Stretch Code Help Rowley MA - Quick Facts
Local energy code in Rowley
- Rowley 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 Rowley is on the Stretch Code.
What the code requires in Rowley
- A HERS rating is required in Rowley 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 Rowley 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 Rowley Projects
Rowley is a Stretch Code town: the state's adoption list shows it in effect since 2020.
What that means on a Rowley job:
- New homes: HERS 42 if mixed-fuel or HERS 45 if all-electric, or Passive House certification
- Additions and renovations over 1,000 sq ft or over 100% of the existing home: a HERS 65/70 rating on the finished house
- Smaller additions and alterations: REScheck or the prescriptive path
- Commercial: COMcheck for buildings up to 20,000 sq ft
The Rowley Inspection Department issues permits, does inspections and enforces zoning. Permits are filed online through PermitLink, which adds a $12 online service fee.
Electricity comes from the Rowley Municipal Lighting Plant, a municipal light plant, and Rowley is an MBTA Communities (Section 3A) commuter rail community listed by the state as compliant.
The blower door and duct leakage results are what most often hold up a certificate of occupancy, so we schedule a pre-drywall test while air sealing can still be fixed.
A design change during construction, such as different windows or a new heating system, can change the score, so it is worth rerunning the model before the change is made.
Passive House certification is the other route for a new home; it uses its own energy model and on-site testing in place of the HERS target.
A HERS rating scores the finished home against a reference house built to the 2006 energy code, which is set at 100, so a lower number means a more efficient home.
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.
The closest HEEC office to Rowley is Everett, at 371 Main St. We can review plans, run the model and schedule the pre-drywall and final tests around your inspection dates.
