ADU in Fort Lauderdale, FL
ADU Design & Permitting in Fort Lauderdale starts with flood-zone verification and a hard look at your existing slab elevation because most 1950s-1970s CBS homes in Victoria Park, Rio Vista, and Coral Ridge sit below current FEMA AE thresholds. Our design-build studio writes a single contract for drawings, permits, and construction so one team owns the outcome from site assessment through final inspection. That matters in a city where canals, seawalls, and High Velocity Hurricane Zone code add layers most ADU guides never mention. Call (971) 497-2402 and we’ll put the full picture on paper before any work starts.
Why Fort Lauderdale Homes Are Different
Fort Lauderdale’s 165+ miles of navigable canals are the reason an ADU here rarely behaves like one in Plantation or Sunrise. A waterfront lot in Rio Vista or Las Olas Isles has to satisfy Broward County seawall setbacks, FEMA base flood elevation requirements, and the city’s standard rear-yard setback at the same time. On many canal-front parcels, the seawall setback and rear-yard setback together consume the entire buildable back yard, which pushes projects toward garage conversions or side-yard units whether the owner wanted that or not.
The housing stock compounds it. Most homes in Coral Ridge and Victoria Park are concrete block structures from the 1950s through 1970s on lots between 6,000 and 8,500 square feet. Their detached garages and pool cabanas look like obvious conversion targets, but the original slabs almost universally sit below current flood elevation requirements. Elevating a finished floor 8 to 10 feet above grade changes the structural and mechanical scope of a conversion before a single drawing is stamped. And every ADU in Broward County falls under Florida’s High Velocity Hurricane Zone code: impact-rated glazing, prescriptive roof-to-wall connections, and hardware that exceeds what builders use anywhere north of Palm Beach County.
Our Main Fort Lauderdale Services
Most Fort Lauderdale homeowners contact us about one of two projects: converting an existing garage into a rental unit, or building a new detached ADU where the lot allows it. Each has its own page with full local detail.
Garage Conversion ADU in Fort Lauderdale
Converting a 1950s-1970s detached garage is often the fastest path to an ADU in Fort Lauderdale because the structure and roof already exist. The catch is flood elevation: nearly all original garage slabs in Victoria Park, Coral Ridge, and Rio Vista sit below current FEMA AE thresholds and need remediation before Broward County will sign off on a permit. There’s no shortcut around that. The full scope, including drawings, flood mitigation, and construction, lives on the dedicated page: Garage Conversion ADU in Fort Lauderdale.
New Detached ADU in Fort Lauderdale
A new detached ADU on a Fort Lauderdale lot works where setbacks allow it. On canal-front parcels in Las Olas Isles or Coral Ridge Isles, the seawall setback combined with the rear-yard setback sometimes eliminates the buildable rear yard entirely, which means the ADU has to move to the side yard or become a garage conversion instead. On interior lots with enough clearance, a new build gives you clean control over finished floor elevation from day one. Details are on the dedicated page: New Detached ADU in Fort Lauderdale.

ADU Design & Permitting in Fort Lauderdale
ADU Design & Permitting in Fort Lauderdale is the service that keeps a project from stalling at the building department. On a 1950s CBS home in Rio Vista or Victoria Park, the permit set has to prove finished floor elevation meets FEMA AE requirements, the roof-to-wall connections meet High Velocity Hurricane Zone code, and the seawall setback is untouched. We produce that permit set and the construction under one contract, so the drawings and the build are owned by the same team. ADU Design & Permitting is where every Ellery project starts.
Site Assessment
Signs you need it
Your lot backs up to a canal, your survey shows an existing slab below flood elevation, or your side yard is the only buildable space left.
What it costs in Fort Lauderdale
Site assessment in Fort Lauderdale ranges from $1,450 to $3,900 depending on whether we need a topographical survey and FEMA elevation certificate.
How we do it
We pull the survey, field-verify slab heights, map the seawall and rear-yard setbacks against your parcel, and hand you a written go/no-go summary with the specific numbers that will drive the permit set.
ADU Design & Blueprints
Signs you need it
You know what you want to build but you don’t have a signed, sealed drawing set that Broward County will actually accept.
What it costs in Fort Lauderdale
ADU design and blueprints in Fort Lauderdale run $4,500 to $9,800 for drawings, structural engineering, and HVHZ detailing.
How we do it
We draft the full set, run the structural calcs for flood elevation and wind load, and hand you a permit-ready package rather than a concept sketch.
Permit Application
Signs you need it
You’ve already had a design done and now need someone to shepherd it through Broward County’s plan review without a cycle of corrections.
What it costs in Fort Lauderdale
Permit application runs $1,200 to $3,200 depending on whether we file for one ADU or also handle the flood-zone and seawall documentation.
How we do it
We file the drawings, attach the elevation certificate and HVHZ compliance sheets, and answer plan-review comments until the permit is issued.
HOA & Zoning Compliance
Signs you need it
Your neighborhood has an HOA with architectural review or your lot sits in a flood zone where the rear setback and seawall rule collide.
What it costs in Fort Lauderdale
HOA and zoning compliance in Fort Lauderdale runs $600 to $1,900 for the documentation packet and representation at one review meeting.
How we do it
We read the HOA covenants and the city’s zoning code against your survey, then produce the compliance letter and supporting exhibits your review board wants.
What ADU Design & Permitting Costs in Fort Lauderdale
| Item | Typical range in Fort Lauderdale |
|---|---|
| Site Assessment and Elevation Certificate | $1,450 - $3,900 |
| ADU Design & Blueprints | $4,500 - $9,800 |
| Permit Application & Filing | $1,200 - $3,200 |
Can I permit an ADU on a Fort Lauderdale canal lot?
Yes, but the rear-yard setback plus the Broward County seawall setback can eliminate the entire back yard on narrow canal-front parcels, forcing a garage conversion or side-yard unit instead. We flag this during the site assessment.
Does my Fort Lauderdale ADU need flood elevation paperwork?
If your parcel is in FEMA Zone AE, yes. Most 1950s-1970s slabs in Victoria Park and Coral Ridge sit below current thresholds, and Broward County requires a finished floor 8 to 10 feet above grade. Call (971) 497-2402 for specifics.
Junior ADU & Interior Conversion in Fort Lauderdale
A Junior ADU or interior conversion in Fort Lauderdale means carving a rental-ready unit out of space you already own: an attached garage, a master suite wing, or a bonus room. The value here is that you avoid the rear-yard setback problem entirely and you keep the existing roofline, which saves real money under HVHZ code. The constraint is elevation: any converted space with a finished floor below the FEMA AE threshold has to be addressed in the permit set. Junior ADU & Interior Conversion is the service we run for exactly these projects.
Above-Garage ADU
Signs you need it
You have an attached garage with enough ceiling height to gain a second-floor unit without touching the slab.
What it costs in Fort Lauderdale
An above-garage ADU in Fort Lauderdale runs $110,000 to $190,000 including drawings, structural framing, and a permit-ready finished floor elevation.
How we do it
We verify the garage’s load path and roof framing, design a unit above the existing envelope, and write one contract that covers drawings through final paint.
Room-to-ADU Conversion
Signs you need it
You have a master suite wing, bonus room, or attached cabana with its own entrance or room for one that you want turned into a rentable unit.
What it costs in Fort Lauderdale
A room-to-ADU conversion in Fort Lauderdale costs $75,000 to $130,000 depending on whether you add a kitchenette and its plumbing lateral.
How we do it
We establish the fire separation wall, add the kitchenette and its drain, upgrade the panel if needed, and file the permit set under Broward County’s interior-conversion rules.
Interior JADU
Signs you need it
You want the least expensive permitted rental possible without changing the footprint of your home or touching the slab.
What it costs in Fort Lauderdale
An interior JADU in Fort Lauderdale runs $55,000 to $95,000 all-in from drawings through final inspection.
How we do it
We partition off part of the main house, add a kitchenette and egress, and file the JADU paperwork under Florida’s accessory dwelling rules.
What Junior ADU & Interior Conversion Costs in Fort Lauderdale
| Item | Typical range in Fort Lauderdale |
|---|---|
| Above-Garage ADU | $110,000 - $190,000 |
| Room-to-ADU Conversion | $75,000 - $130,000 |
| Interior JADU | $55,000 - $95,000 |
Is a JADU legal in Fort Lauderdale as a rental?
Yes, Florida and Broward County permit JADUs as accessory dwellings, but the unit must have its own kitchenette, a code-compliant egress, and a permit. We file the paperwork as part of the design contract.
Will my interior conversion trigger a flood elevation review?
It depends on the finished floor elevation and your FEMA zone. If the space sits below the AE threshold, Broward County requires documentation showing what mitigation is needed. Call (971) 497-2402 for an exact read.
ADU Site Prep & Utilities in Fort Lauderdale
Site prep and utilities in Fort Lauderdale are where the lot itself decides the budget. A 1950s CBS home in Coral Ridge typically has a 100-amp panel that cannot serve an ADU, a cast-iron plumbing lateral that predates current code, and a yard that slopes toward the canal or the street at exactly the wrong angle for drainage. We fix all of that under the same written price as the build. ADU Site Prep & Utilities is the service that runs from first cut to utility tie-in.
Foundation & Grading
Signs you need it
Your lot sits in FEMA Zone AE and the finished floor will need to be raised above the existing slab, or your yard lacks positive drainage away from the house.
What it costs in Fort Lauderdale
Foundation and grading in Fort Lauderdale runs $14,000 to $41,000 depending on fill volume, compaction, and the finished floor height the permit requires, and $35 to $70 per square foot for the slab itself.
How we do it
We cut and compact fill to the height the elevation certificate demands, pour a slab above flood grade, and grade the surrounding yard for positive drainage.
Electrical Panel Upgrade
Signs you need it
Your current panel is 100 or 125 amps and your ADU needs a subpanel, EV charging, and a dedicated HVAC circuit.
What it costs in Fort Lauderdale
A panel upgrade for an ADU in Fort Lauderdale runs $2,500 to $5,000 for a 200-amp replacement, and $60 to $120 per linear foot for a new underground service feeder.
How we do it
We replace the main panel, pull a new feeder to the ADU location, and wire the unit’s subpanel and circuits under the same permit set as the build.
Plumbing Lateral
Signs you need it
Your existing cast-iron lateral is cracked or undersized, or the ADU sits far enough from the main sewer line that it needs its own drain run.
What it costs in Fort Lauderdale
A plumbing lateral for an ADU in Fort Lauderdale runs $45 to $80 per linear foot, and a dedicated sewer tap costs $3,500 to $7,500 depending on depth and access.
How we do it
We locate the main, cut the connection, run a new PVC lateral to the ADU’s drain point, and pressure-test the line before inspection.
Landscaping & Hardscape
Signs you need it
You need a level path from the main house to the ADU, or the grading work left the yard bare and the HOA requires restoration within 90 days.
What it costs in Fort Lauderdale
Landscaping and hardscape for an ADU site in Fort Lauderdale runs $15 to $35 per square foot for plantings, and $4,000 to $12,000 for a paver walkway and small patio.
How we do it
We return the disturbed areas to grade, lay the walkway, plant native ground cover, and photograph everything before the final walkthrough.
What ADU Site Prep & Utilities Costs in Fort Lauderdale
| Item | Typical range in Fort Lauderdale |
|---|---|
| Foundation & Grading (slab) | $35 - $70 / sq ft |
| Electrical Panel Upgrade (200A) | $2,500 - $5,000 |
| Plumbing Lateral & Sewer Tap | $45 - $80 / linear ft + $3,500 - $7,500 tap |
Do I need a new sewer tap for my Fort Lauderdale ADU?
Only if the existing lateral is undersized or the ADU sits too far to tie in practically. We field-verify the line and show you the numbers before you commit. Call (971) 497-2402.
Will my panel handle an ADU and a heat pump in Fort Lauderdale?
Most 1950s-1970s panels in Coral Ridge and Victoria Park will not. We quote the panel upgrade as a line item inside the written site-prep price, not as a surprise after the fact.

FAQs About ADU in Fort Lauderdale
Plan review at Broward County typically runs 4 to 8 weeks for a complete permit set, but flood-zone comments and seawall documentation can add a cycle. We file the drawings with the elevation certificate and HVHZ compliance sheets attached from day one, which keeps the review on schedule. Call (971) 497-2402 for a current read on wait times.
If your neighborhood has an HOA with architectural review, yes. We produce the compliance packet, attend the review meeting, and file the zoning exhibit at the same time we submit the city permit, so the two tracks don’t drift apart.
Yes, we design for that reality. Finished floor elevation, drainage, and mechanical placement are all set to the flood zone, not to the current grade. The site assessment tells us exactly how high the finished floor needs to sit, and that number goes in the written quote.
