Monterey Park’s short‑term rental ordinance requires a permit to own, operate or advertise a rental of less than 30 days, and the permit number must appear in all advertisements. General standards limit overnight occupancy to two guests per bedroom plus two, require the primary occupant to be at least 18 and sign an acknowledgement, restrict parking to off‑street spaces and prohibit loud parties and other nuisances; owners must post Good Neighbor guidelines and respond to complaints promptly. A 13 % transient occupancy tax is due on rentals, and operators must collect and state the tax separately; they cannot advertise absorbing it. Source: https://ecode360.com/36004004
