Beverley "B.J." Johnson said her real estate office at Prudential California Real Estate at Marguerite Avenue and East Coast Highway was affected.
"We had to evacuate the block because of wires falling down and the…fire," she said in an e-mail.
Media representatives with SoCal Edison have not yet been able to provide information about what caused the downed lines.

Komen Cancer runners victims of vehicle burglaries
A burglar broke into three cars and stole $2,709 in items from five people who had parked at Corona del Mar High School while they participated in last weekend's 19th annual Susan G. Komen Orange County Race for the Cure.
The five victims had items in three cars, which were broken into between 8:20 and 10:40 a.m. Sept. 26 at the school at 2010 Eastbluff Drive.
The lot was a designated parking area for the run, according to the event's website.
Items stolen included multiple purses, cash, ID and credit cards, wallets, cell phones, glasses, checks and Disneyland tickets, said Officer David Sanborn. The burglar also caused about $400 in damage, according to a police report.
The valuables apparently were clearly visible from outside the vehicles, Sanborn said. Police urge people to store valuables in their locked trunks before arriving at a destination, and to make sure cars are locked.
The Race for The Cure had 24,000 participants this year, raising millions of dollars in an effort to end breast cancer.
