New Port Richey, FL Accessory Structures: Tiny Homes (2026)

Pasco County permits tiny homes on permanent foundations as single-family dwellings subject to the Florida Building Code and underlying zoning district minimums. Florida adopted IRC Appendix Q, which provides relaxed ceiling-height and loft requirements for dwellings 400 sq ft or less, allowing compliant construction of small permanent homes. Minimum dwelling size requirements in certain Pasco zoning districts may effectively set a higher floor (often 750-1,000 sq ft in single-family residential zones), so a tiny home may only fit in AR (agricultural-residential) districts or as an ADU where permitted. ADU rules in the Pasco LDC allow accessory dwelling units under specific conditions including owner occupancy and size limits. Tiny homes on wheels (THOW) are classified as recreational vehicles or park model RVs under FL §320.01 and FL §513 and cannot be used as permanent dwellings in residential zoning districts; they must be located in licensed RV parks or mobile home parks. Utility connections (water, sewer/septic, electric) with permits are required for permanent occupancy. Septic systems under FL DOH rules may require sizing review.
