Why local experience matters
Local experience helps ensure your project is reviewed with Massachusetts requirements, practical construction details, and real jobsite conditions in mind.
What the process may include
Depending on the project, the process may include plan review, energy modeling, field verification, and final testing support.
Our 5-Step HERS Rating Process in Stoughton
A Stoughton project flows through five distinct milestones, from the permit set at the start to the certificate that seals it at the end — here is how HERS verification handles each one.
Plan Review & Preliminary Report
We review your blueprints and produce the preliminary energy report your building permit requires before construction begins.
Equipment Consulting
Before anything is installed, we confirm your appliances and equipment are correct — a crucial step many companies skip, so you never buy the wrong system.
Mid-Point Inspection
We inspect during construction to make sure insulation is installed correctly and to the code requirements of your HERS report.
Final Testing
Blower-door testing, duct testing, and ERV balancing. ERV balancing is vital — done wrong it can cause pressure issues throughout your home.
Final Certificate
We send over the final certificate to close out your building permit and apply for your Mass Save rebates.
Stoughton and the Massachusetts Specialized Stretch Code
A Norfolk County town in Climate Zone 5A, Stoughton follows the Specialized Stretch Code — the most demanding energy standard in Massachusetts, which knits electrification-readiness into the usual efficiency requirements.
Solar-Ready (RB102)
A newly built Stoughton home must hold back open roof space and pre-run conduit, so a solar array can be installed later without significant rework.
EV-Ready (RB103)
Because panel capacity and a dedicated circuit are prepared in advance, adding a Level 2 charger to a Stoughton garage is quick and affordable.
Talk directly with the owner
Owner and Mass Save partner Dominic Zammuto personally leads every Stoughton rating — so you deal with the expert, not a call center. Ask anything about your project or the incentives you can claim.

100 is the starting line
A reference house registers 100, while each Stoughton home we rate is engineered to land comfortably below it.
0 equals net-zero
A zero on the index means a Stoughton home produces as much energy as it draws — the height of efficient design.
About 1% per point
Shave off one point and energy use drops by roughly one percent — real money back in the Stoughton owner’s pocket.
How We Confirm Performance on a Stoughton Rating
- ✅ Energy modeling — before construction we build a performance model of the Stoughton home to forecast energy use room by room.
- ✅ Blower-door testing — a calibrated fan reveals precisely how airtight the finished Stoughton home is.
- ✅ Duct-leakage testing — we measure how much conditioned air the ductwork loses so none of it is wasted.
Connecting HERS and the Stretch Code in Stoughton
- ✅ Stoughton builds on the IECC 2021 model code and layers Massachusetts’ stricter energy goals over it.
- ✅ The HERS score you must hit is set by fuel type — all-electric and mixed-fuel homes carry separate targets.
- ✅ We link your rating to Mass Save incentives and the official Mass.gov stretch code rules.

FAQ About HERS Rating Stoughton MA
Common questions about HERS ratings in Stoughton, Massachusetts.
What is a HERS rating?
A HERS (Home Energy Rating System) rating is the national industry standard for measuring a home's energy efficiency. A certified HERS Rater reviews the plans and performs on-site inspections and testing, including a blower door test, to produce a score. Lower is better: a standard new home built to 2006 code scores 100, while a net-zero home scores 0.
What is a good HERS score?
Any score below 100 beats a standard new home, and the lower the number the more efficient the home. A score of 50 means the home is about 50% more efficient than a standard new build, while older unimproved homes often score 130 or higher. Massachusetts code targets are now well below 100.
How have Massachusetts HERS requirements changed in recent years?
Massachusetts has steadily tightened the maximum allowable HERS score. The required score for new homes was around 55 in 2022, dropped to 52 in 2023, and tightened to HERS 42 for mixed-fuel homes and 45 for all-electric homes as of July 1, 2024. The 2023 update also adopted the 2021 IECC as the base code and removed the earlier 5-point HERS credit for rooftop solar, pushing toward efficiency and electrification.
How much does a HERS rating in Stoughton cost?
A HERS rating in Stoughton typically costs:
- Single-family homes: $1,850–$2,500
- Accessory dwelling units (ADUs): $1,600–$1,850
- Multifamily: $900–$1,450 per unit
Final pricing depends on home size, complexity, and the number of required site visits.
What HERS score do I need to pass in Stoughton?
As of July 1, 2024, new construction needs a HERS 42 for homes using any fossil fuel and a HERS 45 for all-electric homes, verified by a certified RESNET HERS rater. Low-emission concrete comes in around 45 with gas or 48 all-electric, an ADU is 55 all-electric or 52 with gas, and multifamily matches the single-family requirement.
What triggers a HERS rating in Stoughton?
New construction almost always requires one. Under energy code Section R502, an addition triggers a HERS rating when the added conditioned floor area exceeds 1,000 square feet or doubles the size of your existing conditioned space (more than 100% of the existing conditioned floor area), requiring the combined dwelling to meet the maximum HERS ratings in Table R406.5.
Do renovations or alterations require a HERS rating?
They can. Under Section R503, extensive alterations (or IEBC Level 3 alterations) that exceed 1,000 square feet or double the size of the existing conditioned space (over 100% of the existing conditioned floor area) must meet the maximum HERS ratings in Table R406.5. Smaller alterations must still meet component requirements for insulation, replacement windows, water heating, and lighting.
Do I need a HERS rating in Stoughton?
If Stoughton has adopted the Massachusetts Stretch Energy Code, then yes for new homes, larger additions, and extensive renovations. A certified HERS rater can confirm whether your specific project triggers the requirement.
What kind of windows do I need to meet the new energy code?
All-electric homes favor a U-value of .25/.26 with an SHGC of .42 or higher, while gas homes favor tighter values. For replacements specifically, Section R503.1.1.1 requires new units, including sash and glazing, to meet the U-factor and SHGC in Table R402.1.3.
What kind of insulation do I need to pass a HERS rating?
You generally need around R-21 to R-30 depending on whether you go gas or all-electric.
What if I do not want to use spray foam?
You can use exterior insulation and then use mineral wool inside the wall.
How can I build to energy code in a cost-effective way?
Using low-emission concrete can reduce the HERS score by about 3 points, saving close to $20k or more between systems and upgrades.
What is an ERV system and do I need it in Stoughton?
Yes, it is now required by code. You can use an ERV or HRV to satisfy the requirement for balanced mechanical ventilation.
How much CFM do I need for my ERV?
It is based on bedrooms, square footage, and insulation volume, along with the ACH from your blower door test.
What do I need to start a HERS rating?
You need a set of architectural plans and to know whether you will go gas or all-electric.
How can I improve my score and what affects my score?
Your score is affected by windows, insulation, HVAC, and appliances such as the washer, dryer, dishwasher, and fridge.
Does a HERS rating add value to my home?
Yes. Energy-efficient HERS-rated homes have been shown to sell at a premium over comparable standard homes, on top of ongoing savings from lower utility bills.
Are there rebates for a HERS rating in Stoughton?
Yes. Working with a certified HERS rater can unlock Mass Save incentives for new construction and renovations.
Where can I find a HERS rater near Stoughton?

HERS Score Requirements in Stoughton by Year
Massachusetts Stretch Energy Code HERS thresholds have tightened over time. These are the maximum HERS Index scores required to pass for new construction, based on when the building permit was filed.
| Time Frame | Required HERS Score |
|---|---|
| 2022 | New homes: HERS 55 or lower |
| Effective Jan 1, 2023 | New homes: HERS 52 or lower |
| Effective July 1, 2024 (current) | HERS 42 for homes using any fossil fuel; HERS 45 for all-electric homes |
| Major remodels, additions & change-of-use | Generally HERS 65 to 75 |
| ADUs (per recent updates) | Around HERS 52 mixed-fuel / 55 all-electric |
Curious about the steadily dropping target? Massachusetts has tightened its HERS requirements year after year — declining from about 55 to 52 and now toward 42 for fossil-fuel homes and 45 for all-electric homes in Stoughton. Each tightening carries new construction nearer net-zero, and that is exactly why planning early and modeling precisely pay off on a Stoughton project.
Note: HERS requirements are set by the Massachusetts Stretch and Specialized Energy Codes and can change with code updates. Figures reflect the current code at the time of writing.
