Broward County, FL Accessory Structures: Tiny Homes (2026)

Q: Can I build a tiny house on a lot in unincorporated Broward County?

Possibly. The Florida Building Code, Residential, 8th Ed. (2023) Appendix Q allows site-built tiny houses up to 400 sq ft and relaxes loft and stair rules. Whether you can place one as the principal dwelling on a BMSD lot depends on the lot's zoning district under Chapter 39, Article XVI, including lot-area, setback, and minimum dwelling-size rules. Contact Zoning@Broward.org to confirm the specific district's rules for your parcel.

Q: Are movable tiny homes on a chassis treated as houses?

No. Movable tiny homes on a chassis are governed by separate state law (Florida's movable tiny home statute) and are not the same as a site-built dwelling under the Florida Building Code. They cannot be permitted as a permanent FBC dwelling without converting to a fixed foundation that meets HVHZ wind-load and FBC requirements.

Q: Are the rules different inside the cities?

Yes. Chapter 39 only applies in the Broward Municipal Services District. Each of the 31 Broward cities (Fort Lauderdale, Hollywood, Pompano Beach, Davie, Plantation, Sunrise, Coral Springs, Pembroke Pines, Miramar, etc.) sets its own minimum dwelling size, ADU permitting, and accessory dwelling rules. The statewide FBC and HVHZ rules still apply, but local zoning controls placement.

Summary

Florida adopted IRC Appendix Q in the Florida Building Code, Residential, 8th Ed. (2023): a tiny house is 400 sq ft or less. In the BMSD, a tiny house must still satisfy Chapter 39 zoning, sit on a permitted foundation, and meet HVHZ wind loads.

Full Breakdown

Tiny houses in the BMSD face two layers of regulation. Construction: Florida adopted IRC Appendix Q in the FBC Residential, 8th Edition (2023), defining a tiny house as 400 sq ft or less excluding lofts and relaxing loft, ladder, and stair rules. A site-built tiny house in the BMSD must be permitted by Broward Building Code Services and meet HVHZ wind-load and Product Approval rules. Zoning: Chapter 39, Article XVI controls whether a tiny house is allowed as the principal dwelling, lot-area minimums, and setbacks. Broward has no tiny-house overlay. Movable tiny homes on chassis are governed separately under state law. The 31 Broward cities set their own ADU rules. Confirm with Zoning@Broward.org.

Violations & Fines

A tiny house in the BMSD without a Broward County permit is unpermitted construction and can trigger stop-work orders, after-the-fact fees, and code-enforcement penalties. Placing one in a district that disallows it is a Chapter 39 violation.
