When are building plans required?
Plans are required for any addition, alteration or construction of a new structure (Structural and Non-Structural). Some projects that require plan submittals are:
- Removing all or part of a wall
- Skylight
- Changing garage parking or storage areas to a recreation room, play room, or bedroom
- Any addition to the building or property such as adding a deck in the rear yard, constructing a new addition, or adding a new story. Also, building a new deck or enlarging an existing one, when the deck surface is more then 18 inches above the ground. (Check with the zoning codes to see if restrictions apply)
- Changing the number of dwelling units
- For a building permit application that requires plans:
- Submit a minimum of four sets
- Draw to a uniform scale (1/8" = 1 ft. or 1/4" = 1 ft).
- Paper size no less than (11" x 17")
- Draw in a manner so that they can be microfilmed
- Plans must show location, nature and extent of the existing and proposed work.
- Show, in detail, how they conform to the provisions of the code and all other laws and regulations.
- If submitting structural plans, two sets must be submitted, wet stamped and signed by a professional engineer or architect.

A complete plan should illustrate the following items:
- Building location and relationship to the street, sidewalk, property lines and other items on or near the property.
- Distance(s) between the house walls and the front, back, and side lot lines.
- Exterior elevations illustrating the addition or the change being made.
- Plans for each floor being remodeled or added to show both the existing and proposed work.
- Type and size of all building materials to be used. Show connections/attachments.
- Structural drawings and calculations if required.

Information and forms that have been glued, pasted or taped onto plans are not acceptable, nor is "white-out" allowed on permit drawings.
