Zoning, building permits and septic rules in Town of Hanover, Massachusetts

Town of Hanover’s own rules

• Building permitRequired

  Construction, reconstruction, repair, alteration and demolition of buildings and structures inside Hanover town

  • The building department issues building, electrical and plumbing permits; work proceeds after permit issuance.
  • Permit fee and exemption thresholds were not located in the page reviewed.

  “the building department issues building, electrical, and plumbing permits. these permits allow the construction, reconstruction, repair, alteration, and demolition of buildings and structures, as well as the installation of equipment.”

• Local zoningPresent (with conditions)

  Land inside Hanover town's limits is governed by the Hanover Zoning Bylaw adopted by Hanover town meeting.

  • The town's bylaws page lists the Hanover Zoning Bylaw as amended through the December 8, 2025 annual town meeting; the bylaw PDF itself could not be read in this session (the PDF text extraction failed), so its contents are unverified.
  • Bylaws are enacted by town meeting and approved by the Massachusetts Attorney General's office, per the same page.

• Permit processPartial

  Building, electrical and plumbing permit applications for work inside Hanover town

  • Applications are filed through the town's OpenGov online permitting portal; the page describes registering and using the portal.
  • Fee schedules and step-by-step review procedures were not read, so the process is only partly documented here.

Rules another office applies inside Town of Hanover

Town of Hanover does not set these itself; the county, a health district or the state does, and they apply to every address inside its limits.

• Building code adoptedAdopted

  Building construction, alteration and repair inside Hanover town, enforced by the Hanover building department

  • The Massachusetts State Building Code is the code the Hanover building department enforces; this is a state rule, not a Hanover-adopted code.

  “the building department enforces the commonwealth of massachusetts building code and the hanover by-laws.”
