You need to schedule a submittal appointment in order to apply for a commercial mechanical plan review permit. Effective immediately, you may submit only one application per appointment. We recently reduced the length of each appointment and added additional appointments each week. Please call (206) 684-8850 to schedule a paper intake appointment. You can schedule your e-plan appointment using the DPD Project Portal.  Remember to provide detailed plans, a completed cover sheet, and any additional information required so that we can review and approve your plans. This will help DPD intake staff and plan reviewers quickly and easily complete your intake.  Additional information is available in Tip 415, Applicant Responsibilities and Plan Requirements for Mechanical Permits.
