A good resource for a plot plan is a survey issued for a recent mortgage or refinance closing. If you draw the plot plan yourself, be sure to sign and date it, and include contact information. The following are requirements to be shown on the Plot Plan.

• The plot plan should be drawn to scale, using an acceptable engineering scale. Include bar scale, north arrow, date map prepared including revision dates.
• Name and contact information of preparer of the map.
• Property lines with dimensions and road frontage shown.
• Dimensions, location and use of all existing and proposed buildings and structures including additions; distances between buildings measured at the closest point; and distance from buildings to closest property lines.
• Existing and proposed driveways, patios, pool decking, walkways, etc.
• All water features including drainage easements, streams, buffers, and flood zone. Watershed boundaries and WCA Tier lines labeled, including allowable and proposed impervious surfaces, total built-upon area shown in acres and with percent of total area noted.
• Any other easements or restrictions must be shown.

All Construction Plans submitted for permitting must match Plot Plan layouts exactly and are required to be designed to meet the provisions of the NC Residential Code. All structural information must comply with the provisions of the NC Residential Code. Structural elements not found in the NC Residential Code must be designed and plans bear the seal of a NC registered design professional.

This is a minimum plan review checklist; additional information may be added by the applicant or requested in the field by the Inspector to determine compliance. Permit holders remain responsible for meeting all code requirements regardless of whether a review item is listed. This minimum review checklist is intended to help prevent any major non-compliance issues from being built in the field, which typically results in significant costs and delays on a project.
