The fire did some burn damage to a storage container in a parking lot near the Walgreens, but the flames did not reach the structure.
A pair of fires, one possible sparked by an unattended candle, left two residents with minor injuries and displaced several more, according to a Long Beach Fire Department official.
Fire crews evacuated a hotel near the Long Beach Airport after a small blaze set off an alarm and sent smoke wafting into a hallway.
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.
