Short-term rentals (STRs) in St. Louis, known locally as "non-occupied short-term rentals," are legal but subject to stringent regulations enforced by the City of St. Louis. Operators must obtain a permit, limited to four units per individual, and adhere to a minimum stay requirement of two nights. The thriving properties are predominantly urban apartments and homes, appealing both to tourists visiting attractions like the Gateway Arch and business travelers due to the city's corporate presence. The market experiences heightened activity during major events and conventions, making it a favorable environment for STR operators. The Department of Public Safety and its Building Division oversee the regulation of these rentals, ensuring compliance with safety and operational standards.
