Fairfield, CA Public Health Rules: Rodent Control (2026)

401 of Fairfield's Community Preservation ordinance lists the conditions that make property a public nuisance, and subsection (i) specifically targets vegetation that draws pests: dead, decayed, diseased or hazardous trees, weeds or overgrown vegetation likely to harbor rats, vermin or other pests, or which protrudes over or across a city street or sidewalk so as to substantially obstruct the clear passage of vehicles or pedestrians. The rule applies to any owner, lessee, occupant, or person with charge of premises in the city, commercial, industrial, or residential.

501 once a nuisance is confirmed and the responsible party has had a reasonable opportunity to correct it. 502 must identify the property, cite the specific nuisance subsection, describe the hazardous vegetation, and set a reasonable abatement deadline. 205 makes a first violation an infraction with a fine up to $100, a second violation within a year a misdemeanor with a fine up to $1,000 or up to six months in jail, and allows a court to order treble abatement costs against an owner with a second or subsequent nuisance judgment within two years.

401(q) separately reaches stagnant water that breeds mosquitoes or other insects, though it exempts reasonable yard-waste composting, giving the city two overlapping tools against vector-attracting conditions on the same property.
