Use the city permit portal and the Inspectional Services Department resources cited below to start your application and confirm any project-specific requirements.

Permitting overview

The Inspectional Services Department (ISD) administers building and electrical permits for photovoltaic (PV) systems in Boston; submit plans and fee payments through the city permit portal. For general municipal guidance see the ISD solar permit page City of Boston ISD - Solar PV Permitting[1]. Typical submissions include construction drawings, single-line electrical diagrams, roof structural info, and an owner/contractor affidavit.

Obtain building and electrical permits before installation to avoid stop-work orders.
  • Required documents: plans, single-line diagram, roof plan, installer license evidence.
  • Fees: amounts vary by project and are set at permit review; specific fee amounts are not specified on the cited page.
  • Typical review time: varies by scope; check the portal for current processing times.
  • Inspections: electrical and rooftop framing inspections required before final approval.

Penalties & Enforcement

Enforcement of rooftop solar permitting and related building-code compliance in Boston is carried out by the Inspectional Services Department. Enforcement actions can include orders to stop work, inspection notices, and formal enforcement under the Boston Municipal Code and applicable state building codes.
