What we deliver

REScheck vs. COMcheck: What’s the Difference?
These are the two standard software tools plan reviewers accept for energy code compliance. Developed by the DOE, they let a Essex County project demonstrate that its envelope (and, for commercial, lighting and mechanical) meets the IECC.
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.
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.
REScheck Projects in Amesbury
REScheck is the simplest path for smaller residential projects in Amesbury 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
- Additions, alterations, or renovations to a one- or two-family home
- Window and insulation upgrades that must be documented for a building permit
- Permit applications needing residential envelope documentation on the prescriptive or UA trade-off path
When Do You Need a COMcheck in Amesbury?
COMcheck is required for commercial and larger projects in Amesbury. Reach for a COMcheck when your project involves:
- High-rise residential buildings of four stories or more
- Tenant fit-outs and interior or exterior lighting alterations
- Restaurant build-outs and retail white-box improvements
- Warehouse, industrial, and light-manufacturing conditioned spaces
- Commercial buildings — offices, retail, restaurants, warehouses, and mixed-use

Which Energy Code Report Does a Amesbury Project Need?
Amesbury is not one of the 60 Massachusetts communities on the Specialized Code, so projects follow the Massachusetts Stretch Code (225 CMR 22.00 and 23.00), which 242 communities have adopted. Amesbury adopted the Stretch Code effective January 1, 2014, and it has not adopted the Specialized (Opt-In) Code.
| Your Amesbury 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. Amesbury is in Essex County, served from our Everett (371 Main St) office.

REScheck & COMcheck for Amesbury Permits
Amesbury adopted the Stretch Code effective January 1, 2014, and it has not adopted the Specialized (Opt-In) Code. Permits are handled by Inspectional Services at 39 S Hunt Road. The city moved all residential and commercial permit applications to OpenGov, and paper applications are no longer accepted, so your energy code report needs to be a clean digital file.
Here is how the three common documents line up for an Amesbury project.
REScheck. Used for a small residential addition or alteration where the prescriptive path is allowed. The addition must be up to 1,000 sq ft and not more than 100% of the existing home. A kitchen bump-out or a new primary suite is a typical fit.
HERS rating. Required for new homes and larger renovations under the Stretch Code. New homes need HERS 42 mixed-fuel or HERS 45 all-electric. Larger additions and major renovations need HERS 65 mixed-fuel or HERS 70 all-electric.
COMcheck. Covers envelope, lighting and mechanical compliance for commercial buildings. Commercial buildings over 20,000 sq ft need more than COMcheck under the Stretch Code.
Adaptive reuse is part of the picture in Amesbury. In 2025 the city proposed redeveloping the former Amesbury Elementary School at 24 South Hampton Road with up to 37 housing units. Converting a school into apartments brings its own energy code questions, and it helps to sort them out before plans are final.
HEEC's Everett office at 371 Main St is the closest to Amesbury and the Merrimack Valley. Send your drawings and we will tell you which report Inspectional Services will expect, then deliver it ready to upload in OpenGov.
REScheck & COMcheck Questions for Amesbury Projects
Do I need a REScheck or a HERS rating in Amesbury?
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. We confirm Amesbury's code status before we start.
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 Amesbury?
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 submit a paper building permit in Amesbury?
No. Amesbury moved all residential and commercial permit applications to OpenGov and no longer accepts paper applications. We deliver REScheck, COMcheck and HERS reports as PDFs you can attach to your OpenGov application for Inspectional Services.
Does a new home in Amesbury need a HERS rating?
Yes. Amesbury has used the Stretch Code since January 1, 2014, so a new home needs a HERS rating of 42 mixed-fuel or 45 all-electric. A REScheck is only for small additions and alterations where the prescriptive path is allowed.
