crack in foundation. Should I worry?

[Rudky Martin]

Hi all,

The house that I want to purchase has some small cracks in the foundation in the garage. I am wondering if this is something I should worry about. I heard that horizontal cracks may be a big issue. However although it is horizontal, it is quite small ( around 1 feet) on the brick at the bottom of the garage. The property is in Bay Area, California. I attach photo in the message. Your opinions will be highly appreciated.

Thank you!!!
