Scope & Applicable Codes

New Haven enforces energy conservation requirements through locally administered building permits and inspections tied to the Connecticut State Building Code and its energy-related provisions.

Local permitting and submission rules are managed by the City of New Haven Building Division; check the city permit pages for application steps and contact info (New Haven Building Division)[1].

Start permit planning early to avoid delays in energy compliance reviews.

Applications & Forms

The City of New Haven issues building and mechanical permits through its permits portal. Where published, building permit applications, mechanical permit forms, and checklist items are available from the city permit pages; if a specific energy compliance form is required it will be listed with the permit instructions. If no energy-specific form is published for a particular permit type, the city accepts standard permit submission materials and energy compliance reports as part of the plan package.[1]

How to Comply - Practical Steps

  1. Plan: review applicable state energy code sections and identify compliance path (prescriptive or performance).
  2. Prepare permit documents: include energy compliance forms, REScheck/COMcheck outputs or energy model reports, and labeled plans.
  3. Submit: file the permit application with the City of New Haven Building Division via the official permits portal.
  4. Inspect: schedule and pass required inspections (rough, envelope, final), provide test results and commissioning reports if required.
  5. Closeout: obtain final approval and certificate of occupancy only after energy compliance items are verified.
Keep copies of compliance reports and inspection sign-offs with the project file.
