Amplified sound outdoors, hot tub and pool use after the quiet hour, and outdoor gatherings exceeding the STR's stated occupancy are typically prohibited by permit condition. Each rental must post the 24-hour local contact, occupancy limits, and quiet-hours policy inside the unit, and the owner or designated agent must respond to noise complaints within 45 minutes. In Lake Arrowhead, Big Bear, Wrightwood, Joshua Tree, Pioneertown, and Yucca Valley unincorporated neighborhoods, which contain thousands of STRs, Code Enforcement and the Sheriff route complaints to a contracted STR hotline. Three verified noise or nuisance violations within a 12-month period typically trigger permit suspension.
