Home Business in Chico, CA: What Residents Actually Need to Know

If you live in Chico or are thinking about moving there, home business are one of those things you probably won't think about until they affect you directly. Chico has 5 specific rules on the books covering different aspects of home business, and some of them might surprise you.

Customer Traffic Restrictions

Per CMC 19.20.060, a Chico home occupation may not generate more than 10 additional pedestrian or vehicular trips per day beyond what is customary for the residential zoning district. Customers and clients are prohibited on the premises between 10:00 p.m. and 8:00 a.m. All home-occupation parking must occur on-site or in legal on-street spaces without obstructing neighbor access.

Key details: Max additional trips/day: 10 above baseline for the zone. Customer/client hours: 8:00 a.m. – 10:00 p.m.. Code section: CMC §19.20.060. Heavy commercial deliveries: Restricted.

Generating excessive traffic or hosting customers outside permitted hours is a violation of CMC 19.20.060 and the Home Occupation Permit. Neighbors may complain to Code Enforcement, which can revoke the permit, issue administrative citations, and require business cessation at the residence.

Zoning Restrictions

Chico Municipal Code Chapter 19.20 allows home occupations in any residential zoning district with an approved Home Occupation Permit issued by the Community Development Director. The use must be clearly incidental and secondary to the dwelling's residential character, conducted entirely within the principal residence of the applicant, and may not exceed 50 percent of net floor area or 400 square feet, whichever is less. CMC 19.20.060 caps employment at residents plus one additional employee.

Key details: Code section: CMC Ch. 19.20 / §19.20.060. Floor area cap: 50% of net floor area or 400 sq ft (lesser). Max non-resident employees: 1. Permit issuer: Community Development Director. Business license: Required (CMC Title 5).

Operating a home business without a Home Occupation Permit, or violating standards in CMC 19.20.060, is a zoning code violation enforceable by Community Development Code Enforcement and may result in permit revocation, administrative citation, and abatement orders.

Home Daycare

California Health & Safety Code §1597.40 preempts local zoning of family daycare homes. Small family daycare homes (up to 8 children) are treated as residential use in every zone allowing single-family homes. Large family daycare homes (up to 14 children) cannot be prohibited on lots zoned for single-family dwellings. Chico cannot require a Home Occupation Permit, conditional use permit, or business license that would directly or indirectly restrict a licensed family daycare home. Licensing is handled by California Department of Social Services Community Care Licensing (CCLD).

Key details: State preemption: Cal. HSC §1597.40. Small family daycare cap: 8 children (HSC §1596.78). Large family daycare cap: 14 children (HSC §1597.465). Licensing agency: CA DSS Community Care Licensing. Local CUP required: No — by-right in SF zones.

If Chico were to enforce a local restriction prohibiting or unduly burdening a licensed family daycare home, the operator could invoke HSC §1597.40 preemption. Operating an unlicensed daycare beyond statutory exemptions (e.g., caring for unrelated children for compensation without a CCLD license) violates HSC §1596.80.

Chico is more permissive than most cities when it comes to home daycare. That said, there are still limits.

Signage Rules

CMC 19.20.060 limits home occupation signage to one non-illuminated name plate not exceeding 1 square foot in area, with placement approved by the Community Development Director. No display of merchandise, stock-in-trade, or other identification of the home occupation is allowed on the premises. Citywide sign rules in CMC Ch. 19.74 also apply.

Key details: Number of signs: 1. Maximum size: 1 sq ft. Illumination: Prohibited. Approval: Community Development Director. Merchandise display: Prohibited.

Unpermitted or oversized signage at a home occupation triggers code enforcement action under CMC 19.74 and may jeopardize the Home Occupation Permit. Typical resolution is sign removal plus an administrative citation.

Compared to other cities, Chico takes a harder line on signage rules. The enforcement and penalty structure reflects that.

Cottage Food Operations

California's Homemade Food Act (Health & Safety Code §113758 et seq.) governs Cottage Food Operations (CFOs). Class A CFOs (direct sales) self-certify with Butte County Environmental Health; Class B CFOs (indirect sales through retailers) require a county-issued permit and annual kitchen inspection. State law sets the gross-sales caps ($75,000 Class A, $150,000 Class B). Chico does not impose a separate ban — CFOs that meet state law are an allowed home occupation use under CMC 19.20.060.

Key details: State authority: Cal. HSC §113758 et seq.. Class A cap: $75,000 gross/year (direct sales). Class B cap: $150,000 gross/year (direct + indirect). Registrar: Butte County Environmental Health. Contact: BCEnvHealth@ButteCounty.net.

Operating a CFO without county registration/permit is a violation of HSC §114405 and may trigger cease-and-desist orders, fines, and embargo of products. City code enforcement can separately cite for missing business license or violation of home occupation standards.

The Bottom Line

Chico's home business rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Chico is broadly strict or permissive.

These rules come from Chico's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
