Chico's Building Safety: The Rules That Matter

Every city handles building safety a little differently. In Chico, California, there are 7 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Plumbing Permits

Chico requires a plumbing permit before installing, removing, altering, repairing, or replacing plumbing equipment in any building, structure, or premises, with narrow exemptions for minor leak repairs and clog-clearing that don't involve replacing pipes or fixtures.

Key details: Permit trigger: install, alter, repair, replace plumbing. Adopted code: 2025 California Plumbing Code. Issuing office: Chico Building Division. Minor-repair exemption: leak stops, stoppage clearing only. Violation penalty: infraction, fine up to $1,000.

Unpermitted plumbing work violates the permit requirement of § 16.10.030.C; under City Charter § 1505 a code violation is an infraction punishable by a fine up to $1,000 unless the ordinance specifies otherwise.

Childcare Center Rules

Chico requires large family day care homes to have a fire extinguisher and smoke detectors and pass a City inspection for Housing Code and Fire Marshal compliance.

Key details: Required equipment: Fire extinguisher, smoke detectors. City inspection: Housing Code compliance. Home spacing: 300 feet apart. State license: CA Dept. of Social Services.

Operating a large family day care home without the City's non-discretionary permit or the required State Department of Social Services license is a code violation subject to permit denial or revocation.

Electrical Permits

Chico requires a separate electrical permit for installing, altering, repairing, replacing, or remodeling any electrical equipment in a building, with narrow exemptions for portable equipment and minor repairs.

Key details: Permit required for: install, alter, repair, replace, remodel. Exempt: portable equipment, lamps, fuses. Adopted electrical code: CMC Chapter 16R.04. Authority: CMC § 16.10.030(A).

Performing electrical work without the required permit is a code violation; the City can issue a stop-work order, require an inspection and after-the-fact permit, and cite the work as an infraction under the general penalty provision, § 1.04.120.

Building Inspections

Chico requires five building-official inspections during construction: foundation, slab/underfloor, frame, lath/wallboard, and final, before work may proceed past each stage.

Key details: Governing section: CMC § 16.14.020. Inspection stages: 5: foundation, slab, frame, lath, final. Request notice: 24 hours before inspection, § 16.14.070. Steel/framing rule: Inspected before covered or concealed.

Covering or concealing work before the required stage inspection is approved violates § 16.14.010; the building official may order the work exposed for inspection, and further construction is barred until it passes.

Green Building Code

Chico, California enforces the 2025 California Green Building Code (CALGreen) as its local green building standard, adopted by reference under Chico Municipal Code § 16R.16.010 for all new construction, alteration, and repair work citywide.

Key details: Code adopted: 2025 California Green Building Code, Part 11. Applies to: construction, alteration, repair of structures. Local citation: Chico Municipal Code § 16R.16.010. Penalty: infraction; up to $1,000/6 months if ignored.

Violating an adopted building regulation, including the Green Building Code, is an infraction fined under City Charter § 1505; ignoring a stop-work or permit-revocation order is a misdemeanor punishable by up to $1,000 and six months in county jail (Chico Municipal Code § 16.16.090).

Fire Sprinkler Requirements

Chico's Traditional Neighborhood Development standards require fire sprinklers in any building on an off-network street more than 150 feet from the neighborhood's Emergency Response Network.

Key details: Trigger distance: Over 150 feet from ERN street. Applies to: Buildings in TND zoning district. Alleys: Counted as off-network streets. State baseline: CRC § 313.2 covers new 1-2 family homes.

Constructing a qualifying TND building without the required sprinkler system can result in permit denial, a stop-work order, or code enforcement action under the city's building and fire standards.

Building Permits

Chico requires a basic building permit for any alteration, repair, improvement, or remodel of a building or structure, with only a short list of minor exemptions under the Municipal Code.

Key details: Permit required for: alteration, repair, remodel, enlargement. Issued by: Building Division. Interior remodel exemption: zoning-only, not building permit. Authority: CMC § 16.10.020.

Remodeling or altering a structure without a permit is a code violation; the City can issue a stop-work order and cite the work as an infraction (up to $1,000) or misdemeanor under the general penalty provision, § 1.04.120, plus require after-the-fact permitting, inspection, and fees.
