The boat fire sent smoke into the air near the Queen Mary before firefighters arrived and doused it, according to authorities.
No one was injured or displaced because of the fire and investigators are still working to determine the cause.
Members of the local diving community gathered Thursday night at the Deep Blue Scuba and Swim Center in Belmont Shore to hold a vigil for the 34 people who died in a boat fire off the coast of Santa Barbara.
The Coast Guard called off its rescue operation Tuesday after determining there were no more survivors on a boat packed with scuba divers that caught fire near an island off the Santa Barbara coast.
Five crew members who jumped off the boat were rescued, and Lt. Cmdr. Matthew Kroll told The Associated Press the Coast Guard was searching for others who may have been able to escape the same way.
The man got up to move another motorhome he had in the area, and as he was working on the engine, trying to get it started, some fuel ignited, the LBFD said.
Photos from the scene show the roof and front rooms heavily damaged.
It’s so far unclear how the fire started, but it closed the street at Orange Avenue and Del Amo Boulevard for nearly two hours.
The fire was contained to the attic, but it set of sprinklers throughout the building.
One person was sent to the hospital with burns when two separate fires charred a one-story house and clogged a beachfront high-rise with smoke.
