Grounds, buildings and structures shall be maintained free of insect, vermin and rodent harborage and infestation.

Full Breakdown

Town Code § 157-40, 'Insect, vermin and rodent control,' sits in Chapter 157's Article VI, Property Maintenance Requirements, and applies town-wide to residential premises under § 157-3. ' Subsection C imposes a seasonal window: 'From May 1 to October 1, entrances to residential buildings shall be provided with self-closing-type devices or screens, and windows and other openings used for ventilation shall be appropriately screened,' though upper-story rooms in multiple dwellings high enough to be free of mosquitoes and flies are exempted from the screening requirement.

This sits alongside § 157-39C, requiring accessory structures be kept free of conditions detrimental to safety or health, and § 157-41, barring the storage or accumulation of garbage or refuse in public halls and stairways of multiple dwellings, both of which compound infestation risk if ignored. ' The Building Inspector enforces § 157-40 as part of the housing standards under § 157-43 and § 157-44, and may order in writing the remedying of any infestation condition found, with the power to order vacation of a unit rendered unfit for habitation under § 157-44C(3) and to act immediately where the condition poses an immediate hazard under § 157-44D.

Violations & Fines

A violation of § 157-40, uncontrolled rodent or vermin harborage, unscreened basement openings, or missing seasonal entrance screening, is a Class B misdemeanor under § 157-47A, punishable by a fine of up to $2,000 and/or imprisonment of up to three months, with each day the condition continues counted as a separate offense. On registered rental premises, an infestation condition found at the biennial inspection must be corrected within 10 days under § 157-65B or the owner faces a further violation.
