Watsonville, CA Building Safety: Plumbing Permits (2026)

Section 8-7.01 of the Watsonville Municipal Code adopts the California Plumbing Code, Part 5, 2025 Edition, as the plumbing code for the City of Watsonville, through Ord. 1483-25 effective January 1, 2026. The adopting language covers the design, construction, quality of materials, erection, installation, alteration, repair, location, relocation, issuance of permit and collection of fees for plumbing, and it allows additions, insertions, deletions, modifications and changes set forth in the chapter.

The local change is in § 8-7.02, which lists three sections not adopted: Section 104.3.2 (Plan Review Fees), Section 104.5 (Fees) and Table 104.5 (Plumbing Permit Fees). The City of Watsonville drops the model code fee provisions and prices plumbing permits another way. Section 8-1.04(b) requires a fee for each permit on plumbing systems or alterations requiring a permit in accordance with the schedule of fees established by resolution of the City Council. The mechanical code chapter makes the same cut: § 8-6.02 does not adopt Section 104.5 or Table 104.5 there.

The administrative rules apply to plumbing work as they do to every trade. A permit is not valid until the fees are paid (§ 8-1.04(a)). The applicant states a permit valuation covering total work, materials and labor, including permanent systems, and the Building Official sets the final valuation (§ 8-1.04(c)). Refunds run up to eighty (80%) percent of the permit fee when no work has been done, on a written application within one hundred eighty (180) days of payment (§ 8-1.06). The Building Official enforces the title under § 8-1.03, and the appeals board under § 8-1.07 reserves a seat for a registered design professional with mechanical and plumbing engineering experience or a mechanical or plumbing contractor with at least ten (10) years of experience.
