Building Permit Information and Forms

The Massachusetts State Building Code (780 CMR) allows Building Departments thirty (30) days to act on a building permit application. Building permits are usually issued within ten days assuming all required information detailed below is provided at the time of original submission.

1 - The Building Permit Application must be completed with the following information:

  • Property address
  • Owner Name, Address, and Phone Number
  • Description of work
  • Cost of project
  • Contractor License information
  • Signature of the homeowner or his/her authorized agent
  • The Building Permit Fee is based on $15.00 per $1,000 of construction cost (rounded up a thousand) with a minimum fee of $50.00.

2 - The Debris Form must be completed indicating where debris from the construction site will be disposed. Note: The Town’s residential trash collection does not include construction debris

3 - The Workers’ Compensation Insurance Affidavit must be completed by the license contractor or the homeowner performing the work.

4 - The Homeowner License Exemption Form is required for work involving a single or two-family residence if: the contractor does not have a State Construction Supervisors License, or the homeowner is seeking the building permit.

5 - Certified Plot Plan stamped by a Massachusetts Registered Land Surveyor must be submitted with every building permit application for the construction of a new building, an accessory building, or an addition to an existing building.  All plans must conform to the “Regulations for Plot Plans for Building Permits” and must include existing and proposed open space and lot coverage percentages.

6 - Construction drawings for new construction or interior alterations (interior renovations without structural alterations do not require plans - code compliance will be determined during inspections)

  • Plans and Specifications: Every application must be accompanied by one (1) copy, two (2) if adding a bedroom of specifications, and plans drawn to scale with sufficient clarity, detail and dimensions to show the nature and character of the work to be performed. All plan sets larger than 11x17 must also include an emailed pdf version or CD of the plans. This information will be thoroughly reviewed to determine code compliance.  The degree of completeness and accuracy will have a direct bearing on the time required for review and approval.  Plans should include but not be limited to:
    1. Foundation plan with anchor bolt locations and clearly showing a minimum four (4) foot depth to bottom of all footings.
    2. Structural, mechanical and electrical plans in sufficient detail to determine code compliance.  (Include exterior building envelope component materials with R-values, heat loss information, HVAC sizing, etc. for energy code compliance in accordance with Appendix J of 780 CMR Massachusetts State Building Code.)
    3. All plans and specifications for any building containing more than 35,000 cubic feet of enclosed space, except single or two-family dwelling(s), must be stamped and signed by a qualified registered professional engineer or architect.
