REScheck & COMcheck Concord MA - Quick Facts
Local energy code in Concord
- Concord adopted the Massachusetts Specialized (Opt-In) Energy Code effective January 1, 2024; the Stretch Code applies as the baseline. 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.
- Concord 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 Concord
- REScheck documents the prescriptive residential path for Concord 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 Concord permit application.
2026 Mass Save incentives in Concord
- 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 Concord MA
Home Energy Efficiency Consultants prepares REScheck (residential) and COMcheck (commercial) compliance documentation for Concord 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 stamped, signed compliance report matched to your plans and ready to upload with your Concord building permit application.
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 Middlesex County project demonstrate that its envelope (and, for commercial, lighting and mechanical) meets the IECC.
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.
REScheck Projects in Concord
REScheck is the simplest path for smaller residential projects in Concord 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
- Detached accessory structures with conditioned space
- Projects where insulation and window trade-offs are enough to demonstrate compliance
- Finished basements, attic conversions, and dormer additions on existing homes
- Multifamily buildings of three stories or fewer
When Do You Need a COMcheck in Concord?
COMcheck is required for commercial and larger projects in Concord. Reach for a COMcheck when your project involves:
- High-rise residential buildings of four stories or more
- Commercial buildings — offices, retail, restaurants, warehouses, and mixed-use
- Tenant fit-outs and interior or exterior lighting alterations
- New mechanical (HVAC) or service water heating systems in commercial spaces
- Medical, dental, and professional office construction

Concord Specialized Energy Code — HERS Index Targets
Concord 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 Concord 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 Concord project up front so you know the exact target and the fastest path to hit it — call (617) 501-6788.
