Also, the size of any addition and it's corresponding setbacks must be show on the plan. Most projects require a floor plan of the new work and in many cases, the floor plan should include the surrounding areas, as the addition or modification may impact those areas.

Most residential projects do not require sealed structural plans. It is up to the code official, based on State Law, to determine when engineered plans are required.

Exterior changes include windows and window treatments, doors, building trim and any building element that changes in kind, form or shape. Manufacture's cut sheets also must be submitted.
