What Does a Garage Conversion ADU Cost and Involve in Lauderhill?
A garage conversion ADU in Lauderhill transforms your existing garage into a permitted, conditioned living unit with its own kitchenette, bathroom, and separate entrance. Most projects we handle here run $30,000-$80,000 and take 10-14 weeks from permit approval to final inspection, though Lauderhill’s older housing stock often adds structural compliance work that newer cities don’t face. Call (844) 665-0162 and we’ll walk your specific garage and give you a written estimate with no pressure.
How We Convert a Garage to an ADU - Start to Finish
We’ve done enough of these in Lauderhill to know where the surprises hide. Here’s the actual sequence, with what you’re deciding at each point and how long each stage typically takes.
Stage 1: Site evaluation and feasibility (3-5 days)
We measure your garage, check ceiling height, and verify whether the slab can support a conditioned space without major modification. In Lauderhill, we’re often looking at 1950s-1970s CBS construction with flat roofs and minimal tie-downs, so we flag structural issues early. You’ll decide at this stage whether you want a full kitchen or a kitchenette, and whether the bathroom can tap into existing plumbing lines or needs new trenching.
Stage 2: Design and permit drawings (2-3 weeks)
Our draftsperson produces plans that satisfy Broward County’s current Florida Building Code requirements. Because Lauderhill’s pre-Andrew housing stock predates modern wind-resistance standards, we almost always need to detail roof-to-wall strap retrofits and impact-rated openings in these drawings. You’ll choose your window and door specs here - PGT and CGI both make impact-rated options that satisfy code without looking institutional.
Stage 3: Structural prep and rough utilities (2-3 weeks)
This is where the real work starts. We may need to cut the slab for plumbing trenches, reinforce the roof structure for added load, and install proper strapping to bring the whole assembly up to current FBC standards. Lauderhill’s seasonally high water table means we pay particular attention to waterproofing any below-grade penetrations. You’ll be deciding on electrical panel capacity - many older garages here are fed by a single 20-amp circuit, and an ADU needs far more.
Stage 4: Insulation, drywall, and finishes (3-4 weeks)
We close in walls, run HVAC mini-split lines, and install your chosen finishes. This is where material choices matter most. You’ll pick flooring that handles South Florida humidity, cabinetry that fits the compact footprint, and countertop material. Silestone and Caesarstone both hold up well in the humidity, though if you’re budget-conscious, a solid-surface alternative can free up funds for better windows or upgraded insulation.
Stage 5: Final inspection and certificate of occupancy (1-2 weeks)
Broward County inspectors verify structural compliance, electrical safety, plumbing function, and energy code adherence. In Lauderhill, the structural review tends to be more thorough than in newer suburbs because of the age of the housing stock. Once we pass, you have a legal, rentable ADU that adds real value to your property.
The Options You’ll Choose Between for Your Garage Conversion ADU
Every decision below moves your number and shapes how the space lives. We don’t push one path - we explain the trade-off and let you decide what fits your budget and how you’ll use the unit.
- Kitchenette vs. full kitchen: A kitchenette with a mini-fridge, two-burner cooktop, and compact sink runs $3,000-$6,000 and satisfies most ADU ordinances. A full kitchen with standard appliances, custom cabinetry, and stone counters adds $8,000-$18,000. If you’re housing family long-term, the full kitchen pays off. For rental income, the kitchenette often rents nearly as well for far less upfront.
- Wet bath vs. standard bathroom: A wet bath - where the shower shares the floor space with the toilet and sink - fits in 25 square feet and costs $4,000-$7,000. A standard separated bathroom needs 35-40 square feet and runs $7,000-$14,000 depending on tile and fixture choices. Kohler and Moen both make compact lines that work well in tight ADU layouts.
- Mini-split HVAC vs. extending central air: A dedicated mini-split runs $2,500-$5,000 installed and gives the ADU independent climate control. Extending your main home’s central system can cost less if the ductwork run is short, but it creates shared utility headaches and often doesn’t cool a converted garage adequately. In Lauderhill’s humidity, we typically recommend the mini-split.
- Impact-rated windows and doors vs. standard: Standard vinyl windows cost less upfront, but Lauderhill’s location in Broward County means current code requires impact-rated or protected openings for any new conditioned space. PGT and CGI both make aluminum impact-rated lines that look clean and pass inspection without shutters. This isn’t optional here - it’s built into every estimate we write.
- Slab-on-grade flooring vs. raised subfloor: Many Lauderhill garages sit at or slightly below exterior grade with original slabs that show moisture migration. We can seal and tile directly, or build a raised subfloor with vapor barrier and insulation. The raised approach adds $2,000-$4,000 but transforms thermal comfort and prevents mold issues in our wet season.
What Garage Conversion ADU Costs in Lauderhill, FL
Garage conversion ADU projects in Lauderhill typically fall between $30,000 and $80,000. Where you land depends on five factors we assess during your first site visit.

| Structural compliance work | Minimal strapping, roof in good shape | Full roof-to-wall retrofit, beam reinforcement |
| Plumbing relocation | Bathroom/kitchenette near existing lines | New trenching through slab, pump installation |
| Material and fixture grade | Stock cabinetry, solid-surface counters, basic tile | Custom cabinets, Silestone or Caesarstone, designer fixtures |

What Lauderhill Homes Specifically Do to This Job
Lauderhill’s housing reality shapes every garage conversion ADU we build here. The city was largely developed by General Development Corporation from the 1950s through the 1970s as one of South Florida’s first planned communities, and that legacy means we’re working on aging CBS tract homes that predate every modern hurricane code. Nearly every garage we step into has a flat or low-slope roof, original single-pane jalousie windows, and minimal tie-down hardware connecting roof to walls to foundation.
That matters because Broward County enforces current Florida Building Code standards on any permitted conversion, regardless of when the original structure was built. Before we can even frame new interior walls, we often need to install roof-to-wall straps, upgrade the garage door header to handle wind loads, and specify impact-rated replacements for any exterior openings. The permit review is more intensive than what you’d see in a 1990s subdivision, and the inspection rounds reflect that scrutiny.
Lauderhill’s Caribbean-American homeowner community - heavily Jamaican and Haitian - frequently pursues these conversions to accommodate multi-generational families, which means we’re often converting not just standalone garages but carports and Florida rooms that were never designed as conditioned space. Those jobs trigger full FBC compliance reviews on structures originally permitted under 1960s-era codes, adding time but delivering a legal, insurable unit at the end.
The flat terrain and high water table don’t help. Slab-on-grade garages sit in constant hydrostatic pressure, and any plumbing trench through that slab needs proper compaction, drainage, and waterproofing to avoid callbacks after the June-October rainy season. We’ve learned to spec these details conservatively - it’s cheaper to do it right once than to return after a tropical storm.
Homeowners often pair a garage conversion ADU with interior upgrades elsewhere on the property. If you’re already opening walls and running permits, it makes sense to coordinate. Many of our Lauderhill clients also look at Cabinets & Countertops in Lauderhill for the main house kitchen, or Backsplash, Tile & Flooring in Lauderhill to refresh living spaces while the ADU work is underway. As a Home Additions & ADU crew that handles everything from driveway to roofline, we can sequence that work so you’re not juggling separate contractors.
Of course, a garage conversion ADU is often part of a full Home Additions & ADU in Lauderhill plan. We serve Lauderhill and surrounding areas including Lauderdale Lakes, Plantation, Broadview Park, and Fort Lauderdale from our Fort Lauderdale base.

Frequently Asked - Garage Conversion ADU in Lauderhill
Most projects take 10-14 weeks after permit approval, though Lauderhill’s older housing stock often adds 2-3 weeks for structural compliance work that newer cities don’t require. Call (844) 665-0162 and we’ll give you a realistic timeline based on your specific garage and the current Broward County permit queue.
Yes - any conversion of a garage to conditioned living space requires a building permit through Broward County, and because Lauderhill’s pre-1990s homes typically need structural upgrades to meet current Florida Building Code, the permit process is more involved than in newer suburbs. We handle the drawings, submissions, and inspection scheduling as part of our standard project management.
Sometimes, but rarely in Lauderhill’s older homes. Most garages here have a single electrical circuit and no plumbing, so adding a bathroom and kitchenette almost always requires new trenching and panel upgrades. During our free site evaluation, we’ll map your existing utilities and show you exactly what needs to move and what it adds to the cost.
Typically yes - a garage conversion ADU in Lauderhill runs $30,000-$80,000, while detached ADU construction starts around $90,000 and can exceed $220,000. You’re leveraging existing slab, walls, and roof structure, though Lauderhill’s aging stock means more structural prep than in newer cities. For many homeowners, the conversion is the practical entry point into ADU income or family housing.
We warranty our workmanship for one year from final inspection, and all materials carry their manufacturer warranties - windows from PGT or CGI, fixtures from Kohler or Moen, countertops from Silestone or Caesarstone where specified.
