Stretch Code Help Danvers MA - Quick Facts
Local energy code in Danvers
- Danvers 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 Danvers is on the Stretch Code.
What the code requires in Danvers
- A HERS rating is required in Danvers 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 Danvers 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.
Mass Save rebates for Danvers (2026)
- For new all-electric homes, 2026 Mass Save pays $7,500 (Base), $15,000 (ENERGY STAR NextGen), or $25,000 (Passive House) per single-family home - up to $40,000 for a 4-unit.

- 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 Danvers Projects
The state's adoption list still shows Danvers on the base energy code, with no Stretch Code or Specialized (Opt-In) Code adoption. That gives new homes in Danvers more flexibility: the prescriptive path, REScheck or a HERS performance approach are all available, and the Stretch Code caps of HERS 42 (mixed-fuel) and 45 (all-electric) only come into play if the town adopts it.
Renovations and additions over 1,000 sq ft or over 100% of the existing home face HERS 65 or 70 targets only in Stretch and Specialized towns. In Danvers, smaller additions and alterations typically use REScheck or the prescriptive tables, and commercial buildings up to 20,000 sq ft can use COMcheck. Many owners still choose a HERS rating, because it documents air tightness and duct testing and keeps the project ready if the town's code changes before the permit is issued.
Building permits in Danvers are handled by Inspectional Services at Town Hall, 1 Sylvan St. Permits can be filed online or in person; the town moved to a new online portal in October 2024, and older permits remain in the PermitEyes system. Electric service in Danvers comes from Danvers Electric, a municipally owned utility, so electric efficiency and heat pump rebates are set by that utility rather than the statewide Mass Save electric programs; check its current offers before choosing heating equipment.
Heating and hot water choices move the score more than most owners expect. A right-sized heat pump, a heat pump water heater and ducts kept inside the conditioned space can bring a design under its target without adding insulation everywhere, so we run those trade-offs in the model before equipment is ordered.
Our process starts with a plan review and energy model so the target score is known before framing. We return for a pre-drywall inspection of insulation and air sealing, then finish with blower door and duct leakage testing so the final certificate is ready for the Danvers final inspection.
