Stretch Code Help Huntington MA - Quick Facts
Local energy code in Huntington
- Huntington is a Stretch Code community - the statewide baseline for new construction and major renovations. IECC Climate Zone 5A.
- Massachusetts has three energy-code levels - base (2021 IECC), Stretch, and Specialized (Opt-In) - and Huntington is on the Stretch Code.
What the code requires in Huntington
- A HERS rating is required in Huntington for: new construction; additions over 1,000 sq ft (or greater than 100% of the existing conditioned floor area); and extensive Level 3 alterations over 1,000 sq ft affecting more than 50% of the conditioned floor area.
- New home, mixed-fuel (gas heat, hot water or cooking): must reach HERS 42 or lower.
- New home, all-electric: must reach HERS 45 or lower.
- Embodied-carbon materials credit: allows up to HERS 48.
- ADU, mixed-fuel (gas): HERS 52; ADU, all-electric: HERS 55; ADU with the embodied-carbon credit: HERS 58.
- Major additions and renovations: HERS 65 (mixed-fuel) or HERS 70 (all-electric).
- Air tightness: a blower door test at 3.0 ACH50 or tighter; duct leakage capped at 4.0 CFM25 per 100 sq ft total leakage (8.0 when all ducts are inside conditioned space - the test is still required).
- Also required in new homes: whole-house mechanical ventilation (ASHRAE 62.2) and EV-ready wiring; compliance runs through the HERS / Energy Rating Index path (2025 code section R406).
How compliance is verified
- Energy model from your plans, a pre-drywall (rough) inspection, blower door and duct leakage testing, then a final HERS certificate filed with the Huntington building department.
- Same-day preliminary HERS reports; blower door and duct results in 24-48 hours, with fail-fix guidance if a home misses the target.

Energy Code Path for Huntington Projects
According to the state's adoption list, Huntington has used the Stretch Code since January 1, 2013. Every residential permit in town is reviewed against the current Stretch Code requirements.
What the code asks of Huntington projects:
| Project type | Requirement in Huntington |
|---|---|
| New homes | HERS 42 for mixed-fuel homes, HERS 45 for all-electric homes, or Passive House certification. |
| Large additions and renovations | Work over 1,000 sq ft, or over 100% of the existing home, targets HERS 65 (mixed-fuel) or HERS 70 (all-electric). |
| Smaller additions and alterations | REScheck or the prescriptive path is usually enough. |
| Commercial | COMcheck works for buildings up to 20,000 sq ft. |
Hitting a HERS 42 or 45 target is mostly about the envelope: continuous air sealing at the rim joists, attic hatches and penetrations, insulation installed without gaps, and balanced ventilation sized to the tested air tightness.
In Huntington, building permits go through the Building Department. Confirm the current application method with that office before you submit.
Duct leakage counts too. Ducts outside the conditioned space have to be sealed and tested, and keeping them inside the thermal envelope makes the target much easier to reach.
Equipment choices move the score as much as insulation does: a right-sized heat pump, a heat pump water heater and efficient windows can each take points off the HERS index.
Timing matters as well. The energy documents have to match the plans on file, so changes to windows, insulation or mechanical equipment during construction should go past the rater before they are made, not after.
Our Marlborough office at 272 Lincoln St C1 covers Huntington. Sending us the plans before the permit application lets the HERS, REScheck or COMcheck paperwork go in with the submission instead of holding up plan review.
