REScheck & COMcheck Lakeville MA
From small additions to commercial fit-outs in Lakeville, we deliver the REScheck and COMcheck reports your Plymouth County building department requires — accurate, signed, and turned around quickly.
What we deliver
A stamped, signed compliance report matched to your plans and ready to upload with your Lakeville 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 Lakeville 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?
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 Lakeville Project?
REScheck is the simplest path for smaller residential projects in Lakeville 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
- Multifamily buildings of three stories or fewer
- Permit applications needing residential envelope documentation on the prescriptive or UA trade-off path
- Detached accessory structures with conditioned space
- Finished basements, attic conversions, and dormer additions on existing homes
COMcheck Projects in Lakeville
COMcheck is required for commercial and larger projects in Lakeville. Reach for a COMcheck when your project involves:
- New mechanical (HVAC) or service water heating systems in commercial spaces
- Medical, dental, and professional office construction
- Restaurant build-outs and retail white-box improvements
- Warehouse, industrial, and light-manufacturing conditioned spaces
- Tenant fit-outs and interior or exterior lighting alterations
