Local energy code in West Tisbury
- As of January 1, 2025, West Tisbury 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.

What Is a REScheck and What Is a COMcheck?
REScheck and COMcheck are DOE-developed programs that show a building meets the IECC energy code. Which one your West Tisbury project needs depends on whether the work is residential or commercial — here is how they differ.
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?
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 West Tisbury Project?
REScheck is the simplest path for smaller residential projects in West Tisbury 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
- Finished basements, attic conversions, and dormer additions on existing homes
- Multifamily buildings of three stories or fewer
- Additions, alterations, or renovations to a one- or two-family home
When Do You Need a COMcheck in West Tisbury?
COMcheck is required for commercial and larger projects in West Tisbury. Reach for a COMcheck when your project involves:
- Tenant fit-outs and interior or exterior lighting alterations
- Commercial buildings — offices, retail, restaurants, warehouses, and mixed-use
- High-rise residential buildings of four stories or more
- Envelope work on commercial structures requiring IECC or ASHRAE 90.1 compliance
- Restaurant build-outs and retail white-box improvements

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