A fire that broke out on a fourth-floor balcony at a Hillsboro apartment complex Thursday afternoon burned into the wall framing behind it, forcing crews to cut open walls to fully douse the flames while dozens of residents sheltered from 91-degree heat in the building's air-conditioned community room. The blaze displaced seven adults and five children, and one person was hospitalized after being evaluated for a heat-related emergency.
Emergency dispatchers logged the call at 1:32 p.m. Thursday after people reported a fire alarm and visible flames on a fourth-story balcony in the 300 block of Southeast Edgeway Drive, according to KGW. The station reports that dispatchers upgraded the call to a first-alarm fire as arriving crews requested additional resources from Hillsboro Fire & Rescue and Tualatin Valley Fire & Rescue. The fire struck Wyndhaven Apartments at 230 SE Edgeway Drive, a 396-unit income-restricted community built in 2003 and 2004 that spans 12.2 acres across 11 three- and four-story buildings, according to RentCafe.
Wall-Opening Effort Chases Hidden Flames
Hillsboro Fire & Rescue crews knocked down the fire but then faced a labor-intensive follow-up: cutting into the wall behind the fourth-floor balcony to fully extinguish flames that had spread into the framing, according to a Hillsboro Fire & Rescue Facebook post. The department said the wall-opening process took considerable time, and the fire ultimately affected four apartment units. No firefighters were injured in the response, the department said.
The fire's cause remains under investigation, the department said. While investigators have not publicly determined how the fire started, its point of origin on an exterior balcony matches a pattern the National Fire Protection Association has tracked in outdoor cooking and open-flame fires. NFPA statistics published in May found that roughly 25% of home structure fires involving grills or open flames begin on a balcony or open porch, with 8% igniting exterior walls and 3% spreading directly into structural framing. The organization also found that U.S. fire departments respond to an average of 12,141 home fires tied to grills, hibachis, or barbecues each year, with activity peaking in the summer months.
Heat Advisory Complicated the Response
A National Weather Service heat advisory was in effect for Hillsboro on Thursday, with temperatures climbing to 91 degrees, conditions that added risk for both fleeing residents and firefighters working in full gear. Roughly 40 to 50 residents were temporarily moved to the apartment community's air-conditioned community room, where they received water and shelter, per the fire department's Facebook post. Two residents were assessed on scene for heat-related emergencies, and one was taken to a hospital for further care.
Under Section 308.1.4 of the 2022 Oregon Fire Code, charcoal burners and other open-flame cooking devices are barred from combustible balconies or from within 10 feet of combustible construction in multi-family buildings that lack automatic sprinkler protection, according to the International Code Council. The rule exists because embers or flare-ups on an elevated deck can quickly catch exterior siding or structural wood, a risk fire officials say is compounded in dense, multi-story housing like Wyndhaven.
Multi-Agency Response and Displacement Aid
Tualatin Valley Fire & Rescue crews responded alongside Hillsboro firefighters under the two agencies' standing mutual aid agreement, which routinely pairs the departments on structure fires across Washington County. AMR Washington County provided medical support at the scene, and the Hillsboro Police Department and Hillsboro Public Safety Chaplains also assisted, according to the fire department's Facebook post.
The American Red Cross is helping relocate the seven adults and five children displaced by the fire. The Red Cross Cascades Region provides emergency shelter, financial assistance, clothing, and other recovery support to families displaced by home fires across Oregon and Southwest Washington, with Disaster Action Teams responding locally around the clock to address immediate needs after a fire.
Thursday's fire adds to a string of recent multi-family blazes handled jointly by Hillsboro Fire & Rescue and Tualatin Valley Fire & Rescue in Washington County. In March, the two agencies jointly battled a Beaverton apartment fire on NW Cornell Road that damaged stairwells and upper-floor units and similarly required multi-unit salvage work and displacement support.
