Plumbing final inspection checklist template

The most common reasons include improper fixture installation (not properly secured or caulked), missing backflow prevention devices, inaccessible cleanouts, insufficient clearances around fixtures, improper venting, missing documentation, and non-compliant water pressure. Using this checklist helps identify these issues before the inspector arrives, significantly improving your pass rate.

Start by reviewing the checklist well before your scheduled inspection. Walk through each item methodically, physically verifying each point rather than assuming compliance. Take photos of completed work for documentation, mark any issues that need correction, and assign responsibility for fixes. Complete a final verification pass immediately before the inspector arrives.

Have your approved permit and plans accessible, along with any required certifications for backflow prevention devices, pressure test results, manufacturer installation instructions for specialty fixtures, and documentation of any approved variances or modifications. This checklist includes a documentation section to ensure you have everything inspectors commonly request.

Allow at least 24-48 hours to complete the checklist before your scheduled inspection. This gives you adequate time to identify and correct any issues. For complex commercial projects, consider starting even earlier—up to a week before—as these typically have more inspection points and potential compliance issues to address.
