SAN FRANCISCO — San Francisco fire officials say crews have contained a large blaze that damaged two buildings in the city's Mission District.

Firefighters were able to get a handle on the blaze about three hours after it began. At least two firefighters and two civilians have been treated for smoke inhalation.

Mayor Ed Lee says he was grateful that there were no serious injuries reported. A second building was also damaged.

San Francisco Fire Department spokeswoman Mindy Talmadge says more than 100 firefighters were battling the blaze, which started shortly after 1 p.m.

The fire apparently began inside a retail store in a two-story building and quickly grew from two to five alarms in an hour.

Fire Chief Joanne Hayes-White said fire inspectors came out to the store at least twice since 2009 following customer complaints of overcrowding.

No violations were issued.
