Summary
Under Santa Rosa Zoning Code Section 20-42.070, a home occupation is allowed in any residential zone only when it is clearly secondary to the primary residential use and will not change the residential character of the neighborhood. Several specific uses - including auto repair, kennels, pet grooming, animal hospitals, bee keeping, weapons or ammunition sales, welding shops, and woodworking or metal shops - are categorically prohibited as home occupations.
51035. (a) A city, county, or city and county shall not prohibit a cottage food operation, as defined in Section 113758 of the Health and Safety Code, in any residential dwellings, but shall do one of the following: (1) Classify a cottage food operation as a permitted use of residential property for zoning purposes. (2) Grant a nondiscretionary permit to use a residence as any cottage food operation that complies with local ordinances prescribing reasonable standards, restrictions, and requirements concerning spacing and concentration, traffic control, parking, and noise control relating to those homes. Any noise standards shall be consistent with local noise ordinances implementing the noise element of the general plan. (3) Require any cottage food operation to apply for a permit to use a residence for its operation. The use permit shall be granted if the cottage food operation complies with local ordinances, if any, prescribing reasonable standards, restrictions, and requirements concerning the following factors: spacing and concentration, traffic control, parking, and noise control relating to those homes. (c) Use of a residence for the purposes of a cottage food operation shall not constitute a change of occupancy for purposes of the State Housing Law, or for purposes of local building and fire codes. (d) Cottage food operations shall be considered residences for the purposes of the State Uniform Building Standards Code and local building and fire codes.
Full Breakdown
070. The City's published Home Business Permits page and FAQ summarize the operative standards: the business must be operated by a resident of the home, be clearly secondary to the home's use as a residence, not create noticeable noise, odors, dust, or other impacts, have no outdoor storage of business materials, and not involve regular outdoor work activity. The City's published prohibited-use list, repeated in both the official Home Business page and the City's FAQ, expressly bars the following from operating as home occupations: animal hospitals; automobile or vehicle repair shops; bee keeping; kennels, including pet day care; pet grooming shops; raising of animals for commercial purposes; weapons or ammunition sales; welding shops; and woodworking or metal working shops.
Cottage food operations are governed separately by California Government Code Section 51035, which expressly preempts municipal bans: cities must either classify cottage food operations as a permitted use of residential property or grant a non-discretionary permit subject only to reasonable standards on spacing, traffic, parking, and noise. State law also provides that use of a residence for a cottage food operation does not constitute a change of occupancy under the State Housing Law or local building and fire codes (Gov. Code 51035(c) and (d)). 030. Live/work units, accessory dwelling units, and short-term rentals all have separate standards in Chapter 20-42 and Chapter 20-28.
Violations & Fines
Operating a prohibited use (e.g., auto repair, pet grooming, woodworking) as a home occupation, or operating a permitted home occupation in a manner that materially impacts the neighborhood (noise, odors, traffic, outdoor storage), is a zoning violation under Title 20. The Code Compliance Division typically issues a notice of violation requiring the operator to cease the use, and unresolved violations may be referred for administrative citations, fines, and abatement, including revocation of any associated Minor Conditional Use Permit. State preemption protects cottage food operations from outright bans, but local performance standards (parking, traffic, signage, noise) remain enforceable.
