What's different about smoke & co detector installation in Pasadena
Battery-only smoke alarms sold today must have sealed ten-year batteries. Gas furnaces, water heaters and ranges make CO alarms near bedrooms especially important. A licensed electrician can plan locations under current code. Permits come from the City of Pasadena's Planning and Community Development Department.
Many homes have original or patched wiring and small services. Electrification projects and rebuilding after the fire both bring panel and service upgrades.
Weather and the utility in Pasadena
Pasadena summers are hot and dry, and fall and winter bring Santa Ana winds that raise wildfire risk along the San Gabriel foothills. In January 2025, the Eaton Fire, driven by extreme winds, destroyed thousands of homes, most of them in unincorporated Altadena just north of Pasadena, with damage reaching some Pasadena neighborhoods too. Pasadena Water and Power, a city-owned utility, provides electricity in Pasadena and handles meters, service upgrades and solar interconnection, while Altadena is served by Southern California Edison. Earthquakes are another local hazard.
