Frequently asked questions

Is InspectorToolbox really free?

Yes. All five tools run in your browser with no account and no paywall. Your data is stored locally on your device and never uploaded.

Does InspectorToolbox replace a licensed inspector or legal advice?

No. It is an informational reference for common inspection practice. Frequency baselines are general summaries — your Authority Having Jurisdiction (AHJ) and the current editions of applicable codes take precedence.

Where does my checklist and reminder data go?

Nowhere. Runs, tracked assets, and your provider book are saved in your browser's local storage. There is no server, no account, and no tracking.

Are the checklists copies of NFPA or OSHA standards?

No. All checklist items are in-house descriptions of common inspection actions, with citation pointers where relevant. No standard text is reproduced — this keeps the tool free of licensing restrictions.

How does the fire door gap measurer work?

Enter your measurement in inches (decimal or fraction) and pick the gap type. The tool compares it against commonly used installation bands — for example, a 1/16"–3/16" band for door-edge gaps — and tells you whether it is within, below, or above the band, with typical next steps.
