REScheck & COMcheck Taunton MA
Need a REScheck or COMcheck in Taunton? We produce permit-ready energy code compliance reports for homes and commercial buildings across Bristol County, matched precisely to your plans so your project clears plan review the first time.
What we deliver
A signed compliance report matched to your plans and ready to upload with your Taunton building permit application.
What Is a REScheck and What Is a 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 Taunton can confirm compliance quickly.
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.
REScheck Projects in Taunton
REScheck is the simplest path for smaller residential projects in Taunton 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
- Detached accessory structures with conditioned space
- Window and insulation upgrades that must be documented for a building permit
When Do You Need a COMcheck in Taunton?
COMcheck is required for commercial and larger projects in Taunton. Reach for a COMcheck when your project involves:
- Envelope work on commercial structures requiring IECC or ASHRAE 90.1 compliance
- Commercial buildings — offices, retail, restaurants, warehouses, and mixed-use
- High-rise residential buildings of four stories or more
- Medical, dental, and professional office construction
- Warehouse, industrial, and light-manufacturing conditioned spaces

Which Energy Code Report Does a Taunton Project Need?
Taunton is on the Massachusetts base energy code (225 CMR 22.00 and 23.00). The state's adoption list shows that Taunton has not adopted the Stretch Code, which 242 communities use, or the Specialized (Opt-In) Code, which 60 communities use.
| Your Taunton project | What the energy code paperwork usually is |
|---|---|
| New single-family home or low-rise residential building | Under Taunton's base code, the prescriptive path (documented with REScheck) or a performance path, usually a HERS rating. The HERS 42 / 45 requirement applies only in Stretch and Specialized Code towns. |
| Residential addition of 1,000 sq ft or less (and not over 100% of the existing home) | REScheck (REScheck-Web) or the prescriptive tables |
| Residential addition over 1,000 sq ft or over 100% of the existing home | In Stretch and Specialized towns, a whole-house HERS rating (65 mixed-fuel, 70 all-electric). Under Taunton's base code we confirm the path with the Building Department. |
| 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. The added performance-path, backstop and thermal-bridge requirements apply in Stretch and Specialized towns, not under Taunton's base code. |
| 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 in Stretch and Specialized towns; under Taunton's base code, we confirm the path with the Building Department |
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. Taunton is in Bristol County, served from our Framingham (68 South St) office.

REScheck & COMcheck for Taunton Permits
Taunton is different from most cities around it. On the state's adoption list, Taunton is on the base energy code. It has not adopted the Stretch Code or the Specialized (Opt-In) Code. That gives Taunton builders more options than their neighbors.
New homes in Taunton: under the base code, builders can use the prescriptive method (which REScheck documents) or a performance method, usually a HERS rating. The HERS 42 mixed-fuel / 45 all-electric requirement applies only in Stretch and Specialized towns.
Additions and alterations: REScheck is the usual report for a residential addition up to 1,000 sq ft and not more than 100% of the existing home, where the prescriptive path is allowed. The whole-house HERS 65 / 70 rule for larger renovations is a Stretch and Specialized Code requirement.
Commercial work: COMcheck documents the envelope, lighting and mechanical systems. The extra steps for commercial buildings over 20,000 sq ft (performance modeling, envelope backstop and thermal-bridge calculations) belong to the Stretch and Specialized codes, not Taunton's base code.
The Taunton Building Department at 141 Oak Street takes building permits online through PermitEyes, which replaced the city's old Accela portal. You can also apply in person, and walk-in permits are paid by check or money order only. The department's quick links include an "Energy Codes" link to the DOE REScheck page.
Big projects are going up, too. Greystar's 390-apartment modular redevelopment of Whittenton Mills at 437 Whittenton St broke ground in 2026. Our Framingham office at 68 South St is the closest HEEC office to Taunton.
REScheck & COMcheck Questions for Taunton Projects
Do I need a REScheck or a HERS rating in Taunton?
Taunton is on the base energy code, so a new home can use the prescriptive path (documented with REScheck) or a performance path such as a HERS rating. REScheck is also 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.
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 Stretch and Specialized Code towns, 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). Taunton is on the base code, so we confirm the path with the Building Department. 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 set to the code Taunton enforces (the base energy code) 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 Taunton?
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.
Is Taunton on the Stretch Code?
No. The state's adoption list shows Taunton on the base energy code. It has not adopted the Stretch Code or the Specialized (Opt-In) Code, so new homes can use the prescriptive path (REScheck) or a performance path such as a HERS rating.
How do I file a building permit in Taunton?
Taunton building permits are filed online through PermitEyes or in person at the Building Department, 141 Oak Street. Walk-in permits are paid by check or money order.
