SUMMARY
This bill modifies provisions of law governing the use of carbon monoxide detectors 
in this State. The bill does the following. 
1. It requires that, beginning January 1, 2027, a person install carbon monoxide 
detectors in the bedrooms and areas giving access to the bedrooms of any newly constructed 
occupancy in accordance with the Life Safety Code of the National Fire Protection 
Association as adopted by the Commissioner of Public Safety.
2. It modifies language to permit, rather than require, the Commissioner of Public 
Safety to adopt rules pertaining to carbon monoxide detectors. 
3. It modifies requirements related to carbon monoxide detectors in educational 
facilities to require an educational facility to install carbon monoxide detectors in 
accordance with the Life Safety Code of the National Fire Protection Association as 
adopted by the Commissioner of Public Safety, rather than requiring only a minimum of 
one carbon monoxide detector. 
4. It also clarifies that the Office of the State Fire Marshal and certain other state, 
county and municipal officials are authorized to enforce the provisions of law related to 
carbon monoxide detectors.
