Carbon monoxide alarms required per Fire Code of New York State §915
2025 RCNYS §R311.1 Carbon monoxide alarmsDescription
Carbon monoxide alarms must be installed per Section 915 of the Fire Code of New York State. Practically this means a CO alarm outside each separate sleeping area in the immediate vicinity of the bedrooms, on every story containing a fuel-burning appliance, and within bedrooms containing fuel-burning appliances (per IRC R315 / FC NY §915).
Why this exists
CO is invisible and odorless. Code requires CO alarms whenever fuel-burning appliances are present (gas range, gas water heater, furnace) OR an attached garage exists. Architects should default-include CO at every sleeping-area location during the alarm-location pass.
