OAR 918-780-0040: Plumbing Plan Reviews

(1) The division or a jurisdiction providing plumbing code plan review services, including plan review for prefabricated structures, may only require plumbing plan review for a complex structure. For purposes of this rule, a “complex structure” is a plumbing system designed, constructed or reconstructed to accommodate any of the following: (a) The installation or alteration of a medical gas and vacuum system for health care facilities; (b) The installation or alteration of chemical drainage waste and vent systems containing chemical agents potentially detrimental to the integrity of a plumbing system; (c) The installation or alteration of wastewater pretreatment systems for building sewers; (d) The installation of vacuum drainage waste and vent systems; (e) The installation or alteration of reclaimed wastewater systems; (f) The installation of a commercial booster pump system needed to maintain a minimum residual water pressure in a structure supplied by a municipal source; (g) The installation of a plumbing system requiring a building water service line with an interior diameter or nominal pipe size of two inches or greater except those two-inch systems which have been designed and stamped by a licensed engineer; (h) The installation of any multipurpose sprinkler system under standards adopted by the department. (i) Prefabricated buildings as defined in ORS 455.010 and as further defined by the division in OAR chapter 918, division 674, where the division performs plan review for the construction or alteration of prefabricated buildings. (2) If the division or a jurisdiction providing plumbing code plan review services requires a plumbing code plan review as authorized by section (1) of this rule, the division or jurisdiction may require the submission of complete specifications, piping layout and fixture location drawings of the proposed system or alteration before issuing a permit. Plans and specifications must indicate the nature and extent of the work proposed and show in detail that the work will conform to provisions of the Oregon Plumbing Specialty Code. (3) The division or the jurisdiction requiring plumbing code plan review may not require plan review on more than one building or structure under construction or reconstruction at the same jobsite, as long as: (a) The plumbing systems of the buildings or structures are materially alike; and (b) A person obtains plumbing permits for the buildings or structures within a reasonable time. (4) Any required plumbing code plan review service may be waived by the division or jurisdiction if the nature of the work applied for is such that reviewing of plans is not necessary to determine compliance with the Oregon Plumbing Specialty Code. (5) When the plumbing plan review is completed by a qualified plumbing plan reviewer and a plumbing permit issued, the plans must be endorsed in writing and stamped “Approved.” The approved plans cannot be changed without authorization from the division or jurisdiction providing plumbing code plan review services. (6) Issuance of a permit or approval of plans will not prevent the division or jurisdiction providing plumbing code plan review services from (a) requiring the correction of errors in plans and specifications; or (b) Preventing construction operations when in violation of the Oregon Plumbing Specialty Code or of any other ordinance; or (c) Revoking any certificate of approval when issued in error. (7) Nothing in this rule prevents a jurisdiction from providing plan review services for utility systems situated outside the building exterior of a particular jobsite. (8) Nothing in this rule prevents a jurisdiction from requiring information on grease processing equipment systems. (9) Where applicable, the Department of Consumer and Business Services’ fees for plan review on complex structures will be based on the time required to review the plans, but must not exceed 30 percent of the total plumbing permit fee for the building or structure under review. When plans are incomplete or substantially changed to require additional plan review services, the department may charge an additional fee based on the time required for the additional review. (10) Nothing in these rules shall prohibit the owner or owner’s agent from requesting and receiving a plan review for non-complex structures.
