TAMPA, Fla. – An electrical failure caused a two-story, multi-unit apartment building to go up in flames Monday, leaving tenants without a home.

Jason Penny with the Tampa Fire Department said the fire, which destroyed 10 units, started on the outside of an enclosed patio and upwards into the eaves, spreading to the common roof of Knollwood Manor Apartments on Rockaway Court.

Damage to the building is estimated at more than $350,000, Penny said.

Penny said one tenant was awoken by the sound of her smoke alarm, then other tenants helped spread the word to ensure everyone got out safely.

Crews contained the fire to the single building without damage to surrounding structures, Penny said.

The American Red Cross is assisting displaced residents. No injuries were reported.
