Fort Lauderdale's ADU ordinance is more restrictive than most Florida cities — a hard 600 sq ft cap, a maximum of 1 bedroom and 1 bathroom, required owner occupancy, and a full prohibition on short-term rentals under 30 days. If those constraints work for your property, the long-term rental market is strong: 1-bed ADUs near Fort Lauderdale's marine, financial, and airport employment centers command $1,500–$2,000/month.
ADUs in Fort Lauderdale are governed by ULDR Section 47-19.2. All permits flow through the LauderBuild portal. Both detached and garage-conversion forms are available under the ordinance.
Under Florida SB 184 (2025), state law creates a floor of 1,000 sq ft for ADU size minimums — Fort Lauderdale's 600 sq ft cap is a maximum, not a minimum, so these don't conflict. However, SB 184 compliance details and any local updates should be verified directly with Development Services.
Key constraints to understand before designing
Fort Lauderdale ADUs are limited to 600 sq ft (or 49% of primary — whichever is smaller), 1 bedroom / 1 bathroom maximum, owner-occupancy required, and STRs under 30 days are prohibited. An Annual Certificate of Use is required to legally rent the unit. Verify all current requirements with Fort Lauderdale Development Services before committing to plans.

1. Fort Lauderdale ADU Zoning Rules (ULDR §47-19.2)
Reference document: ULDR Section 47-19.2
Fort Lauderdale's ADU rules are codified in its Unified Land Development Regulations at Section 47-19.2. Always reference this section number when communicating with Development Services or your architect. Verify current text at library.municode.com/fl/fort_lauderdale.
ADU Eligibility Requirements
STR Prohibition — Important
Fort Lauderdale explicitly prohibits short-term rentals (under 30 days) in residential zones. Do not build a Fort Lauderdale ADU with the intention of listing it on Airbnb or VRBO — this is not permitted. Build your rental income model around long-term tenants only.
📞 Confirm Parcel Eligibility Before Designing
Historic overlays, flood zones, and parcel-specific constraints can affect ADU eligibility beyond the baseline ULDR rules. Contact Fort Lauderdale Development Services before hiring an architect to confirm your parcel's specific eligibility and setback requirements.
2. The 7-Step LauderBuild Permit Process
All Fort Lauderdale building permits are submitted through the LauderBuild portal. Fort Lauderdale is in Broward County's High Velocity Hurricane Zone — all construction must meet HVHZ wind load and impact-resistance requirements.
Zoning Confirmation — Confirm Parcel Eligibility
Before designing, confirm your parcel's zoning district, any overlay districts (historic, flood zone), HOA/deed restrictions, and ADU eligibility under ULDR Section 47-19.2. Contact Fort Lauderdale Development Services for pre-application guidance specific to your address.
Design Within 600 Sq Ft / 49% / 1-Bed Limits
Your ADU cannot exceed 600 sq ft OR 49% of the primary home's floor area (whichever is more restrictive), and is limited to 1 bedroom and 1 bathroom (or a studio/efficiency layout). Work with your architect to confirm the 49% calculation against your primary home's existing square footage.
Hire a Florida-Licensed Architect
Fort Lauderdale does not offer free pre-approved ADU plans. Engage a Florida-licensed architect familiar with ULDR Section 47-19.2, Broward County HVHZ construction requirements, and Fort Lauderdale's permitting process. Budget $3,000–$8,000+ for design fees.
Submit Permit Application via LauderBuild
Submit your building permit application through the LauderBuild portal. Required documents include: completed application, current property survey, site plan with setback dimensions, floor plans and elevations (all four sides), structural drawings, energy compliance calculations (RESCHECK), and contractor license and insurance.
Trade Permits — Electrical, Plumbing, Mechanical
Separate trade permits are required for electrical, plumbing, and mechanical work. These are typically pulled by licensed subcontractors. Confirm with LauderBuild whether trade permits are submitted with the main application or separately after the building permit is issued.
Construction and Inspections
Build per approved plans. Schedule all required inspections via LauderBuild: footings/foundation, framing, rough electrical/plumbing/mechanical, insulation, final. All construction must comply with Florida Building Code HVHZ requirements — impact-rated windows, doors, and roof systems are standard in Broward County.
Certificate of Occupancy + Annual Certificate of Use
After passing final inspection, obtain the Certificate of Occupancy (CO). If renting the ADU, you must also apply for an Annual Certificate of Use from Fort Lauderdale Development Services. This certificate must be renewed each year and is a legal requirement for ADU rental operations.
3. Required Documents Checklist
Standard documents for a Fort Lauderdale ADU permit via LauderBuild:
Post-construction: Annual Certificate of Use application required before renting the ADU.

Florida Private Provider Program
Florida homeowners may hire a state-approved Private Provider firm to conduct plan review and inspections independently of the city's queue. This can reduce review timelines by several weeks. Find registered Private Providers at floridabuilding.org.

30% federal tax credit (through 2032) for solar panels and battery storage installed on the ADU. Florida has 0% state sales tax on solar equipment and a property tax exemption for residential solar installations.
FPL Rebates
Florida Power & Light offers rebates for qualifying energy-efficient appliances, HVAC systems, and insulation — applicable when outfitting your ADU. See fpl.com/rebates for current programs.
Historic District Review (if applicable)
Properties in Fort Lauderdale historic districts may require additional review. Contact Development Services to determine if your parcel is within a historic overlay.
6. Renting Your ADU — Broward County Market
Fort Lauderdale's rental market is driven by its proximity to Miami, the marine and yachting industry, Fort Lauderdale-Hollywood International Airport, Port Everglades, financial services, and healthcare employment. Long-term ADU demand is strong and relatively stable.
Long-Term Rental Market
| Studio/Efficiency ADU Estimate | $1,300–$1,600/month (2025–2026 market data) |
| 1-Bedroom ADU Estimate | $1,500–$2,000/month |
| Key Demand Drivers | Fort Lauderdale-Hollywood International Airport, Port Everglades, Broward Health, Nova Southeastern University, financial services, yachting/marine industry, proximity to Miami |
| Vacancy Risk | Moderate to low — Broward County market is active year-round; lower vacancy than seasonal tourist markets |
| Seasonal Pattern | Less seasonal than Palm Beach or Treasure Coast markets; airport and healthcare employment provide year-round anchor demand |
| Premium Zones | Las Olas, Victoria Park, Rio Vista, downtown Fort Lauderdale, and waterfront corridors command higher rents |
Short-Term Rentals (Airbnb / VRBO)
STR PROHIBITED in Fort Lauderdale Residential Zones
Short-term rentals of less than 30 days are prohibited in Fort Lauderdale residential zones under the current ULDR. Do not plan to operate your ADU as an Airbnb or VRBO. Build your rental income model around long-term tenants (30+ day rentals) only. Violating this prohibition may result in code enforcement fines and could jeopardize your Certificate of Use.
Long-Term Rental Logistics
7. Common Pitfalls & How to Avoid Them
Exceeding the 49% floor area rule
The 600 sq ft cap only applies if 49% of your primary home's area is larger. If your primary home is 1,100 sq ft, 49% = 539 sq ft — your ADU is capped at 539 sq ft, not 600. Have your architect calculate this before finalizing plans.
Planning for Airbnb or short-term rental income
STRs under 30 days are prohibited in Fort Lauderdale residential zones. Do not design or purchase with STR income in mind — the business model won't be legally permitted.
Failing to obtain the Annual Certificate of Use
The Annual Certificate of Use is a legal requirement to rent your ADU in Fort Lauderdale. Renting without it risks code enforcement fines and invalidates your rental operation. Apply for it immediately after receiving your Certificate of Occupancy.
Owner-occupancy violation
Fort Lauderdale requires the owner to occupy either the main home or the ADU. If you plan to rent both units simultaneously, you are not eligible for an ADU permit under current rules. Verify occupancy requirements with Development Services.
Skipping HOA / deed restriction review
City permits do not override private covenants. Review your CC&Rs before hiring an architect — some HOAs in Fort Lauderdale neighborhoods prohibit detached accessory structures entirely.
Underestimating HVHZ construction costs
Broward County is in Florida's High Velocity Hurricane Zone. Impact-rated windows, doors, and roof systems are required — these add $10,000–$30,000+ compared to standard construction. Factor this in early.
Underestimating Broward County impact fees
Broward County assesses impact fees on new residential units. Budget $3,000–$8,000+ and get a written estimate from Broward County Development Services before finalizing your construction budget.

What is the Annual Certificate of Use for Fort Lauderdale ADU rentals?
Fort Lauderdale requires an Annual Certificate of Use for all ADU rental operations. This certificate must be renewed each year and confirms the property continues to meet code requirements.
