Stretch Code Help Hull MA - Quick Facts
Local energy code in Hull
- Hull 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 Hull is on the Stretch Code.
What the code requires in Hull
- A HERS rating is required in Hull 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 Hull 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 Hull Projects
Hull is still on the state base energy code; the state's adoption list shows no Stretch Code or Specialized (Opt-In) Code adoption for Hull.
On the base code, new homes and additions in Hull can show compliance through the prescriptive path, REScheck or a performance/HERS approach. The fixed HERS caps of the Stretch Code (HERS 42 mixed-fuel or 45 all-electric for new homes, and HERS 65 or 70 for renovations and additions over 1,000 sq ft or over 100% of the existing home) apply only in Stretch and Specialized towns, so they are not required here unless Hull adopts the Stretch Code. Smaller additions and alterations typically use REScheck or the prescriptive tables, and commercial buildings up to 20,000 sq ft can use COMcheck.
Many Hull 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.
In Hull, building permits go through the Building Department. The department's page lists paper applications submitted by mail, in person or through the drop box in front of Town Hall at 253 Atlantic Ave.
Hull homes are served by the Hull Municipal Light Plant, a municipal light plant, so ask the light plant about its own heat pump and efficiency programs before you choose equipment.
Hull 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.
Hull 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.
