New Haven, Conn., Code of Ordinances tit. V § 609
Carbon monoxide detectors, exemptions (New Haven Housing Code)
Operative Text
The following residential units shall not require carbon monoxide detectors: (1) A residential unit in a building that does not rely on combustion of fossil fuel for heat, ventilation or hot water. (2) Residential units in a building that does not pose a risk of carbon monoxide poisons due to sole dependence on systems that do not emit carbon monoxide.
New Haven, Conn., Code of Ordinances tit. V § 609 carves out two categories of residential units from the general carbon monoxide detector requirement. Units in buildings that heat, ventilate, and supply hot water entirely without burning fossil fuels are exempt, as are units in buildings whose systems pose no carbon monoxide risk because they emit none. The exemption is tied to the building's mechanical systems, not to individual tenant or landlord preference.
Plain English — not legal advice.
Under tit. V § 609, property owners managing buildings that run entirely on non-combustion systems—such as all-electric heating, ventilation, and hot water—may qualify for an exemption from the carbon monoxide detector requirement. Compliant operators typically document the building's energy systems to demonstrate that no fossil-fuel combustion occurs and that no carbon monoxide risk is present. Maintaining clear records of equipment type and fuel source helps support an exemption claim if questions arise during inspection.

Tit. V § 609 establishes that the carbon monoxide detector requirement does not apply to every residential unit—only those in buildings with combustion-based or carbon-monoxide-emitting systems must have detectors. If a tenant believes their building uses fossil fuels or other CO-emitting systems and lacks required detectors, they may consider contacting local housing or code enforcement authorities to inquire about compliance. Tenant-rights organizations in New Haven can also help residents understand whether the exemption applies to their building and what general options exist.
