Why Groundwork Construction Co. of South Florida Is Dania’s Preferred Home Additions & ADU Company
We’ve worked in Dania long enough to know that a garage conversion off Stirling Road isn’t the same job as one in a 1990s subdivision west of I-95. The concrete block homes built between the 1940s and 1960s, many with original flat roofs and 100-amp electrical services, demand a contractor who understands what’s lurking behind those plaster walls before demolition starts.
Our Home Additions & ADU team has completed projects throughout 33004, from junior ADUs near Dania Beach Boulevard to second-story additions in the historic district north of Griffin Road. Homeowners tell us the difference is our pre-construction assessment. We don’t just measure square footage; we test for salt-air damage to embedded rebar, verify whether your foundation can handle the load of an addition, and flag any FAA coordination your vertical construction might trigger.
Because we’re a single-source contractor, you won’t juggle separate architects, engineers, and trades. Raymond Estevez built Groundwork on the principle that one accountable team, working with materials you actually choose, beats the chaos of coordinating three or four different companies. From driveway to roofline, we handle every phase.
Our Home Additions & ADU Services in Dania
ADU Design & Permitting
ADU permits in Dania move through Broward County’s unified system, but with a critical local wrinkle: any structure that affects airspace near Fort Lauderdale-Hollywood International Airport needs FAA review. We’ve filed dozens of Form 7460-1 notices and know which projects trigger a full aeronautical study versus a simple determination of no hazard. Our design team draws plans that account for finished-floor elevations in Dania’s AE and VE flood zones from day one, so you’re not redesigning after the fact. ADU construction runs $90,000-$220,000 depending on size, utility connections, and whether you choose prefab or stick-built.
Garage Conversion ADU
Garage conversions are the fastest path to rental income or multigenerational living in Dania, typically costing $30,000-$80,000. Most Dania garages are detached concrete block structures from the 1950s or 1960s with galvanized hardware, minimal insulation, and electrical fed from a main panel that’s already undersized. We assess whether your existing slab meets current load requirements, upgrade electrical service if needed, and seal block walls against the salt-air corrosion that accelerates deterioration this close to the Atlantic. If the structure won’t support conversion economically, we’ll tell you before you’ve spent a dollar on drawings.
New Detached ADU
For homeowners with adequate lot coverage, a new detached ADU offers maximum flexibility. We build these stick-built or partner with prefab innovators like Mighty Buildings, Boxabl, and Plant Prefab for faster timelines. In Dania, site prep is often the wildcard: FEMA flood zone requirements may mandate breakaway wall designs or elevated piers for ground-level construction, and salt-air exposure means we spec stainless or hot-dip galvanized fasteners even where code doesn’t require them. You choose the brand and build path; we handle the FAA notice if your unit’s height or crane delivery affects FLL approach corridors.
Junior ADU & Interior Conversion
A junior ADU converts existing interior space, attached garage, or storage area into a self-contained unit with kitchenette and separate entrance. These projects avoid exterior footprint changes but still face Dania’s unique constraints. We recently converted a 1952 concrete-block garage into a junior ADU on a street off Federal Highway, just north of Dania Beach Boulevard. The original galvanized door was beyond repair, so we replaced it with a modern sectional door and sealed the block walls against salt-air intrusion. Our crew handled the FAA notice for the rooftop plumbing vent, which, while small, reminded us that Dania’s unique airspace rules touch every project, no matter the size.

Trusted Brands We Service in Dania
Groundwork works with 50+ recognized industry brands across every project category, so you’re never locked into a single manufacturer’s product line. For ADU and home addition projects, that means access to prefab partners including Mighty Buildings, Boxabl, Plant Prefab, and Tuff Shed alongside traditional lumber, truss, and SIP suppliers. On the interior side, we specify KraftMaid or Wellborn cabinetry, Cambria or Silestone countertops, and Andersen or Pella windows depending on your budget and whether you need impact-rated products for Broward’s High-Velocity Hurricane Zone. We don’t push what’s convenient to source. You choose the brand, we handle the build.
Common Home Additions & ADU Problems We See in Dania Homes
- FAA permit delays on vertical construction. Contractors unfamiliar with Dania routinely discover mid-project that crane operations or rooftop additions need a 45-day aeronautical study. We file Form 7460-1 before breaking ground, not after the stop-work order arrives.
- Structural upgrades on 1940s-1960s homes. Unreinforced masonry walls, undersized footings, and original 100-amp electrical services won’t pass modern Broward County inspections. We identify these during our initial assessment and build reinforcement into the budget, not as change orders.
- Salt-air corrosion of embedded steel. Dania’s position between the Intracoastal and the Atlantic accelerates rebar and fastener degradation in concrete block construction. We specify epoxy-coated rebar and stainless hardware where standard galvanized would fail within a decade.
- FEMA flood zone compliance for ground-level work. Much of 33004 sits in AE or VE zones requiring elevated finished floors and breakaway walls. Ignoring this during design means costly redesigns or failed final inspections.

FAQs - Home Additions & ADU in Dania
Yes, any construction that penetrates airspace near Fort Lauderdale-Hollywood International Airport’s approach corridors requires FAA Part 77 review, typically filed on Form 7460-1. This applies to crane operations, scaffolding above certain elevations, and any rooftop structure that might obstruct instrument flight paths. The review can take 45 days, so we file during design, not after permit submission. Call (844) 665-0162 and we’ll assess whether your specific project triggers this requirement during our free site visit.
Most Dania housing stock predates modern Florida Building Code wind-load and structural requirements, with unreinforced masonry, undersized electrical panels, and original flat roofs that can’t support additional load. Broward County inspectors will flag these issues before issuing a certificate of occupancy. We identify them upfront so your budget reflects reality, not optimism. For a detailed assessment of your specific property, call (844) 665-0162 for a free estimate.
Much of Dania falls within FEMA AE or VE flood zones, which mandate finished-floor elevations above base flood level and breakaway wall designs for any ground-level enclosed space. Ignoring this during design means permit rejection or costly mid-project redesign. We check FEMA maps and Broward County floodplain data before we draw a single plan. Call (844) 665-0162 to discuss how flood zone requirements affect your specific lot.
Yes, garage conversions are among our most requested Dania projects, typically running $30,000-$80,000. Success depends on whether your existing slab meets current load requirements, whether your electrical service can handle the additional demand, and whether the structure’s condition justifies conversion versus replacement. We assess all three during our initial site visit. Call (844) 665-0162 to schedule yours.
Dania’s proximity to both the Intracoastal Waterway and Atlantic Ocean accelerates corrosion of standard steel fasteners, anchor bolts, and exposed rebar by 30-50% compared to inland Broward sites. We specify hot-dip galvanized or stainless hardware, epoxy-coated rebar, and proper concrete cover over embedded steel to prevent premature failure. These aren’t upgrades; they’re standard on our Dania jobs. For material specifications tailored to your project, call (844) 665-0162.
