Santa Monica Zoning Restrictions Rules (2026): What You Need to Know

SMMC Section 9.31 establishes the regulatory framework for home occupations in Santa Monica's residential zones. A home occupation is any business conducted within a dwelling unit that is clearly subordinate and incidental to the residential use. The business must be conducted entirely within the approved floor area of the dwelling or a permitted accessory structure; no commercial activity may spill into the yard, driveway, or other exterior areas. There must be absolutely no exterior indication of commercial use — no business signs, no window displays, no commercial vehicles permanently associated with the business, and no alteration to the building's appearance.

The ordinance limits staffing to one non-resident employee on-site at any time. This provision ensures that the business does not generate significantly more traffic or activity than a normal residential household. The business must not generate noise, vibration, odors, electrical interference, or any other nuisance condition detectable outside the unit. Storage of materials, equipment, or inventory beyond what is typical for a residence is prohibited. Prohibited home occupation types include auto and vehicle repair, animal breeding, any activity requiring a hazardous materials permit, and operations requiring customers to be served in-person at significant volumes. All home occupations must obtain a City business license, and the license application is reviewed by the Planning Division to confirm that the proposed business type is compatible with home occupation standards before the license is issued.
