You will need to apply for a Home Occupation Permit from the Planning Division if your home in a residential zone is the base of operation for your business - serving as a mailing address, office, shop, or related use - even if you do work in other locations. The property owner must sign the permit application, consenting to your home occupation. See the Home Occupation Permit page for more information.
To report an illegal home business, call Neighborhood Services at 209-664-7348, or complete the online citizen report form.
