Florida Tiny Home & Container Home Zoning Laws
Florida regulates small homes primarily through the statewide Florida Building Code, while individual counties and cities control land use through their own zoning. There is no single statewide minimum square footage for permanent tiny homes, but the rules vary significantly once you get to the county level.1,5
- A foundation-built tiny home is a standard single-family dwelling under the Florida Building Code; a THOW is generally treated as an RV.
- Florida has adopted IRC Appendix Q, easing ceiling-height and loft requirements for homes under 400 sq ft.
- Coastal builds face added requirements: wind-borne debris impact windows and flood elevation design.
- A 2026 statewide ADU bill (SB 48) passed the Senate 38–0 but died in the House — no statewide ADU mandate exists yet.
- Pasco County permits ADUs but explicitly bars using an RV or mobile home as one.
The most important distinction in Florida: a tiny home on a permanent foundation is treated as a standard single-family dwelling under the Florida Building Code, subject to the same structural and safety requirements as any house. A tiny home on wheels (THOW) is generally treated as a recreational vehicle under Florida Statute §320.01, which restricts it to RV parks and generally prohibits using it as a primary residence in standard residential zones.2,5
1. Foundation-Built Homes: Florida Building Code Applies
Florida has adopted IRC Appendix Q, which provides relaxed ceiling-height and loft requirements specifically for dwellings under 400 square feet, making compliant small permanent homes more achievable.6 Beyond that, a foundation-built tiny home must meet the same structural, electrical, plumbing, and energy requirements as a full-size house, including Florida-specific requirements like wind-borne debris impact windows (governed by the Florida Building Code's wind-borne debris region provisions, published at floridabuilding.org) and flood elevation design in coastal areas.5
2. Homes on Wheels Face a Harder Path
If a THOW carries RVIA certification, Florida typically treats it as a recreational vehicle: legal to park in RV parks, but generally not usable as a primary residence in a standard residential zone.2 If instead it's built to the ANSI A119.5 park model standard and stays under 400 square feet, it falls under manufactured housing rules regulated by the Florida Department of Highway Safety and Motor Vehicles instead — a different, sometimes more workable, regulatory path.2
3. County-by-County: Real Examples
This is where Florida gets genuinely complicated, and generic statewide guidance stops being useful. A few real, current examples:
| County / City | Notable Rule |
|---|---|
| Brevard County | Allows dwellings as small as 200 sq ft on permanent foundations in certain agricultural and rural residential zones; setbacks start at 25 ft front, 7.5 ft side3 |
| Miami-Dade County | Authorizes tiny houses as ADUs ("efficiencies, studios, guesthouses") with a Certificate of Use; eligible lots must be at least 7,500 sq ft in AU, EU, RU, and certain GU zones4 |
| Sarasota County | Increasingly ADU-friendly, allowing units up to 750 sq ft in most single-family residential zones; owner must live in the main house or the ADU7 |
| Pasco County | Permits ADUs in single-family zones as of early 2025, but explicitly prohibits using an RV or mobile home as an ADU — it must be permanent, factory-built, or site-built7 |
| Lee County | Permits tiny homes on foundations in rural and agricultural zoning districts; minimum lot sizes start around 7,500 sq ft in some residential zones3 |
4. The 2026 ADU Bill: What Actually Happened
Senate Bill 48 would have required every Florida city and county to allow ADUs by right in single-family zones by December 1, 2026, and even included a provision directing state researchers to study the potential of tiny homes specifically.8 It cleared the Senate unanimously, 38–0, on February 4, 2026 — a real shift from 2025, when a similar bill never got a floor vote. But it died in House messages on the final day of the 2026 session, March 13, 2026, over an unresolved dispute with the House's short-term rental provisions.8,9 Florida still has no statewide ADU mandate as a result, and the patchwork of city and county rules described below remains the operative law. Advocates and legislators are expected to bring a similar bill back in the 2027 session, likely with the short-term rental language separated out to avoid the same dispute.9
5. Costs Specific to Florida
Professionally built tiny and container homes in Florida run roughly $42,000 to $175,000 and up, depending on size, materials, and hurricane-code compliance requirements specific to the state.3 Coastal and wind-zone construction requirements can add meaningfully to the cost compared to inland builds.
Research record: A previous version of this page described SB 48 as still pending. For this update, we checked the bill's actual final status directly on the Florida Senate's own bill-tracking page, which corrected that. We're not aware of a refiled 2027 version yet; we'll update this page once one exists rather than speculate on its terms in advance. Information last checked August 2026.
How to Verify Your Specific Situation
- Identify your property's exact zoning designation through county records, not just the city name.
- Search your county's code for both "tiny house" and "accessory dwelling unit" — different counties use different terminology.1
- Confirm whether your planned structure is a foundation build, a THOW, or a park model, since each follows a different regulatory path in Florida.
- Call the local planning department directly before purchasing land or a home with a specific placement plan in mind.
Before you buy land in Florida, run the full checklist.
