The Short Version
Berkeley Zoning Ordinance Chapter 23C.16 allows home occupations in all residential zones subject to specific performance standards. Home businesses must be clearly incidental and secondary to the residential use of the dwelling, conducted entirely within the residence or an approved accessory structure, and may not alter the residential character of the property. A Zoning Certificate (administrative approval) is required before commencing a home occupation. The business must be operated by residents of the dwelling, with no more than one non-resident employee permitted.
Full Breakdown
Berkeley Zoning Ordinance Chapter 23C.16 establishes the standards for home occupations in residential zoning districts. The intent is to allow residents to conduct business activities from home while preserving the residential character of neighborhoods.
To qualify as a home occupation, the business must meet all of the following performance standards:
1. The business must be conducted entirely within the principal dwelling unit or an approved accessory structure (such as a detached garage or studio). 2. No more than 25% of the total floor area of the dwelling unit may be devoted to the business activity. 3. The home occupation must be clearly incidental and secondary to the residential use of the property. 4. No more than one non-resident employee may work on the premises at any time. 5. No exterior alterations, signage (other than as separately permitted), or other visible evidence of the business may be apparent from the public right-of-way. 6. The business may not generate noise, vibration, odors, electrical interference, or other impacts beyond what is normal for a residential use. 7. No retail sales of goods to walk-in customers on the premises (online sales with shipping are permitted). 8. No storage of hazardous materials, commercial vehicles, or equipment beyond that customarily found in a residence.
Certain business types are expressly prohibited as home occupations regardless of compliance with performance standards, including automotive repair, vehicle body work, manufacturing or assembly operations, medical or dental offices, animal grooming or boarding, and any use requiring a California Department of Alcoholic Beverage Control license.
Applicants must obtain a Zoning Certificate from the Berkeley Planning Department before commencing the home occupation. The application is reviewed administratively (no public hearing required) for compliance with the performance standards. A separate City of Berkeley business license is also required. Contact the Planning Department at (510) 981-7410 for applications.
What Happens If You Violate This?
Operating a home occupation without a Zoning Certificate or in violation of the performance standards is a zoning violation. The Planning Department issues a notice of violation with a compliance deadline, typically 30 days. Continued violations may result in administrative citations of $100 per day, revocation of the Zoning Certificate, and potential misdemeanor charges under the zoning enforcement provisions of BMC Title 23. The city may also require cessation of the business activity.
