LAMC §112.05 limits powered construction equipment operating within 500 feet of any residence to 75 dBA measured at 50 feet, and LAMC §41.40 confines noisy work to weekday daytime hours, Saturday mornings, with Sunday and holiday silence.
Under LAMC §112.05, construction equipment used within 500 feet of a residential zone may not exceed 75 dBA when measured at 50 feet from the source unless a specific variance is issued by the Board of Public Works. LAMC §41.40 layers on time restrictions: powered equipment may run 7:00 a.m. to 9:00 p.m. Monday through Friday and 8:00 a.m. to 6:00 p.m. Saturday. Sunday operation, federal holidays, and overtime windows are prohibited absent a noise variance. Pile drivers, jackhammers, and concrete saws often need quieter mufflers or sound blankets to comply. LADBS inspectors and LAPD officers may issue stop-work or citation notices.
Operating loud equipment outside permitted hours, exceeding the 75 dBA limit, or working Sunday or holidays draws LAMC §41.40 citations starting at $250 per violation, stop-work orders, and possible misdemeanor charges for repeat offenders.
