San Bernardino, CA Short-Term Rentals: Noise Rules (2026)

STR properties in San Bernardino fall under the same exterior noise standards as any residence. SBMC Chapter 8.54 caps residential exterior noise at roughly 55 dBA during the day and 50 dBA during nighttime hours, with Development Code Section 19.20.030 reinforcing the 65 dBA absolute ceiling for residential zones. Quiet hours run from 10 PM to 7 AM on weekdays and 10 PM to 9 AM on weekends and federal holidays. Hosts must post the quiet hours and the local contact phone number inside the STR and in the listing description. The local contact must answer within one hour and arrive on-site within a reasonable window to quiet a disturbance. Repeated police or code enforcement responses for the same address become part of the permit record, and three verified complaints within any 12-month window can lead to permit suspension for up to 180 days or full revocation after a hearing before the Planning Commission. Amplified outdoor music, hot tub parties after 10 PM, and large gatherings with more than the permitted occupancy are the most common grounds for complaint. California Civil Code 1940.2 tenant harassment protections do not apply to transient guests, so hosts retain authority to shorten or terminate a stay for noise violations without a full eviction process.
