Unincorporated Solano County enforces nighttime quiet hours through Solano County Code §21-10 (Disturbing the Peace). Any non-agricultural noise that exceeds 65 dBA at the property line between 10:00 p.m. and 6:00 a.m. is per se a disturbance of the peace. California Penal Code §415 provides backup authority statewide. Cities (Vallejo, Fairfield, Vacaville, Suisun City, Benicia, Dixon, Rio Vista) have their own ordinances.
Unincorporated Solano County has no dedicated construction-hours ordinance. Construction noise is governed indirectly by Solano County Code §21-10 (Disturbing the Peace), which makes any non-agricultural noise exceeding 65 dBA at the property line between 10:00 p.m. and 6:00 a.m. a per se disturbance. In practice construction work is therefore limited to roughly 6:00 a.m.–10:00 p.m. Cities set their own stricter limits.
Solano County Code §4-73 declares any dog, cat, fowl, or other animal that 'by habitual howling, yelping, barking or other noise disturbs or annoys persons in the neighborhood' to be a public nuisance.
