What is a certifed plot plan?

A certfied plot plan is an accurate boundary survey of a parcel of land and shows all the structures on it, required building setbacks (from local zoning), any easements or rights-of-way that would affect building on the parcel, and any proposed structures, additions, fences etc.Typically this plan will also include locations of septic systems, wells, driveways, etc.  A plot plan protects the property owner by providing legal proof that the proposed improvements are in compliance with the zoning requirements

Why do I need one?

CMR 780, the State Building Code, requires that a Building Inspector certify that there are no zoning violations in order to issue a building permit or a certificate of occupancy. In order to do that, he needs to be able to determine beyond the shadow of a doubt that no zoning violations will exist—and a certified plot plan is the best way to do this. The most common zoning violation is an encroachment into required setbacks, and if the proposed building project would create such encroachment, approval must be obtained from the Zoning Board of Appeals prior to application for the building permit. Without this check-point, there would be little sense in requiring setbacks, the purpose of which are to ensure adequate light, air, and space between buildings on adjacent parcels of land.

CMR 780 R107.2 : "The construction documents submitted with the application for permit shall be accompanied by a site plan showing the size and location of new construction and existing structures on the site and distances from lot lines. In the case of demolition, the site plan shall show construction to be demolished and the location and size of existing structures and construction that are to remain on the site or plot."

How do I get one?

If you do not already have one and one is required to obtain a permit you will need to hire a registered land surveyor.
