REScheck & COMcheck 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.
REScheck & COMcheck in Beverly
- REScheck documents the prescriptive residential path for Beverly additions, alterations and renovations (from $300); new-construction performance projects use a full HERS energy model instead.
- Commercial projects use COMcheck for the prescriptive path (from $600); larger new commercial buildings need third-party performance certification under the Stretch Code.
- 24-48 hour turnaround - documentation ready to upload with your Beverly permit application.
Mass Save rebates for Beverly (2026)
- All-electric renovations and additions can earn Mass Save incentives up to $20,000 (Level 1) or $30,000 (Level 2) for a single-family home, verified by a RESNET-certified HERS rater.

REScheck vs. COMcheck: What’s the Difference?
REScheck and COMcheck are DOE-developed programs that show a building meets the IECC energy code. Which one your Beverly project needs depends on whether the work is residential or commercial — here is how they differ.
What is a COMcheck?
COMcheck is DOE software for commercial buildings and high-rise residential (four stories or more). It checks the building envelope, interior and exterior lighting, and mechanical systems against the IECC or ASHRAE Standard 90.1, and can trade off components across the design.
What is a REScheck?
REScheck is the DOE’s residential compliance tool. It covers one- and two-family dwellings and low-rise multifamily (three stories or fewer), using a UA trade-off so a stronger wall or roof can make up for a weaker window while the overall envelope still meets the IECC.
Is a REScheck Right for Your Beverly Project?
REScheck is the simplest path for smaller residential projects in Beverly that do not need a HERS rating. It is typically the right tool for:
- New residential construction or an addition of 1,000 sq ft or less that does not require a HERS rating
- Multifamily buildings of three stories or fewer
- Projects where insulation and window trade-offs are enough to demonstrate compliance
- Permit applications needing residential envelope documentation on the prescriptive or UA trade-off path
- Finished basements, attic conversions, and dormer additions on existing homes
When Do You Need a COMcheck in Beverly?
COMcheck is required for commercial and larger projects in Beverly. Reach for a COMcheck when your project involves:
- Commercial buildings — offices, retail, restaurants, warehouses, and mixed-use
- Tenant fit-outs and interior or exterior lighting alterations
- Envelope work on commercial structures requiring IECC or ASHRAE 90.1 compliance
- High-rise residential buildings of four stories or more
- Restaurant build-outs and retail white-box improvements

Which Energy Code Report Does a Beverly Project Need?
Beverly has adopted the Massachusetts Specialized Code (the municipal opt-in code, 225 CMR 22.00 Appendix RC for homes and 225 CMR 23.00 Appendix CC for commercial and multifamily). New homes must be built to the net-zero-ready Specialized paths, new homes over 4,000 sq ft must use the all-electric or zero-energy path, and new multifamily buildings over 12,000 sq ft must be Passive House certified.
| Your Beverly project | What the energy code paperwork usually is |
|---|---|
| New single-family home or low-rise residential building | A HERS rating or Passive House certification on a Specialized Code path. REScheck is not accepted for new homes. |
| Residential addition of 1,000 sq ft or less (and not over 100% of the existing home) | REScheck (REScheck-Web, 2023 Massachusetts Stretch Code) or the prescriptive tables |
| Residential addition over 1,000 sq ft or over 100% of the existing home | A HERS rating of the whole house (HERS 65 or lower mixed-fuel, 70 or lower all-electric) |
| Basement or attic conversion with no change to footprint or roofline | No HERS rating required; REScheck or prescriptive documentation |
| Residential renovation or alteration | Prescriptive alteration rules; REScheck can document the envelope. Large "extensive" alterations over 1,000 sq ft may need a HERS rating. |
| New commercial building up to 20,000 sq ft | COMcheck: Envelope, Lighting and Mechanical certificates plus the Plan Review Inspection Checklist |
| New commercial building over 20,000 sq ft | COMcheck Lighting and Mechanical, with the envelope shown by backstop and thermal-bridge calculations, on a performance path (Targeted Performance/TEDI or ASHRAE 90.1 Appendix G) or Passive House |
| Commercial addition, alteration, or lighting/HVAC change | COMcheck for the altered systems |
| Multifamily building over 12,000 sq ft | Passive House certification (Phius or PHI) |
Based on 225 CMR 22.00 and 23.00 (Massachusetts energy code, 2025 edition). Building departments make the final call, so we confirm the path for your project before we start. Beverly is in Essex County, served from our Everett (371 Main St) office.

REScheck & COMcheck for Beverly Permits
Beverly is one of the few cities that has moved past the Stretch Code. The state's adoption list shows Beverly on the Stretch Code from January 1, 2012 and on the Specialized (Opt-In) Code effective January 1, 2026, so any project permitted now falls under the stricter rules.
For a Beverly homeowner, the practical question is whether REScheck is still allowed. It is, for the right job. REScheck covers small residential additions and alterations where the prescriptive path is allowed, meaning an addition up to 1,000 sq ft that is not more than 100% of the existing home. A brand-new house needs a HERS rating (42 mixed-fuel, which under the Specialized (Opt-In) Code also brings solar and electric-readiness requirements, or 45 all-electric) or Passive House. A larger addition or major renovation needs a whole-house HERS rating of 65 mixed-fuel or 70 all-electric.
On the commercial side, COMcheck still documents the envelope, lighting and mechanical systems for most commercial projects. A commercial building over 20,000 sq ft needs more than COMcheck under both the Stretch Code and the Specialized (Opt-In) Code, and new multifamily over 12,000 sq ft has to meet Passive House. That matters around Beverly Depot, where Holmes Beverly Phase II is adding 52 mixed-income homes, and along Rantoul Street, where NEI began a six-story mixed-use building at 112 Rantoul with 67 apartments over retail.
Beverly no longer accepts paper building permit applications. Building, electrical, gas, plumbing and mechanical permits are filed through the city's OpenGov online permit center, where you upload plans and supporting documents and track inspections. We send your energy code report as a PDF ready to attach. Beverly projects are handled from our Everett office at 371 Main St.
REScheck & COMcheck Questions for Beverly Projects
Do I need a REScheck or a HERS rating in Beverly?
For a new home in Beverly, you need a HERS rating or Passive House, because Beverly is on the Specialized Code. REScheck is used for smaller additions (1,000 sq ft or less and not over 100% of the existing home), basement and attic conversions, and renovations.
When is a COMcheck required in Massachusetts?
A COMcheck documents commercial energy code compliance for new commercial buildings up to 20,000 sq ft (envelope, lighting and mechanical), for lighting and mechanical on larger buildings, and for commercial additions and alterations such as fit-outs, lighting changes and HVAC replacements. Massachusetts commercial code is based on the 2021 IECC with state amendments in 225 CMR 23.00.
What does a COMcheck include?
The COMcheck Envelope Compliance Certificate, the Interior and Exterior Lighting Compliance Certificates, the Mechanical Compliance Certificate, and the Plan Review Inspection Checklist. Massachusetts 225 CMR 23.00 Section C103.2 lists these as the construction-document requirements for buildings up to 20,000 sq ft.
What does a REScheck include?
A REScheck compares your home's envelope (insulation R-values and window U-values) to the code using a total UA trade-off, so stronger performance in one assembly can offset another. The report includes the compliance certificate and inspection checklist. Mandatory items such as air sealing and duct sealing still apply.
What size addition needs a HERS rating instead of REScheck?
In Massachusetts, a residential addition over 1,000 sq ft, or over 100% of the existing conditioned floor area, needs a HERS rating of the whole house (225 CMR 22.00 R502.1.1). Converting an existing basement or attic without changing the footprint or roofline does not.
What information do you need to prepare a REScheck or COMcheck?
Plans with wall, roof and floor sections, insulation types and R-values, the window and door schedule with U-factors and SHGC, and for commercial work the lighting fixture schedule with wattages, lighting controls, and HVAC and water heating equipment schedules.
Which software version is used in Massachusetts?
REScheck-Web with the 2023 Massachusetts Stretch Code option for residential, and COMcheck-Web set to the 2021 IECC (or ASHRAE 90.1-2019) for commercial, matching the code Massachusetts enforces.
How much does a REScheck or COMcheck cost in Beverly?
REScheck reports start at $300 and COMcheck reports start at $600. The final price depends on the size of the project and how many assemblies and systems need to be entered. Send your plans for an exact quote.
Can I still use REScheck in Beverly now that it is on the Specialized Code?
Yes, for small residential additions and alterations. Beverly's Specialized (Opt-In) Code took effect January 1, 2026, but an addition up to 1,000 sq ft that is not more than 100% of the existing home can still use REScheck where the prescriptive path is allowed. New homes need a HERS rating or Passive House.
How are building permits filed in Beverly?
Beverly no longer accepts paper building permit applications. Building, electrical, gas, plumbing and mechanical permits are filed through the city's OpenGov online permit center, where applicants upload plans and supporting documents such as a REScheck, COMcheck or HERS report.

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 type | Mixed-fuel | Mixed-fuel + solar | All-electric | All-electric + solar |
|---|---|---|---|---|
| New construction | HERS 42 | 42 | 45 | 45 |
| New construction — embodied-carbon credit | 45 | 45 | 48 | 48 |
| Accessory dwelling unit (ADU) | 52 | 55 | 55 | 58 |
| Major alteration / renovation / change of use | 65 | 70 | 70 | 75 |
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.
