Kingston code requirements at a glance
- A HERS rating is required in Kingston 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 Kingston 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 Kingston Projects
Kingston is a Stretch Code community. The state's adoption list shows the Stretch Code in effect there since January 1, 2011, so the current Stretch Code, not the base code, sets the energy targets for Kingston permits.
The rules below decide which compliance path a Kingston project takes.
- New homes: HERS 42 for mixed-fuel homes, HERS 45 for all-electric homes, or Passive House certification.
- Large additions and renovations: Work over 1,000 sq ft, or over 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 works for buildings up to 20,000 sq ft.
Hitting a HERS 42 or 45 target is mostly about the envelope: continuous air sealing at the rim joists, attic hatches and penetrations, insulation installed without gaps, and balanced ventilation sized to the tested air tightness.
How a typical Kingston project moves through the energy code:
- We model the plans and set the HERS target before you apply.
- The energy paperwork goes in with the permit application.
- We inspect insulation and air sealing before drywall.
- Final blower door and duct tests confirm the score for the final inspection.
In Kingston, building permits go through the Building, Inspections and Zoning department. Applications are filed online through SmartGov.
Kingston is on the state's list of MBTA Communities with compliant multifamily zoning, and multifamily projects built under that zoning follow the same energy code tier as any other permit in town.
Kingston projects are served from our Somerville office at 519 Broadway. We review plans before you file, inspect insulation and air sealing before drywall, and run the final blower door and duct tests.
