AfterFast, Reliable Home Additions & ADU Across Greenacres City
Most addition and ADU projects in Greenacres City run $45,000 to $130,000, with garage conversions starting lower and new detached units running higher. We work in Greenacres City every week, and we know what these jobs take before we ever write the first number down: CBS wall tie-ins, the high water table in the wet season, and a county building department that doesn’t rush for anyone. If you’re weighing an addition against a move, call (877) 610-1318 and we’ll give you a straight read on what your house will actually take.
Greenacres City wasn’t laid out for future additions on the fly. These are mostly 40 to 50-year-old concrete block and stucco homes on flat lots that were platted quickly in the 1970s and 1980s. That means the good news and the hard truth live side by side: the slab is usually sound, but the roofline, the electrical panel, and the drainage all need a real look before you start adding square footage. If your roof needs attention first, our Greenacres City Roofing team handles that as part of the plan. That’s the work we do every day.
Why Barrett & Sons Construction Is Greenacres City’s Preferred Home Additions & ADU Company
We’re Barrett & Sons Construction, founded in 1998 and still run by Tom Barrett and his sons. Tom lives twenty minutes from most Greenacres City jobs. If something’s wrong, he wants to know about it, and he answers his own phone at (877) 610-1318. That’s not a line on a website; that’s how the company has run for 29 years.
Greenacres City customers keep calling us back because we write every scope, every allowance, and every price change down before work starts. If the scope changes, you get a written change order first. No one on our crews is a stranger dispatched from a call center; they’re Tom’s sons and their teams, background-checked and uniformed. We pull permits on every eligible job and sit through the same Palm Beach County inspections you’d face with anyone else. The difference is we know how to sequence them so a failed rough inspection doesn’t cost you three weeks.
And yes, you can look us up. Tom Barrett publishes his name, address, and license number. Ask anyone on your street in Greenacres City, or check the license yourself before you sign anything. We’d rather you check.
Homeowners around here aren’t chasing the lowest bid. They’ve already learned how that story ends, and they’re done with it. They want a contractor who will still be around in six months if the drywall cracks or the door sticks. That’s why we put the 90-Day Done Right Promise on every contract: if it’s not done right, one call brings Tom back.
Our Home Additions & ADU Services in Greenacres City
Our Home Additions & ADU team handles the full range of work from a first-chair planning meeting to the final inspection. Here’s the honest shape of what that means in Greenacres City specifically.
ADU Design & Permitting
A detached ADU in Greenacres City is the project that tests local knowledge hardest. The water table sits two to four feet below grade during the June-October wet season, so drainage and slab elevation aren’t details you sort out later. They’re the first things the county reviewer looks at. We run the pre-application meetings, the drawings, the drainage calculations, and the permit package as one line of work. Expect a Greenacres City ADU construction budget of roughly $90,000 to $220,000 depending on size and finish level.
Garage Conversion ADU
More Greenacres City homeowners ask about garage conversions than any other ADU type, and the reason is simple: the footprint already exists and the slab is already poured. Most local garages are attached CBS structures, which makes the conversion structurally simpler than a ground-up build, but the electrical panel is often undersized for a dwelling unit. A garage conversion in Greenacres City typically runs $30,000 to $80,000 once you account for the panel, the insulation, the egress, and the county’s ADU requirements.
New Detached ADU
A new detached unit is a ground-up build, and in Greenacres City that means working with a lot that was graded decades ago for a different drainage pattern. We spend real time on the site plan before pricing anything. Detached ADUs here generally land between $90,000 and $220,000, with the final number moving on square footage, foundation type, and whether the unit needs its own utility drops or can tie into the main house. Inspectors specifically check roof-deck fastening patterns and Windows & Doors - Greenacres City opening protection under Florida’s high-velocity wind provisions, and we build that into our sequence from day one.
Junior ADU & Interior Conversion
For a smaller budget, a junior ADU or an interior conversion inside the existing footprint often makes more sense than adding a structure. Greenacres City’s stock of single-story CBS homes frequently has a underused Florida room or a large dining area that can convert cleanly. These projects are renovation-driven rather than addition-driven, and that changes the permit path and the cost. This is also where our Bathroom Remodeling in Greenacres City and Kitchen Remodeling in Greenacres City teams step in if the conversion includes a kitchenette or a second bath.

Common Home Additions & ADU Problems We See in Greenacres City Homes
- Undersized electrical panels. Many Greenacres City homes built in the 1970s and 1980s still carry the original 100-amp panel, which won’t pass a county inspection for a new dwelling unit or a permitted room addition. We flag it early so it’s a line item, not a surprise.
- Tie-in waterproofing at flat and low-slope rooflines. Flat roofs and low-slope rooflines are common on this era of Greenacres home, and the seam where an addition meets the existing roof is where leaks start. We detail those transitions carefully because the June-to-October rains will find any shortcut.
- Drainage and the high water table. Greenacres sits on former Everglades drainage land kept dry by the South Florida Water Management District’s canal network. The water table rises to within two to four feet of grade during the wet season, which affects every footer pour and slab addition in the city. We account for it before we pour, not after.
- Hurricane-code lag on older homes. Palm Beach County’s full hurricane exposure zone means any permitted addition triggers code checks on roof-deck fastening and opening protection. A 1970s CBS house often needs retrofit work to the existing structure just to let the addition pass. We tell you that before the permit goes in.
Pricing for Home Additions & ADU in Greenacres City, FL
The lead range for a home addition or ADU in Greenacres City is $45,000 to $130,000. That’s the honest middle for most permitted projects.
