If a building permit is required for a complex rehabilitation project involving multiple codes, at the request of the prospective permit applicant, after payment of a fee, if required, and before the submission of the construction permit application, the authority having jurisdiction, or the authority's designee, and individuals who are agency representatives in accordance with §B of this regulation, shall meet with the prospective applicant to discuss plans for any proposed work or change of occupancy under this chapter before the application for the permit is submitted. The preliminary meeting, to the extent possible, shall include the officials responsible for permit approval and enforcement in the following areas, as may be applicable to the rehabilitation project: Building code; Mechanical code; Plumbing code; Electrical code; Fire code; Boiler code; Energy code; Elevator code; and Local historic preservation ordinances. When possible, a single meeting of all the parties shall be arranged. The purpose of the preliminary meeting is for the prospective applicant to present its intentions for the proposed work to the responsible code officials so that together they can determine which specific requirements of this chapter and the codes listed in §B of this regulation are to be applied to the proposed project. Decisions made at the preliminary meeting regarding the specific requirements of this chapter and the codes listed in §B of this regulation that are to be applied to the proposed project are binding on the prospective applicant and the code officials, their respective agencies, and local jurisdictions unless circumstances arise that were unknown or could not be ascertained by the prospective applicant at the time of the preliminary meeting. For a rehabilitation project or portion of a project that is in the repair, renovation, or modification category of work, a preliminary meeting may be granted at the discretion of the authority having jurisdiction when a request for a preliminary meeting is made by the prospective applicant before the submission of the construction permit application.
