Building Safety in Compton, CA

If you live in Compton or are thinking about moving there, building safety are one of those things you probably won't think about until they affect you directly. Compton has 6 specific rules on the books covering different aspects of building safety, and some of them might surprise you.

Plumbing Permits

Compton has adopted the 2019 California Plumbing Code in full to govern every plumbing installation, alteration and repair in the city. A permit from the Building and Safety Department is required before most plumbing work begins, though narrow repair exemptions apply, and permits expire if work stalls.

Key details: Code adopted: 2019 California Plumbing Code, in full. Permit expiration: 365 days if work not started. Suspension limit: 180 days before permit voids. Extension available: Up to 180 days, written request. Max misdemeanor fine: $1,000 and/or 6 months.

Working without a required plumbing permit, or violating any provision of the adopted Plumbing Code, is a misdemeanor under § 15-24 punishable by a fine up to $1,000, imprisonment up to six months, or both, unless the City deems the violation an infraction. Each day a violation continues is a separate offense, and the City may also pursue an administrative penalty or abate the condition as a nuisance through civil process under § 15-25.

Electrical Permits

Compton regulates all electrical wiring, fixtures, and appliance installations under the 2019 California Electrical Code, adopted by reference under Municipal Code § 15-8.1. Based on the 2017 National Electrical Code, it governs permits for new wiring, alterations, and repairs citywide, with the standard state text unmodified by local amendment.

Key details: Adopted code: 2019 California Electrical Code. NEC base: 2017 National Electrical Code. Adopting ordinance: Ord. No. 2339 (10-26-2021). Local amendments: None currently in force. Permit-exempt work: Lamp replacement, existing receptacles only.

Installing, altering, or repairing wiring, panels, or fixtures beyond the narrow repair-and-maintenance exemption in Section 105.2(b) without an electrical permit is unpermitted electrical work, enforceable under the adopted 2019 California Electrical Code and the City's general Building Code violation provisions in Chapter 15.

Fire Sprinkler Requirements

Compton ties fire sprinklers in an accessory dwelling unit directly to whatever the primary house needs. Section 30-11.2.j.2(h) of the zoning code requires an ADU, attached or detached, to include fire sprinklers only when the primary dwelling or a proposed multi-family structure on the same lot is itself required to have them.

Key details: Section: § 30-11.2.j.2(h). Trigger: Sprinklers required if primary dwelling requires them. Applies to: Attached and detached ADUs. Review type: Ministerial, no public hearing. Processing deadline: 60 days per Gov. Code § 65852.2.

An ADU application that omits required fire sprinklers cannot clear the Section 30-11.2.j development-standard review the Community Development Director performs before ministerial approval. Building and Safety will withhold plan check sign-off and the certificate of occupancy until sprinklers are installed to match the primary dwelling's requirement, effectively stalling occupancy of the unit rather than triggering a separate fine.

Childcare Center Rules

A Compton home caring for up to 14 children under Section 30-11.3.b must meet a specific set of building and site conditions: a 5,000 square foot minimum lot, a solid fence or wall around the rear yard, restored off-street parking, and a certificate of occupancy before operating.

Key details: Section: § 30-11.3.b. Capacity: Up to 14 children (large home). Minimum lot size: 5,000 square feet. Spacing rule: No other home within 300 feet. Outdoor hours: 9:00 a.m. to sunset, rear yard only.

A large family child care home operating without a certificate of occupancy under Section 30-33, without Architectural Review Board approval of its site and floor plans, or without the required rear-yard fencing and off-street parking is out of compliance with Section 30-11.3.b and subject to code enforcement action through the City's standard municipal code violation process.

Green Building Code

Compton enforces the 2019 California Green Building Standards Code (CALGreen) in full for construction citywide, covering water efficiency, material conservation and building commissioning on top of the standard building code.

Key details: Code adopted: 2019 California Green Building Standards Code. Local amendments: None filed; § 15-14.2 reserved. Enforcing agency: Compton Building and Safety Department. Max misdemeanor fine: $1,000 and/or 6 months.

Violating any provision of the adopted Green Building Standards Code is a misdemeanor under § 15-24, punishable by a fine up to $1,000, imprisonment up to six months, or both, with each day of a continuing violation charged as a separate offense; the City may alternatively pursue an administrative penalty or abate a violation as a nuisance under § 15-25.

Building Permits

Compton enforces the 2019 California Building Code and requires a permit for nearly all construction. Municipal Code § 15-4.2 lists the narrow categories of work exempt from a permit, from small tool sheds under 120 square feet to short retaining walls, meaning everything else needs Building and Safety Department review before work starts.

Key details: Adopted code: 2019 California Building Code. Permit-exempt shed size: Up to 120 sq ft, 12 ft tall. Permit-exempt fence height: 5 ft masonry / 6 ft wood. Permit expires: Not started within 365 days. Permit voids: Work stopped 180+ days.

Section 105.2 states plainly that an exemption from the permit requirement 'shall not be deemed to grant authorization for any work to be done in any manner in violation' of the Building Code or any other city law or ordinance. So work that falls outside the listed exemptions, or that violates zoning, setback, or safety standards even while permit-exempt, remains enforceable as an unpermitted or noncompliant construction violation.

The Bottom Line

Compton's building safety 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 Compton is broadly strict or permissive.
