Quick Answers
Do I need a HERS rating in Raynham, MA?
Yes, in most cases. Massachusetts requires a HERS rating for new residential construction and for large additions or major renovations in communities that follow the Stretch or Specialized Energy Code. A preliminary HERS rating is typically needed for the building permit and a final rating for the certificate of occupancy.
What HERS score is required in Raynham, MA?
Under the 2025 Massachusetts Stretch Code, new mixed-fuel homes need HERS 42 or lower and all-electric homes 45 or lower; an embodied-carbon credit for low-GWP insulation or concrete adds 3 points. Major additions and Level 3 renovations use separate targets (HERS 65 mixed-fuel / 70 all-electric) and ADUs 52-58. We confirm the exact path for your Raynham project.
How much does a HERS rating cost in Raynham, MA?
Most Massachusetts HERS ratings run from about $600 to $2,500 depending on the size and scope of the project. Call (617) 501-6788 for a free same-day quote for your Raynham project.

HERS Rating Raynham MA Facts
Helpful answers for homeowners, builders, and developers planning a project in Raynham.
Raynham ( ) is a town in Bristol County, Massachusetts, United States, located approximately 32 miles (51 km) south of Boston and 22 miles (35 km) northeast of Providence, Rhode Island. The population was 15,082 at the 2020 census. Raynham is located in Bristol County, Massachusetts. The 02767 area, like the rest of Massachusetts, sits in IECC climate zone 5A, which shapes insulation, air-sealing, and HVAC requirements for HERS rating and energy code compliance.
Where does HERS rating apply in Raynham?
New construction, additions, and major renovations in Raynham, Bristol County are reviewed against the Massachusetts energy code, and a HERS rating is the standard way to document compliance.
What climate zone is Raynham in?
Like all of Massachusetts, Raynham is in IECC climate zone 5A, which sets the insulation, air-sealing, and mechanical-system targets a HERS rater verifies.
Do existing homes in Raynham need a HERS rating?
Most existing homes only need a rating for major renovations, additions, or energy-code permits; new construction in Raynham almost always requires one.
How does a HERS rating help Raynham homeowners?
A lower HERS Index signals a more energy-efficient home, lower utility bills, and easier code compliance for projects in Raynham.
What is a HERS Rating?
A HERS Rating measures the energy efficiency of a home and is commonly used for new construction, additions, and major renovations in Massachusetts.
Who may need one?
Builders, homeowners, and developers in Raynham may need a HERS rating depending on project size, code path, and permit requirements.
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 Raynham
From your first permit set to your final certificate, set out below is the orderly, one-step-and-then-onward routine we lean on to steer a Raynham project through HERS verification from footing to final report.
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.
Raynham and the Massachusetts Energy Code
Located in Bristol County and sitting in Climate Zone 5A, Raynham has not adopted the Stretch Code and follows the Massachusetts base energy code. The two Stretch Code features below would apply if Raynham adopts it, and they are still worth planning for.
Solar-Ready (RB102)
Under the Stretch Code, a new home must set aside clear roof area and pre-installed conduit so solar panels can be added later without major rework.
EV-Ready (RB103)
Panel capacity and a dedicated circuit are prepared in advance so adding a Level 2 charger in your Raynham garage is quick and inexpensive.
Talk directly with the owner
Dominic Zammuto, the owner and a Mass Save®-listed HERS rater, personally oversees every Raynham rating — you deal with the expert, not a call center. Ask anything about your project or the incentives you can claim.
Explore Mass Save RebatesWhat the HERS Index Means for Raynham Homes
100 is the starting line
A reference home scores 100. Every Raynham home we rate is engineered to finish comfortably below it.
0 equals net-zero
A zero on the index means your Raynham home makes as much energy as it burns — the topmost point that carefully-detailed, energy-thrifty design can hope to reach.
About 1% per point
Shave a single point and you trim roughly one percent from energy consumption — real money back in a Raynham owner’s pocket.
How We Confirm Performance on a Raynham Rating
- ✅ Energy modeling — we build a performance model of your Raynham home before construction to forecast energy use room by room.
- ✅ Blower-door testing — a calibrated fan reveals exactly how airtight the finished Raynham home really is.
- ✅ Duct-leakage testing — we measure how much conditioned air the ductwork loses so nothing goes to waste.
Connecting HERS and the Energy Code in Raynham
- ✅ Raynham builds on the IECC 2021 model code and adds Massachusetts’ stricter energy goals on top.
- ✅ Under the Stretch Code, the HERS target depends on fuel type — all-electric and mixed-fuel homes have separate targets.
- ✅ We link your rating to Mass Save incentives and the official Mass.gov stretch code rules.

Raynham HERS Targets: 2025 Code Charts
Raynham is on the base energy code, so these HERS targets are not mandatory here. They show what applies in Stretch Code and Specialized (Opt-In) Code towns and are a useful benchmark if you choose the HERS path.
Raynham HERS Index Scale and More 2025 Code Graphics
How to Read a HERS Report for Your Raynham Home
Every Raynham project we rate gets a HERS certificate like this one. Here is what each part means. The sample is a real HEEC projected report (HERS 45, all-electric duplex) with the address, builder and rater details removed.
Building and Permitting in Raynham
Raynham builds to the base energy code
Raynham has not adopted the Massachusetts Stretch Code. New homes and renovations in town follow the Massachusetts base energy code, so the HERS 42/45 limits you may hear about are not required here.
For context, these are the Stretch and Specialized (Opt-In) Code targets that apply in neighboring towns that adopted them, and that would apply in Raynham if the town adopts the Stretch Code later:
- New homes: HERS 42 mixed-fuel, HERS 45 all-electric
- Additions or renovations over 1,000 sq ft or over 100% of the existing home: HERS 65 mixed-fuel, HERS 70 all-electric
- Accessory dwelling units: HERS 52 mixed-fuel, HERS 55 all-electric
Why order a HERS rating anyway?
A rating is still useful in a base-code town. Builders use it for ENERGY STAR certification, and buyers increasingly ask for a HERS score as proof of a tight, efficient house. A preliminary rating from your plans also tells you how close you are to Stretch-level performance before the house is framed.
Electric service
Raynham gets its electricity from the Taunton Municipal Lighting Plant (TMLP), a municipal light plant. Because of that, Mass Save electric incentives may not apply to your project, so check with TMLP about the programs it offers before you count on a rebate.
Permits in Raynham
The Raynham Building Department is at 558 South Main Street, phone (508) 824-2708. It is open Monday to Thursday 8:30 am to 4:30 pm, Tuesday evenings 6 to 8 pm, and Friday 8:30 am to noon. The town has offered online permitting since 2020. Before submitting a residential or commercial application, the department asks you to call to find out which sign-offs your type of construction needs.
Zoning for more housing
At Town Meeting on May 19, 2025, voters approved Article 36, creating a multi-family overlay district of about 50 acres to meet the MBTA Communities law, with a theoretical build-out of up to 764 units, according to local news coverage. Raynham is listed as compliant on the state's MBTA Communities approval list as of August 27, 2026.
HEEC's nearest office to Raynham is in Framingham at 68 South St.
FAQ About HERS Rating Raynham MA
Common questions about HERS ratings in Raynham, 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 Raynham cost?
A HERS rating in Raynham 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 Raynham?
Raynham follows the Massachusetts base energy code, so there is no Stretch Code HERS target to pass there today. In Stretch Code towns, as of July 1, 2024, new construction needs HERS 42 for homes using any fossil fuel and HERS 45 for all-electric homes, and an ADU needs HERS 52 with gas or HERS 55 all-electric.
What triggers a HERS rating in Raynham?
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 Raynham?
Not by code today. Raynham has not adopted the Stretch Code and follows the Massachusetts base energy code, so the Stretch HERS targets do not apply. A HERS rating is still used for ENERGY STAR certification, and it would be required for new homes, larger additions and extensive renovations if Raynham adopts the Stretch Code.
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 Raynham?
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 Raynham?
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 Raynham?
We are a certified RESNET HERS rater serving Raynham and the surrounding area. We provide HERS ratings for new construction, additions, and renovations.
Is a HERS rating required for new homes in Raynham?
Raynham has not adopted the Stretch Code and follows the Massachusetts base energy code, so the Stretch HERS 42/45 limits do not apply. Many builders still get a HERS rating for ENERGY STAR certification or to benchmark the house against Stretch-level performance.
Can I apply for a Raynham building permit online?
Yes. Raynham has offered online permitting since 2020 through a portal linked from the Building Department page. The department asks applicants to call first to confirm which sign-offs their project needs.
Stretch Code HERS Score Requirements by Year
Raynham follows the Massachusetts base energy code, so these targets apply only if the town adopts the Stretch Code. 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.
| Building type | New construction (permits after July 1, 2024) | New construction with embodied carbon credit | Accessory Dwelling Units | Major alterations, additions, or change of use |
|---|---|---|---|---|
| Mixed-Fuel Building | HERS 42 | HERS 45 | HERS 52 | HERS 65 |
| Solar Electric Generation | HERS 42 | HERS 45 | HERS 55 | HERS 70 |
| All-Electric Building | HERS 45 | HERS 48 | HERS 55 | HERS 70 |
| Solar Electric & All-Electric Building | HERS 45 | HERS 48 | HERS 58 | HERS 75 |
Ever wondered why that qualifying figure keeps ratcheting lower with each year that passes? Massachusetts has tightened its HERS requirements year after year — sliding from about 55 down toward 52 and now to roughly 42 for fossil-fuel homes and 45 for all-electric homes in Raynham. Each tightening moves new construction closer to net-zero, and that is precisely why early planning and precise modeling pay off on a Raynham 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.
Mechanical Ventilation Requirements in Raynham
Hitting a low HERS Index in Raynham means building a very airtight, well-insulated home — and a tight home needs controlled mechanical ventilation to stay healthy. The energy code pairs air-sealing with a whole-house ventilation system so fresh air is delivered on purpose rather than through random leaks.
Continuous whole-house ventilation
A whole-house system runs continuously and is sized to ASHRAE 62.2. The minimum airflow follows code equation R403.6: Q = 0.03 × CFA + 7.5 × (Nbr + 1) − 0.052 × Q50 × S × WSF, where CFA is conditioned floor area, Nbr is the number of bedrooms, S is the building-height factor, and WSF is the shielded weather factor for the county. The blower-door result converts with Q50 = (V × 2·ACH50) / 60, using conditioned volume V.
Balanced ERV / HRV
In our cold climate (zone 5A), balanced heat- or energy-recovery ventilation is the practical way to hit a low HERS score. An ERV or HRV supplies fresh air and exhausts stale air while recovering most of the heat between the two streams, so ventilation does not wreck the energy target.
Local exhaust
Kitchens and bathrooms still need local spot exhaust in addition to the whole-house system — vented to the outdoors, not into an attic or crawlspace — to remove moisture and cooking pollutants at the source.
Source: Massachusetts 2025 Stretch & Specialized Codes Technical Guidance (residential ventilation — IRC M1505 / ASHRAE 62.2).
EV-Ready Requirements in Raynham
New homes in Raynham must be wired so an electric-vehicle charger can be added later without opening up finished walls. Under the Massachusetts Stretch Code, “EV-Ready” means the rough electrical infrastructure is in place at the time of construction — here is what that involves.
Dedicated circuit
A 40-amp, 208/240-volt branch circuit is reserved for each dwelling’s parking space, sized to run a Level 2 charger.
Panel capacity
Electrical-panel space and labeled capacity are reserved so a future Level 2 charger can be added without a service upgrade.
Conduit & outlet
A raceway or conduit is run to the parking area so the charger installs quickly when the homeowner is ready.
Source: Massachusetts 2025 Stretch & Specialized Codes Technical Guidance (EV-Ready / Section R404.4).
Mass Save Rebates & Incentives
The figures on this page break down the Mass Save incentives open to Raynham projects. New builds and substantial renovations follow different incentive tracks, and the reward climbs as your HERS score pulls further below the required target — the more efficient your Raynham home, the larger the rebate that comes back your way. Our team runs the energy modeling and manages the paperwork so your project claims everything it is owed.
A HERS rating can unlock Mass Save incentives for eligible projects in Raynham. Incentives are available for both new construction and for renovations and additions. Actual amounts depend on project type, number of units, efficiency level, and program eligibility.
New Construction Incentives (Single-family, 1-4 units)

HERS Ratings in Raynham, Massachusetts
Home Energy Efficiency Consultants provides Raynham with certified HERS ratings, blower door and duct leakage testing, and Massachusetts energy-code compliance for new construction, additions, and major renovations — with same-day preliminary reports.
We rate homes across the Commonwealth from our four offices. Reach the one nearest your Raynham project — Somerville, Framingham, Marlborough, or Everett — or call (617) 501-6788 to schedule a Raynham rating.
Raynham Energy Code Status: What Your Building Permit Requires
Massachusetts municipalities follow one of three energy code tiers. As of June 2026, 242 of 351 cities and towns enforce the Stretch Code — which requires new mixed-fuel homes to reach HERS 42 or lower and all-electric homes HERS 45 or lower under the 2025 amendments — while 60 municipalities enforce the stricter Specialized Code and roughly 49 remain on the base code (IECC 2021 with Massachusetts amendments). Raynham is not on the Specialized Code list, so your project follows either the Stretch Code or the base code depending on Raynham's current adoption status.
We confirm the exact code path with the Raynham building department on every project, then handle the full compliance chain: a preliminary HERS certificate for your permit application (same-day available), plan review, blower door and duct leakage testing, and the final HERS certificate for your certificate of occupancy. Additions over 1,000 sq ft and Level 3 renovations can also trigger HERS requirements. See our Stretch Code compliance service or call (617) 501-6788 for a same-day answer on what Raynham requires.
