Summary
Livermore treats any property condition that breeds or harbors rodents and other vectors as a public nuisance per se. LMC § 8.14.030 singles out vegetation "likely to harbor rodents or vermin" and any activity that supports the "development, attraction, or harborage of vectors," and the mere presence of vectors in their developmental stages is prima facie evidence the property is a nuisance.
"Vector" means any animal capable of transmitting human disease or capable of producing human discomfort or injury, including but not limited to mosquitoes, flies, mites, ticks, other arthropods, rodents and other vertebrates. ...

Any activity, including the maintenance of a building, structure, property, or water, that supports the development, attraction, or harborage of vectors, or that facilitates the introduction or spread of vectors, or that is a breeding place for vectors.

Violations & Fines
Maintaining or allowing a rodent- or vector-harboring condition is unlawful under LMC § 8.14.050, and each day it continues counts as a separate offense. Because vector nuisances threaten public health, § 8.14.060(C) lets the City skip the standard notice-and-hearing sequence and use the emergency summary abatement procedure in § 8.15.040, which allows the City to abate the condition immediately using City resources and recover its costs from the responsible party under Government Code §§ 38773 and 38773.1.
