A two-alarm commercial fire broke out in Sunnyvale early Tuesday, according to fire officials.
The blaze, which ignited just before 3:30 a.m., burned in the 500 block of Lakeside Drive and Titan Way, according to Battalion Chief Craig Anderson. Flames initially ignited inside one of the building's suites before spreading to the business next door.
The fire, which is believed to have started in an attic space, does not appear to be suspicious at this time, Anderson said.
Firefighters tried to fight the flames on the ground, but they forced to assume a defensive strategy and use suspended ladders, according to Anderson.
Further information was not available.
