Backup generators in Murrieta must comply with MMC 9.02 noise limits during exercise cycles, with exemptions during actual power outages and declared emergencies.
Standby generators installed at Murrieta homes and businesses must comply with MMC 9.02 noise limits during testing and exercise operation, typically 55 dBA daytime and 45 dBA at night at the receiving property line. Weekly self-test cycles should be scheduled during daytime hours and not exceed 20 minutes in duration. Full load tests or extended exercises may exceed limits briefly but must be conducted during permitted hours with advance neighbor notice for commercial installations. Emergency operation during actual power outages, Public Safety Power Shutoffs (PSPS), or declared emergencies is exempt from noise limits. New permanent generator installations require building permits and must meet setback requirements (typically 5 feet from property lines and 3 feet from structures) plus manufacturer clearance specifications. Acoustic enclosures and sound walls are commonly required for larger units. Portable generators for construction, events, or temporary use are regulated under construction noise rules. Generators powered by propane or diesel must also meet fuel storage requirements under the California Fire Code.
