Water heater replacement permits in Long Beach, CA

General California guidance last updated May 22, 2026 · Long Beach data verified August 10, 2026

What plumbing contractors need to know about pulling a water heater replacement permit in Long Beach (Los Angeles County).

Short answer

In California, replacing a water heater almost always requires a plumbing permit (and often a mechanical or electrical permit too) because the work involves gas or electrical connections, venting, seismic strapping, and a T&P/expansion device. It is governed by the California Plumbing Code (Title 24, Part 5) and the California Mechanical Code (Title 24, Part 4), and is generally pulled by a licensed C-36 contractor.

Long Beach accepts submittal through the LB Services — Permitting and Licensing and has adopted the 2025 California Building Standards Code (with the Long Beach Municipal Code). Fee details and sources are below.

The general picture in California

A water heater changeout is treated as permitted plumbing work in nearly every California jurisdiction — even like-for-like. The reason it is rarely treated as maintenance: it modifies gas piping or electrical, requires combustion-air and venting verification, and California requires seismic strapping at two points, a temperature & pressure (T&P) relief discharge to an approved location, and a thermal-expansion device on closed systems. Tankless and heat-pump conversions add load calculations and circuit/venting work. Fees, submittal format, and inspection scheduling are set per city — confirm with the local building department.

Common reasons water heater replacement applications get bounced

Code-rooted patterns across California — not a Long Beach-specific rejection rate.

The inspection sequence

A typical order — the number of stops and exact sequence vary by jurisdiction and scope.

  1. 1Underground/rough not typically required for an in-place replacement
  2. 2Gas pressure test for new or modified gas piping
  3. 3Final inspection with the unit installed, strapped, vented, T&P routed, and tested

Licensing — who can pull it

Water heater work in California is generally performed by a C-36 (Plumbing) licensed contractor — or a C-20 (HVAC) when the unit is classified as a warm-air-furnace/water-heater combo, or a C-10 (Electrical) for the electrical-only portion of a heat-pump install. A B (General Building) contractor may pull within a larger project under CSLB rules. The contractor doing the work typically pulls the permit.

Frequently asked questions

Do I need a permit to replace a like-for-like water heater in California?

Generally yes, even like-for-like. Almost every California city treats a water-heater changeout as permitted plumbing (and often mechanical) work because of the gas/electrical, venting, seismic strapping, T&P, and expansion-tank requirements. The fee and process are set by the city — confirm with the local building department.

Is a separate permit needed for a tankless or heat-pump conversion?

Usually yes — converting to a tankless gas heater typically requires gas-line upsizing (and may add electrical for the venting fan or controls); a heat-pump water heater adds an electrical permit (dedicated circuit, often a load calc) plus venting/condensate work. Conversions are not like-for-like changeouts.

What does California require for the T&P discharge?

The California Plumbing Code requires the temperature & pressure relief valve to discharge through a full-sized line to an approved location — typically outside at grade, never into a fixture or interior space. Inspectors check the termination and pipe sizing on every install.

Can a homeowner pull the permit?

California allows homeowners to perform certain work on their own primary residence under CSLB rules, but the permit and inspection requirements still apply. getPermit is built for licensed contractors — for owner-pulled permits, contact the city directly.
