Four people escaped a burning two-story duplex in Petaluma on Sunday afternoon even though the smoke alarms inside never went off, officials said. Firefighters arrived at the Park Place Drive home around 4:30 p.m. to find heavy fire tearing through the first floor, and by the time crews had it under control roughly 20 minutes later, both units of the duplex had been deemed uninhabitable.
As reported by The Press Democrat, flames traveled from the first floor up the exterior of the structure and into the attic, exposing an adjoining unit and a nearby duplex before firefighters could stop the spread. Petaluma firefighters were joined by crews from the Sonoma County Fire District and Gold Ridge Fire Protection District in a mutual-aid response.
All four residents made it out of the building, along with a cat and two geckos. One firefighter reported a minor back sprain during the response, according to the same account. Officials said they did not know how the residents first learned of the fire, since the smoke alarms inside the unit were not working and never alerted anyone inside.
Officials Urge Residents to Test Alarms Regularly
In the aftermath, officials reminded residents to make sure their smoke detectors are working properly and to check them regularly, the station's report noted. The reminder lands against a backdrop of state law that puts the burden of maintaining those alarms squarely on property owners. Under California Health and Safety Code Section 13113.7, landlords of residential rental properties must install State Fire Marshal-approved smoke alarms in every bedroom, in hallways outside sleeping areas, and on every level of a dwelling, according to FindLaw.
California law also requires landlords to confirm that alarms are operable at the start of a tenancy, and since July 2014, any newly installed battery-powered smoke alarm must contain a non-removable, sealed 10-year battery, per Advantage Property Management Services. Tenants, for their part, are legally required to notify landlords if an alarm stops working during their tenancy. Property owners who fail to comply with the state's residential fire safety rules face an infraction punishable by a maximum fine of $200, according to the California Department of Forestry and Fire Protection.
Older East Petaluma Housing Stock Raises Questions
The construction dates of multi-unit residential properties along Park Place Drive are not established here. Without that information, it is not possible to determine whether some East Petaluma duplexes may still rely on older battery units that require manual upkeep rather than the sealed, long-life alarms now standard in newer construction.
The stakes of a malfunctioning alarm are steep. A May 2024 report from the National Fire Protection Association examining data from 2018 to 2022 found that nearly three out of five U.S. home fire deaths occurred in properties with no smoke alarms or with alarms that were not functioning. The article does not establish how quickly occupants may need to escape once flames ignite.
Cause Still Under Investigation, Red Cross Steps In
The cause of the fire remained under investigation as of Monday afternoon, officials said. The American Red Cross has provided assistance to the four displaced residents, and the organization's Northern California Coastal Region reported in May that its Sound the Alarm initiative installed 1,128 free smoke alarms across 459 Bay Area households during its spring campaign, which included a community installation event in Petaluma in April.
Fire officials estimated the blaze caused at least $525,000 in damage to the home. The Petaluma Fire Department, which operates out of three stations and handles more than 7,000 emergency calls a year, protected the adjoining unit and neighboring homes from the flames during the response, officials said. The article does not document a specific broader investment in the city's emergency infrastructure.
