Summary
In unincorporated San Diego County, a home occupation is a permitted accessory use by right under Zoning Ordinance Section 6156.m when its conditions are met: there is no separate discretionary home-occupation permit, and the County does not currently require a business license for cottage food operators in the unincorporated area.
6156.m Home Occupations. Home occupations, including in-home offices, shall be permitted in compliance with the following conditions:
1. There shall be no exterior evidence of the conduct of a home occupation.
2. A home occupation shall be conducted entirely within a dwelling, or an attached garage. However, a Cottage Foods Operation, as defined by Health and Safety Code Section 113758, shall be conducted only within a dwelling that contains the dwelling’s kitchen and shall not be allowed in a garage or other accessory building.
3. Electrical or mechanical equipment which creates visible or audible interference in radio or television receivers or causes fluctuations in the line voltage outside the dwelling unit shall be prohibited.

Full Breakdown
Unlike many incorporated cities that issue a discretionary 'Home Occupation Permit,' the unincorporated County allows home occupations as a by-right accessory use. m states that home occupations, including in-home offices, 'shall be permitted in compliance with the following conditions,' meaning no separate planning permit or hearing is required as long as the operator continuously satisfies the listed standards (conducted inside the dwelling/attached garage, no exterior evidence, no more than one non-resident employee, 125-cubic-foot storage cap, required parking maintained, no excess traffic, no off-premise nuisance, and no on-premise sale of goods except as allowed for a permitted Cottage Food Operation).
The County's Cottage Food zoning guidance confirms that for the unincorporated County 'a business license is not required at this time,' though cottage food operators must obtain a stamp approval from County Planning & Development Services / Building Division. y (now affected by state preemption, see daycare). Operators should still verify their parcel's zoning through the County GIS and confirm that their specific activity qualifies as a home occupation, since some uses are not permitted as home occupations and may require a Minor Use Permit or other approval.
Violations & Fines
A home occupation that stops meeting the Section 6156.m conditions loses its by-right status and becomes a zoning violation subject to County code enforcement. Activities that do not qualify as home occupations may require separate discretionary permits.
