REScheck & COMcheck Attleboro MA
Home Energy Efficiency Consultants prepares REScheck (residential) and COMcheck (commercial) compliance documentation for Attleboro projects. When your build does not trigger a full HERS rating, these DOE compliance reports are the fast, affordable path to your permit.
What we deliver
A signed compliance report matched to your plans and ready to upload with your Attleboro building permit application.
Understanding REScheck and COMcheck
Both are free compliance software tools developed by the U.S. Department of Energy (DOE) to demonstrate that a building meets the International Energy Conservation Code (IECC). They document your envelope, and for commercial work your lighting and mechanical systems, so a plan reviewer in Attleboro can confirm compliance quickly.
What is a REScheck?
REScheck is DOE software for residential compliance — detached one- and two-family homes and multifamily buildings three stories or fewer. It runs a UA (insulation and window) trade-off calculation against the IECC, letting extra performance in one assembly offset another so the whole envelope still passes.
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.
Is a REScheck Right for Your Attleboro Project?
REScheck is the simplest path for smaller residential projects in Attleboro 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
- Finished basements, attic conversions, and dormer additions on existing homes
- 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
- Additions, alterations, or renovations to a one- or two-family home
Commercial Work That Needs a COMcheck in Attleboro
COMcheck is required for commercial and larger projects in Attleboro. Reach for a COMcheck when your project involves:
- Restaurant build-outs and retail white-box improvements
- New mechanical (HVAC) or service water heating systems in commercial spaces
- Commercial buildings — offices, retail, restaurants, warehouses, and mixed-use
- Warehouse, industrial, and light-manufacturing conditioned spaces
- High-rise residential buildings of four stories or more

Which Energy Code Report Does a Attleboro Project Need?
Attleboro is not one of the 60 Massachusetts communities on the Specialized (Opt-In) Code, so projects follow the Massachusetts Stretch Code (225 CMR 22.00 and 23.00), which 242 communities have adopted. The state's adoption list shows Attleboro on the Stretch Code since January 1, 2020.
| Your Attleboro 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. Attleboro is in Bristol County, served from our Framingham (68 South St) office.

REScheck & COMcheck for Attleboro Permits
Attleboro's building department spells out the energy paperwork up front. Its information sheets for new homes, additions, and attic or basement conversions all list "Energy Conservation documentation" as part of the application. Which document that is depends on the job. Attleboro has been on the Massachusetts Stretch Code since January 1, 2020, and has not adopted the Specialized (Opt-In) Code.
| Attleboro project | Energy documentation |
|---|---|
| Addition up to 1,000 sq ft and not more than 100% of the existing home, or an attic or basement conversion | REScheck, where the prescriptive path is allowed |
| New single-family home, duplex or townhouse | HERS rating: 42 mixed-fuel or 45 all-electric |
| Larger addition or major renovation | Whole-house HERS rating: 65 mixed-fuel or 70 all-electric |
| Commercial building, addition or fit-out | COMcheck; a commercial building over 20,000 sq ft needs more than COMcheck |
Applications go in online through Attleboro's PermitEyes portal for Building Inspection at 77 Park Street. Contractors and homeowners both apply online; fence permits are the exception and still use a paper packet. Upload the energy report as a PDF with your plans so the reviewer can match the insulation, window and equipment specs.
Transit-oriented housing is changing the area around the MBTA station. A 2024 pipeline included One Wall Street, at more than 130 market-rate units, and a 6.5-acre master development site planned for more than 610 units. Mixed-use buildings like these often need both residential energy documentation and COMcheck for the ground-floor commercial space. HEEC's Framingham office at 68 South St is our closest to Attleboro, and every report is delivered digitally.
REScheck & COMcheck Questions for Attleboro Projects
Do I need a REScheck or a HERS rating in Attleboro?
Under the Massachusetts Stretch Code, new homes need a HERS rating (HERS 42 mixed-fuel or 45 all-electric) or Passive House. 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 renovations. Attleboro has been on the Stretch Code since January 1, 2020.
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 Attleboro?
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.
What does "Energy Conservation documentation" mean on Attleboro's permit checklists?
It is the proof that your project meets the energy code. For a small addition or an attic or basement conversion that is usually a REScheck. For a new home in Attleboro, which is on the Stretch Code, it is a HERS rating of 42 mixed-fuel or 45 all-electric.
Can I apply for an Attleboro building permit online?
Yes. Attleboro requires contractors and homeowners to apply online through PermitEyes, with fence permits as the exception. Upload your REScheck, COMcheck or HERS documentation with the plans.
