A minimum of one complete set of plans are required to obtain permits for most residential projects. Two or more sets are needed for Commercial projects or projects which require other permits. In general, however, a complete set includes (but is not necessarily limited to):
Site Plan - showing the position of the proposed project in relation to existing buildings, property lines, right of ways, and any easements.
Foundation Plan - indicating the type, size and location of new foundations or footings.
Floor Plan - detailing the location of walls, supports, size and location of doors, windows, electrical outlets, heaters, plumbing fixtures, smoke detectors, and the square footage of the project. Again, as with the plot plan, what is existing and what is proposed to be built should be clearly noted.
Roof Framing - Clearly indicating the size and methods of assembly of roof rafters and ceiling joists, or truss layout. Typically, roof slope and roofing materials are called out on this plan.
Floor Framing - Clearly indicating the size and methods of assembly of all floor framing members. Floor joists, girders and sub floor size along with foundation connections should be shown on this plan.
Cross Sections - Clearly indicating ceiling heights, wall construction, and R-value of any insulation to be used.
Exterior Elevations - Clearly showing how the exterior of the building will look upon completion. Doors, windows, exterior material, etc. should be shown.
Energy Calculations - Any time conditioned (heated or cooled) space is added to a building you are required to show compliance with the 2006 International Energy Conservation Code by submitting energy calculations.
Structural Calculations - Structural calculations may be required if your project is of large size, unusual shape and/or more than two stories in height. These calculations allow the Building Division to verify that structural elements are adequately sized and connected. A lateral analysis is generally required on large projects to determine the capacity of the building to resist lateral motion caused by earthquakes or wind. This portion of the project must be prepared by a licensed engineer.
Statement of special inspections is needed for commercial plans.
