Florida’s sunshine, mild winters, and affordable land make it a dream location for tiny home living. But if you want to build, buy, or move a tiny home in the Sunshine State, you need to understand the patchwork of laws and local rules that govern where and how tiny houses can be placed. Here’s a comprehensive look at Florida tiny home laws, including where tiny homes are most welcome, what’s required, and key things to consider before making your move in 2025.
Are Tiny Homes Legal in Florida?
Florida has no single statewide law for tiny homes. Instead, rules are set by individual counties, cities, and even homeowner associations. Local governments control zoning, building codes, minimum house sizes, and where you can place a tiny home—so what’s allowed in one area may be illegal just a few miles away.
Quick Picks: Best Florida Cities and Counties for Tiny Homes
- Sarasota County: One of the first Florida counties to embrace tiny homes, including “tiny house villages” and flexible ADU rules. (Check local code)
- Orlando & Orange County: Allows ADUs (accessory dwelling units) and is open to innovative housing, but most tiny homes must be on a foundation and meet residential codes. (Contact planning office)
- St. Petersburg & Pinellas County: Welcomes ADUs and has developed a few tiny home-friendly neighborhoods. (More info)
- Brevard County: Some unincorporated areas allow tiny homes on foundations and have fewer minimum size requirements for rural land.
- Walton, Levy, and rural counties: Often allow small homes, cabins, and THOWs (tiny houses on wheels) in rural or agricultural zones, with fewer restrictions than city areas.
- Tampa, Miami, and Jacksonville: Major cities permit ADUs and backyard cottages with varying restrictions, but zoning and minimum size requirements can be strict.
Always contact your county or city zoning department before buying land or building a tiny home—Florida laws can change quickly, and rules differ even within the same county.
Buyer’s Guide: Key Things to Consider for Tiny Homes in Florida
- Type of Tiny Home: Is your tiny home on a permanent foundation, or is it a tiny home on wheels (THOW)? Florida law treats these differently.
- Building Codes: Most areas use the Florida Building Code, based on the International Residential Code (IRC). Some towns have adopted “Appendix Q” for tiny homes under 400 sq. ft.
- Zoning Laws: Tiny homes must be built or parked in residential, mixed-use, or agricultural zones that allow small dwellings or ADUs. Rural land is usually more flexible.
- Minimum Square Footage: There’s no statewide minimum, but most cities set a minimum between 375–700 sq. ft. for a permanent residence. Some allow smaller ADUs or backyard cottages.
- Utilities: All permanent tiny homes must have approved water, sewer/septic, and electricity. Off-grid living is possible in rural counties but is not common in cities.
- Permits & Inspections: A building permit and inspections are required for any legal permanent home.
- HOA & Neighborhood Rules: Homeowner associations can ban tiny homes, RVs, or nontraditional dwellings, even if local zoning allows them.
Detailed Reviews: Florida Tiny Home Laws by Category
Tiny Homes on Foundations
These are the simplest to legalize—especially if built to code on your own land. Sarasota County, Orlando, and some rural counties allow tiny homes on permanent foundations as primary or accessory dwellings.
- Most cities require 375–700 sq. ft. minimum (but some areas allow as small as 170 sq. ft. for ADUs)
- Must meet Florida Building Code, pass inspections, and be placed on a legal lot
- Allowed in residential, mixed-use, and some agricultural zones
Final Verdict: The best route for legal, year-round tiny home living in Florida—especially as a primary residence or ADU.
Tiny Homes on Wheels (THOWs)
Treated as RVs in most of Florida. You can only live in a THOW full-time in RV parks, campgrounds, or on rural/agricultural parcels where the county allows it. Most cities prohibit permanent backyard use of THOWs.
- Must be registered as a vehicle and meet Florida RV standards
- Allowed full-time only in RV parks, or in some rural counties if approved by zoning
- Often restricted to seasonal or temporary use on private lots
Final Verdict: THOWs are great for mobility and vacation living, but harder to use for legal full-time housing in most of Florida.
Accessory Dwelling Units (ADUs)
ADUs—backyard cottages or “granny flats”—are now legal in many Florida cities and counties, thanks to recent state and local reforms aimed at affordable housing.
- Must be on a property with a main home
- Size limits: typically 170–800 sq. ft.
- Must be permitted, inspected, and have utilities
Final Verdict: ADUs are the easiest and most popular way to add a legal tiny home in Florida.
