Does the Planning Department have a copy of my plot plan?

Possibly. If an application was previously submitted to the Board of Zoning Appeals, then a certified plot plan should be on file. In addition, plans may be available from the Conservation Commission and/or Planning Board, if any prior work on the property required filing.

Since all building permits require a plot plan, the Department of Municipal Licenses and Inspections (Building Department) is most likely to have such a plan on file.
