Summary
Fremont adopts the 2025 California Plumbing Code as the Fremont Plumbing Code under Municipal Code Section 15.20.020, with only three CPC appendices in force and a local earthquake gas shutoff valve mandate. Permit administration and enforcement for plumbing work runs through the general building permit procedures in Chapter 15.05 and Section 15.10.040.
The 2025 Edition of the California Plumbing Code (CPC) as published by the California Building Standards Commission is adopted as the plumbing code of the city of Fremont, California, as if fully set out in this chapter, and is amended as set forth in this chapter. A copy of the 2025 CPC shall be maintained on file in the office of the building official. ... Section 1211.8 Earthquake-Actuated Gas Shutoff Valves. Earthquake-actuated gas shutoff valves designed to automatically shut off the gas at the location of the valve in the event of a seismic disturbance and certified by the State Architect as conforming to California Code of Regulations, Title 24, Part 12, Chapter 12-16-1, shall be installed in all new buildings and in existing buildings that undergo alterations or additions that exceed $10,000.

Full Breakdown
020 adopts the 2025 Edition of the California Plumbing Code as published by the California Building Standards Commission as the plumbing code of the city of Fremont, as if fully set out in the chapter, and directs that a copy be kept on file in the office of the building official. 030 limits which CPC appendices apply locally to Appendix A (Recommended Rules for Sizing the Water Supply System), Appendix B (Explanatory Notes on Combination Waste and Vent Systems), and Appendix D (Sizing Storm Water Drainage Systems); no other appendix is adopted.
040 of the Fremont building code for administration and enforcement, meaning a plumbing permit follows the same application, fee, expiration, and inspection rules that apply to a building permit. 050, requires an earthquake-actuated gas shutoff valve, certified by the State Architect under California Code of Regulations Title 24, Part 12, Chapter 12-16-1, on every new building and on any existing building undergoing alterations or additions exceeding $10,000 in value.
Violations & Fines
Because plumbing permits are administered under the general Fremont building code, plumbing work performed without a permit is subject to the same doubled permit fee under Section 109.4 and separate investigation fee under Section 109.4.1 that apply to unpermitted building work. Skipping the required earthquake-actuated gas shutoff valve on a qualifying new building or a remodel over $10,000 leaves the installation out of compliance with Section 15.20.050 and subject to correction before final inspection.
