How many sets of plans do I need a) at the time of filing for plan check and b) at permit issuance?
See Plan Submittal Requirements for the number of sets of plans required at the time you file your permit application. When a permit is ready to be issued, two sets of plans will be required: one each for the job site and the Building Department. In addition, if a project is for a new building or addition to an existing building, a third set of plans containing a site plan and all floor plans will be required for the county assessor’s office.
