Summary
Unincorporated Riverside County allows home occupations by right in residential zones, but confines the business entirely inside the dwelling with no employees, no accessory-structure use, and one 2-square-foot sign.
Home occupations means those uses that are customarily conducted in a residence, provided such uses must be incidental and secondary to the principal use of a dwelling as a residence... A home occupation shall be conducted entirely within the dwelling... shall not be conducted in an accessory structure and there shall be no storage of equipment or supplies in an accessory structure or outside building... No signs other than one unlighted identification sign, not more than two square feet in area, shall be erected on the premises.

Full Breakdown
County Code Section 17.04.120 permits home occupations as an accessory use across residential zones without a separate permit, so long as the business stays incidental and secondary to the home's residential use. No non-resident employees are allowed (family day care aides are the sole exception), the business must run entirely inside the dwelling with zero storage in garages, sheds or yards, the home's residential look can't change inside or out, and only one unlighted sign up to two square feet is permitted. Each zone chapter (e.g., Section 17.16.010 for R-R) lists 'home occupations' as a use permitted outright, not conditionally.
Violations & Fines
Zoning code enforcement investigates complaints and can issue a notice of violation; operating outside these limits (employees on site, accessory-building storage, exterior signage or structural changes) removes the by-right protection and exposes the use to abatement as an unpermitted commercial use in a residential zone.
