Why carbon monoxide detector installation comes up in San Jose
California has required carbon monoxide alarms in homes with fuel-burning appliances or attached garages since 2011, and most San Jose tract homes have both: gas furnaces and water heaters and an attached two-car garage. Alarms belong outside each sleeping area and on every level. Combination smoke and CO alarms simplify the job, and renovations under permit typically require hardwired, interconnected units.
When homes are sold, sellers must disclose compliance. Permits come from the city's Planning, Building and Code Enforcement department. Garage conversions and accessory dwelling units need their own alarms too.
- California requires smoke alarms in homes and, since 2011, carbon monoxide alarms in homes with fuel-burning appliances or attached garages, and new or replacement battery-only smoke alarms must have sealed ten-year batteries.
