The Carbon Monoxide Poisoning Prevention Act (Senate Bill 183) is a two part law that states the detectors must be installed on or before July 1, 2011, in single-family dwelling units.
The law goes on to state that single family homes with fossil-fuel burning appliances and/or an attached garage MUST have the detectors installed prior to sale. The Transfer Disclosure Statement used in real estate transactions has been updated to state the presence or absence of the detectors.
All other dwelling units, such as apartments or multi-family dwellings, have until July 1, 2013, to comply.
How easy is it to comply with the law? As easy as popping down to your local Home Improvement Store and buying an inexpensive plug-in unit for less than the cost of a night out at the movies.
