San Jacinto, CA Public Health Rules: Rodent Control (2026)

San Jacinto handles rodent and vector conditions through the property nuisance list rather than a standalone rat ordinance. Item C.7 of § 8.44.050 declares overgrown vegetation likely to harbor rats, vermin and other nuisances a public nuisance when it harms neighboring properties or property values or blocks the view of drivers on public streets or private driveways and is visible from a public street. Item C.12 covers breeding places for flies, including any barn, stable, chicken house or yard, manure or fertilizer pile that is a breeding place for flies or liable to become one. Item C.13 covers any accumulation of garbage or filth. Item C.16 covers any pool of water accumulated in a way that is, or may become, a breeding place for mosquitoes.

Two other chapters add detail. Section 8.20.010 adopts Riverside County Ordinances 523 and 527, which control and abate flies, and the council filed them as exhibits in the city clerk's office. For abandoned or distressed residential property, § 8.60.050(A) requires the property to be kept free of weeds, dry brush, dead vegetation, trash, junk and debris, and § 8.60.050(D) requires pools and spas to be kept in working order so the water remains clear and free of pollutants and debris that could be a breeding ground for mosquitoes and other vectors, or drained and kept dry.

Abatement follows chapter 8.44. The code enforcement officer, who under § 8.44.020 is the city manager and authorized representatives, notifies the owner, lessee or occupant and sets an abatement period of not less than ten days under § 8.44.070. The city can enter the property under § 8.44.090 to post or serve notice and to inspect. If the owner does not clean up, § 8.44.180 lets the city abate through city forces or private contract, and the cost is recovered under § 8.44.190 and § 8.44.220.
