San Diego's Home Business: The Rules That Matter

Every city handles home business a little differently. In San Diego, California, there are 5 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Cottage Food Operations

Cottage food operations in San Diego require a permit from the San Diego County Department of Environmental Health. Under California's Cottage Food Law (AB 1616/AB 1147), Class A operators sell directly to consumers from their home, while Class B operators may sell at farmers markets, through third-party retailers, and online. Occasional transport of goods for off-site sale is permitted. Internet sales are not considered on-premise sales.

Key details: Permit: County Department of Environmental Health permit required. Class A: Direct sales from home to consumer. Class B: Farmers markets, retail, online sales permitted. Revenue Cap: $75,000/year (Class B) per CA law. State Law: CA HSC §§113758, 114365 (Cottage Food Law).

Selling non-permitted foods: cease and desist. Exceeding revenue caps: commercial kitchen requirement. Labeling violations: warnings then fines.

Home Daycare

Small family day care homes (up to 8 children) are permitted as an accessory use in residential zones in San Diego. Large family day care homes (9-14 children) require an Administrative Permit per the Land Development Code. The Director may grant the permit upon finding the daycare will not adversely affect neighborhood character. California state licensing through Community Care Licensing Division is also required.

Customer Traffic Restrictions

SDMC Section 141.0308 limits home occupations to one customer on the premises at a time, by appointment only, between 7 AM and 7 PM. No deliveries by commercial vehicles larger than one-ton capacity. Business must not generate traffic noticeable above normal residential levels.

Compared to other cities, San Diego takes a harder line on customer traffic restrictions. The enforcement and penalty structure reflects that.

Zoning Restrictions

SDMC Section 141.0308 permits home occupations as accessory uses in all residential zones. The business must not change residential character, generate excessive traffic, noise, or odors. Only residents may operate. One non-resident employee permitted on-site Monday-Saturday 7 AM-7 PM.

Key details: Permitted: Accessory use, all residential zones. Employees: 1 non-resident max on-site. Hours (Employee): 7 AM-7 PM Mon-Sat. Signs: Not permitted. Code Section: SDMC 141.0308.

Key details: Exterior Signs: Prohibited. Window Signs: Prohibited. Banners: Prohibited. Online Presence: Not restricted. Code Section: SDMC 141.0308.

Code enforcement notice to remove signage. Non-compliance may result in citation and fines. Persistent signage violations may trigger review of the home occupation use.

This is not one of those rules that cities tend to ignore. San Diego actively enforces its signage rules requirements.
