The fire at 155 S. Estep was first reported just before 3 p.m. Monday.
The home was reported to be 50% involved when firefighters arrived, with power lines down and the residents out of the home.
Very quickly, the fire spread into nearby wildland and began threatening other structures.
That prompted police to begin evacuations on Estep, First, Second, Lakeview and Crawford streets.
As of just after 3:15 p.m., a total of three homes were on fire. In addition to the original home, there were homes burning on Lakeview Street, near the Lake County Courthouse, and Second streets.
At 3:19 p.m., in support of Lakeport Fire, Lake County Fire issued a call for an immediate need in-county strike force of at least three engines of any type to respond to the fire.
Air support from Cal Fire also was requested, based on radio reports.
Lake County Fire reported that Mendocino County also is sending three engines to assist.
There were spot fires reported on Second and N. Estep streets and Lakeport’s roads crew parked a truck at Third and Estep streets to keep people out of the area.
Just before 3:40 p.m., the task force was canceled and it was reported that forward progress had stopped on the wildland fire aspect of the incident.
At that time, Cal Fire’s air attack arrived and noted the fire appeared to be contained within the original block, with no spot fires at that point.
At 3:49 p.m., incident command said the fires in the three structures had been knocked down and they were in mop up.
It was reported that one home was heavily damaged, a second had exterior damage and a third structure, an outbuilding, also had exterior damage.
