1950s-1970s concrete block homes in Wilton Manors still have original jalousie windows, flat or low-slope roofs with aging built-up membranes, and terrazzo floors. Any permitted addition triggers code review that often requires full replacement of those openings and roof-to-wall connections.

FAQs - Home Additions & ADU in Wilton Manors
Because Broward County plan reviewers will not approve a new structure within the rear setback of a canal-front lot if the original 1950s-60s concrete seawall is deteriorating or failing. The county flags it during the permit pull, and the rebuild becomes a condition of approval. We assess the seawall at the estimate stage so the cost is in the budget before the bid, not after. Call (877) 610-1318 to schedule a free estimate and we will check the wall while we are out there.
It means we cannot just pour a conventional slab and walk away. On canal-adjacent lots where the water table sits just feet below grade, we design a raised stem-wall foundation and often corrosion-resistant helical piers, plus concrete sealants and proper drainage to keep moisture out of the new structure. This adds scope and cost compared to a drier inland lot, and we show that in the written estimate before you sign anything.
Yes. Even if your lot is large and no zoning variance is required, Broward County still reviews the structural, energy, and wind components of any habitable addition or ADU. Permits pulled and inspections signed are standard on every eligible job we do. The permit inspector works for you, not for us, and we want their signature on every stage of the project.
Almost never. A garage conversion in Wilton Manors ties into the existing structure, and Broward County requires that the converted space meet current energy and wind code. That typically means upgrading impact-rated openings, insulation, and roof-to-wall connections on at least the converted area and often the connecting walls. We estimate the full scope up front so you are not surprised at the permit counter.
We spec epoxy-coated or stainless steel fasteners, uncoated rebar with proper concrete cover and sealants, PGT impact-rated windows on every new opening, and corrosion-resistant Simpson Strong-Tie connectors at all structural points. On canal-front lots, using standard galvanized hardware means visible rust and potential cracking within a few years. We will not spec that on a Wilton Manors build, and we will show you exactly what we are using in the written scope.
