Why Groundwork Construction Co. of South Florida Is The Acreage’s Preferred Home Additions & ADU Company
We’ve built throughout The Acreage’s unincorporated grid long enough to know that permits pull through Palm Beach County, not a city office, and that inspectors are covering enormous territory. That means we schedule inspections early in the week, before end-of-week delays stack up. Homeowners here appreciate that we don’t waste their time.
Our crews know the local housing stock - CBS construction from the mid-1980s through early 2000s, now hitting the age where electrical panels, plumbing, and rooflines need upgrading alongside any addition. We coordinate that work so you’re not hiring separate contractors.
Raymond Estevez built Groundwork on the principle that one accountable team beats a parade of subcontractors. In The Acreage, that matters more than most places. Your project doesn’t get handed off.

ADU Design & Permitting
Every ADU Design & Permitting in The Acreage starts with a site plan that respects Palm Beach County’s well and septic setbacks. Because there’s no municipal water or sewer, we measure distances to your wellhead and drain field before pencil touches paper. That geometry often pushes the structure toward the rear of your 1.25-acre lot, which changes how we route power, water lines, and access paths. We handle the county permit pull and inspection scheduling ourselves - locals know to avoid Friday inspections that can stall progress over a weekend.

Garage Conversion ADU
Converting an existing garage in The Acreage sounds straightforward until you factor in the slab elevation, the garage door’s structural role, and whether the space was built to residential code in the first place. Many garages here were constructed with lower slabs and minimal insulation. We assess whether the foundation can support living space, what the county will require for egress and utilities, and whether it’s smarter to convert or build new. On a recent project, we found the existing garage door springs pitted with rust and the rollers seized from years of salt-laden breezes. We replaced them with coated springs, stainless steel hardware, and nylon rollers, and installed a new opener chain rated for coastal use. Saved the homeowner a premature full-door replacement.

New Detached ADU
The Acreage New Detached ADU builds give you the most flexibility here, and we offer two build paths. Traditional stick-frame construction lets us match your existing home’s style and materials - James Hardie siding, KraftMaid or Wellborn cabinetry inside, Cambria countertops if you’re building out a full kitchen. Or we can go prefab with Abodu, Dvele, Mighty Buildings, or Boxabl for a faster timeline. Either way, the septic/well geometry drives placement. We’ve learned to design utility runs that cover distance without losing pressure or violating setback lines.

Junior ADU & Interior Conversion
The Acreage Junior ADU & Interior Conversion projects work inside your existing footprint - a basement, attic, or portion of the main house with a separate entrance. In The Acreage’s single-story CBS homes, we’re often looking at partitioning existing square footage or building above. These projects typically trigger fewer setbacks but still need county approval for egress, kitchenette plumbing, and electrical subpanels. We evaluate whether your current panel can handle the load; many 1980s-era homes here cannot.

Second Story Additions
Adding up instead of out is increasingly popular in The Acreage, especially where the well and septic occupy prime real estate near the main house. Second stories demand structural analysis of your existing CBS walls and foundation. We bring in engineering early, coordinate the roof tear-off and rebuild, and manage the window package - Andersen, Pella, Marvin, or impact-rated PGT and CGI depending on your wind zone and budget. The salt air means we spec hardware that won’t corrode out in five years.

ADU Site Prep & Utilities
Site prep in The Acreage is seasonal work. The water table rises to within 18-24 inches of grade during wet season, making slab pours and excavation tricky. We time major ground disturbance for drier months when possible, and we engineer fill and dewatering solutions when the calendar doesn’t cooperate. Every utility trench has to clear your drain field and well - we map that before we dig.

Room Additions & Sunrooms
Single-story room additions and enclosed patios need the same setback scrutiny as ADUs. We build to Florida Building Code wind standards, tie into your existing roofline with proper flashing, and specify materials that handle the humidity and salt. A sunroom that isn’t properly sealed becomes a greenhouse you can’t use six months a year.

Common Home Additions & ADU Problems We See in The Acreage Homes
- Salt-air corrosion on garage door hardware. Torsion springs snap in 5-7 years instead of the usual 10-12. Tracks rust and bind. Openers fail on humid Sundays. We spec coated springs, stainless hardware, and nylon rollers as standard on any project touching the garage.
- Outdated electrical panels that can’t handle addition loads. Homes built in the 1980s and 90s often have 100-amp service or Zinsco/Federal Pacific panels that insurers won’t cover. We identify this early and coordinate the service upgrade with FPL and the county.
- Seasonal water table interfering with foundations. Wet-season slab pours risk moisture intrusion and weakened concrete. We monitor conditions and adjust schedules, or engineer raised foundations where necessary.
- Permit delays from poor inspection timing. Palm Beach County inspectors cover vast territory. We book early-week slots and prep thoroughly so we don’t burn a trip.

FAQs - Home Additions & ADU in The Acreage
Garage door torsion springs in The Acreage corrode and snap in 5-7 years, roughly half the lifespan you’d see in inland Palm Beach County. The salt-laden air pits the steel, creating stress risers that fail under load. We replace failed springs with coated versions and upgrade to stainless hardware and nylon rollers as standard practice. Call (844) 665-0162 if your door is making noise or hanging unevenly - estimates are free.
Palm Beach County requires minimum setbacks of 75 feet from septic drain fields and 50 feet from private wells for any new residential structure, though exact distances can vary based on your septic system type and well depth. On The Acreage’s standard 1.25-acre lot, this often forces the ADU toward the rear property line and changes how we route utilities. We survey your site and coordinate with the Florida Department of Health for septic permits before finalizing any design.
The driest months - typically November through April - are ideal for slab work in The Acreage, when the water table sits lower and soil conditions stabilize. During wet season, the water table can rise to within 18-24 inches of grade, making proper compaction and moisture barriers critical. We monitor conditions weekly and will delay a pour rather than risk a compromised foundation. Call (844) 665-0162 to schedule a site evaluation and we’ll advise on timing.
Install an opener with a sealed housing and a chain rated for coastal use, not a standard residential model. We recommend units with stainless or coated chain drives and circuit boards conformally coated against humidity. Annual inspection of the chain tension, safety sensors, and logic board connections catches early corrosion before it kills the unit. If your opener is more than five years old and exposed to garage air flow, have us check it - premature failure is common here.
Because The Acreage is unincorporated, all permits pull through Palm Beach County Building Division. A typical garage conversion requires foundation/slab, framing, rough electrical, rough plumbing, insulation, drywall, final electrical, final plumbing, and final building inspection. Some projects also need Florida Department of Health approval if you’re adding a kitchenette or bathroom remodeling in The Acreage that affects septic loading. We schedule inspections early in the week to avoid the county inspector’s route backlog on Thursdays and Fridays.
