How Much Does a Garage Conversion ADU Cost in Dania, FL?
A garage conversion ADU in Dania typically runs $30,000-$80,000 and takes 8-14 weeks from permit approval to final inspection, depending on whether the existing slab, roof, and electrical service need upgrading. Most Dania homeowners we work with are converting 1-car or 2-car garages attached to 1950s-1960s concrete block homes in neighborhoods near Dania Beach Boulevard or US-1, where the goal is adding rental income or housing family without expanding the home’s footprint. Call (844) 665-0162 and we’ll walk your specific garage and give you a written estimate, usually within 48 hours.
How We Convert a Dania Garage Into a Legal ADU
Every garage conversion ADU follows the same sequence, but the timeline stretches or compresses based on what your existing structure can handle. Here’s how we break it down on a typical Dania job.
Stage 1: Structural and utility assessment (3-5 days)
We open the walls and evaluate the slab thickness, roof structure, and whether your electrical panel can handle a full dwelling unit. In Dania, we regularly find 100-amp services and ungrounded wiring in garages that haven’t been touched since the original build. You’ll decide here whether to upgrade to 200 amps or add a subpanel, and whether the existing concrete slab meets current flood-zone elevation requirements. We bring in a structural engineer at this stage if the roof needs reframing for insulation and drywall.
Stage 2: Design, permitting, and FAA coordination (4-8 weeks)
Because Dania sits directly beneath Fort Lauderdale-Hollywood International Airport’s primary approach corridors, any scaffolding or crane work above certain elevations triggers mandatory FAA Part 77 airspace review and a Form 7460-1 filing. This is a standard pre-construction step for us, but it routinely catches out-of-town contractors off guard and can add 45 days if not handled upfront. While that processes, we finalize your floor plan, window schedule, and mechanical layout with Broward County Building Division. You’ll choose your finishes now, kitchenette configuration, and whether you’re adding a separate meter.
Stage 3: Demolition, slab and framing modifications (1-2 weeks)
We strip the garage to studs, cut in any new window or door openings per the approved plans, and address slab issues. Dania’s AE and VE flood zones often require us to raise finished-floor elevations or install breakaway wall sections for ground-level conversions. If your garage has a low-slope built-up roof, we may need to reframe for proper insulation depth and positive drainage. This is where we also rough in plumbing if you’re adding a bathroom or kitchenette.
Stage 4: Mechanical, electrical, and insulation (2-3 weeks)
HVAC mini-split installation, electrical rough-in with arc-fault and GFCI protection, plumbing pressure tests, and closed-cell spray foam or mineral wool insulation to meet Florida energy code. We coordinate inspections at this point, mechanical, electrical, plumbing, and framing. Salt-air corrosion in Dania means we specify stainless or galvanized fasteners and hardware for any exposed structural connections.
Stage 5: Finishes, final inspection, and certificate of occupancy (2-3 weeks)
Drywall, flooring, cabinetry, fixtures, paint, and trim. We walk you through the final punch list, then call for Broward County’s final inspection. Once you have your CO, the unit is legal for occupancy or rental. Most homeowners who are doing this as part of a full property upgrade also ask us about Home Additions & ADU in Dania at this stage, planning the next phase while we’re still on site.
The Build Choices That Shape Your Garage Conversion ADU
- Kitchenette vs. wet bar vs. none: A full kitchenette with range, sink, and refrigerator adds $8,000-$18,000 but makes the unit rentable as a standalone dwelling. A wet bar with mini-fridge and microwave drops that to $3,000-$6,000, suitable for guest use only. No plumbing at all saves the most but limits resale and rental value. We typically see Dania homeowners who want rental income opt for the full kitchenette.
- Bathroom addition vs. existing plumbing: If your garage shares a wall with an existing bathroom, tying into that stack saves $4,000-$7,000 versus running new sewer and vent lines across the slab. But many Dania garages are detached or on the opposite end of the house, making a new bath the only option. You’ll decide based on the layout and your budget.
- Slab insulation and moisture barrier: Florida garages rarely have insulated slabs. We offer rigid foam insulation with a vapor barrier ($2,500-$5,000) or a raised subfloor system ($4,000-$8,000) that creates an air gap and drainage plane. The raised system performs better long-term in flood-prone areas but reduces ceiling height, critical if you’re already near the 7.5-foot minimum for habitability.
- Impact-rated windows and doors: Required by code in Broward County’s High-Velocity Hurricane Zone. Standard vinyl impact windows from PGT or CGI run less than architectural aluminum, but the frame sightlines are thicker. We walk you through the pressure ratings and aesthetics for your specific opening sizes.
- HVAC approach: Ductless mini-split is the default for garage conversion ADU work, $3,500-$7,500 installed depending on BTU load and whether you want a heat pump for the occasional cold snap. Extending your central system is rarely practical, the ductwork and load calculations usually don’t support it, and code requires independent temperature control for ADUs anyway.
Homeowners often pair the interior finish work with Cabinets & Countertops in Dania to match the new ADU kitchenette with a main-house remodel, or with Backsplash, Tile & Flooring in Dania for consistent flooring transitions.
What Garage Conversion ADU Costs in Dania, FL
| Component | Low Range | High Range |
|---|---|---|
| Basic garage conversion ADU (no bath, minimal electrical) | $30,000 | $45,000 |
| Mid-range with kitchenette and 3/4 bath | $45,000 | $65,000 |
| Full conversion with structural upgrades, flood elevation work, premium finishes | $65,000 | $80,000 |
Five factors push your number up or down:
1. Existing garage condition. A 1960s block garage with a sound slab, adequate headroom, and a roof that can take insulation needs less work than one with spalling concrete, termite-damaged framing, or a flat roof holding ponding water. We’ve seen $12,000 swings just from slab and roof remediation.
2. Plumbing and electrical relocation. New sewer lines across a slab, upgrading from 100 to 200 amps, or running gas for a range, each add $3,000-$8,000. If your main panel is already maxed out and located on the opposite side of the house, expect the higher end.
3. Flood-zone requirements. Much of Dania falls in AE or VE zones. If your finished floor needs elevation, breakaway wall design, or flood vents, that adds $2,000-$6,000 in materials and engineering.
4. Material and fixture grade. Stock cabinetry from Wellborn or KraftMaid, LVT flooring, and standard quartz from Cambria keep costs controlled. Moving to custom built-ins, large-format porcelain, or premium stone surfaces can add 30-40% to the finish budget.
5. Permit scope and FAA coordination. A straightforward conversion with no exterior work above the existing roofline avoids FAA filing. Any crane, scaffolding, or rooftop mechanical that penetrates the approach surface triggers the Form 7460-1 process, adding time but typically only $500-$1,500 in filing and engineering fees.
Our written estimates itemize labor, materials, permits, and a contingency line for concealed conditions. They don’t include temporary relocation costs, utility connection fees charged by the city, or HOA approval expenses if your neighborhood requires them.
What Dania Homes Specifically Do to This Job
Dania’s housing stock works against easy conversions. As one of Broward County’s oldest cities, the 1940s-1960s concrete block and wood-frame homes we most often see near Sheridan Street or along the Intracoastal were built before Hurricane Andrew rewrote Florida’s building code. Original flat or low-slope built-up roofs, common in this era, don’t have the structural margin for modern insulation and drywall loads without sistering rafters or reframing entirely. Undersized electrical services, 60 or 100 amps, were standard when these homes went up and can’t handle the additional demand of a dwelling unit with cooking, cooling, and hot water.
The salt-air environment between the Intracoastal and the Atlantic accelerates corrosion in steel fasteners, anchor bolts, and any exposed rebar in the original slab. We specify hot-dip galvanized or stainless hardware for structural connections, and we inspect existing embedded steel more carefully than we would five miles inland. Flood-zone requirements add another layer, finished-floor elevations, breakaway wall design, and proper venting aren’t optional add-ons here, they’re code mandates that shape the foundation work.
And then there’s the FAA factor. Contractors pulling permits for any work that might require rooftop equipment or elevated scaffolding in Dania routinely discover what local builders already know, that Form 7460-1 filing and potential 45-day aeronautical study is part of the standard pre-construction sequence. Same trade work in Davie or western Hollywood doesn’t face this constraint. We’ve handled enough of these filings that they’re routine for our team, but they can derail a project timeline if discovered mid-process by a builder unfamiliar with FLL’s instrument approach corridors.
Our Home Additions & ADU crew covers Dania alongside Fort Lauderdale, Dania Beach, and Hallandale, so the local conditions, inspectors, and permit pathways are familiar territory.

Frequently Asked - Garage Conversion ADU in Dania
From permit approval to certificate of occupancy, expect 8-14 weeks. The variable is usually pre-construction, FAA coordination if needed, and whether your existing slab and roof need structural work. Call (844) 665-0162 and we can give you a tighter range after seeing your specific garage.
Yes. Broward County requires building, electrical, plumbing, and mechanical permits, plus zoning verification that your property qualifies for an ADU under current code. We handle the full permit package, including any FAA filings if the work requires elevated equipment. Never proceed without permits, an unpermitted ADU can’t be legally rented and will block a future sale.
Sometimes, but rarely for a legal dwelling unit. Florida code requires a kitchenette, bathroom, independent HVAC, and adequate electrical service for habitable ADUs. If your garage already has a sink and your panel has spare capacity, you might avoid major utility relocation. Most Dania homes we see need at least electrical upgrades and new plumbing for a bath or kitchenette.
Generally yes. A garage conversion ADU in Dania runs $30,000-$80,000, while detached ADU construction typically starts at $90,000 and runs to $220,000. You’re leveraging existing walls, roof, and slab rather than building from scratch. The savings shrink if your garage needs extensive structural, flood, or utility work to meet code.
We warranty our workmanship for one year from final inspection, and all materials carry their manufacturer warranties, impact windows from PGT or CGI, cabinetry from KraftMaid or Wellborn, countertops from Cambria, and so on. We provide warranty documentation for every product at project closeout. For warranty service, you call us directly, not a separate trade contractor.
