The first blaze erupted just after 2:30 a.m. Sunday at a home on Southeast 267th Place near Kent. Firefighters say it made its way into the attic, and they had to pull down the ceiling to fight it.
Three people inside were able to make it out OK. Investigators say a discarded cigarette butt caused the fire.
About an hour later, around 3:30 a.m., a man who lives in West Seattle was able to escape after fire broke out at his home.
Firefighters were called to his home, in the 5200 block of 45th Avenue Southwest, after receiving 911 calls from neighbors. They were able to prevent the fire from spreading to other nearby homes.
Officials say the man had a fire going in his fireplace when flames jumped out and caught his carpet on fire, which quickly spread through the house. He sustained only a minor burn in the blaze.
At about 4:30 a.m., a fire flared up at an Edmonds home, causing more than $250,000 in damage.
Neighbors called 911 to report the fire at a single-story house in the 1000 block of Ninth Ave. S., and crews quickly responded, said Leslie Hynes of Snohomish County Fire District 1.
No one was inside the house at the time of the fire and there were no injuries. Neighbors told firefighters renters had moved out of the house sometime within the past few weeks, and the homeowners were fixing up the house so they could move in.
Investigators have not yet determined how that fire started. This is the second fire at this house in less than a month. A neighbor and the tenant extinguished that fire before firefighters arrived. Damage was minimal, and investigators were unable to determine how that fire started.
"It's too early for investigators to say if today's fire is suspicious or if it is somehow related to the previous fire," Hynes said.
About three hours later, at around 7:25 a.m., flames erupted at an abandoned mobile home in the Martha Lake area east of Lynnwood was destroyed by fire this morning.
No one was inside the home at the time of the fire. Firefighters had the fire out in about 15 minutes. No one was injured.
"Most of the exterior walls were still standing, but the fire gutted the inside of the mobile home and burned through the roof," Hynes said.
The Snohomish County Fire Marshal's Office investigated the fire and determined it was most likely started by transients who were frequently seen by neighbors inside the mobile home.
