Preparing your plan

Site Plan

A site plan is a drawing that depicts the placement of the project on the property. Site plans must be drawn to scale. Two versions are required unless a single site plan can clearly convey existing and proposed conditions: one that shows the existing site, and one which shows the site with proposed work.

It should show all buildings, including sheds, and the setbacks of a proposed project to the property line. It should also include the direction of drainage, landscaping, sidewalks, and other site features. It should show property dimensions, the location of adjoining streets and alleys, and location of all existing and proposed structures on the property with distances from other buildings and property lines specified. 

Floor Plan(s)

Floor plans show building dimensions, room size, layouts, and uses, placement of walls, location, operation type, and size of windows, doors, stairs, plumbing fixtures, electrical outlets and light fixtures (residential projects only), fireplaces, and cabinets.

Exterior Elevations

Exterior elevations show all sides of the building being constructed or remodeled. Exterior elevations also indicate the height of the structure and specify the exterior materials being used.

Structural Plans

Structural plans include foundation, floor framing, roof framing, cross sections, and drawings of specific aspects of the project, such as details for foundation, framing and fire resistive construction.  A good example is a footing detail. The detail drawing would show the size and materials required for the construction of the footing, and a reference on the foundation plan to where the footing detail is located in the plan set.  Structural plans must be signed and stamped by the Engineer of Record.

Structural Engineering Calculations

Stamped and signed structural engineering calculations are only needed if your project does not meet conventional code requirements per the California Building Code.

Energy Compliance Documentation

Energy compliance documentation is needed if the area of conditioned space is being increased as necessary to comply with the California Building Code. 

Truss Calculations

Signed and stamped truss calculations are required if utilizing roof or floor trusses for the project. The calculations must match the roof and floor plan provided in the plan set. When truss shop drawings are allowed to be deferred the building Engineer of Record must provide a shop stamp or conformance letter with the truss calculations.

Product "Listing" Numbers

Specify the product listing numbers of the materials to be used, (i.e., roofing, skylights, spas, fireplaces, and fireplace inserts). The numbers are to be provided by an approved testing agency, such as Underwriters Laboratories, International Code Council, or International Association of Plumbing and Mechanical Officials.

Automatic Fire Extinguishing System Plans

Automatic Fire Extinguishing System Plans include drawings, calculations, and specifications. These are required for remodels and tenant improvements where the walls or ceilings are being added, remove, relocated, or modified.

Deferred Submittals

Deferred submittals are used for work that will be submitted after the main permit is issued. Deferred submittals are not allowed for residential projects. Stairs and trusses on new commercial projects may be deferred without approval from the Plan Review Supervisor; all other deferred submittals must be approved by the Plan Review Supervisor. The cover sheet of the main permit must clearly state the exact scope of work authorized to be deferred. A deferred submittal cannot be used to review and authorize work which was not specified as deferred work on the main permit.
