Full Breakdown
060 declares it a public nuisance for any property owner, lessee, occupant or person in charge of property, or anyone conducting a business or activity in the city, to cause, permit or allow specified health and safety conditions. Subsection (A) covers breeding or harborage places for invertebrate and vertebrate vectors under conditions of known public health significance, expressly naming mosquitoes, flies and rodents. The same section reaches related conditions that typically accompany a rodent problem: subsection (D) covers infectious and related wastes and their odors, including pet droppings, excrement, manure accumulations and putrid matter under circumstances endangering public health, and subsection (H) covers standing water in a pool, spa, pond or similar feature that is unhealthy or likely to attract harmful insects or bacteria.
23: the code enforcement officer can declare the condition a nuisance after a hearing, issue a written notice to abate that specifies the conditions and the number of days to fix them, and, if the owner does not comply, have the city perform the abatement and bill the cost back to the property as a lien. 090 also lets the code enforcement officer skip the standard notice period and take emergency abatement action when the condition is an immediate hazard or threat of harm.
Violations & Fines
Section 8.23.220 makes a Chapter 8.23 violation a misdemeanor, punishable by a fine of up to $1,000.00, imprisonment of up to six months, or both, with each day the rodent-breeding condition continues counted as a separate offense. The city can also recover its abatement costs as a lien against the property under Section 8.23.200.
