Clay County, FL Building Safety: Plumbing Permits (2026)

Section 6-40(a)(3) adopts the latest edition of the Standard Plumbing Code as one of eleven technical codes every county permit must comply with, then layers on three specific local amendments: type M copper piping for use under pressure is prohibited under any building slab, a backflow preventing valve must be installed between the sewer tap and the required cleanout, and the sewer line cleanout must be located by means of some permanent, visible, above-grade marker. Like every other permit, a plumbing permit is filed with the building department under § 6-36 and reviewed within 30 days under § 6-41, and the application under § 6-37(a) must show the plumbing layout on the submitted drawings.

Only a contractor or master craftsman holding an active certificate under Chapter 7 may normally apply for or perform the work, per § 6-38(b), with narrow owner-builder exceptions for agricultural structures and commercial jobs under $25,000 in a twelve-month period, per § 6-38(c). The board of county commissioners can amend or delete any of the adopted technical codes, including the Standard Plumbing Code, under § 6-40(b), and the building official keeps at least three copies on file for public review under § 6-40(c). A permit that has been issued expires in 90 days under § 6-43 unless extended for just cause, and the fee schedule for plumbing permits is set and amended by board resolution under § 6-42(a).
