An under construction house was destroyed and two adjacent homes were damaged by an early morning fire that investigators say is arson. The fire marks the second arson of an under construction building in the area within a 24 hour span. Firefighters were called to the 5712 N.E. 47th Street at about 1:30 a.m. Thursday for reports of flames coming through the roof of a two-story house that was under construction, according to the Vancouver Fire Department. Heavy smoke was seen from several miles away, the agency said. It took a crew of 24 firefighters about 30 minutes to bring the fire under control. No injuries were reported. Clark County Assistant Fire Marshal Richard Martin said the fire has been ruled an arson and that the damage from the destroyed house and the two singed adjacent houses totaled about $600,000.
