Zoning Use Question for Berkeley, CA

[Nicholas Leone]

Hello everyone. I'm eyeing a property in Berkeley, CA for Multifamily use. The property is zoned "C-SA" for South Area Commercial. It appears that there is currently residential use on the property but I'm not sure if it is allowed. I don't want to buy a building only to find out that multifamily use is not allowed. Does anyone have any experience or better knowledge of Berkeley Land Use or the C-SA zoning? Looking for some insight on BP before a hire an attorney to research this. Thank you!
