Stretch Code Help Florida MA - Quick Facts
Local energy code in Florida
- Florida is a Stretch Code community - the statewide baseline for new construction and major renovations. IECC Climate Zone 6A.
- Massachusetts has three energy-code levels - base (2021 IECC), Stretch, and Specialized (Opt-In) - and Florida is on the Stretch Code.
What the code requires in Florida
- A HERS rating is required in Florida 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 Florida 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 Florida (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 Florida Projects
The state's adoption list still shows Florida on the base energy code, with no Stretch Code or Specialized (Opt-In) Code adoption. That gives new homes in Florida more flexibility: the prescriptive path, REScheck or a HERS performance approach are all available, and the Stretch Code caps of HERS 42 (mixed-fuel) and 45 (all-electric) only come into play if the town adopts it.
Renovations and additions over 1,000 sq ft or over 100% of the existing home face HERS 65 or 70 targets only in Stretch and Specialized towns. In Florida, smaller additions and alterations typically use REScheck or the prescriptive tables, and commercial buildings up to 20,000 sq ft can use COMcheck. Many 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.
Permit questions in Florida go to Town Hall at 379 Mohawk Trail. The town posts a paper Building Permit Application on its Forms page; we did not find an online portal, so call Town Hall (413-662-2448) to confirm who reviews it.
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.
We model the plans first, flag the details that usually cost points (rim joists, attic hatches and duct runs outside the thermal envelope), verify insulation before drywall, and close out with blower door and duct testing so the Florida inspector receives a finished report.
Our closest office to Florida is in Marlborough at 272 Lincoln St, Suite C1; send plans early and we can tell you which compliance path fits.
