REScheck is a software tool developed by the U.S. Department of Energy that generates energy code compliance reports for jurisdictions that follow the International Energy Conservation Code (IECC). Some states, including Florida and California, use state-specific compliance forms instead of REScheck.

In most cases, yes. Building departments require documentation showing compliance with the applicable energy code for new construction and many major renovations.

Form 402 is the prescriptive method with fixed requirements. Form 405 is the performance method allowing trade-offs between building components. Form 405 often provides more flexibility for cost-efficient compliance.

We need floor plans, building envelope details (wall types, insulation levels), and window/door specifications. Our team will guide you through exactly what's needed.

We'll identify which components need improvement, such as adding insulation or upgrading windows, to meet code. The Form 405 performance method often allows trade-offs so you can pass without costly changes.

It depends on the scope. Major renovations, additions, and any work requiring HVAC permits typically need energy code compliance documentation. Better check with your local building department.
