New California Law Requires Carbon Monoxide Detectors

Real Estate Agent with PacifiCal Realty Group - Keller Williams

More than thirty people die from carbon monoxide poisoning each year. Most experts believe that these deaths are completely preventable with the right safety measures in place; specifically, on-site detectors that alert people when carbon monoxide levels increase to unsafe levels. In May last year, the state of California enacted a law requiring home owners to install carbon monoxide detectors in their single-family residences.

Detector Details

According to the bill, homeowners have until July 1st, 2011, to install a working carbon monoxide detector. Carbon monoxide detectors must be powered by a battery, or have a backup power source if connected to an outlet. They must also be certified by national testing labs (which will be stated on the packaging), and make an audible sound. Most detectors cost around twenty dollars.


The law does not affect everyone. It only applies to single-family residences with appliances that burn fossil fuels, or homes that have attached garages or fireplaces. The law also exempts state and local government property.


Homeowners who fail to comply with this law will be fined $200 after a thirty-day warning period. Additionally, homes in the process of being sold must have a working detector installed before ownership is transferred (much like smoke detectors).

Governments (city, county, state, national) are getting OUT OF HAND.  We're adults (at least I can say... I am) and we should be able to take care of ourselves.

Natural selection should have the opportunity to run its course.
