Quick Answers

Do I need a HERS rating in Beverly, 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 Beverly, 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 Beverly project.

How much does a HERS rating cost in Beverly, 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 Beverly project.

We offer same-day scheduling and deliver reports in 24-48 hours. Home Energy Efficiency Consultants has completed 15,000+ HERS ratings statewide and holds a 5.0-star rating from 136 Google reviews.

HERS Rating Beverly MA - Quick Facts

Local energy code in Beverly

  • As of January 1, 2026, Beverly enforces the Massachusetts Specialized (Opt-In) Energy Code on top of the Stretch Code baseline - IECC Climate Zone 5A.
  • The Opt-In code goes further than the Stretch baseline: new fossil-fuel homes must be pre-wired for electrification and include on-site solar where roof space allows.
  • New all-electric homes rely on heat pumps for heat and hot water; large fossil-fuel homes over 4,000 sq ft must hit net-zero (HERS 0), and multifamily over 12,000 sq ft must be Passive House.

What the code requires in Beverly

  • A HERS rating is required in Beverly 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 Beverly 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 Beverly (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.

📦

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 Beverly

From the first permit set you submit to the final certificate we hand back, here is exactly how we shepherd a Beverly project through HERS verification.

1️⃣

Plan Review & Preliminary Report

We review your blueprints and produce the preliminary energy report your building permit requires before construction begins.

2️⃣

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.

3️⃣

Mid-Point Inspection

We inspect during construction to make sure insulation is installed correctly and to the code requirements of your HERS report.

4️⃣

Final Testing

Blower-door testing, duct testing, and ERV balancing. ERV balancing is vital — done wrong it can cause pressure issues throughout your home.

5️⃣

Final Certificate

We send over the final certificate to close out your building permit and apply for your Mass Save rebates.

Beverly and the Massachusetts Specialized (Opt-In) Code

Situated in Essex County within Climate Zone 5A, Beverly is bound by the Specialized (Opt-In) Code — the toughest energy standard the Commonwealth enforces, which weaves electrification-readiness right into its baseline efficiency rules.

Solar-Ready (RB102)

A new Beverly home is required to keep clear roof area and pre-run conduit, so panels can be mounted later on without a disruptive retrofit.

EV-Ready (RB103)

Spare panel capacity and a dedicated circuit are readied ahead of time, keeping a Level 2 charger install in a Beverly garage both quick and low-cost.

Talk directly with the owner

Dominic Zammuto, the owner and a Mass Save®-listed HERS rater, personally directs every Beverly rating — you speak with the expert, not a call center. Ask him anything about your project or the incentives on the table.

What the HERS Index Means for Beverly Homes

100 is the starting line

The reference home clocks in at 100, and every Beverly home we rate is engineered to end up well beneath that figure.

0 equals net-zero

A zero on the index tells you a Beverly home makes as much energy as it burns — the highest point of efficient design.

About 1% per point

Knock off a single point and you cut about one percent from energy use — real dollars returned to a Beverly owner’s pocket.

How We Confirm Performance on a Beverly Rating

  • ✅ Energy modeling — we develop a performance model of the Beverly home before construction to forecast its energy use room by room.
  • ✅ Blower-door testing — a calibrated fan shows exactly how airtight the finished Beverly home genuinely is.
  • ✅ Duct-leakage testing — we measure the conditioned air lost through the ductwork so none of it is wasted.

Connecting HERS and the Stretch Code in Beverly

  • ✅ Beverly draws on the IECC 2021 model code and layers the Commonwealth’s stricter energy goals on top.
  • ✅ The HERS score you have to reach hinges on fuel type — all-electric and mixed-fuel homes carry separate targets.
  • ✅ We tie your rating into Mass Save incentives and the official Mass.gov stretch code requirements.

Building and Permitting in Beverly

Beverly moved from the Stretch Code to the Specialized (Opt-In) Code on January 1, 2026, after following the Stretch Code since January 1, 2012, according to the state's energy code adoption list. If your project was designed under the old rules and is being permitted now, confirm which code applies before you finalize drawings.

What the Specialized (Opt-In) Code means for HERS

The HERS targets carry over from the Stretch Code. New homes need a HERS rating of 42 if mixed-fuel or 45 if all-electric. Renovations and additions that add more than 1,000 square feet, or more than 100% of the existing conditioned floor area, need HERS 65 (mixed-fuel) or 70 (all-electric). Accessory dwelling units need HERS 52 (mixed-fuel) or 55 (all-electric).

The difference is what sits on top of those numbers. In the state's words, the Specialized Code includes additional requirements that form an appendix to each chapter of the Stretch Code. Review those appendix requirements with your designer and rater before drawings are final, and settle the fuel choice early, since mixed-fuel and all-electric homes carry different HERS targets.

Permitting in Beverly

Permits are handled by the Municipal Inspections / Building Department, which city documents list at 191 Cabot Street. Beverly has filed building, electrical, gas, plumbing and mechanical permits online since 2016, and in 2023 the city moved its permitting and licensing to OpenGov, which also lets applicants check permit and inspection status. Plan to upload the design-stage HERS report with the building application and the final certificate before occupancy.

The state's electric franchise list shows Beverly served by Massachusetts Electric Company rather than a municipal light plant, so Mass Save's residential new construction program, sponsored by the investor-owned utilities, is generally the relevant incentive path.

HEEC serves Beverly from our Everett office at 371 Main St. We can model mixed-fuel and all-electric options side by side so you can see how each performs against the Specialized (Opt-In) Code before you commit.

FAQ About HERS Rating Beverly MA

Common questions about HERS ratings in Beverly, 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 Beverly cost?

A HERS rating in Beverly 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 Beverly?

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 Beverly?

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 Beverly?

Beverly has adopted the Specialized (Opt-In) Code, so 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 Beverly?

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 Beverly?

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 Beverly?

We are a certified RESNET HERS rater serving Beverly and the surrounding area. We provide HERS ratings for new construction, additions, and renovations.

My Beverly project was designed before 2026. Does the Specialized (Opt-In) Code apply?

Beverly's Specialized (Opt-In) Code took effect January 1, 2026. Before that, the city followed the Stretch Code. Which code governs your project generally depends on when the permit application is filed, so confirm with the Municipal Inspections / Building Department and have your HERS rater check the design against the current requirements, including the Specialized Code appendix requirements.

How do I submit a building permit in Beverly?

Beverly accepts building, electrical, gas, plumbing and mechanical permits online, and since 2023 the city has used OpenGov for permitting and licensing, where you can also track permit and inspection status. The Municipal Inspections / Building Department is listed at 191 Cabot Street. Include the design-stage HERS report for any new home, ADU or large addition.

HERS Score Requirements in Beverly 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.

Wondering why the ceiling keeps coming down? The Commonwealth has tightened its HERS requirements again and again — moving from about 55 toward 52 and now to roughly 42 for fossil-fuel homes and 45 for all-electric homes in Beverly. Every step brings new construction nearer to net-zero, which is exactly why planning early and modeling with care pay off on a Beverly 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 Beverly

Hitting a low HERS Index in Beverly 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.

EV-Ready Requirements in Beverly

New homes in Beverly 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.

Mass Save Rebates & Incentives

The charts on this page lay out the Mass Save incentives open to Beverly projects. New builds and major renovations move along separate incentive tracks, and the reward increases as your HERS score sits further below the required target — the more efficient the Beverly home, the bigger the rebate. Our team handles the energy modeling and manages the paperwork so your project claims everything it is entitled to.

A HERS rating can unlock Mass Save incentives for eligible projects in Beverly. 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.

Beverly Specialized Energy Code — HERS Index Targets

Beverly enforces the Massachusetts Specialized (Opt-In) Energy Code. The required HERS score depends on fuel type and project scope — a lower index is stricter.

Project typeMixed-fuelMixed-fuel + solarAll-electricAll-electric + solar
New constructionHERS 42424545
New construction — embodied-carbon credit45454848
Accessory dwelling unit (ADU)52555558
Major alteration / renovation / change of use65707075

A HERS rating is triggered by new construction, additions over 1,000 sq ft (or more than 100% of the existing conditioned area), and Level 3 alterations over 1,000 sq ft affecting more than 50% of the home. New homes must also pass a blower-door test at 3.0 ACH50 and include electrification-ready wiring for heat pumps, EV charging, and solar. We model your Beverly project up front so you know the exact target and the fastest path to hit it — call (617) 501-6788.

More Massachusetts Towns We Serve

Certified HERS ratings, blower door testing and energy code compliance across all 351 Massachusetts cities and towns.

Beverly Enforces the Massachusetts Specialized Code

Beverly is one of just 60 Massachusetts municipalities (as of June 2026) that have adopted the Specialized opt-in energy code — the state’s most demanding standard, covering about a third of Massachusetts residents. For new homes in Beverly this means the full HERS pathway — HERS 42 for mixed-fuel homes, 45 for all-electric (48 with the embodied carbon credit) — plus electrification-ready wiring requirements that go beyond the standard Stretch Code used in most of the state.

Practical impact for Beverly projects: plan for a blower door result of 3.0 ACH50 or better, balanced ERV/HRV ventilation, and either all-electric mechanicals or wiring sized for future electrification. Our raters work in Beverly regularly — see the full inspection sequence or call (617) 501-6788 for a same-day preliminary HERS report.
