Summary

Ouachita Parish adopts the Louisiana State Plumbing Code, Part XIV of the State Sanitary Code, as the regulation governing plumbing work in the unincorporated parish, and § 3½-107 makes it unlawful to install, alter, repair, or replace a plumbing system without a permit from the parish building official.

These county ordinances apply to unincorporated areas of Ouachita Parish. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Pursuant to R.S. 40:1730.21 et seq., the following codes are hereby adopted as the regulations governing the construction of buildings and other structures in the unincorporated areas of Ouachita Parish, Louisiana...(e)Louisiana State Plumbing Code (Part XIV (Plumbing) of the State Sanitary Code); and... It shall be unlawful to construct, enlarge, alter, repair, move, demolish, or change the occupancy of any building or structure, or to erect, install, enlarge, alter, repair, remove, convert or replace any electrical, gas, mechanical or plumbing system, the installation of which is regulated by the technical codes adopted in section 3½-104...without obtaining a properly issued permit from the parish building official and that official has approved the application for permit.

Full Breakdown

' The permit application under § 3½-107 must describe the work, including whether it involves plumbing, and certify compliance under penalty of perjury. Section 3½-123(b)(4)(i)-(j) exempts routine plumbing maintenance from a permit, including 'the stopping of leaks in drains, water, soil, waste or vent pipe' and 'the clearing of stoppages or the repairing of leaks in pipes, valves or fixtures,' so long as the work does not require replacing or rearranging pipes or fixtures; replacing a defective concealed pipe, however, is treated as new work requiring a permit and inspection. The building official inspects the work and must issue a certificate of completion and compliance under § 3½-108 before the system may be used.

Violations & Fines

Installing or altering plumbing that requires a permit without one is a misdemeanor under § 3½-111, punishable by a fine of not less than one hundred dollars and not more than five hundred dollars for each offense, and the building official may seek to enjoin the unpermitted work or its use under § 3½-109.
