Stretch Code Help Bedford MA - Quick Facts
Local energy code in Bedford
- As of July 1, 2024, Bedford enforces the Massachusetts Specialized (Opt-In) Energy Code on top of the Stretch Code baseline - IECC Climate Zone 5A.
- The Opt-In code goes further than the Stretch baseline: new fossil-fuel homes must be pre-wired for electrification and include on-site solar where roof space allows.
- New all-electric homes rely on heat pumps for heat and hot water; large fossil-fuel homes over 4,000 sq ft must hit net-zero (HERS 0), and multifamily over 12,000 sq ft must be Passive House.
What the code requires in Bedford
- A HERS rating is required in Bedford 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 Bedford 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 Bedford (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.
- 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 Bedford Projects


Since July 1, 2024, Bedford projects fall under the Specialized (Opt-In) Code; before that the town had been a Stretch Code community since January 1, 2012.
Here is how the targets break down for a Bedford permit:
- New homes: HERS 42 for mixed-fuel homes, HERS 45 for all-electric homes, or Passive House certification.
- Large additions and renovations: Work adding over 1,000 sq ft, or more than 100% of the existing home, targets HERS 65 (mixed-fuel) or HERS 70 (all-electric).
- Smaller additions and alterations: REScheck or the prescriptive path is usually enough.
- Commercial: COMcheck covers commercial buildings up to 20,000 sq ft.
Because Bedford is a Specialized (Opt-In) Code town, it adds net-zero-ready rules on top of the Stretch Code targets: 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. Mixed-fuel homes also need to be pre-wired for future electrification and generally include on-site solar.
Think of the HERS target as a budget for the whole house; in Bedford we balance walls, windows and equipment against it before anything is ordered.
Fuel choice matters early in Bedford: an all-electric heat pump design moves the target from HERS 42 to 45 (or 65 to 70 on a large renovation), which can save money on insulation or windows.
The Code Enforcement Office reviews Bedford building permits; applications are filed online through PermitEyes. Plan the final blower door and duct tests so the paperwork is in hand before the Bedford final inspection. Attach the HERS, REScheck or COMcheck paperwork when you apply so the energy review runs with plan review instead of after it.
The nearest HEEC location for Bedford is our Somerville office at 519 Broadway, and we are happy to review plans before you apply.

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