Chico Home Inspector – Smoke Detector Placement

Several times a week I get calls from clients and real estate agents asking for clarification on where smoke detectors should be placed in a home. You can refer to the drawing below to get you started.

Commencing July 1, 2014, all smoke alarms including combination smoke alarms, that are solely battery powered and installed in California shall contain a nonreplaceable, nonremovable battery that is capable of powering the smoke alarm for at least 10 years.

Required smoke detector locations are as follows:

  • One smoke detector in each sleeping room.
  • One smoke detector in each hallway leading to a sleeping room.
  • One smoke detector in the common area of the home.
  • One smoke detector on each floor of a multi-story home (including on in the basement).

I also suggest installing a smoke detector in the garage and laundry room, as many home fires originate in these areas of the home.

Tip:  Placing a combination smoke and carbon monoxide alarm such as the Kidde Combination Alarm in the hallway also covers you for California’s Carbon Monoxide Alarm requirements.

Choosing the right home inspector can be difficult. Unlike most professionals you hire, you probably won’t meet me until your inspection appointment--after you've hired me. Furthermore, different inspectors have varying qualifications, equipment, experience, reporting methods, and pricing.

One thing that’s certain is that a home inspection requires a lot of work. Ultimately, a thorough inspection depends heavily on the individual inspector’s effort. If you honor me by permitting me to inspect your new home, I guarantee that I will give you my very best effort.
