AfterFast, Reliable Home Additions & ADU Across Fountainebleau
Fountainebleau sits in unincorporated Miami-Dade County, a neighborhood where most homes are concrete block structures built between the 1960s and 1980s, long before Hurricane Andrew rewrote the building codebook. Adding square footage or an ADU here means working with Miami-Dade’s High-Velocity Hurricane Zone requirements, and that’s where local knowledge separates a smooth project from a stalled one. Barrett & Sons Construction answers the phone at (877) 610-1318 with a person, not a voicemail box, and Tom Barrett has been pulling Miami-Dade permits since 1998. We know the county inspection process, the NOA documentation rules, and how to keep your addition moving in a neighborhood where the water table sits just a few feet down. If you’re planning a room addition, garage conversion, or a detached ADU in the 33172 ZIP, call us first.
Why Fountainebleau Homeowners Call Barrett & Sons for Additions
Most Fountainebleau homeowners we meet have been through the wringer before. A national outfit quotes one number on the phone, shows up with another, and the permit inspector never appears. That’s not how we work. Tom Barrett’s name, address, and license number are published so you can verify exactly who you’re hiring before anything gets signed. His sons run the crews. The people who shake your hand at the estimate are the same people swinging hammers on Tuesday.
Fountainebleau is unincorporated Miami-Dade, so permits don’t run through a city hall like they do a mile away in Doral. Every addition or ADU we build here goes through the Miami-Dade County Building Department, and we handle that paperwork start to finish. We know which products carry the required Miami-Dade Notice of Acceptance, because an assembly without an NOA won’t pass inspection no matter how well it’s installed. That’s the kind of detail that catches out-of-area subs flat-footed.
Our customers in Fountainebleau leave reviews that mention the same things: written change orders before any scope shifts, permits pulled on every eligible job, and crews who clean up at the end of the day. The 90-Day Done Right Promise goes on every contract in writing. If something’s not right, one call brings Tom back.
Our Home Additions & ADU Services in Fountainebleau
ADU Design & Permitting
Before any concrete gets poured, an ADU in Fountainebleau has to pass Miami-Dade’s HVHZ plan review. We handle the drawings, the structural calcs, and the county submittal, and we sit with the plan reviewer when questions come up. Detached ADU construction in 33172 typically runs $90,000 to $220,000, with design and permitting folded into that number. Every allowance and scope item arrives on paper, because an allowance that isn’t on paper is a surprise waiting for a date.
Garage Conversion ADU
A garage conversion is the speediest path to rental income or a mother-in-law suite in Fountainebleau’s 1960s-1980s stock. Most existing garages here are CBS construction, which is a good starting point for conversion. Typical garage conversions in Fountainebleau run $30,000 to $80,000, depending on whether the existing slab needs rework and whether plumbing has to be trenched through oolitic Miami Limestone. We bring in dewatering planning during the June-to-October wet season so trenching doesn’t turn into a swimming pool.
New Detached ADU
A new detached ADU on a Fountainebleau lot means new footings, new slab, and a full envelope built to Miami-Dade’s wind-load standards. We specify windows and doors that carry a Miami-Dade NOA, typically Andersen or Marvin lines, because anything else gets kicked back at plan review. Your $90,000 to $220,000 budget covers design, permits, foundation, framing, rough-in, finishes, and final inspection. The permit inspector works for you, not for me, which is exactly why I like him.
Junior ADU & Interior Conversion
Not every Fountainebleau home needs a whole detached structure. A junior ADU inside the existing footprint, often a converted den or enclosed patio, typically falls inside the $45,000 to $130,000 range for a full Interior Conversion with kitchenette and bath. These projects still require county permits and HVHZ-compliant assemblies, but they dodge the site work and foundation costs that push detached units higher. We’ll tell you honestly whether your interior space will pencil out before you spend a dime.

Trusted Brands We Service in Fountainebleau
When we install GAF roofing products on a new addition or an enclosed sunroom in Fountainebleau, you’re getting a name you can look up, rated for Miami-Dade’s wind zone and backed by the manufacturer’s warranty. Schluter systems go into wet areas like ADU bathrooms and kitchenettes because they hold up in South Florida’s humidity. We stock common parts locally so a warranty call in 33172 doesn’t turn into a two-week wait. You won’t see mystery brands off the back of a van on our jobs.
Common Home Additions & ADU Problems We See in Fountainebleau Homes
- Undersized footings and slabs that predate Andrew. Many 1960s-1980s CBS homes in 33172 were built before modern wind-load requirements, and their existing slabs often lack the reinforcement depth a new addition ties into.
- Groundwater intrusion during trenching. The water table sits 2 to 4 feet below grade across much of Fountainebleau, so any plumbing or electrical trench in the wet season needs dewatering before the first shovel goes in.
- Non-NOA windows and doors from out-of-area suppliers. A hurricane-rated assembly that passes in Broward County often lacks the Miami-Dade Notice of Acceptance required in Fountainebleau, and it fails plan review every time.
- Permit confusion from the county-city seam. Fountainebleau is unincorporated Miami-Dade, and subcontractors who spend most of their time in incorporated cities like Sweetwater or Doral routinely show up expecting municipal scheduling rules that don’t apply here.
Pricing for Home Additions & ADU in Fountainebleau, FL
A home addition in Fountainebleau generally runs $45,000 to $130,000, while a detached ADU ranges from $90,000 to $220,000 and a garage conversion lands between $30,000 and $80,000. What moves the number most is site conditions, foundation work, and whether the county requires structural upgrades to the existing building before the addition ties in.
