Overview & Permits

This hub explains where the CPC sets out permit rules, inspections, fees, and enforcement (notably §§101–106, including §104 Permits and §105 Inspections).

Last reviewed: July 6, 2026

Overview

This part of the California Plumbing Code (CPC) covers the code’s administration, permit requirements, inspections, fees, enforcement, and related authorities. It explains when a written construction permit is required for plumbing work, what work may be exempt, how permits are applied for and issued, and the enforcement powers available to the Authority Having Jurisdiction (§101.0–§106.0, with a focus on §104.0 Permits and §105.0 Inspections).

Why it matters: permits and administration are the gateway to legal, safe plumbing work—permits protect public health and ensure installations meet minimum standards, provide required plan review and inspections, and establish fee and penalty processes that local agencies use to enforce compliance (§1.8.4; §104.1–§104.5).

Key procedural provisions include the duties and powers of the enforcing authority (see §103.0), the detailed permit sections (§104.1 Permits Required; §104.2 Exempt Work; §104.3 Application for Permit; §104.4 Permit Issuance; §104.5 Fees), and inspection/testing and enforcement chapters (§105.0 and §106.0). For topic-specific permit rules (for example, recycled/reclaimed water systems) the code also contains targeted permit and plan-submission requirements (see §1505.2 and §1505.2.1).
