Stretch Code Help Melrose MA - Quick Facts
Local energy code in Melrose
- Melrose has been an Opt-In (Specialized Code) community since July 1, 2024, layering electrification requirements on the Stretch Code; it sits in IECC Climate Zone 5A.
- Beyond the Stretch baseline, new mixed-fuel homes must be pre-wired for future electrification and add on-site solar where there is significant unshaded roof space.
- All-electric new homes must use heat pumps for space heating and hot water; fossil-fuel homes over 4,000 sq ft must reach net-zero (HERS 0), and new multifamily over 12,000 sq ft must meet Passive House.
Melrose code requirements at a glance
- A HERS rating is required in Melrose 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 Melrose 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.
What you can get back: 2026 Mass Save
- New all-electric single-family homes can earn $7,500 to $25,000 from 2026 Mass Save depending on tier (Base, ENERGY STAR NextGen, or Passive House), and up to $40,000 for a 4-unit.
- All-electric renovations and additions: up to $20,000 (Level 1) or $30,000 (Level 2) for a single-family, scaling to $60,000 for a 4-unit; projects that keep fossil fuel use pay-for-savings up to $10,000.
- New multifamily (5+ units): $1,000 to $3,750 per unit by tier (Base, ENERGY STAR, or Passive House), plus a $5,000 feasibility-study incentive and energy-modeling support.
- All Mass Save incentives require verification by a Mass Save-approved, RESNET-certified HERS rater.

Energy Code Path for Melrose Projects
The state's adoption list shows Melrose on the Specialized (Opt-In) Code, effective July 1, 2024. The city had already been on the Stretch Code since January 1, 2011.
Here is how it applies to typical Melrose work:
- New homes: HERS 42 mixed-fuel or HERS 45 all-electric, or Passive House; mixed-fuel homes also need on-site solar and electric pre-wiring
- Homes over 4,000 sq ft: must be all-electric or zero energy
- Multifamily over 12,000 sq ft: Passive House certification
- Additions and renovations: over 1,000 sq ft or more than 100% of the existing home need a HERS 65 or 70 target; smaller work can use REScheck or the prescriptive path
- Commercial: COMcheck for buildings up to 20,000 sq ft
The City Council voted 10 to 1 in December 2023 to adopt the Specialized (Opt-In) Code, effective July 1, 2024.
Melrose also has rail corridor multifamily zoning that the state found compliant with the MBTA Communities Act, so multifamily projects over 12,000 sq ft are a real possibility here.
In Melrose, building permits go through the Department of Inspectional Services. All building, electrical, mechanical, plumbing and gas applications must be submitted through the city's SimpliCity online system.
Changes during construction matter. Swapping windows, insulation or the heating system after the HERS model is done can move the score, so those changes should go past the rater first.
Air sealing is where most scores are won or lost. Rim joists, attic hatches, recessed lights and plumbing penetrations are the usual leaks, so we flag them on the plans and check them before insulation is covered.
Mechanical ventilation is part of every HERS path, and the measured air flow is checked at the final visit along with the blower door number, so the fan and controls should be shown on the plans.
Our Everett office at 371 Main St covers Melrose. 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.

Melrose Specialized Energy Code — HERS Index Targets
Melrose enforces the Massachusetts Specialized (Opt-In) Energy Code. The required HERS score depends on fuel type and project scope — a lower index is stricter.
| Project type | Mixed-fuel | Mixed-fuel + solar | All-electric | All-electric + solar |
|---|---|---|---|---|
| New construction | HERS 42 | 42 | 45 | 45 |
| New construction — embodied-carbon credit | 45 | 45 | 48 | 48 |
| Accessory dwelling unit (ADU) | 52 | 55 | 55 | 58 |
| Major alteration / renovation / change of use | 65 | 70 | 70 | 75 |
A HERS rating is triggered by new construction, additions over 1,000 sq ft (or more than 100% of the existing conditioned area), and Level 3 alterations over 1,000 sq ft affecting more than 50% of the home. New homes must also pass a blower-door test at 3.0 ACH50 and include electrification-ready wiring for heat pumps, EV charging, and solar. We model your Melrose project up front so you know the exact target and the fastest path to hit it — call (617) 501-6788.
