REScheck & COMcheck Clarksburg MA
From small additions to commercial fit-outs in Clarksburg, we deliver the REScheck and COMcheck reports your Berkshire County building department requires — accurate, signed, and turned around quickly.
What we deliver
A signed compliance report matched to your plans and ready to upload with your Clarksburg building permit application.
Understanding REScheck and COMcheck
These are the two standard software tools plan reviewers accept for energy code compliance. Developed by the DOE, they let a Berkshire County project demonstrate that its envelope (and, for commercial, lighting and mechanical) meets the IECC.
What is a COMcheck?
For commercial and four-plus-story residential buildings, COMcheck is required. It documents envelope, lighting, and mechanical compliance against the IECC or ASHRAE Standard 90.1 and produces the certificates a commercial plan reviewer expects.
What is a REScheck?
For homes, REScheck is the go-to. This DOE program checks residential envelopes — detached houses and multifamily up to three stories — and allows insulation and fenestration trade-offs to show prescriptive or component-based IECC compliance.
When Do You Need a REScheck in Clarksburg?
REScheck is the simplest path for smaller residential projects in Clarksburg that do not need a HERS rating. It is typically the right tool for:
- Residential additions of 1,000 sq ft or less that are not more than 100% of the existing home
- Basement and attic conversions that do not change the footprint or roofline
- Renovations and alterations to existing homes that need envelope documentation
- Detached accessory structures with conditioned space, where Clarksburg's building department accepts REScheck
- New homes only in base-code towns; Stretch and Specialized (Opt-In) Code towns require a HERS rating or Passive House for new homes
When Do You Need a COMcheck in Clarksburg?
COMcheck is required for commercial and larger projects in Clarksburg. Reach for a COMcheck when your project involves:
- 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
- New mechanical (HVAC) or service water heating systems in commercial spaces

Which Energy Code Report Does a Clarksburg Project Need?
Clarksburg adopted the Massachusetts Stretch Code (225 CMR 22.00 and 23.00) effective January 1, 2017, according to the state's adoption list, and has not adopted the Specialized (Opt-In) Code. New homes and larger renovations in Clarksburg need a HERS rating; small additions and alterations can use REScheck.
| Your Clarksburg project | What the energy code paperwork usually is |
|---|---|
| New single-family home or low-rise residential building | In Stretch Code towns, a HERS rating (maximum HERS 42 mixed-fuel, 45 all-electric) or Passive House. REScheck is not accepted for new homes under the Stretch Code. |
| 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 or a HERS/performance path |
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. Clarksburg is in Berkshire County, served from our Marlborough (272 Lincoln St) office.

REScheck & COMcheck for Clarksburg Permits
Clarksburg adopted the Massachusetts Stretch Code effective January 1, 2017, and it remains on the Stretch Code on the state's current adoption list. That decides which energy report a Clarksburg project needs.
Filing with the Clarksburg Building Department
The town's building permit packet describes paper applications delivered to Clarksburg Town Hall Monday through Thursday, reviewed by the Building Commissioner. Its checklist asks for energy conservation documents, and for heated or cooled additions, garages and gut renovations it names a REScheck ("ResCheck") as an accepted document. Because the forms cite different IECC editions, we confirm the current requirement with the department before we submit.
Which report fits your Clarksburg project
- REScheck: small residential additions and alterations where the prescriptive path is allowed, such as an addition of up to 1,000 sq ft that is not more than 100% of the existing home. Basement and attic conversions that do not change the footprint or roofline are usually handled the same way.
- HERS rating: new homes in Clarksburg need a HERS rating instead of REScheck, with a maximum of HERS 42 for mixed-fuel or 45 for all-electric. Larger additions and renovations need a whole-house rating of HERS 65 (mixed-fuel) or 70 (all-electric).
- COMcheck: commercial buildings and fit-outs. Under the Stretch Code, a new commercial building over 20,000 sq ft needs more than a COMcheck, typically a performance path or Passive House.
Clarksburg projects are handled from our Marlborough office at 272 Lincoln St C1. We work from your drawings and send a signed PDF that you can attach to the paper application.
REScheck & COMcheck Questions for Clarksburg Projects
Do I need a REScheck or a HERS rating in Clarksburg?
Clarksburg is a Stretch Code town (effective January 1, 2017), so new homes need a HERS rating (HERS 42 mixed-fuel or 45 all-electric) or Passive House, and larger renovations need HERS 65 or 70. REScheck is used for additions of 1,000 sq ft or less that are not over 100% of the existing home, basement and attic conversions, and smaller renovations.
Does the Clarksburg building permit checklist ask for a REScheck?
Yes. The Town of Clarksburg building permit checklist asks for energy conservation compliance documents, and for heated or cooled additions, garages and alterations where framing is exposed it lists a REScheck as an accepted document. New homes need a HERS rating because Clarksburg is a Stretch Code town.
How do I submit a building permit in Clarksburg?
The town permit packet says applications are delivered to Clarksburg Town Hall, Monday through Thursday during business hours, for review by the Building Commissioner. We prepare your REScheck, COMcheck or HERS documents as PDFs you can print and include with the application.
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 Clarksburg?
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.
