Summary
Troy requires every structure and exterior property to stay free of rodent harborage and infestation, with prompt extermination by approved, health-safe methods when rodents appear. Squirrels or chipmunks outside a structure specifically do not count as an infestation.
302.5 Rodent harborage. All structures and exterior property shall be kept free from rodent harborage and infestation. Where rodents are found, they shall be promptly exterminated by approved processes which will not be injurious to human health. After extermination, proper precautions shall be taken to eliminate rodent harborage and prevent re-infestation. Exception: The presence of squirrels or chipmunks on the exterior of a structure shall not constitute a rodent infestation.
Full Breakdown
5 of the Property Maintenance Code, Chapter 82, states plainly that "all structures and exterior property shall be kept free from rodent harborage and infestation," and where rodents are found, they must be "promptly exterminated by approved processes which will not be injurious to human health," followed by precautions to eliminate the harborage and prevent re-infestation. The section carves out one named exception: the presence of squirrels or chipmunks on the exterior of a structure does not itself constitute a rodent infestation. 17 requires operable basement windows to carry rodent shields, storm windows or other approved protection.
2 assigns responsibility for extermination to the owner, occupant or person in control of the premises, shifting it specifically to the owner where the infestation is caused by a defect in the structure itself.
Violations & Fines
Allowing rodent harborage or infestation to persist violates Section 302.5 and 308.1 and is prosecuted as a municipal civil infraction under Chapter 100, Municipal Civil Infractions, with each day of continued violation potentially treated as a separate offense under Section 106.2.
