What Does a Garage Conversion ADU in Broadview Park Involve?
A garage conversion ADU in Broadview Park transforms your existing attached or detached garage into a permitted, habitable living unit with its own kitchenette, bathroom, sleeping area, and separate entrance. Most conversions we handle in this unincorporated Broward County community run 4 to 7 months from permit approval to final county inspection, with the build phase itself typically spanning 10 to 14 weeks. In Broadview Park’s market, you’re generally looking at $30,000 to $80,000 depending on whether you’re working with a bare slab and block walls or a structure that needs significant remediation first. Call (844) 665-0162 and we’ll walk your specific garage with you, no charge.
How We Convert a Garage Into an ADU in Broadview Park
Every garage conversion ADU follows a sequence, but the order matters more than people realize. Here’s how we stage it for Broadview Park’s county-permit environment and the older housing stock we typically encounter.
Stage 1: Feasibility and existing conditions assessment (1-2 weeks)
We measure the garage footprint, photograph the slab condition, and test for moisture intrusion through the floor, which is common in Broadview Park given the high water table during wet season. You’ll decide at this point whether you’re keeping the garage door opening as a framed wall with windows or installing a code-compliant entry door. We also flag whether your main electrical panel has capacity for a subpanel, since Federal Pacific and Zinsco panels we find here almost always require full replacement to meet Broward County’s current standards.
Stage 2: Design and Broward County ePlan submission (3-6 weeks)
Our draftspeople produce plans showing the new layout, structural connections, and Florida Building Code compliance for wind and impact resistance. Because Broadview Park is unincorporated, everything routes through the county’s ePlan portal rather than a city building department, which changes the review timeline and the corrections process. You’ll approve fixture locations, window sizes, and whether we’re specifying impact-rated products or standard windows with shutters. This is also when we coordinate with the county on setbacks and parking replacement requirements.
Stage 3: Demolition and rough structural work (2-3 weeks)
We strip the interior, remove the garage door and track system, and frame the new wall assembly at the former opening. If the slab slopes for drainage, we evaluate whether grinding or a new floating floor system makes more sense. Plumbing rough-in for kitchenette and bathroom goes in now, including any grinder pump if the main sewer line sits above the garage slab level, which we’ve encountered on properties near the lower-lying edges of Broadview Park.
Stage 4: Mechanical, electrical, and insulation rough-in (2-3 weeks)
HVAC gets tricky in garage conversions. We typically specify a ductless mini-split for efficiency and zoning independence, though some clients prefer tying into the main house system if capacity allows. Electrical includes the subpanel, GFCI and AFCI protection throughout, and dedicated circuits for the kitchenette appliances. Insulation must meet current energy code, which means more than the bare block walls most original garages offer. You’ll choose your insulation approach here: closed-cell spray foam for the tightest envelope, or rigid foam with batt backup for budget control.
Stage 5: Finishes, fixtures, and county final inspection (3-4 weeks)
Drywall, flooring, cabinetry, countertops, tile, and trim happen in sequence. We schedule Broward County’s final inspection only after passing our own punch walk with you. The county inspector verifies egress window operation, smoke and CO detector placement, and that the unit is properly labeled as an ADU with address posting. We don’t hand over keys until that’s signed off.
The Material and Configuration Choices You’ll Make
Garage conversion ADU projects in Broadview Park force specific decisions that affect cost, comfort, and how the unit performs during hurricane season. Here’s where homeowners typically pause and weigh options:
- Window and door rating: Standard vinyl windows with hurricane shutters cost less upfront but require manual deployment before a storm. Impact-rated windows from lines like PGT or CGI stay in place year-round and qualify for insurance discounts, though they add $3,000-$7,000 to a typical conversion. For the new entry door, we generally recommend impact-rated fiberglass unless the client explicitly prefers aluminum with a shutter system.
- Floor system over sloped slab: Grinding the existing slope flat is cheapest but creates dust and reveals any slab cracks. A self-leveling underlayment with luxury vinyl plank or tile on top runs middle range. A raised sleeper floor with insulation beneath performs best thermally and allows plumbing to run underneath, though it steals 3-4 inches of headroom, which matters in older Broadview Park garages with 8-foot ceilings.
- Kitchenette scope: A wet bar with mini-fridge and microwave drawer keeps the footprint tight and the permit simpler. A full two-burner cooktop with range hood and apartment-size dishwasher requires grease-duct venting and more elaborate fire separation from sleeping areas. Most rental-oriented ADUs we build in Broadview Park go with the fuller kitchenette; in-law units often stay simpler.
- Bathroom layout: Compartmentalized wet bath (shower over toilet, wall-hung sink) fits in 25 square feet and keeps plumbing consolidated. A separated three-fixture bath needs 35-40 square feet and typically requires moving the main drain line, which adds cost in concrete slab construction. We map the existing underground plumbing before you commit.
- Exterior finish match: James Hardie siding can be matched to most existing home exteriors in Broadview Park, where we see a mix of original stucco, painted block, and later-added vinyl. Matching exactly matters less for rental ADUs than for in-law quarters where visual cohesion affects property value perception.

What Broadview Park Homes Specifically Do to This Job
Broadview Park’s unincorporated status changes the permit path for every garage conversion ADU we build here. There’s no city building department to walk plans into. Everything submits through Broward County’s ePlan portal, and inspectors schedule through the county system, not a local office. Contractors accustomed to Plantation or Lauderhill’s municipal workflows often stumble on the transition, which is why we maintain dedicated ePlan credentials and direct county inspector relationships.
The housing stock matters just as much. Most Broadview Park garages we’re converting sit on 1950s-1970s concrete block ranch homes with original single-pane jalousie or aluminum windows, low-slope roofs, and electrical panels that predate modern AFCI requirements. That means the garage conversion ADU almost never exists in isolation. The project typically surfaces needed upgrades to the main house’s electrical service, and the county inspector will flag any accessible deficiencies in the primary structure during the ADU inspection cycle.
Wind mitigation is non-negotiable. Pre-1994 construction in Broward County must meet current Florida Building Code standards for the converted space, which often means reinforcing the roof-to-wall connection, adding hurricane straps where they’re missing, and proving the new windows and doors meet the pressure ratings for this exposure zone. We build that compliance work into our initial assessment so you’re not mid-project when the inspector asks for it.
Water table reality shapes the foundation work too. In the wet season months from May through October, we’ve hit groundwater within 18 inches of grade on properties near the lower fringe of Broadview Park. Any trenching for utility runs or drainage improvements requires dewatering and controlled backfill, which we schedule outside peak hurricane season when possible to avoid both rain delays and the permit backlog surges that follow named storms.

Frequently Asked - Garage Conversion ADU in Broadview Park
From signed contract to certificate of occupancy, most Broadview Park garage conversion ADU projects take 4 to 7 months, with the construction phase accounting for 10 to 14 weeks of that. Broward County’s ePlan review typically adds 3 to 6 weeks before we can pull the permit and start work. Call (844) 665-0162 and we can give you a tighter timeline based on current county review speeds.
Yes, and because Broadview Park is unincorporated Broward County, the permit comes from the Broward County Building Division, not a city office. The permit covers structural, electrical, plumbing, and mechanical work, plus Florida Building Code compliance for wind and energy. We handle ePlan submission, corrections, and inspection scheduling as part of our standard process.
Sometimes, but rarely in Broadview Park’s older housing stock. The original garage slab usually lacks rough-in for sewer and water, and the main electrical panel often lacks capacity for an additional subpanel. We design to minimize new trenching and conduit runs, but some extension of utilities is almost always necessary for a code-compliant kitchenette and bathroom.
A garage conversion ADU in Broadview Park typically costs 30% to 50% less than a new detached ADU because you’re working with existing walls, roof structure, and foundation. The $30,000-$80,000 range for conversion compares to $90,000-$220,000 for detached construction. The trade-off is less design flexibility and the constraints of the existing footprint.
We warranty our workmanship for one year from final completion, and all materials carry their manufacturer warranties, which range from 10 years to lifetime depending on the product line. We register warranties in your name for items like windows, roofing, and major appliances so you’re covered even if you sell the property. Ask us for specific warranty documentation on any product during the selection phase.
