Garage Conversion ADU in West Park - Scope, Timeline, and What You’ll Pay
Garage Conversion ADU in West Park transforms an existing attached or detached garage into a permitted, habitable living unit with its own kitchenette, bathroom, sleeping area, and separate entrance. Most conversions we complete in West Park run 10 to 16 weeks from permit approval to final inspection, with costs typically falling between $30,000 and $80,000 depending on what’s already there and what has to be added. Call (844) 665-0162 and we’ll walk your specific garage with you, same week.
How We Convert a Garage to an ADU - Start to Finish
Every Garage Conversion ADU follows a five-stage sequence. We’ve refined this through builds across Broward County, and the timeline holds steady unless we hit legacy permitting issues specific to West Park’s pre-2005 construction history.
Stage 1: Feasibility and existing conditions review (1-2 weeks)
We measure your garage slab, roof structure, and electrical panel capacity. You’ll decide at this stage whether you want a full kitchen or a kitchenette, whether the bathroom needs a shower or just a wet bath, and whether you’re keeping the existing garage door opening as your ADU entrance or framing in a conventional doorway. We pull preliminary records from West Park’s building department and Broward County archives to flag any unpermitted prior work that could stall your permit.
Stage 2: Design, engineering, and permit submission (3-6 weeks)
Our draftsman produces plans showing the conversion layout, structural modifications, and MEP routing. If your garage has a flat or low-slope roof typical of 33023 homes, we often need a Florida-licensed engineer to certify that the existing roof diaphragm meets current wind-load requirements after we cut openings for windows or a new entry door. You’ll choose your material package at this stage - flooring, cabinetry, countertop, fixtures - so we can spec loads and rough-in locations precisely. Permit submission goes to West Park’s building department, and we handle all plan corrections.
Stage 3: Demolition and rough construction (2-3 weeks)
We strip the garage interior to studs, remove the overhead door and track, and frame new interior partitions, window openings, and the rated firewall separation from your main house if code requires it. For detached garages in West Park’s older neighborhoods, we frequently have to address slab settlement cracks or poor drainage around the perimeter before we can seal new flooring. Electrical rough-in, plumbing rough-in, and any HVAC ducting or mini-split lines happen here.
Stage 4: Insulation, drywall, and finishes (3-4 weeks)
We insulate to Florida Energy Code standards - critical in a space that was never conditioned - then hang drywall, install flooring, and run trim. Cabinetry goes in, followed by countertops and backsplash. For Cabinets & Countertops in West Park, we typically spec KraftMaid or Wellborn cabinetry paired with a Cambria quartz surface in ADU kitchenettes because both hold up to tenant turnover and resist the humidity that builds in converted garages without perfect air sealing.
Stage 5: Final inspections and certificate of occupancy (1-2 weeks)
West Park’s building department inspects structural, electrical, plumbing, mechanical, and energy code compliance. If your garage conversion was part of a full Home Additions & ADU in West Park project, we coordinate final inspections across all scopes simultaneously. We don’t consider the job complete until you have a CO in hand and we’ve walked you through every system.
The Spec Choices That Shape Your Garage Conversion ADU
These decisions come up on every Garage Conversion ADU we build in West Park. The right choice depends on how you’ll use the space - long-term rental, family housing, or occasional guest use - and what the existing structure can accommodate without excessive rework.
- Kitchenette vs. full kitchen: A kitchenette with a two-burner cooktop, under-counter fridge, and single-bowl sink runs $4,000-$8,000 less than a full kitchen with range, full-size refrigerator, and dishwasher. For rental ADUs under 400 square feet, the kitchenette is usually sufficient and easier to permit under Broward County’s ADU guidelines. Full kitchens make sense when the garage is oversized or when the ADU will house family long-term.
- Wet bath vs. full bathroom: A wet bath - shower, toilet, and sink in a fully waterproofed room with a floor drain - fits into 30-35 square feet and avoids the cost of a separate shower enclosure. Full bathrooms with a tiled shower stall or tub need 45-55 square feet and add $3,500-$6,000 in material and labor. In West Park’s compact 1950s-1970s garages, the wet bath often wins on spatial grounds alone.
- Mini-split HVAC vs. extending central air: A ductless mini-split with its own condenser costs $3,500-$6,500 installed and operates independently from your main house system. Extending existing ductwork only works if your current unit has sufficient capacity, which many 60-100 amp homes in 33023 do not. We calculate load manually; oversizing a mini-split is as wasteful as undersizing it.
- Slab-on-grade flooring vs. raised subfloor: If your garage slab is level, dry, and structurally sound, we can apply a moisture barrier and lay luxury vinyl plank or tile directly. That’s the economical path. If the slab has settlement cracks or chronic dampness - common in West Park’s flat, poorly draining sites - we build a raised subfloor with sleepers and rigid insulation, adding $2,500-$4,500 but solving moisture and thermal bridging permanently.
- Standard entry door vs. impact-rated: West Park lies in Broward County’s high-velocity hurricane zone. Any new exterior door must be impact-rated or protected with approved shutters. Impact-rated doors add $400-$900 per opening but satisfy code without secondary protection. We source these through our window and door partnerships with Andersen, Pella, and Jeld-Wen.

A written estimate from Groundwork Construction Co. includes all labor, materials, permit fees, and inspections for the conversion scope we define together. It does not include separate costs for main-house electrical service upgrades, well or septic modifications, or HOA architectural review fees if your West Park neighborhood has them. We flag these potential add-ons during feasibility so you’re not surprised.

What West Park Homes Specifically Do to This Job
West Park only incorporated in 2005. That single fact reshapes nearly every Garage Conversion ADU we take on here.
Before incorporation, the area was unincorporated Broward County, and county permitting enforcement for residential alterations was historically uneven. We routinely open walls in 33023 garages and find conversions, additions, or re-roofs completed without permits or final inspections - sometimes decades ago, sometimes more recently. When we submit a new Garage Conversion ADU permit to West Park’s building department, those unrecorded modifications surface. The city cannot issue a new permit until the old work is brought into compliance with current Florida Building Code wind and flood standards. That means additional engineering, additional demolition, and additional cost that a homeowner in a city with continuous municipal oversight rarely faces.
The housing stock compounds this. Most 33023 homes are 1950s-1970s CBS construction on slab-on-grade foundations, with original electrical panels at 60-100 amps and roof systems that have cycled through multiple repairs. Flat and low-slope roofs common in this era require careful detailing when we add windows or change the envelope geometry. The near-surface water table and poor natural drainage mean slab moisture is a recurring issue; we test with calcium chloride kits before specifying any flooring system.
We’ve learned to build time and budget contingency into every West Park Garage Conversion ADU proposal. The homeowners who get through smoothest are the ones who let us run a full records search and slab assessment before we price - not after.

Frequently Asked - Garage Conversion ADU in West Park
Most conversions take 10 to 16 weeks from permit approval to certificate of occupancy, with permit processing adding 3 to 6 weeks on top. Call (844) 665-0162 for a timeline based on your specific garage and any legacy permitting issues we uncover.
Yes, absolutely. West Park’s building department requires permits for structural, electrical, plumbing, mechanical, and energy code compliance. Because many 33023 properties have unpermitted prior work, we often need to resolve old violations before the new permit can issue. We handle this remediation as part of our process.
You can avoid relocating existing mains, but you’ll still need new branch lines and circuits for the ADU’s kitchenette, bathroom, and HVAC. The existing 60-100 amp panels common in West Park’s older homes usually cannot support the added load without an upgrade or a subpanel. We determine this during feasibility and price both scenarios.
A basic single-car conversion with kitchenette, wet bath, mini-split, and LVP flooring starts around $30,000 in West Park. That assumes a sound slab, no roof work, and clean permitting history. Each added system or remediation need moves the number up. We provide itemized estimates so you see exactly where your money goes.
Groundwork Construction Co. stands behind our workmanship with a written warranty on labor, and the materials we install carry their own manufacturer warranties - KraftMaid cabinetry, Cambria countertops, and the mini-split or HVAC equipment you select.
