Stretch Code Help Upton MA - Quick Facts
Local energy code in Upton
- Upton 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 Upton is on the Stretch Code.
What the code requires in Upton
- A HERS rating is required in Upton 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 Upton 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 Upton Projects
Upton adopted the Stretch Code, and the state's adoption list shows it in effect since January 1, 2015.
Permits in Upton are handled by the Code Enforcement Department. Permits can be applied for online through the town's PermitPro link, and paper PDF forms are posted as well.
Upton is on the state's list of MBTA Communities found compliant with the multifamily zoning law, so a multifamily project in its zoning district should line up the energy path with zoning review from the start.
The numbers to plan around in Upton:
- New homes: HERS 42 if mixed-fuel, HERS 45 if all-electric, or Passive House certification
- Additions and renovations over 1,000 sq ft or over 100% of the existing home: HERS 65 (mixed-fuel) or HERS 70 (all-electric)
- Smaller additions and alterations: REScheck or the prescriptive path
- Commercial buildings up to 20,000 sq ft: COMcheck
Attach the HERS, REScheck or COMcheck paperwork when you apply so the energy review runs with plan review instead of after it.
A pre-drywall inspection is the cheapest point to fix air sealing and insulation gaps, long before the final blower door test.
A typical sequence is a plan review and energy model before the permit, a pre-drywall walk-through to catch gaps in insulation and air sealing, and the final blower door and duct tests that close out the energy paperwork.
Decide on fuel before the design is final: an all-electric home gets the easier HERS 45 target (70 for a large renovation) instead of 42 (65).
Upton projects are handled from our Framingham office (68 South St). We model the plans, inspect before drywall and run the final blower door and duct tests.
