Yucaipa, CA Noise Ordinances: Construction Hours (2026)

Yucaipa Development Code § 87.0905 sets the noise rules for the City of Yucaipa in San Bernardino County, and the construction window sits inside its list of exempt noises. Subsection (e)(1)(C) exempts temporary construction, repair, or demolition activities between 7am and 7pm, except Sundays and Federal holidays. The vibration section, § 87.0910(c)(1)(B), uses the identical window for temporary construction, maintenance, or demolition.

The 7am to 7pm wording is an exemption, not a separate curfew, so work outside it is judged against the ordinary limits. For residential receiving property, the table in subsection (b)(1) lists 55 dBA for 7am to 10pm and 55 dBA for 10pm to 7am. Subsection (b)(2) bars any source of sound that causes a measured level on any other property, incorporated or unincorporated, above the noise standard for more than 30 minutes in any hour, above the standard plus 5 dBA for more than five minutes in any hour, above the standard plus 10 dBA for more than five minutes in any hour, above the standard plus 15 dBA for more than one minute in any hour, or above the standard plus 20 dBA for any period of time. Under subsection (d), impact noise or simple tone noise lowers each level by 5 dBA. Readings are taken with a sound level meter on the A-weighted scale, and the Director of the Community Development Department serves as the noise control officer.

Grading has its own clock. Yucaipa Municipal Code § 15.12.210 says grading and equipment operations within one-half mile of a structure for human occupancy shall not be conducted between the hours of eight p.m. and seven a.m. or on Sundays and federal holidays. The city official can permit specific hours outside that window after finding the operations are not detrimental to the health, safety, or welfare of the inhabitants of the structure, and permitted hours can be shortened if the city or the building official finds a previously unforeseen effect on the surrounding community. A separate rule in § 10.04.040(H)(2) bars mechanical work, and routine maintenance or repair work that causes an excessive amount of noise, before eight a.m. or after eight p.m. on a truck tractor parked in a residential driveway.
