Tustin, CA Noise Ordinances: Construction Hours (2026)

Section 4616(2) covers the erection, demolition, alteration, repair, excavation, grading, paving or construction of any building or site, and it also reaches the trucks and equipment making material deliveries or servicing the job that operate on or near the site. The same clock applies to pile drivers, power shovels, pneumatic hammers, grading and excavating machinery and paving equipment under Section 4616(3). A companion exemption in Section 4617(e) confirms the normal working window, construction noise between 7:00 a.m. and 6:00 p.m. weekdays and 9:00 a.m. and 5:00 p.m.

Saturdays, excluding city-observed federal holidays, is not a chapter violation at all. Work outside the restricted hours is not automatically forbidden forever: the Building Official can grant a written temporary exception for private property, and the Director of Public Works can do the same for public property, in cases of urgent necessity or where the work will not adversely affect neighboring properties or the community's health, safety and welfare. A waiver request has to be in writing with the specific times, dates, locations and activity described, and any approval can be summarily revoked by the official who granted it, with notice going to the requestor, the Police Department and the project file. Community Development and the Tustin Police Department field complaints and confirm whether a project is working under an active waiver.
