Summary

In unincorporated Story County, any building or place that breeds, harbors, feeds or shelters vermin or pests, including mice, rats, flies or cockroaches, is a declared public health nuisance under County Code Section 55.07. The Story County Environmental Health Department enforces the rule and can order occupants to vacate an infested property until it is cleaned up.

Violations & Fines

Enforcement of Chapter 55 nuisance violations runs through Chapter 72. EH first seeks voluntary compliance (Section 72.04); if that fails, a Notice of Violation gives the violator 30 days to abate or submit a compliance schedule (Section 72.05). Continued noncompliance triggers a County infraction citation with a civil penalty under Iowa Code Chapter 331 (Section 72.06), and each day the violation continues can count as a separate offense.
