Fast, Reliable Garage Conversion ADU Across Fort Lauderdale
In Fort Lauderdale, canal salt air decides which materials survive and which fail inside five years. We see it on every garage conversion we scope: electrogalvanized roofing fasteners that crumble, window frames that pit, door thresholds that turn to rust scale. A garage conversion ADU here is not the same job as one in Plantation. The flood-zone elevation work, the HVHZ impact glazing, the stainless hardware instead of box-store fasteners. That’s the real cost gap between a Fort Lauderdale conversion and an inland one.
We’re Ellery ADU Studio. Since 2015 we’ve designed, permitted, and built more than 900 ADUs, every one with a written price before work started. If you’re weighing a garage conversion in Rio Vista, Victoria Park, Coral Ridge, or anywhere else in Fort Lauderdale, call (971) 497-2402. We’ll walk your lot, check the slab elevation against the FEMA map, and give you a written scope and price. No verbal ranges, no “call us later.”
Why Ellery ADU Studio Is Fort Lauderdale’s Preferred Garage Conversion ADU Company
Most ADU projects stall in the gap between the designer and the builder. The designer’s drawing assumes one detail, the builder reads it another way, and the homeowner ends up paying for the argument. We don’t have that gap. Ellery ADU Studio is a design-build studio: the drawings, the permit set, and the construction sit inside one contract at one written price. That matters in Fort Lauderdale more than most markets, because the permitting here is unforgiving. Broward County HVHZ code, FEMA AE elevation thresholds, seawall setbacks. A permit set that misses one of those sends you back to the start.
Our Fort Lauderdale work runs through the same team that handles the broader South Florida office, with crews working locally in the city. Nadia Ellery runs the studio. Her standard is written into every contract we send: a documented photo record on every visit, a written scope with a line-item price, and a 365-Day Done Right Promise. If the finished ADU doesn’t match the permitted drawings, we make it right. In writing, before the project starts.
We also give a Free Second Opinion on any written estimate you already have. Bring us a competing bid from a Fort Lauderdale contractor and we’ll go through it line by line, on paper. You’ll see where the price gaps are and what’s missing. That second look has saved many Rio Vista and Las Olas Isles homeowners from signing into a slab-elevation surprise they didn’t see coming.
Our Garage Conversion ADU Services in Fort Lauderdale
A Garage Conversion ADU in Fort Lauderdale usually means one of four approaches. The right one depends on the existing structure, the lot’s flood designation, and whether the garage shares a wall with the main house. Here’s how we handle each across Fort Lauderdale.
Attached Garage Conversion
Attached garages are common in the 1950s through 1970s CBS homes that dominate Victoria Park and Coral Ridge. Because the garage shares the house wall, the conversion typically costs less per square foot than a detached build: one wall, one roof line, one foundation edge to manage. The catch in Fort Lauderdale is the finished floor. If the garage slab sits at grade, and the property is in FEMA Zone AE, you’re looking at either raising the finished floor height or pursuing a variance. We scope that before we touch a drawing.
Detached Garage Conversion
Detached garages are the default ADU target in Rio Vista and the canal-front sections of Las Olas Isles. Many are 1960s CBS structures with decent bones but slab elevations 12 to 18 inches below current flood thresholds. The conversion itself is straightforward; it’s the elevation correction and the HVHZ glazing that make this job real. We’ve done enough of them in Fort Lauderdale that we can tell you within one site visit whether your slab has a path to compliance or whether you’d be better off with a side-yard unit instead.
Carport Conversion
Carport conversions in Fort Lauderdale are rarer than garage jobs, but they come up in the smaller lots of the Middle River Terrace and Sailboat Bend neighborhoods. A carport has no perimeter walls and no enclosure, so the conversion is closer to a small addition. You’re building the envelope from scratch, which means the elevation decision is yours from day one. That’s actually an advantage: you set the finished floor at the right height the first time, no remediation needed.
Garage Partition & Bathroom Add
Some Fort Lauderdale homeowners don’t need a full ADU. They need a working garage plus a small living quarter: install a partition wall, run plumbing, add a bathroom, and keep the front 10 feet for a car and tool bench. We handle this as a Garage Partition & Bathroom Add. It’s the most budget-friendly path to a rental unit or an in-law quarter, and it sidesteps some of the more expensive elevation requirements when the sleeping area stays above the flood line. We quote it the same way as everything else: written price, line items, permitted drawings.

Trusted Brands We Service in Fort Lauderdale
We specify and coordinate prefab systems from Abodu, Cover, and Dvele on Fort Lauderdale garage conversions when the existing slab and setbacks favor a panelized build over stick framing. On canal-front lots, we pair those systems with our own site work: hot-dip galvanized anchors, 316 stainless thresholds, impact-rated windows to meet Broward HVHZ. The panel kit is only as good as the foundation it sits on. For Fort Lauderdale homeowners, we stock the local parts that fail first: stainless fasteners, marine-grade hardware, sealed joint materials. No two-week wait from a depot when we already know what gets eaten by the salt.
Common Garage Conversion ADU Problems We See in Fort Lauderdale Homes
Here’s what we find, across more Fort Lauderdale garage conversions than we can count, on a first walkthrough:
- Electrogalvanized roofing fasteners on the garage’s existing roof. Canal salt spray rusts them through within 3 to 5 years. The roof leaks before the ADU is even finished, and the water damage is inside your new ceiling. We swap them for hot-dip galvanized or stainless as part of every conversion.
- The original garage slab sits below FEMA AE base flood elevation. This is the most expensive surprise in Fort Lauderdale garage conversions, and it’s the reason some bids come in $25,000 apart. Skipping the elevation remediation doesn’t save money; it gets your permit denied. And ‘sunny day’ tidal flooding in Rio Vista and Coral Ridge doesn’t wait for a storm.
- Non-impact-rated windows or doors matched to the main house. They fail Broward County HVHZ inspection. You tear them out, reorder, and pay for drywall repair after the fact. We spec impact-rated glazing from the first drawing, so the inspection is a formality.
- Seawall and rear-yard setbacks consume the entire buildable yard. This one isn’t a materials problem; it’s a geometry problem. On canal-front lots in Rio Vista, Las Olas Isles, and Coral Ridge Isles, the standard rear setback and the seawall setback together can eat the whole rear yard. A traditional detached backyard ADU becomes illegal, and the garage conversion or side-yard unit is the only legal play.
Key Takeaways
- Fort Lauderdale garage conversions are priced by flood zone, slab elevation, and corrosion spec, not just square footage.
- Canal-front lots in Rio Vista and Coral Ridge commonly force garage conversions because rear-yard setbacks kill the detached ADU option.
- Every quote from Ellery ADU Studio is a written line-item price. No verbal ranges, no change orders at the door.
Pricing for Garage Conversion ADU in Fort Lauderdale, FL
A full attached garage conversion in Fort Lauderdale runs $98,000 to $165,000 all-in, drawings through final inspection, when the slab sits at or above the FEMA AE threshold. A detached garage conversion with slab elevation correction runs $145,000 to $240,000, depending on how far below flood elevation the existing slab sits and what the seawall setback does to the buildable area. A garage partition with bathroom add runs $48,000 to $85,000.
- Attached garage conversion: $98,000 - $165,000
- Detached garage conversion, no elevation work: $130,000 - $195,000
- Detached garage conversion, with slab elevation remediation: $145,000 - $240,000
- Garage partition & bathroom add: $48,000 - $85,000
Those bands are Fort Lauderdale numbers: HVHZ glazing, marine-grade hardware, city and county permits, one written price before work begins. The inland version of the same job in Plantation or Sunrise might run 15 to 30 percent less, because it doesn’t carry the corrosion and flood-elevation spec that Fort Lauderdale demands. What we tell our clients: the cheap spec costs more within a decade. The fasteners rust, the windows get replaced, the slab gets remediated at twice the price after the fact. We’d rather you pay for the stainless once. Call (971) 497-2402 and we’ll put a written number on your specific garage.

FAQs - Garage Conversion ADU in Fort Lauderdale
Yes. If your garage slab sits below the FEMA AE base flood elevation for your lot, finished floor elevation must come up to meet the current standard before the permit is approved. Most 1950s-1970s Fort Lauderdale garages sit 8 to 18 inches low. The remediation is a real line item, usually $25,000 to $55,000 depending on access and fill. We confirm the slab height against the county’s latest flood map before we write your quote, so the number you see is the number you pay. Call (971) 497-2402 for a written scope.
Usually yes, you can convert the detached garage. In Rio Vista and the other canal-front neighborhoods of Fort Lauderdale, the rear-yard setback and the seawall setback often consume the entire buildable rear yard, which is exactly why the garage conversion becomes the legal path where a traditional backyard ADU is not. The garage already stands where it stands, and the city’s enforcement focus is on new construction setbacks, not an existing structure you’re renovating internally. The sticking point is the slab elevation and the flood-zone compliance, not the walls. We’ve permitted conversions on Rio Vista lots where the city confirmed the garage position is non-conforming but the conversion itself is approvable. For exact numbers on your lot, call (971) 497-2402 and we’ll pull the flood map and setback schedule while you’re on the phone.
We specify hot-dip galvanized anchor bolts and Simpson Strong-Tie stainless connectors at every structural connection, and we replace any existing electrogalvanized roof fasteners with hot-dip galvanized or 316 stainless. The existing roof on a Fort Lauderdale garage usually carries the original fasteners, and the canal salt spray has been working on them for decades. We replace them during the conversion, not after the first leak. The material cost difference is measurable, and it’s in your written quote as a line item, not hidden inside a round number. Call (971) 497-2402 and we’ll show you the spec sheet.
The difference comes down to three Fort Lauderdale-specific line items. First, many Fort Lauderdale properties sit in FEMA Zone AE, which triggers slab elevation work that inland cities rarely face. Second, Broward County’s HVHZ code requires impact-rated glazing and specific roof-to-wall connections; that spec is stronger than what inland South Florida builds require. Third, the salt air on the canal-front streets means we specify stainless and hot-dip galvanized hardware throughout, where an inland builder can use standard fasteners. Those three add a 15 to 30 percent premium over the same square footage in Plantation or Sunrise. It’s not markup; it’s the cost of building something that doesn’t rot at the anchors. For a written comparison against any other bid, call (971) 497-2402.
Yes, we specify James Hardie siding regularly on canal-front Fort Lauderdale conversions, including in Rio Vista and Coral Ridge. The fiber-cement board handles salt air far better than wood lap siding, which swells and rots within a few seasons of canal spray. The critical part isn’t the board; it’s the fasteners and the flashing behind it. We use stainless fasteners and properly lapped flashing so the siding performs for decades instead of failing at the nail line in five years. The siding itself is a solid choice; the installation spec is where most contractors cut the corner. Our photo record on every visit shows you exactly what went in, fastener by fastener. Call (971) 497-2402 for a written estimate on your conversion.
