Dalton code requirements at a glance
- A HERS rating is required in Dalton 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 Dalton 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.

Energy Code Path for Dalton Projects
The Stretch Code has applied in Dalton since July 1, 2015, according to the state's municipal adoption list. Every new single-family home or townhouse in Dalton is rated against a HERS cap of 42 for mixed-fuel designs or 45 for all-electric designs, with Passive House certification as the other option.


Which path applies to a Dalton project depends on its scope:
- New homes: HERS 42 mixed-fuel, HERS 45 all-electric, or Passive House.
- Renovations and additions 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.
Building permits in Dalton are handled by the Building Department under the Building Commissioner. Applications are filed online through PermitEyes on the shared Berkshire portal, as described in the town's permitting guidebook.
Air sealing is where most scores are won or lost. Attic hatches, rim joists, recessed lights and plumbing penetrations are the usual leaks, so we mark them on the plans and check them on site before insulation is covered. Balanced ventilation sized to the tested air tightness keeps the house healthy once it is tight.
Submitting the HERS, REScheck or COMcheck paperwork with the permit application lets the energy review run alongside plan review instead of after it. We prepare those documents, inspect insulation and air sealing before drywall, and run the final blower door and duct tests.
Dalton projects are served from our Marlborough office at 272 Lincoln St, Suite C1, and a quick plan review before you file usually saves a round of permit comments.
