Building Permits

When is a Building Permit Required?

• Anyone seeking to construct, reconstruct, alter, repair, or demolish a structure or install a sign must first obtain a building permit at the Inspectional Services Division (ISD).
• Per Somerville Zoning Ordinance and Massachusetts State Building Code (780 C.M.R.), a building permit must be obtained before the start of any work and must be prominently displayed at the job site. All building permits require the same four to five documents; some projects may require additional permits. You can find the necessary permits by clicking the "Apply for a License or Permit" button below.
• Interior gutting requires a building permit, not a demolition permit. Total teardowns require a demolition permit. Read more about demolition permits here.
• A building permit signifies that the proposed use or structure is meeting zoning prerequisites (e.g.; setback, frontage, or minimum yard-size requirements) and the State Building Code.
• Ordinary repairs, as defined in the Building Code, such as painting and tiling, do not require a building permit.
• If you are unsure if you require a building permit or to schedule a preliminary meeting with a building inspector please call ISD at 617-625-6600 ext. 5600, or e-mail isd@somervillema.gov.
