Stretch Code Help Wayland MA - Quick Facts
Local energy code in Wayland
- Wayland adopted the Massachusetts Specialized (Opt-In) Energy Code effective January 1, 2025; the Stretch Code applies as the baseline. 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.
What your project must hit in Wayland
- A HERS rating is required in Wayland 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 Wayland 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.
2026 Mass Save incentives in Wayland
- 2026 Mass Save all-electric new construction: $7,500 (Base) to $15,000 (ENERGY STAR NextGen) to $25,000 (Passive House) per single-family home - up to $40,000 for a 4-unit.

Energy Code Path for Wayland Projects
According to the state's adoption list, Wayland adopted the Stretch Code effective July 1, 2011 and has been on the Specialized (Opt-In) Code since January 1, 2025.
Here is what that means for a Wayland project:
- New homes. HERS 42 for mixed-fuel homes, HERS 45 for all-electric homes, or Passive House certification.
- Large additions and renovations. Projects over 1,000 sq ft or over 100% of the existing home need HERS 65 (mixed-fuel) or HERS 70 (all-electric).
- Smaller additions and alterations. REScheck or the prescriptive path is usually enough.
- Commercial. COMcheck works for commercial buildings up to 20,000 sq ft.
- Specialized (Opt-In) Code rules. 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.
Fuel choice matters early. An all-electric design with heat pumps moves the target from HERS 42 to 45 (or 65 to 70 on a large renovation), which can save money on insulation or windows, so we run those trade-offs in the energy model before equipment is ordered.
Permits in Wayland are handled by the Building Department at 41 Cochituate Road. Most residential and commercial building permits are filed online through Wayland's OpenGov portal, with any remaining hard-copy forms on the department's Forms page.
Wayland is an MBTA adjacent community and is listed as compliant with the Section 3A multifamily zoning law; new multifamily buildings there still have to meet the energy code targets above.
Heating and hot water choices often move the score more than finishes do. A right-sized heat pump, a heat pump water heater and ducts kept inside the conditioned space can bring a Wayland design under its target without adding insulation everywhere.
Timing matters too: the energy model should be done before you file, because the score it predicts is what the final blower door and duct leakage results have to support when the Wayland inspector signs off.
The closest HEEC office to Wayland is Framingham, at 68 South St. We can review plans, run the model and book the testing around your inspection dates.

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