How Building Inspectors Review REScheck Reports for Permit Approval

When applying for a residential building permit, many jurisdictions require a REScheck report to verify compliance with the International Energy Conservation Code (IECC). Inspectors use this report to confirm that insulation, windows, and other building-envelope components meet minimum energy-efficiency requirements before construction begins.

Understanding how inspectors review a REScheck report can help prevent permit delays and ensure your project is approved quickly. Today, we look at how building inspectors review rescheck reports for permit approval.

What a REScheck Report Is Used For

A REScheck report is a compliance certificate generated using U.S. Department of Energy REScheck software. It demonstrates that a home’s building envelope meets IECC energy-code requirements.

Inspectors review the report to confirm:

• climate zone accuracy

• insulation R-values

• window and door U-factors

• wall, ceiling, and foundation assemblies

• overall pass/fail compliance status

If the report passes, it is typically accepted as documentation for residential energy-code compliance during the permitting process.

Sections Inspectors Check First

Most building departments review several key areas at the top of the REScheck report before issuing permit approval.

1. Project Information

Inspectors verify:

• project address

• jurisdiction

• building type

• conditioned floor area

Incorrect location data can result in the wrong climate zone being applied, which may invalidate the report.

2. Climate Zone Selection

Energy requirements vary by climate zone. Inspectors confirm that the selected zone matches the project location because insulation and window performance thresholds depend on it.

3. Insulation Values (R-Values)

Inspectors review insulation levels for:

• exterior walls

• ceilings and roofs

• floors over unconditioned space

• slab edges and foundations

These must meet or exceed IECC minimum requirements or comply through the UA tradeoff method.

4. Window and Door Performance (U-Factors)

Window and door U-factors are checked against climate-zone limits. If incorrect values are entered, the report may fail even when insulation levels are sufficient.

5. Compliance Result (Pass/Fail Certificate)

At the top of the REScheck certificate is the most important line inspectors look for:

“Pass”

A passing result confirms the proposed envelope meets IECC compliance requirements.

Where Compliance Appears on the REScheck Certificate

Inspectors typically look at the summary compliance page first. This section shows:

• compliance status

• total UA comparison

• building assembly performance values

• tradeoff adjustments (if used)

If the report passes, the remaining pages are usually reviewed only for confirmation.

Common Reasons REScheck Reports Fail

A failed REScheck report does not necessarily mean a project cannot be approved. In many cases, small adjustments resolve compliance issues quickly.

Typical causes include:

• incorrect climate zone selection

• missing insulation specifications

• window U-factors entered incorrectly

• unconditioned spaces modeled as conditioned

• foundation insulation omitted

• assembly types mismatched to plans

Correcting these inputs often produces a passing result without changing the design significantly.

How Inspectors Use REScheck During Permit Review

During permit review, building departments typically:

1. confirm jurisdiction and climate zone

2. verify insulation assemblies match construction drawings

3. review window performance values

4. confirm compliance status is “Pass”

5. accept the report as envelope compliance documentation

Once approved, the REScheck certificate becomes part of the permit record.

How to Submit a REScheck Report With Permit Applications

Most jurisdictions accept REScheck reports submitted:

• as a PDF attachment

• with construction drawings

• alongside Manual J calculations (when required)

• during initial permit submission or plan review

Requirements vary slightly by city or county, but the compliance certificate format is standardized nationwide.

Who Can Order a REScheck Report

REScheck reports can be prepared for:

• homeowners

• builders

• architects

• designers

• contractors

They do not need to be created by the building department itself and are commonly submitted as third-party compliance documentation.

How Long REScheck Reports Typically Take

Most residential REScheck reports are completed within hours once plans are submitted. Simpler additions and smaller projects are often delivered the same day.

Fast turnaround helps prevent delays during permit review.

When a Manual J Report Is Also Required

A REScheck report verifies envelope compliance. A Manual J load calculation determines HVAC sizing.

Some jurisdictions require both reports before issuing permits, especially for new construction or equipment replacement projects.

Ordering a REScheck Report for Permit Approval

To prepare a REScheck report, most providers need:

• floor plans

• insulation details (if available)

• window and door sizes

• project location

Once completed, the compliance certificate can be submitted directly with permit documents.

Most building departments accept REScheck compliance reports generated using DOE-approved software as part of the residential permitting process.
