About a dozen stores were allowed to reopen Thursday as the city attempts to recover from the 7.2-magnitude quake that killed two people in nearby Mexicali, Mexico.
Pedestrians are returning to the area, though streets remain closed to vehicles and chain link fences still surround damaged buildings.
About two dozen buildings remained closed due to serious damage. City Manager Victor Carrillo says some may be demolished.
Grocery store owner Eduardo Lopez spent the morning calling employees back to work. His building escaped major damage but he says the closure cost him thousands of dollars.
Calexico is about 120 miles east of San Diego.
