Tiny homes in St. Louis, Missouri — zoning rules, THOW parking, builder costs, and what you need to know before buying.
Last researched April 2026
St. Louis has a humid continental climate with hot humid summers, cool springs and autumns, and cold winters that typically bring 17-19 inches of snow per year. The city is defined by its Gateway Arch, Forest Park, the Mississippi and Missouri river confluence, and a lively food scene that spans toasted ravioli, barbecue, and craft beer. Housing remains notably affordable: median home prices hover around $250,000-$425,000 depending on neighborhood, and median rents run near $1,250-$1,412, giving tiny home dwellers a substantial cost advantage against the U.S. average. The 2025 BB60 ADU ordinance signals a welcoming shift for accessory dwellings, and organizations like Veterans Community Project and the city's 900 N. Jefferson tiny-house village demonstrate an expanding role for small, purpose-built homes in St. Louis's housing landscape.
The City of St. Louis passed Board Bill 60 in 2025, amending Title 26 of the Zoning Code to define, permit, and regulate Accessory Dwelling Units citywide with an effective date of September 29, 2025. Tiny homes on permanent foundations can qualify as ADUs provided they meet setback, lot-width (generally 50 feet minimum), and lot-area (5,000 sq ft minimum) standards and are designed to be compatible with the primary residence. THOWs are classified as recreational vehicles under Missouri state law and are not permitted as permanent residences in most residential St. Louis zones as of April 2026. The city is separate from St. Louis County, which maintains its own residential tiny-house checklist and ordinances; County rules apply to unincorporated areas and individual municipalities within the county may layer additional requirements. Permit fees, owner-occupancy specifics, and short-term-rental restrictions under BB60 are detailed in the Board Bill text — contact the St. Louis Planning and Urban Design Agency for the current application package. Verify current requirements with your local planning department before purchasing land or beginning construction.

St. Louis's new ADU framework under Board Bill 60 (effective September 29, 2025) allows Accessory Dwelling Units on qualifying single-family-zoned parcels citywide. ADUs must generally be on lots at least 50 feet wide and 5,000 square feet in area, meet setback and height limits, and be architecturally compatible with the primary residence. Owner occupancy of either the primary dwelling or the ADU is typically required, and short-term rental of the ADU is limited. Tiny homes on permanent foundations that meet the IRC (including Appendix Q for dwellings 400 sq ft or smaller) can qualify as ADUs when designed to BB60 standards; THOWs do not qualify. Permit applications go through the St. Louis Planning and Urban Design Agency and the Building Division. Fee schedules, exact size caps, and off-street parking requirements are set in the Board Bill text and implementing zoning regulations — consult the current Title 26 and BB60 for specifics before proceeding.
Communities, RV parks, and parking options in and near St. Louis.
THOW parking in the City of St. Louis is restricted to licensed RV parks, campgrounds, and manufactured-home parks; long-term THOW habitation on most private residential lots is not permitted as of April 2026 because Missouri classifies THOWs as recreational vehicles. In unincorporated St. Louis County, THOWs are also not permitted as permanent residences in residential neighborhoods but are allowed in designated mobile home parks. Pin Oak RV Resort in Villa Ridge (along I-44, about 40 miles west of downtown) is a well-known full-hookup option for extended stays near St. Louis. Several metro parks — including Bab's RV Park less than 20 miles west of downtown and Mulberry RV Gardens in the broader metro — cater to long-term RV residents, though site availability varies. For long-term THOW living within city limits, the most reliable legal path is typically a designated mobile home park or rural land in Jefferson, Franklin, or St. Charles County where zoning may be more permissive. The St. Louis metro has also seen growth in non-profit tiny-home villages: Veterans Community Project's four-acre campus in the Jeff-Vander-Lou neighborhood houses formerly homeless veterans and is not available for general THOW parking, and the 900 N. Jefferson Ave. city-supported tiny-house village (funded in part with federal CARES Act dollars) targets unhoused individuals rather than private THOW owners.
