Stretch Code Help Paxton MA - Quick Facts
Local energy code in Paxton
- Paxton 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 Paxton is on the Stretch Code.
What the code requires in Paxton
- A HERS rating is required in Paxton 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 Paxton 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 Paxton Projects
The Paxton Building Department takes building permit applications online through the town's online permitting system.
The state's adoption list shows Paxton on the base energy code, with no Stretch Code or Specialized (Opt-In) Code adoption. That changes which compliance path a project can take:
- New homes: the prescriptive path, REScheck or a performance/HERS approach; the Stretch Code HERS 42/45 caps do not apply
- Additions and renovations: REScheck or the prescriptive tables, with no HERS 65/70 target unless the town adopts the Stretch Code
- Commercial: COMcheck for buildings up to 20,000 sq ft
Electricity in town comes from the Paxton Municipal Light Department, a municipal light plant, and state utility data lists no natural gas service in Paxton, so most new homes are planned around electric heat or delivered fuel.
Paxton appears on the state's list of MBTA Communities (Section 3A) that are compliant.
Even on the base code, the blower door and duct leakage tests still have to pass at final, so the air sealing details are the same as on a Stretch Code job.
On most jobs the rater visits twice: at pre-drywall to check insulation and air sealing while they can still be fixed, and at final for the blower door, duct leakage and ventilation tests.
REScheck compares the planned insulation, window and air sealing values with the code tables, which suits small additions and alterations with a simple envelope.
The energy paperwork is reviewed when the permit is issued and again before the certificate of occupancy, so the final report should match the approved plans.
Heat pump sizing, duct location and the ventilation plan are easiest to settle before framing, and those choices move the HERS score more than most finishes do.
The closest HEEC office to Paxton is Marlborough, at 272 Lincoln St C1. We can review plans, run the model and schedule the pre-drywall and final tests around your inspection dates.
