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

§ 4-11-610(A) is the specific building-exterior standard: surfaces and roofs must be maintained and painted, free of significant cracks, missing materials, or warping caused by dry rot, pest infestation or fungus that either threaten the structure or leave it looking dilapidated, decaying, disfigured or partially ruined. The 'responsible party', any owner, lessee, tenant or agent who causes or permits the violation, including by failing to correct it after City notice, is liable under § 4-11-603's definitions. A violation is a misdemeanor under § 4-11-605, but before any citation the Chief Building Official must first make a reasonable effort to contact the responsible party and allow at least 14 days to correct the problem under § 4-11-630.

If that informal contact doesn't resolve it, the City posts a 'Notice to Abate Nuisance' in letters at least one inch tall, giving the owner 10 working days to fix the pest infestation or other listed defect under § 4-11-632, with a right to appeal to the Zoning Administrator and then the City Council under § 4-11-633. Materials lawfully stored inside an enclosed structure or behind a solid fence are exempt under § 4-11-606, as long as they aren't a health or safety hazard. Note this standard does not reach single-family homes, it applies only to nonresidential and multifamily apartment property.
