The application steps and inspection sequence for solar permits come from the model code rather than from Massachusetts law, so they read the same wherever you build. We keep that walkthrough in one place: how a solar permit application and its inspections work, start to finish. What changes between Massachusetts jurisdictions is below: who requires a permit, what they charge, and which office you file with.

Hire it out

Before you sign, ask the contractor:

  • Who pulls the permit, you or me, and is the permit fee included in the bid?
  • Which inspections will this job need, and who meets the inspector on site?
  • Is your Massachusetts Office of Consumer Affairs and Business Regulation license active, and under which business name? Verify it on contractorhub.mass.gov.
