Stretch Code Help Swampscott MA - Quick Facts
Local energy code in Swampscott
- Swampscott 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.
Swampscott code requirements at a glance
- A HERS rating is required in Swampscott 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 Swampscott 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 Swampscott Projects
Swampscott was a Stretch Code community from January 1, 2011, and the state's adoption list shows the Specialized (Opt-In) Code in effect there since July 1, 2024.
Attach the HERS, REScheck or COMcheck paperwork when you apply so the energy review runs with plan review instead of after it.
Here is how it applies in Swampscott:
- 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
- Specialized (Opt-In) Code extras: new homes over 4,000 sq ft must be all-electric or zero energy, and multifamily buildings over 12,000 sq ft must meet Passive House
In Swampscott, permits go through the Building Department at 22 Monument Ave. Permits are filed through the town's OpenGov licensing and permitting portal.
Swampscott is not one of the communities in DOER's Municipal Fossil Fuel Free Building Demonstration Program, so the energy code, not a local fossil fuel ban, sets the rules for heating fuel.
Mixed-fuel homes also carry electric-ready wiring requirements, so the panel and circuit layout belong on the plans early.
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).
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.
HEEC serves Swampscott from our Everett office at 371 Main St, handling HERS ratings, blower door and duct testing, and REScheck or COMcheck reports.

Swampscott Specialized Energy Code — HERS Index Targets
Swampscott 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 Swampscott project up front so you know the exact target and the fastest path to hit it — call (617) 501-6788.
