Verified from official government sources
Missouri has no statewide STR preemption. Boone County has not adopted a dedicated short-term rental (Airbnb/VRBO) ordinance for unincorporated areas. On Feb. 8, 2024, the County Commission adopted Rental Housing Standards under the authority of Mo. Rev. Stat. §64.207 (HB 271, 2021), but those standards apply to longer-term rented residences, not vacation lodging. STR operators must still comply with the underlying zoning district, the Boone County Building Code, and Missouri sales/lodging tax rules. The City of Columbia (most STRs in the county are inside Columbia) enforces its own STR ordinance effective June 1, 2024.
Unincorporated Boone County does not levy a county lodging tax or STR registration fee. STR operators owe Missouri 4.225% state sales tax plus the Boone County 1.75% sales tax (6.225% combined minimum). Inside Columbia, the City adds a 5% lodging tax and STR business license/CUP fees.
Unincorporated Boone County has no STR-specific off-street parking ratio. The Boone County Zoning Ordinance sets baseline residential parking standards by district. On-road parking falls under the Boone County Roadway Regulations (no parking blocking traffic, on bridges, or impeding lawful traffic). Subdivision covenants often impose additional limits.
Unincorporated Boone County sets no STR-specific occupancy cap. Practical limits derive from the Boone County Zoning Ordinance's family/household definition, on-site septic system sizing under MO 19 CSR 20-3.060, and bedroom egress under the adopted IRC. Columbia's 2024 STR ordinance imposes city-specific tiered caps.
