Killingly, Conn., Code of Ordinances ch. 4, art. III § 4-60
Ventilation standards
Operative Text
Section 4-60 Ventilation standards A. Every habitable room shall have at least one (1) window or skylight facing directly outdoors which can easily be opened or closed or such other device as will adequately ventilate the room, provided that, if a habitable room is connected to a room or area used seasonally, then adequate ventilation must be possible through this interconnection. The total of operable window area in every habitable room shall be equal to at least fifty percent (50%) of the minimum window area size or minimum skylight-type window size as required in § 4-59, except where there is supplied some other device affording adequate ventilation and approved by the Building Official. B. Interior climate-control facilities (heating, cooling and/or humidity) shall be maintained and operated in a continuous manner and in accordance with the design capacity of the installed equipment. When such equipment is in-operative because of power or mechanical failure, alternative provisions for fresh air ventilation of each dwelling or dwelling unit shall be provided. C. Every bathroom and water closet compartment and non-habitable room used for food preparation shall comply with the ventilation standards for habitable rooms contained in this section, except that no window or skylight shall be required in such rooms if they are equipped with a ventilation system in working condition which is approved by the Building Official.
Section 4-60 of Killingly's Rental Housing Standards Code establishes minimum ventilation requirements for residential spaces. Every habitable room must have an openable window, skylight, or approved alternative device providing adequate airflow, with operable window area meeting at least 50% of the minimum window size set by § 4-59. Bathrooms, water closet compartments, and food-preparation rooms must meet the same standards, though a Building Official–approved mechanical ventilation system can substitute for a window. When climate-control equipment fails due to power or mechanical issues, alternative fresh-air ventilation must be provided in the interim.

Operators of rental housing in Killingly should ensure that every habitable room covered by § 4-60 contains an openable window or skylight with operable area equal to at least 50% of the § 4-59 minimum, or an alternative ventilation device approved by the Building Official. Compliant operators keep interior climate-control systems running continuously at design capacity and have contingency plans for fresh-air ventilation whenever mechanical or power failures occur. Bathrooms and food-prep rooms without windows must be equipped with a functioning, Building Official–approved mechanical ventilation system to satisfy § 4-60(C).

Under § 4-60 of Killingly's Rental Housing Standards Code, tenants have a right to habitable rooms with adequate ventilation through openable windows, skylights, or approved devices, and to functioning climate-control systems that include backup fresh-air provisions during equipment failures. If a rental unit appears to lack the required ventilation — such as sealed or inoperable windows, a broken exhaust system in a bathroom, or no alternative airflow during a heating or cooling failure — tenants may consider documenting the condition and contacting Killingly's local code enforcement or building department to report a potential violation. Tenant-rights organizations can also help explain what options may be available when a landlord does not address ventilation deficiencies covered by § 4-60.
