REScheck & COMcheck Acton MA - Quick Facts
Local energy code in Acton
- Acton has been an Opt-In (Specialized Code) community since January 1, 2024, layering electrification requirements on the Stretch Code; it sits in IECC Climate Zone 5A.
- Beyond the Stretch baseline, new mixed-fuel homes must be pre-wired for future electrification and add on-site solar where there is significant unshaded roof space.
- All-electric new homes must use heat pumps for space heating and hot water; fossil-fuel homes over 4,000 sq ft must reach net-zero (HERS 0), and new multifamily over 12,000 sq ft must meet Passive House.
- Acton also participates in the Massachusetts Municipal Fossil Fuel-Free Building Demonstration Program - new construction and major renovations must be built fossil-fuel-free (all-electric), a step beyond the Specialized Code.
REScheck & COMcheck in Acton
- REScheck documents the prescriptive residential path for Acton 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 Acton permit application.
What you can get back: 2026 Mass Save
- 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 & COMcheck Acton MA
Fast, accurate REScheck and COMcheck energy code compliance reports for residential and commercial projects in Acton, Massachusetts. We prepare the documentation your building department needs to issue a permit — without the cost of a full performance-path energy rating when your project does not require one.
What we deliver
A stamped, signed compliance report matched to your plans and ready to upload with your Acton building permit application.
REScheck vs. COMcheck: What’s the Difference?
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 Acton 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 Acton
REScheck is the simplest path for smaller residential projects in Acton that do not trigger a full performance-path energy rating. It is typically the right tool when your project is:
- New residential construction or an addition under 1,200 square feet that does not require a HERS rating
- Window and insulation upgrades that must be documented for a building permit
- Multifamily buildings of three stories or fewer
- Finished basements, attic conversions, and dormer additions on existing homes
- Projects where insulation and window trade-offs are enough to demonstrate compliance
Commercial Work That Needs a COMcheck in Acton
COMcheck is required for commercial and larger projects in Acton. Reach for a COMcheck when your project involves:
- Medical, dental, and professional office construction
- New mechanical (HVAC) or service water heating systems in commercial spaces
- High-rise residential buildings of four stories or more
- Commercial buildings — offices, retail, restaurants, warehouses, and mixed-use
- Warehouse, industrial, and light-manufacturing conditioned spaces

Acton Specialized Energy Code — HERS Index Targets
Acton enforces the Massachusetts Specialized (Opt-In) Energy Code. The required HERS score depends on fuel type and project scope — a lower index is stricter. As a fossil-fuel-free community, new construction in Acton must be built all-electric, so the all-electric columns apply.
| 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 Acton project up front so you know the exact target and the fastest path to hit it — call (617) 501-6788.
