What Does a Garage Conversion ADU Cost and Take in Sunrise?
A garage conversion ADU in Sunrise typically runs $30,000-$80,000 and takes 8-14 weeks from permit approval to final inspection, depending on whether you’re keeping the existing slab and roof structure or reconfiguring both. Most Sunrise homeowners we work with in the 33304 area and surrounding neighborhoods are converting single-car garages into studio or one-bedroom units for rental income or multigenerational living. Call (844) 665-0162 and we’ll walk your specific garage and give you a written estimate with no obligation.
How We Convert a Garage to an ADU - Start to Finish
We’ve done enough of these in western Broward to know where the surprises hide. Here’s the actual sequence, with what you’re deciding at each point.
Stage 1: Feasibility and existing conditions review (1-2 weeks)
We measure everything, photograph the existing slab for cracks or settlement, check the roof structure’s load capacity, and verify your electrical panel has room for a subpanel or upgrade. You’ll decide right here whether you’re keeping the garage door opening (converting it to a code-compliant egress window or door) or infilling it entirely with CBS to match the house. We also pull the property’s permit history from Sunrise Building Department to see what was originally approved, since many 1970s-1980s garages in Sunrise were built under older codes that don’t automatically qualify for residential occupancy conversion.
Stage 2: Design and engineering (2-4 weeks)
Our architect draws plans showing the new kitchenette layout, bathroom location, and sleeping area dimensions. If we’re moving plumbing or adding a bathroom where none existed, a plumbing isometric goes to the engineer for review. You’ll choose your material tier here - flooring, cabinets, countertop, fixtures - because these selections affect the mechanical and electrical layouts we submit. For the roof, we determine if the existing flat roof structure can handle insulation upgrades or if we need to sister joists for a proper ceiling assembly.
Stage 3: Permitting (3-6 weeks, variable)
We submit to Sunrise Building Department and coordinate with Broward County if the property sits in a flood zone requiring elevation certificates. Most of Sunrise west of Flamingo Road sits in AE flood zones with base flood elevations that can trigger additional requirements for slab-level conversions. You’ll sign off on any homeowner association notifications if your community requires architectural review - many of the master-planned neighborhoods near Sunset Strip and NW 44th Street do.
Stage 4: Construction (6-10 weeks)
Demo happens first: garage door removal, any interior partition framing, and slab prep for plumbing rough-in if we’re adding a bathroom. Electrical panel upgrade or subpanel installation, then rough plumbing, then insulation and drywall. We install a mini-split HVAC system (most garage ADUs don’t connect to the main house system for code and practical reasons). Flooring, cabinets, countertops, fixtures, and final paint come last. You’ll do two walkthroughs - pre-drywall to confirm outlet and fixture locations, and a punch list before final.
Stage 5: Inspections and certificate of occupancy (1-2 weeks)
Sunrise Building Department inspects rough electrical, rough plumbing, insulation, drywall, and final. We don’t schedule final until we’ve tested every outlet, run the mini-split through a full cycle, and confirmed the egress window meets current IRC opening dimensions. You’ll get the certificate of occupancy only after final approval - and that’s when you can legally occupy or rent the unit.
The Options You’ll Choose Between for Your Garage Conversion ADU
Every choice below affects how the space lives, what it costs, and how soon it pays back. We don’t default you to one path - you choose, we build to spec.
- Keep the existing slab or pour new: Most Sunrise garages have 4-inch slabs without footings, which works for storage but may need reinforcement or a new pour if you’re adding plumbing or the slab has settled. A new 6-inch slab with perimeter footings adds $4,000-$8,000 but eliminates cracking and code headaches.
- Infilled garage door vs. converted opening: Infill with CBS block and stucco to match the house gives a seamless look and better insulation, but costs $2,500-$5,000 more than installing a code-compliant egress door and window in the existing opening. The latter preserves some exterior character if the garage front is visible from the street.
- Kitchenette scale: A wet bar with mini-fridge and microwave ($3,000-$5,000) suits guest use; a full two-burner cooktop with range hood and dishwasher ($6,000-$12,000) qualifies for long-term rental. Your choice triggers different electrical and ventilation requirements.
- Bathroom location and plumbing route: If the garage shares a wall with an existing bathroom, tying into the main drain line is straightforward. Running new plumbing across the slab or through the attic to the opposite side of the house adds $2,000-$6,000 and may require a sewer lift if the garage sits lower than the main line - common in the flatter, wet-soil areas of western Sunrise.
- HVAC approach: A dedicated mini-split ($2,500-$5,000 installed) is standard; extending the main house ductwork rarely works because garage ADUs need independent metering for most rental scenarios, and shared systems create billing and code complications.
- Flooring over concrete: Luxury vinyl plank handles moisture fluctuations well in Sunrise’s humid climate and installs directly over sealed concrete ($4-$8/sq ft). Tile is more durable but colder underfoot and requires crack-isolation membrane over older slabs ($7-$12/sq ft). Engineered hardwood is possible with proper moisture barriers but we don’t recommend it for ground-level conversions near the Everglades edge.
What Garage Conversion ADU Costs in Sunrise, FL
| Project Scope | Price Range |
|---|---|
| Basic garage conversion ADU (existing slab, no plumbing relocation, standard finishes) | $30,000 - $50,000 |
| Mid-range conversion (new bathroom, kitchenette, mini-split, upgraded finishes) | $50,000 - $65,000 |
| Full reconfiguration (new slab, infilled opening, premium kitchen and bath, impact-rated openings) | $65,000 - $80,000 |
Five factors move you up or down this range. First, garage size - a single-car at 240 sq ft versus a two-car at 400+ sq ft changes every material quantity. Second, existing condition - a cracked, unfooted slab from 1978 costs more to remediate than a 1995 pour in good shape. Third, plumbing and electrical distance - tying into existing systems close by versus running new lines across the house. Fourth, material grade - standard LVP and stock cabinets versus tile, quartz, and custom millwork. Fifth, permit scope - a straightforward change of occupancy versus a full structural review triggered by recertification flags or flood zone requirements.
Our written estimates include demolition, rough and finish carpentry, plumbing and electrical rough-in and finish, insulation, drywall, flooring, cabinets, countertops, fixtures, paint, and final cleanup. They don’t include permit fees (typically $800-$2,000 in Sunrise), architectural or engineering drawings if required ($1,500-$4,000), or HOA application fees. We line-item everything so you see where your money goes before we start.
What Sunrise Homes Specifically Bring to This Job
Sunrise’s housing stock shapes every garage conversion ADU we bid here. The city was substantially built out in the 1970s and 1980s as a master-planned suburban community, and that era’s construction dominates the single-family neighborhoods where garage conversions make sense. We regularly work on CBS homes with 4-inch garage slabs poured without footings, flat roofs with scuppers instead of gutters, and electrical panels that max out at 100 amps - all of which need addressing before a conversion can qualify for occupancy.
The 40-year recertification cycle is the bigger factor. Broward County’s mandatory structural recertification program has hit full stride for Sunrise’s 1980s buildings, and we’ve seen properties along the older condo corridors near Sunset Strip and NW 44th Street where the main structure’s recertification revealed spalled concrete or corroded rebar. If your home is part of this cycle, any ADU permit application gets reviewed in that context - the city won’t approve a garage conversion if the primary structure has open code violations. We check this upfront so you’re not surprised six weeks into permitting.
Climate matters too. Sunrise sits inland adjacent to the Everglades water conservation areas, and the seasonal high water table complicates any below-grade work. Garage slabs here often show moisture migration through the concrete, which means we spec vapor barriers and moisture-resistant materials as standard, not upgrades. The wet season’s afternoon thunderstorms compress exterior work windows from June through October, so we schedule any roof or opening modifications for drier months when possible.
Many homeowners doing a garage conversion ADU as part of a full Home Additions & ADU in Sunrise project also ask us about interior finishes - we often coordinate with our Cabinets & Countertops in Sunrise crew and Backsplash, Tile & Flooring in Sunrise specialists to match the ADU finishes to a concurrent kitchen or bath remodel in the main house. And if you’re comparing this to a detached build, our Home Additions & ADU service hub covers the full range of expansion options we offer across Sunrise and nearby communities.

Frequently Asked - Garage Conversion ADU in Sunrise
From permit approval to certificate of occupancy, expect 8-14 weeks. Permitting itself adds 3-6 weeks depending on whether Sunrise Building Department requests engineering review or flood zone documentation. Call (844) 665-0162 and we can give you a tighter timeline after seeing your garage and pulling its permit history.
Yes - a change of occupancy permit is required, plus electrical, plumbing, and mechanical permits if you’re adding those systems. Sunrise also requires compliance with current Florida Building Code and may reference Broward County’s 40-year recertification status for older structures. We handle all permit submissions as part of our process.
You can, but the result is limited. A garage conversion ADU without plumbing is legally a bedroom or office, not a dwelling unit - no kitchenette, no bathroom, no separate rental. Most Sunrise homeowners want at least a wet bar and half-bath, which requires new plumbing. Electrical almost always needs upgrading for code-compliant outlets, lighting, and HVAC.
The lowest-cost path keeps the existing slab, preserves the garage door opening with an egress door and window, adds a wet bar instead of a full kitchen, and uses a shared bathroom access or compact half-bath. That typically hits the $30,000-$40,000 range. Every addition - full kitchen, new slab, dedicated bathroom, premium finishes - moves you up. We’ll show you exactly where each dollar goes.
We warranty our workmanship for one year from certificate of occupancy. Manufacturer warranties apply to specific products - cabinets, flooring, fixtures, mini-split units - and range from 5 years to lifetime depending on the brand you select. We register all warranties in your name and provide documentation at final walkthrough.
