Plumbing permit applications for properties in unincorporated areas of Los Angeles County are submitted to the Los Angeles County Public Works Building and Safety Division. You can apply in person at their office or conveniently through the online EPIC-LA portal. The process involves completing an application form, paying applicable fees, and potentially submitting plans and specifications for review, especially for more complex projects. A plan check, which is a review of project plans for compliance with building codes, may be required before a permit can be issued.

California Plumbing Legislation, Codes, and Guidelines
California Plumbing Code and Legislation
In California, plumbing standards are governed by the California Plumbing Code (CPC), which is Part 5 of Title 24 of the California Code of Regulations. Unlike many other states that adopt the International Plumbing Code (IPC), California bases its plumbing code on the Uniform Plumbing Code (UPC). The state integrates the UPC with specific California amendments to address unique regional requirements, such as seismic safety, water conservation, and drought management.
The California Building Standards Code is updated on a triennial cycle. As of April 2026, the 2025 California Plumbing Code is the current enforceable standard, having taken effect on January 1, 2026. These regulations apply to all new construction, major renovations, and plumbing system installations across residential, commercial, and industrial properties throughout the state.
Primary State Agencies
The regulatory framework for plumbing in California involves several key entities:
- California Building Standards Commission (CBSC): The primary agency responsible for the formal rulemaking process, adoption, and publication of the California Building Standards Code (Title 24).
- Department of Housing and Community Development (HCD): Holds authority over building standards specifically related to residential housing.
- Contractors State License Board (CSLB): The agency responsible for licensing plumbing contractors (e.g., C-36 classification) to ensure that work is performed by qualified professionals.
- Local Building Departments: While the state sets the minimum standards, local city and county jurisdictions are responsible for enforcement, permitting, and inspection. These local authorities may also adopt stricter local amendments to the state code.
