REScheck & COMcheck Needham MA - Quick Facts
Local energy code in Needham
- As of July 1, 2024, Needham enforces the Massachusetts Specialized (Opt-In) Energy Code on top of the Stretch Code baseline - IECC Climate Zone 5A.
- The Opt-In code goes further than the Stretch baseline: new fossil-fuel homes must be pre-wired for electrification and include on-site solar where roof space allows.
- New all-electric homes rely on heat pumps for heat and hot water; large fossil-fuel homes over 4,000 sq ft must hit net-zero (HERS 0), and multifamily over 12,000 sq ft must be Passive House.
REScheck & COMcheck in Needham
- REScheck documents the prescriptive residential path for Needham 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 Needham permit application.
Mass Save rebates for Needham (2026)
- 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 Needham MA
Need a REScheck or COMcheck in Needham? We produce permit-ready energy code compliance reports for homes and commercial buildings across Norfolk County, matched precisely to your plans so your project clears plan review the first time.
What we deliver
A stamped, signed compliance report matched to your plans and ready to upload with your Needham 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 Needham can confirm compliance quickly.
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.
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.
Is a REScheck Right for Your Needham Project?
REScheck is the simplest path for smaller residential projects in Needham 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
- Permit applications needing residential envelope documentation on the prescriptive or UA trade-off path
- Multifamily buildings of three stories or fewer
- Window and insulation upgrades that must be documented for a building permit
- Finished basements, attic conversions, and dormer additions on existing homes
Commercial Work That Needs a COMcheck in Needham
COMcheck is required for commercial and larger projects in Needham. Reach for a COMcheck when your project involves:
- Medical, dental, and professional office construction
- Commercial buildings — offices, retail, restaurants, warehouses, and mixed-use
- Envelope work on commercial structures requiring IECC or ASHRAE 90.1 compliance
- Tenant fit-outs and interior or exterior lighting alterations
- Warehouse, industrial, and light-manufacturing conditioned spaces

Needham Specialized Energy Code — HERS Index Targets
Needham enforces the Massachusetts Specialized (Opt-In) Energy Code. The required HERS score depends on fuel type and project scope — a lower index is stricter.
| 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 Needham project up front so you know the exact target and the fastest path to hit it — call (617) 501-6788.
