Rohnert Park FAQ
What hours can contractors work in unincorporated Sonoma County?
Permit Sonoma's standard condition is 7:00 a.m. to 7:00 p.m. Monday through Saturday, with no construction on Sundays or federal holidays. These hours come from the General Plan Noise Element rather than a single ordinance section, and Permit Sonoma enforces them through use-permit conditions, grading-permit conditions, and as the operative limit when responding to a noise complaint under Chapter 3, Article III of the County Code. Cities like Santa Rosa, Petaluma, and Sonoma set their own (often slightly different) construction hours.
Can I work on my own house on a Sunday in unincorporated Sonoma County?
Owner-occupied minor repairs that don't require a building permit - interior painting, light carpentry, indoor work that doesn't generate noise audible at the property line - generally fall outside the construction-hours restrictions. But any work that requires a permit (roofing, exterior framing, additions, grading) or that uses power equipment audible to neighbors should be confined to 7 a.m. to 7 p.m. Monday through Saturday. Power saws, jackhammers, generators, and similar equipment operating on Sunday in a residential neighborhood will draw a Sheriff response and possible citation under Sec. 3-41.
Are wildfire rebuilds exempt from construction hours?
No - rebuilds of homes destroyed in the 2017 Tubbs Fire, 2019 Kincade Fire, 2020 Glass Fire, and 2020 Walbridge Fire follow the same construction-hour rules. Permit Sonoma expedited rebuild permits and waived some fees but did not relax noise hours. The exception is genuine emergency or public-safety work - utility crews restoring power, water, or gas service, or work directed by CAL FIRE or the Sheriff's Office of Emergency Services - which can proceed outside normal hours.
