Home Additions & ADU in Leisure City - One Fixed Price, Permits Handled

Fast, Reliable Home Additions & ADU Across Leisure City

Adding square footage to a Leisure City home is not the same job as adding it anywhere else in Florida. The zip code 33033 carries a construction history most of the country only reads about. A home addition here runs $45,000 to $130,000 for most projects, and a full detached ADU typically lands between $90,000 and $220,000. Those numbers reflect the High-Velocity Hurricane Zone standards, the limestone under your lot, and the permit process Miami-Dade runs.

Why Barrett & Sons Construction Is Leisure City’s Preferred Home Additions & ADU Company

We are the Home Additions & ADU team people in Leisure City call when the first contractor’s quote didn’t survive contact with the building department. Tom Barrett has been running Barrett & Sons since 1998, and he does not hand your job to strangers. His sons run the crews, and Tom’s name goes on the contract, not a logo. Homeowners checking us out usually do the same thing: they look up the license number, read the 90-Day Done Right Promise, and call on a Saturday. A live person answers, because somebody is always on the phone. That matters when you’re spending six figures on a project your grandkids will inherit.

What we know about Leisure City specifically is something no franchise operation can fake. We know which streets still hold original 1960s concrete block and stucco homes that survived Andrew with patched roofs and retrofitted ties, and which lots got the full post-Andrew rebuild treatment. We know that a home addition on one side of a street may require a completely different wall-tie and roof-to-wall connection detail than the house across from it. That’s not trivia. That’s the difference between a permit that clears inspection and one that sits on hold. We do not treat Leisure City as a generic Miami-Dade suburb, because it isn’t one.

We stock or order locally for homeowners here, so you’re not waiting for a part to come from a warehouse in Georgia. And every price change on your addition or ADU shows up as a written change order before work moves. No surprise invoices at the end, because an allowance that isn’t on paper is a surprise waiting for a date. That approach has built our standing in this community one job at a time, and plenty of our calls start with, “You did the addition down on my street.” Ask anyone on your street, or look up the license number yourself.

Our Home Additions & ADU Services in Leisure City

We handle the full range of addition and ADU work in Leisure City, from the first sketch to the final inspection sticker. Here are the four most common requests we see in 33033.

ADU Design & Permitting

Nearly every ADU in Leisure City starts with a conversation about Miami-Dade product approvals. We design ADUs around materials that already hold Miami-Dade NOA numbers, because the inspector will check and the last thing you want is a rejected window order delaying your project by six weeks. We pull the permits, we meet the inspectors, and the permit inspector works for you, not for me, which is exactly why I like him. Typical ADU design and permitting in Leisure City runs from $90,000 to $220,000 once construction, materials, and federal, county, and town requirements are tallied.

Garage Conversion ADU

Many Leisure City homes built after 1992 have garages that were designed to code but never finished as living space. Converting one into an ADU runs $30,000 to $80,000. The biggest variables here are the slab elevation and the existing roof ties. On the low-lying lots along the eastern side of the community, we often have to raise interior floor elevation slightly to satisfy flood and drainage requirements, and that number changes the quote fast.

New Detached ADU

A new detached ADU in Leisure City is not just a small house in the backyard. The water table sits just inches below grade during the wet season from June through October, so we pay close attention to dewatering and slab design before a single form goes up. A new detached ADU here typically runs $120,000 to $220,000. The final cost depends on whether you want a studio or a two-bedroom layout, and whether the county requires a separate power drop, which it often does on this side of Miami-Dade.

Junior ADU & Interior Conversion

Some Leisure City homeowners don’t need a full second unit. They need a private suite with its own entrance inside the existing footprint. Junior ADUs and interior conversions run $45,000 to $130,000 depending on whether we are repurposing a den, converting a formal living room, or finishing out a large covered patio. These jobs tend to move a little faster because the shell already exists, but the same HVHZ rules apply when we cut new openings or add a second entry door.

Trusted Brands We Service in Leisure City

We carry and install brands you can look up, not mystery products off a van. For ADU bathrooms and kitchens in Leisure City, we install Schluter waterproofing systems under tile, and Grohe fixtures where the customer wants European plumbing hardware. On any roof, including the new pitched roof on a detached ADU, we use GAF materials that already hold the Miami-Dade product approvals the county wants to see. If it goes into a Leisure City home, it already has its paperwork in order before it gets loaded on the truck.

Common Home Additions & ADU Problems We See in Leisure City Homes

• HVHZ product mismatches: Contractors quote windows or doors with Florida statewide approvals and then act surprised when Miami-Dade rejects them. In Leisure City, the fix is simple: every product must carry a Miami-Dade NOA. We only quote products that already have one.
• High water table and slab movement: The Miami Limestone formation means ground water can sit within inches of grade during the June to October wet season. Any ground-level slab or stem wall needs a dewatering plan and often a thickened edge. We design for it before the first inspection.
• Pre-Andrew construction quirks: The original CBS homes built in the 1960s through the 1980s have roof-to-wall connections and wall ties that vary house by house, often patched after the storm. Tying a new addition into one of those structures means we inspect what’s actually there before we draw what goes next to it.
• Zero-lot drainage conflicts: Leisure City’s flat terrain and tight lots mean stormwater has nowhere to go naturally. A new ADU changes your drainage pattern, and if we don’t address it early, the county will flag it late. We build the drainage plan into the permit package, not as an afterthought.
