Garage Conversion ADU in North Andrews Gardens: What It Costs and How Long It Takes
A garage conversion ADU in North Andrews Gardens transforms your existing garage into a permitted, habitable living space - typically a studio, one-bedroom unit, or in-law suite - without expanding your home’s footprint. Most projects we handle in this area run 8 to 14 weeks from permit approval to final inspection, with costs ranging from $30,000 to $80,000 depending on structural condition and finish level.

How We Approach a Garage Conversion ADU in North Andrews Gardens
Every garage conversion ADU follows a five-stage sequence. Knowing the order helps you plan decisions and anticipate inspections, especially here in unincorporated Broward County where the workflow differs from nearby Oakland Park or Fort Lauderdale.
Stage 1: Existing Conditions & Code Assessment (1-2 weeks)
We start by documenting what you have. Our team measures the garage footprint, checks slab elevation and drainage slope, tests the existing electrical panel capacity, and identifies whether the garage shares a roofline with the main house or sits under a separate structure. In North Andrews Gardens, we also verify whether prior unpermitted work exists - common in homes built during the 1960s and 1970s - since any new permit triggers full county code compliance. You’ll decide at this stage whether you want a full architectural survey or if existing county records suffice.
Stage 2: Design & Broward County Permitting (4-8 weeks)
Because North Andrews Gardens is unincorporated, all permits route through the Broward County Building and Code Compliance Division, not a city office. We submit structural plans showing the conversion meets residential egress, ceiling height, and HVAC requirements. If your garage slab sits below the water table or shows moisture intrusion - typical for this flat, low-elevation coastal plain - we specify vapor barriers and drainage improvements now. Your decisions here: window placement and size, whether to add a kitchenette or full bath, and whether to match existing CBS stucco or upgrade to a contrasting finish.
Stage 3: Structural & Utility Rough-In (2-3 weeks)
Demolition is limited in a conversion, but we often need to cut the slab for plumbing drains, reinforce the roof structure for insulation and ceiling loads, and upgrade the electrical service to support independent metering if you’re pursuing a full ADU rental. In North Andrews Gardens homes with original flat or low-slope roofs, we frequently sister new rafters or add rigid insulation to meet current HVHZ standards. You’ll choose your HVAC approach at this point: mini-split, extension of the main house system, or independent package unit.
Stage 4: Insulation, Drywall, and Finish Installation (3-4 weeks)
We install moisture-resistant insulation rated for South Florida’s humidity, then hang drywall, run flooring, and trim out electrical and plumbing fixtures. This is where material choices show up in the final look and cost. Many homeowners in North Andrews Gardens pair their garage conversion ADU with interior upgrades elsewhere in the home - Cabinets & Countertops in North Andrews Gardens is a common parallel project when the main kitchen also needs refreshing.
Stage 5: County Inspection & Final Walkthrough (1-2 weeks)
Broward County inspectors verify structural, electrical, plumbing, and fire safety compliance. Because this is an ADU, they also confirm independent egress and habitability standards. We schedule inspections in sequence and remain on-site to address any punch-list items. Final sign-off typically takes two visits if the project is clean, longer if prior unpermitted work surfaces.
The Choices That Shape Your Garage Conversion ADU
Every decision below affects cost, durability, and how the space feels to live in. We don’t default you to one option - you choose based on how you’ll use the unit.
- Slab treatment: Seal and polish the existing concrete, or pour a new floating floor with moisture barrier and insulation. The existing slab in older North Andrews Gardens garages often lacks proper vapor protection; sealing is cheaper short-term but can fail if groundwater rises. A new floating floor adds $3,000-$6,000 but eliminates moisture issues permanently.
- Kitchenette vs. wet bar: A full kitchenette with cooktop, sink, and compact refrigerator requires plumbing rough-in and county health inspection, adding $4,500-$9,000. A wet bar with sink and mini-fridge is simpler and suits guest use or short-term rental where cooking is minimal.
- Bath configuration: Three-quarter bath (shower, toilet, sink) fits most garage footprints without moving exterior walls. Full tub adds space requirements and water heater capacity. For tight conversions, a wall-hung toilet and corner shower from Kohler or Moen reclaim square footage without feeling cramped.
- Flooring material: Luxury vinyl plank handles moisture and installs fast; porcelain tile costs more but lasts decades in a rental unit. Engineered wood looks warm but requires strict humidity control in South Florida’s wet season.
- Exterior integration: Match existing stucco and trim, or define the ADU with distinct siding and a separate entry courtyard. Many homeowners in North Andrews Gardens prefer visual separation when the unit will rent on a long-term basis.
Homeowners often coordinate the interior finishes of a garage conversion ADU with adjacent spaces - Backsplash, Tile & Flooring in North Andrews Gardens can unify the main house and converted unit when both projects run together.
What Garage Conversion ADU Costs in North Andrews Gardens, FL
| Component | Typical Range |
|---|---|
| Garage Conversion ADU (total project) | $30,000 - $80,000 |
| Structural reinforcement & slab work | $4,000 - $12,000 |
| Plumbing rough-in & fixtures | $3,500 - $9,000 |
| Electrical service upgrade | $2,500 - $7,000 |
| HVAC (mini-split system) | $3,000 - $6,500 |
| Permits & Broward County fees | $1,200 - $3,500 |
| Finish materials & labor | $12,000 - $35,000 |
Five variables push your project toward the low or high end of that $30,000-$80,000 range:
1. Existing garage condition. A structurally sound, dry garage with adequate electrical panel capacity starts closer to $30,000. Rotting roof decking, insufficient slab thickness, or a panel that needs full replacement adds $8,000-$15,000 before finishes begin.
2. Plumbing relocation distance. If your garage sits far from the main sewer line or requires a sewage ejector pump due to flat grade, plumbing costs jump. North Andrews Gardens’ low elevation and high water table make gravity drainage a real design constraint.
3. Material grade. Builder-grade finishes and standard appliances keep costs controlled. Quartz countertops from Silestone or Caesarstone, impact-rated windows, and custom cabinetry move the finish budget upward but also improve rental income potential and insurance credits.
4. Permit scope and code surprises. Because unpermitted prior work triggers full compliance, we sometimes discover mid-project that the existing roof structure or electrical service must be brought to current code across the entire home, not just the garage. We price contingency into every estimate, but this variable is the hardest to predict without a thorough pre-permit assessment.
5. Independent metering and ADU classification. A fully permitted, independently metered ADU rents at market rate and adds property value. A simpler “accessory living area” without separate utilities costs less but offers fewer legal use options. We explain both paths during your estimate so you choose deliberately.
Our written estimates itemize labor, materials, permits, and contingency. They do not include furniture, window treatments, or landscaping beyond the immediate work area.
What North Andrews Gardens Homes Specifically Do to This Job
North Andrews Gardens sits in unincorporated Broward County, and that single fact reshapes every garage conversion ADU we build here. Unlike neighboring Oakland Park or Wilton Manors, where municipal building departments handle permits locally, all North Andrews Gardens construction flows through the Broward County Building and Code Compliance Division. County inspectors follow a different schedule, different checklists, and different communication protocols than city crews. We know the specific county inspectors who cover this ZIP code and their typical lead times, which helps us set realistic expectations.
The housing stock matters too. Most homes here are single-story CBS structures built between the late 1950s and 1970s, many with flat roofs and original electrical panels that predate modern load requirements. When we convert a garage in North Andrews Gardens, we’re often upgrading the main service panel not because the garage demands it, but because the county requires the entire electrical system to meet current code once we pull a new permit. The same applies to wind-mitigation: post-Hurricane Andrew revisions phased in since 1994 mean older roof-to-wall connections frequently need reinforcement, especially if the garage shares a roofline with the main house.
Water is the other constant. The coastal plain here holds groundwater just a few feet below grade, so slab moisture and drainage dominate our early conversations. We specify vapor barriers and perimeter drainage as standard, not upgrades, because skipping them guarantees callback problems during summer thunderstorm season.
Perhaps the most specific local wrinkle: unpermitted garage conversions from the 1970s and 1980s are common in this neighborhood, and many long-time homeowners don’t realize those old conversions trigger full county code compliance the moment a licensed contractor pulls a new permit. We’ve seen projects where a simple “update” became a full gut because the existing framing, electrical, and egress never met any code at all. We catch this in Stage 1 so you’re not surprised in Stage 4.

Frequently Asked - Garage Conversion ADU in North Andrews Gardens
Most projects take 8 to 14 weeks after permit approval, with Broward County permitting itself adding 4 to 8 weeks. Total timeline from signed contract to certificate of occupancy typically runs 4 to 5 months. Call (844) 665-0162 and we’ll review your specific garage’s condition to narrow that range.
Yes - and because North Andrews Gardens is unincorporated, the permit comes from Broward County, not a city office. Any permitted work also triggers county code compliance for existing, unpermitted conditions in the same structure. We handle the application, plans, and inspection scheduling as part of our project management.
County code requires habitable space to meet insulation, egress, and structural standards that a standard garage door cannot satisfy. We remove the overhead door, frame and infill the opening with CBS or framed wall matching your home, and install a proper entry door and windows. The result looks intentional, not like a converted garage.
A garage conversion ADU in North Andrews Gardens typically costs $30,000-$80,000, while a detached ADU runs $90,000-$220,000. The existing slab and roof structure in a garage save significant foundation and framing costs. However, if your garage needs extensive structural repair or your lot allows a simple detached unit with minimal utility runs, the gap narrows. We price both paths when it makes sense.
We warranty our workmanship for one year from final inspection. Manufacturer warranties apply to specific products - Kohler fixtures, Moen valves, Silestone or Caesarstone surfaces - and range from limited lifetime to 10 years depending on the item. We register all warranties in your name and provide documentation at closing. For questions about coverage on a specific product, call (844) 665-0162.
