Overview

Many low-impact home businesses are allowed in residential zones if they meet conditions such as no external signage, no customer traffic beyond occasional visits, and no on-site manufacturing or storage that alters the residential character. For city guidance and specific zoning conditions see the Development Services home-based business information page City of San Diego - Home-Based Business[1]. For business tax certificate requirements, see the Treasurer's Business Tax Certificate information Business Tax Certificate[2].

What counts as a home business

  • Clerical, administrative, professional or crafts done indoors with no visible change to the residence.
  • No on-site retail or wholesale operations that attract regular customer visits.
  • No external storage of materials or equipment that changes the residential appearance.
  • No more than occasional client or delivery visits as defined by local zoning rules.
If you expect regular customer traffic or employees at the residence, check zoning early.
