"temporary" rules for carbon monoxide alarms. Comments are due by October 1 2010 and permanent rules go into effect 12/1/2010.
Last year, the Oregon legislature passed legislation requiring carbon monoxide alarms in most homes that contain a heater, fireplace, appliance or cooking source using natural gas, coal, kerosene, wood or other fuels that emit carbon monoxide through combustion. The law also applies to residences with attached garages that have an opening directly into a living space. See the rules for additional details.
The effective date for new tenancies: July 1, 2010 and the effective date for all existing tenancies: April 1, 2011.
In Washington State, July 1 2011 is the deadline for installing carbon monoxide alarms in all multifamily units - no exceptions. The effective date for new construction: January 1, 2011. Read the Washington State rules here.
