Regulation Citation Change Checker

Send an old regulation citation or compliance note and the current jurisdiction/source; get a source-backed drift report showing what is unchanged, changed, moved, or not verified.

What it does

• Compares your existing regulation or code citation against current publicly available official source text.
• Checks whether the cited section still exists, moved, was renumbered, or changed.
• Shows old wording and current wording side by side when both are available.
• Classifies each item as UNCHANGED, CHANGED, MOVED/RENUMBERED, or NOT VERIFIED.
• Cites the current official source URL for every verified result.
• Separates exact source text changes from commentary or inference.
• Flags edition/jurisdiction mismatches instead of guessing.
• Returns a structured JSON summary for reuse in a QA or documentation workflow.

What to send

Send:

• your existing regulation/code citation or note
• jurisdiction, regulator, standard, or document name
• old edition/year if known

Strongly preferred:

• current official source URL
• old source URL or quoted wording when available

Example:

California. My note says "Handrail height 34–38 in. — 2022 CBC §1014.2." Check whether the current published section still says the same thing. Include the official source URL.

What you get back

1. Drift summary
2. Verdict table
3. Old vs current wording when verifiable
4. Renumbering or moved-section notes
5. Official source URL for each verified item
6. NOT VERIFIED flags for unsupported items
7. JSON summary

Good for

• Refreshing recurring compliance notes
• Checking citations before updating a document
• Spot-checking regulation changes between editions
• Finding renumbered or moved sections
• Preparing source-backed change lists for professional review

Limits

Publicly accessible sources only. It does not bypass logins, paywalls, CAPTCHAs, or restricted standards. It reports source-text changes and citation drift; it does not provide legal advice, engineering approval, or professional interpretation. If the current official text cannot be verified, the result is NOT VERIFIED rather than guessed.
