The City of San Mateo's short-term rental ordinance (Chapter 5.66, Section 5.66.040) establishes strict occupancy limits. Occupancy is limited to two people per bedroom or ten people per property, whichever is less. This applies to overnight guests. Events including weddings, parties, corporate events, commercial functions, and any similar gatherings that could create neighborhood impacts are prohibited at STR properties. When the host is not present on-site, the property may be rented as an STR for no more than 120 days per year. Hosted stays (owner on premises) have no annual day limit. The local contact person must be available 24/7 and respond within 60 minutes to complaints.
Exceeding occupancy limits or hosting prohibited events may result in STR registration revocation. Violations of operating standards carry fines. Repeat violations may result in permanent loss of STR registration.
