Drawings show the Inspector exactly what you want to do and allows the Inspector to review the drawings to make sure the applicable codes are being met and the construction, when finished, will be safe for human occupancy for years to come. Two types of drawings are required to be submitted for permit approval. A site plan must be submitted that shows the size and shape of the lot, all existing and proposed structures on the lot, and correct dimensions of the structures and their distances from property lines. It is recommended that the site plan be drawn to scale. These plans must be drawn to scale and should include foundation and framing details, building elevations, floor plans, electrical, plumbing and heating details.
New homes require more detail on drawings than room additions, garages and sheds.
The Plans Examiner should be able to understand completely what you intend to do by reviewing your drawings. Drawings submitted that are not complete, legible or require more information, may be rejected and returned for redesign and clarification. The other set should be kept by the owner or contractor for their records. Photographs of an existing structure to which an addition or modification is proposed are helpful, but not required. When submitting drawings for permit approval, you will be asked to complete an application for a building permit.
