Construction hours in Ontario, CA — sometimes called construction noise rules or contractor work-hour ordinances — set when contractors can run power tools, hammers, and heavy equipment.
Ontario Municipal Code section 5-29.09 limits noise-producing construction, remodeling, grading and demolition to 7:00 a.m. to 6:00 p.m. on weekdays and 9:00 a.m. to 6:00 p.m. on Saturday and Sunday, unless the activity complies with the dB limits in section 5-29.04 or 5-29.05.
OMC section 5-29.09(a) provides that no person engaged in construction, remodeling, digging, grading, demolition or related building activity shall operate any tool, equipment or machine in a manner that produces loud noise disturbing a person of normal sensitivity in the vicinity, or an officer, on any weekday except between 7:00 a.m. and 6:00 p.m., or on Saturday or Sunday between 9:00 a.m. and 6:00 p.m. Landowners, contractors and employers are equally barred from allowing crews to violate these hours (subsection (b)). Exceptions exist for emergency construction authorized by the City Manager, certain public-works projects, and any construction that complies with the noise limits in sections 5-29.04 or 5-29.05. Construction noise is expressly carved out of the general Chapter 29 standards by the exemption in section 5-29.06(d) and routed to this section.
Construction outside permitted hours is an infraction under section 5-29.17 punishable by a fine under OMC section 1-2.01, with each day a separate offense; administrative citations (OMC 1-5.04) and nuisance abatement are also available.
