Energy Code Compliance: The Part That Holds Up Most Permits

Milton's Specialized Code took effect January 1, 2025 (state list); it had the Stretch Code from July 1, 2011.

At permit: New homes and large additions need a projected HERS rating report from a RESNET-certified rater.

At final: At final we run the blower door and duct leakage tests and issue the confirmed HERS certificate.

Project	Energy document
New home	Projected HERS report (HERS 42 mixed-fuel / 45 all-electric)
ADU	Projected HERS report (HERS 52 / 55)
Addition over 1,000 sq ft or over 100% of the home	Projected HERS report (HERS 65 / 70)
Smaller addition or alteration	REScheck or the prescriptive path, if the inspector accepts it
Commercial up to 20,000 sq ft	COMcheck plus a whole-building blower door test

Home Energy Efficiency Consultants prepares the projected HERS report from your plans, usually in about one business day after the quote is accepted, then does the pre-drywall inspection, blower door and duct leakage tests and the confirmed HERS certificate. See our stretch code report for permitting page for what's in the report, EV-ready and solar-ready rules, and when Phius applies.
