Accessory Structures in Fort Lauderdale, FL: What Residents Actually Need to Know

If you live in Fort Lauderdale or are thinking about moving there, accessory structures are one of those things you probably won't think about until they affect you directly. Fort Lauderdale has 2 specific rules on the books covering different aspects of accessory structures, and some of them might surprise you.

ADU Rules

Fort Lauderdale permits an accessory dwelling (granny flat) only as an accessory to a single-family home in specified residential districts (RS-8, RD-15, RM-15 and others), capped at one bedroom/one bath or an efficiency and no larger than 600 square feet or 49% of the principal home, whichever is less.

Key details: City Code Section: ULDR 47-19.2 (Accessory dwellings). State Statute: Fla. Stat. 163.31771 (Accessory dwelling units). Max size: 600 sq ft or 49% of principal, whichever is less. Bedrooms: 1 bedroom/1 bath, or efficiency. Units per lot: 1 accessory dwelling per single-family lot.

Building or occupying an accessory dwelling without zoning approval and a building permit can result in code-enforcement action, daily fines, and an order to remove the unit or restore the structure to a permitted use. Units exceeding the one-bedroom and 600-square-foot caps, or located outside the permitted districts, are not approvable and may be cited as illegal second dwelling units.

Garage Conversions

Converting a garage to living space in Fort Lauderdale is reviewed under the ULDR accessory-dwelling standards and the parking rules of Section 47-20; lost required off-street parking generally must be replaced elsewhere on the lot, and corner-lot garages must keep an 18-foot setback for driveway stacking.

Key details: City Code Section: ULDR 47-19.2; parking per 47-20. Treated as: Accessory dwelling (47-19.2 standards apply). Parking: Replacement of lost required off-street spaces on lot. Corner-lot garage setback: 18 ft from street-adjacent property line. Corner-lot side-street setback: 15 ft minimum.

Converting a garage without zoning approval and a building permit can result in code-enforcement citations, daily fines, and an order to restore the garage or remove the unpermitted living space. Eliminating required off-street parking without providing replacement parking is a separate ULDR violation that can block permit approval.

The Bottom Line

Fort Lauderdale's accessory structures rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Fort Lauderdale is broadly strict or permissive.

These rules come from Fort Lauderdale's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
