STR occupancy in unincorporated St. Louis County is effectively governed by the family definition in SLCRO §1003.020: an individual or related persons, or up to 3 unrelated persons living as a single non-profit housekeeping unit using no more than 2 kitchens.
Without a dedicated STR ordinance, the §1003.020 family definition controls. The 3-unrelated-person cap means a single STR booking with 4 unrelated adults can technically be in violation. Enforcement is rare unless triggered by neighbor complaint. Many cities layer their own occupancy rules — Clayton requires conditional use review for any rental with >4 unrelated occupants.
Notice of Violation; up to $1,000/day; cease-occupancy order on continuing violations.
