Stretch Code Help Rockland MA - Quick Facts
Local energy code in Rockland
- Rockland enforces the Massachusetts Stretch Energy Code 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 Rockland is on the Stretch Code.
What your project must hit in Rockland
- A HERS rating is required in Rockland 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 Rockland 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 Rockland Projects


The Rockland Building Department takes building, electrical, gas and plumbing permits through PermitEyes. Homeowners can file only building and electrical permits there.
Rockland is a Stretch Code town: the state's adoption list shows it in effect since 2013.
- 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
Rockland is an MBTA Communities (Section 3A) adjacent community and is listed by the state as compliant. The town also runs a community electricity aggregation.
Running the HERS model at the design stage shows whether the walls, windows and heating plan reach the target before anything is ordered.
On a renovation, the rating covers the whole house after the work, so the existing walls and attic can decide whether HERS 65/70 is within reach.
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.
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.
The closest HEEC office to Rockland 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.
