Summary
Riverside property owners must exterminate rodent infestations the moment they discover them under RMC Chapter 6.22. The City inspects suspect properties, can issue a ten-day notice to abate through the Code Enforcement Division, and if the owner ignores it, the City does the extermination itself and bills the cost as a lien.
Every person possessing any place that is infested with rodents, as soon as their presence comes to his knowledge, shall at once proceed and continue in good faith to endeavor to exterminate and destroy the rodents, by poisoning, trapping, and in other appropriate means. ... The notice shall direct that the owner shall, within a period of ten days, commence to proceed and to continue to endeavor to exterminate and destroy the rodents, as required in this chapter. ... In the event the owner or person in charge or possession of the property affected by such notice, fails, neglects or refuses to proceed and to continue to endeavor to exterminate and destroy the rodents, within the time specified in Section 6.22.060, the City shall at once cause the rodents to be exterminated and destroyed.

Full Breakdown
RMC Section 6.22.010 requires every person possessing a rodent-infested place to "at once proceed and continue in good faith to endeavor to exterminate and destroy the rodents, by poisoning, trapping, and in other appropriate means." The City may inspect any property to check compliance, but Section 6.22.020 limits inspection of an occupied dwelling, hotel, or rooming house to between 9:00 a.m. and 5:00 p.m. When infestation is found, the Code Enforcement Division issues a written notice to abate under Section 6.22.030, giving the owner ten days to begin extermination; the notice is served personally or by registered mail plus a ten-day posting on the property (Section 6.22.040).
An owner who disputes the finding has ten days from service to file a written appeal with the City Clerk for a City Council hearing (Section 6.22.050); if no appeal is filed, the infestation is conclusively established. Once the compliance deadline in Section 6.22.060 passes without action, Section 6.22.070 lets the City "at once cause the rodents to be exterminated and destroyed." The City then bills the owner for costs exceeding $15.00; unpaid bills 45 days after billing become delinquent and, per Section 6.22.080, form a lien on the property, confirmed through a City Clerk report, a City Council hearing under Section 6.22.100, and filing with the County Auditor for collection on the property tax roll (Sections 6.22.090, 6.22.110, 6.22.130). Section 6.22.160 also lets the City order a building rodent-proofed, in whole or in part, when it constitutes a harborage.
Violations & Fines
Chapter 6.22 carries no dedicated fine for failing to exterminate; the City's remedy is to abate the infestation itself and recover costs as a property lien under Section 6.22.080. Separately, obstructing, hindering, or interfering with a City officer entering a property or performing abatement work under this chapter is a misdemeanor under Section 6.22.150, and unpaid lien assessments are collected the same way as delinquent municipal taxes, subject to the same foreclosure and sale procedures.
