This page is for Californians running a business from home, from a spare-room office to a home bakery or family daycare. California has no general statewide home-occupation law, so cities set the rules on employees, signs, customer visits and parking. State law does protect a few home businesses. A licensed small or large family daycare home is a residential use by right under Health & Safety Code §1597.45, and a city can't require a use permit or charge a business license fee for one. Under Gov. Code §51035 (AB 1616, effective 2013), cities can't prohibit cottage food operations, though you must register or get a permit from the county environmental health agency. Home kitchens selling meals are allowed only where the city or county has authorized them.

Six of the 9 cities we cover for this topic require a home occupation or home business permit: Hillsborough, Los Gatos, Manhattan Beach, Pasadena, Piedmont and Tiburon. Del Mar, Los Altos and Saratoga allow low-impact home occupations without one. Nearly all limit employees to residents; Tiburon allows one nonresident employee. Customer visits are tightly limited: none in Piedmont or Del Mar, one at a time in Los Gatos, appointments only in Pasadena, and eight a day in Los Altos. Manhattan Beach and Pasadena cap the business at 500 sq ft. Los Altos's code still calls for a use permit for large family daycare, which state law may override. Pick your city below for the details and the municipal code text.

California state protections for home-based businesses

California has no general statewide home-occupation law. Cities and counties set the rules on employees, signs, customer visits and parking. State law protects a few specific home businesses:

Family child care homes (Health & Safety Code §1597.45):

  • A licensed small (up to 8 children) or large (7 to 14 children) family daycare home is a residential use by right under all local ordinances, including zoning. A city can't require a use permit.
  • Cities can't charge a business license, fee or tax for operating one, and it isn't a change of occupancy under building codes.
  • Local rules may apply only if they are identical to those for other homes in the same zone, whether the home is rented or owned.

Cottage food operations (Gov. Code §51035; AB 1616, effective 2013):

  • Cities and counties can't prohibit home cottage food operations. They must allow them as a permitted use or through a permit limited to reasonable spacing, traffic, parking and noise standards.
  • A cottage food operation has no more than one full-time-equivalent employee besides family or household members. Class A (direct sales only) is capped at $75,000 a year and Class B at $150,000, adjusted for inflation (H&S Code §113758).
  • You must register (Class A) or get a permit (Class B) from the county environmental health agency.

Home kitchens selling meals (microenterprise home kitchen operations): allowed only where the city or county has authorized them, with a permit and a limit of 30 meals a day and 90 a week (§113825).

Common questions about home businesses in California

Do I need a home occupation permit in California?
It depends on your city. There's no statewide home-occupation permit. Among the cities we cover, Hillsborough, Los Gatos, Manhattan Beach, Pasadena, Piedmont and Tiburon require one, while Los Altos, Saratoga and Del Mar allow low-impact home occupations without a separate permit if you follow their rules. Many cities also require a business license.
What is a home occupation?
A home occupation is a business run inside your home as a secondary use of the residence. City codes typically limit employees to residents and restrict signs, customer visits, storage and anything visible from outside so the home still looks and functions like a home. The exact limits vary by city.
Can I have employees for a home business in California?
It depends on your city, but usually only residents. Most cities we cover allow no nonresident employees working on site; Tiburon allows one, with an extra parking space. Cottage food operations may have one full-time-equivalent employee besides family or household members under state law.
Can I run a daycare from my home in California?
Yes, if it's licensed. A licensed small (up to 8 children) or large (7 to 14 children) family daycare home is a residential use by right statewide. A city can't require a use permit or charge a business license fee for it, and local rules may apply only if they're identical to those for other homes in the zone.
Can I sell food I make at home in California?
Yes, for cottage foods. Cities can't prohibit cottage food operations, but you must register (Class A) or get a permit (Class B) from the county environmental health agency, and annual sales caps apply. Selling home-cooked meals is allowed only where your city or county has authorized microenterprise home kitchens, with a permit and a limit of 30 meals a day and 90 a week.
