Solano County has used a stop-gap overnight noise rule that prohibits non-agricultural noise exceeding 65 decibels at the property line between 10 p.m. and 6 a.m. Chapter 2.2 of the County Code (Section 2.2-70) regulates noise-making devices for crop protection in unincorporated areas. California Penal Code Section 415 (disturbing the peace) provides backstop authority for loud disturbances.
Solano County's primary nighttime noise rule was introduced as an interim 'stop-gap' overnight standard prohibiting any non-agricultural noise that exceeds 65 decibels at the property line between 10 p.m. and 6 a.m., pending a more comprehensive ordinance. Chapter 2.2 of the Solano County Code (Section 2.2-70) governs noise-making devices used for crop protection in unincorporated areas, including gas cannons and automatic exploders used to scare birds and wildlife from agricultural crops. California Penal Code Section 415 prohibits maliciously and willfully disturbing another by loud and unreasonable noise. California Civil Code Section 3479 defines a public nuisance. Active disturbances in unincorporated areas are handled by the Solano County Sheriff; ongoing nuisances are handled by Resource Management Code Compliance.
Violations of the overnight noise rule may be cited by the Solano County Sheriff under the County Code or, for active disturbances, under California Penal Code Section 415. Repeat or ongoing nuisances can be abated through Resource Management Code Compliance. Agricultural noise device misuse under Section 2.2-70 is enforced by the County Agriculture Department.
