A second alarm fire inside a condo in a Coronado apartment building was caused by a construction accident.
Coronado Police said the fire began around 2:45 p.m. on the 1000 block of 1st Street at the Landing Condos. The location is right by Centennial Park facing the San Diego Bay, near the eastern end of Orange Avenue.
Plumbers using a welding torch sparked a fire in the wall between two third floor condominiums.
Black smoke could be seen coming from one of the units when crews arrived on scene.
Six units sustained smoke, fire and water damage.
Police initially said the fire appeared to have started near an electrical outlet.
The bulk of the fire was knocked down by approximately 3:30 p.m. A second alarm was called out in an abundance of caution, police said.
Some residents left their units and went to Centennial Park to be out of the way of firefighters. But there were no forced evacuations.
There were no injuries reported.
Northbound traffic on Orange Avenue at 1st, 3rd streets and D Avenue was shut down. Authorities also closed down traffic on 1st Street at C Avenue.
Motorists were asked to avoid the area while firefighters were on scene.
