Bristol, Conn., Code of Ordinances ch. 12 § 12-79
Ventilation standards
Operative Text
(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 openable window area in every habitable room shall be equal to at least forty-five (45) per cent of the minimum window area size or minimum skylight-type window size as required in section 12-78 , except where there is supplied some other device affording adequate ventilation and approved by the director of health. (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 inoperative 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 nonhabitable 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 director of health.
Bristol Code of Ordinances ch. 12, art. V § 12-79 establishes minimum ventilation standards for residential spaces. Every habitable room must have at least one openable window, skylight, or approved alternative device providing adequate airflow, with openable area meeting at least 45 percent of the minimum window size required under § 12-78. Climate-control systems must run continuously at design capacity, and when they fail, alternative fresh-air ventilation must be provided. Bathrooms, water closet compartments, and food-preparation rooms face the same standards, though an approved mechanical ventilation system can substitute for a window or skylight in those spaces.
Plain English — not legal advice.
Operators of residential properties in Bristol must ensure that every habitable room complies with the openable-window or approved-device requirements of § 12-79, with openable area equal to at least 45 percent of the minimum window size set by § 12-78. Climate-control equipment must be kept in continuous, fully functional operation at its design capacity; when a power or mechanical failure occurs, compliant operators arrange alternative fresh-air ventilation for each affected dwelling unit. Bathrooms and food-preparation rooms without windows must be equipped with a director-of-health-approved ventilation system that is kept in working condition.
General guidance for property managers — not legal advice for your specific situation. Consult an attorney for advice on your case.
Under Bristol Code of Ordinances ch. 12, art. V § 12-79, tenants are entitled to habitable rooms with adequate ventilation through openable windows, skylights, or approved devices, and to functioning climate-control systems or alternative fresh-air provisions when those systems fail. If a rental unit appears to lack the required ventilation — for example, a bathroom with no window and a broken exhaust fan — that condition may constitute a code violation that can be raised with local housing or health authorities. Tenants who believe their unit falls short of the § 12-79 standards may consider contacting Bristol's director of health, a local tenant-rights organization, or a housing attorney to understand available options.
