Construction hours in Hawthorne, CA — sometimes called construction noise rules or contractor work-hour ordinances — set when contractors can run power tools, hammers, and heavy equipment.
Hawthorne's Noise Regulations (Ordinance No. 2138) bar construction noise heard beyond the property line outside set hours: 7 a.m.-7 p.m. Monday-Friday, 9 a.m.-7 p.m. Saturday, and none on Sundays or City holidays. Construction may not exceed a 75 dBA hourly average at residential property. A DIY exception allows non-commercial work on your own property 10 a.m.-5 p.m. on Sundays/holidays.
The Construction Noise section of Hawthorne's re-enacted Noise Regulations chapter (Ordinance No. 2138) applies to anyone operating powered construction or landscape equipment, or erecting, demolishing, excavating, altering, or repairing a building, where the noise is received beyond the property boundary. The permitted hours are: Monday through Friday, 7:00 a.m. to 7:00 p.m.; Saturday, 9:00 a.m. to 7:00 p.m.; and no construction work on Sundays or City holidays. Even within permitted hours, construction activity may not cause an hourly average sound level greater than 75 decibels on property zoned or used for residential purposes. The ordinance carves out one narrow exception: a person may perform construction work on their own property, provided it is not carried on for profit or livelihood, between 10:00 a.m. and 5:00 p.m. on Sundays and City holidays. Because Hawthorne is incorporated, these city hours govern within city limits rather than any Los Angeles County construction-hours rule. Emergency work (to restore property to a safe condition or protect persons/property) is exempt if the city's Director of Planning and Community Development is notified.
Construction-noise violations are enforced under the penalties in the Hawthorne Municipal Code through Code Enforcement and the Police Department. The cost-recovery provision lets the city bill for repeat police responses to noise disturbances, up to $1,500 per subsequent response.
