Florida Zoning for Residential Development: A Cheat Sheet

If you're developing in Florida today, the rules are different than they were a few years ago. The Live Local Act (SB 102, 2023) and its amendments in 2024 (SB 328), 2025 (SB 1730) and 2026 (HB 1389, ch. 2026-179) let qualifying affordable multifamily and mixed-use projects bypass rezoning on commercial, industrial and mixed-use land, and limit how far local governments can restrict their density and height. Most homeowners and even some developers are still working from outdated assumptions.

Here's what actually applies now.

How Florida zoning is structured

• State law (Florida Statutes) sets the floor — including the Live Local Act's preemptions.
• County comprehensive plans and land development codes apply outside cities.
• Inside city limits the city's code applies; county rules generally govern unincorporated areas (some county-wide rules, such as charter-county provisions, still apply).
• Overlay districts and HOAs add another layer that can be stricter than base zoning.

The Live Local Act: what changed

Florida's Live Local Act preempts local zoning in specific cases to encourage workforce housing. Key provisions to know:

• Multifamily and mixed-use projects on commercial, industrial, or mixed-use land can be approved administratively — no rezone required — if at least 40% of units are rental units affordable (generally up to 120% of AMI under s. 420.0004) for at least 30 years. Mixed-use projects must be at least 65% residential. The 2025–26 amendments extended this to PUDs and flexibly zoned land, government-owned land, and qualifying religious-institution land over 3 acres.
• Density: a city or county may not restrict density below the highest currently allowed (or allowed on July 1, 2023) density on land in the jurisdiction where residential development is allowed. It's a floor on restrictions, not a bonus.
• Height: a city or county may not restrict height below the highest currently allowed (or allowed on July 1, 2023) height for a commercial or residential building within 1 mile, or three stories, whichever is higher. Next to qualifying single-family neighborhoods the cap can be 150% of the tallest adjacent building, up to 10 stories, and historic parcels use a ¾-mile radius. Since 2026, height can't be cut through setbacks or stepbacks.
• Property tax exemptions (s. 196.1978) for qualifying affordable units in larger multifamily projects. Terms and local opt-outs vary, so confirm eligibility with counsel.

ADU rules in Florida

ADU (accessory dwelling unit) rules are set locally. State law (s. 163.31771) lets, but does not require, cities and counties allow ADUs, and a 2026 bill to require them statewide (SB 48) did not pass. Many, but not all, Florida cities and counties allow ADUs: Tampa, for example, allows them only in designated neighborhoods, while Orlando allows them in all residential districts subject to lot size. The general framework:

• Maximum size: caps commonly range from about 500 to 1,000 sqft (for example, 400–800 sqft in unincorporated Miami-Dade RU-1, 950 sqft in Tampa, and 500 or 1,000 sqft in Orlando depending on lot size).
• Setbacks: vary by city; check your code.
• Height: varies by city; check your code.
• Owner occupancy: rules vary. Some cities, like Tampa, still require it (since October 2024 the owner may live in either unit); unincorporated Miami-Dade does not.
• Parking: some Florida cities waive or reduce replacement parking for ADUs under their own codes; check locally.

Setbacks, FAR, and lot coverage

Setbacks

The minimum distance between your building and the property line. For example, a Florida single-family lot might have a 25 ft front, 7.5 ft side, and 20 ft rear setback. Corner lots and waterfront lots add complications.

FAR (Floor Area Ratio)

Total building square footage divided by lot square footage. A 0.5 FAR on a 10,000 sqft lot means you can build up to 5,000 sqft of total floor area.

Lot coverage

The percentage of your lot that buildings can occupy at ground level — often 30–50% in residential zones. Driveways and pools usually don't count, but porches and decks often do.

Other regulations that quietly kill deals

1. Flood zone designations (AE, VE, X) — affect insurance, finished floor elevation, and what's even buildable.
2. Tree preservation ordinances — can require permits to remove specimens over a certain diameter.
3. Wetland and conservation buffers — can take a large share of your buildable area.
4. Historic district overlays — design review, materials restrictions, longer permitting.
5. Impact fees — water, sewer, school, transportation. Commonly $15K–$35K per single-family unit in Miami, Tampa and Orlando-area jurisdictions (2026).
6. HOA covenants — can be stricter than zoning. Always check.

How to actually verify what you can build

1. Pull the parcel in your county's GIS portal.
2. Confirm zoning, FLU (Future Land Use), flood zone, and overlays.
3. Read the city's land development code for that zone (don't rely on summaries).
4. Check for HOA covenants if applicable.
5. Run a feasibility study before making any offer or signing any contract.
