Berkeley allows limited home occupations in residential zones under BMC Title 23, subject to no-impact standards including no employees, no customer visits, and no visible signs.
Berkeley Municipal Code Title 23 (Zoning) permits home occupations as accessory uses in residential districts provided the activity is clearly incidental to residential use. Standards typically include: no non-resident employees, no retail sales on premises, no external evidence of the business (no signs, no storage, no extra traffic), no more than 25% of the dwelling used for the business, and no equipment generating noise, vibration, odor, or electrical interference audible or visible beyond the dwelling. A Zoning Certificate from the Berkeley Planning Department is required before starting, and a City of Berkeley Business License is required for any business activity. Certain uses (auto repair, commercial kitchens, firearms sales) are prohibited as home occupations.
