Massive fires have recently erupted at wood-framed projects nationwide. All but one were under construction:
■ July 23, 2017 Waltham, Edison on the Charles, a 264-unit, wood-framed luxury apartment development under construction. The 10-alarm fire was ruled arson and caused $110 million damages.
■ June 28, 2017 Dorchester, Treadmark, a six-story, wood-framed development with 83 apartments under construction. The six-alarm fire was ignited by an exhaust pipe improperly installed too close to surrounding wood.
■ June 4, 2017 Quincy, Meriel Marina Bay, a project with 352 apartments and 20,000 square feet of commercial space. Part of the building burned; sprinklers were activated.
■ May 13, 2017 Emeryville, Calif. Fire destroyed a wood-framed apartment complex for the second time in less than a year. Officials ruled both fires arson.
■ May 8, 2017 Clarendon, Va. Ten at Clarendon, a 143-unit luxury residential apartment complex under construction. Small fire largely extinguished before firefighters arrive.
■ April 24, 2017 College Park, Md. Fuse 47, a 275-unit apartment building under construction, had begun pre-leasing for summer occupancy. Sprinklers had not yet been activated. Fire caused $39 million in damages. Two minor injuries reported.
■ March 20, 2017 Overland Park, Kan. Fire destroyed one apartment building and heavily damaged another in a 90-acre mixed use development. Embers from the blaze ignited 25 other structures south of the wood-frame complex, wreaking a $25 million loss.
■ March 16, 2017 Raleigh, N.C. The Metropolitan, a 240-unit wood-frame apartment complex under construction, caught fire and damaged several nearby buildings. Estimated losses exceed $50 million in the largest fire in downtown Raleigh in nearly a century. Officials are unable to determine a cause.
■ Feb. 4, 2017 Maplewood, N.J. The Avalon, a 235-unit complex under construction was heavily damaged in a six-alarm fire. About 100 units were gutted; the rest sustained water and smoke damage. With much of the physical evidence consumed in the fire, officials were unable to determine the cause.
■ Jan. 1, 2015 Edgewater, N.J. More than half of the 408 units at the Avalon Edgewater were leveled by fire, leaving 500 people homeless. The building was occupied when the fire, sparked by an unlicensed maintenance worker using a blowtorch, ignited a piece of insulation in the wall. The state’s building code did not require sprinklers in attics or spaces in floors and ceilings, leaving the flames to race through the lightweight wooden complex.
■ Dec. 8, 2014 Los Angeles. Fire destroyed the 526-unit Da Vinci Apartments as the wood-framed complex was under construction. Federal investigators ruled the case arson, sending the culprit to prison for 15 years. The fire heavily damaged nearby city property, and Los Angeles settled a lawsuit against the developer that alleged the company had inadequate fire safety prevention measures and insufficient security to stop intruders.
■ March 25, 2014 Houston, Calif. Wind-whipped fire leveled the 396-unit Axis Apartments. Investigators were unable to determine the cause. Dramatic video of the inferno went viral after a construction worker was plucked from a balcony by firefighters seconds before a wall collapsed.Kay Lazar can be reached at email@example.com Follow her on Twitter @GlobeKayLazar.
