01 / YOUR PERMIT
Calculate your risk window.
Nothing here checks a live permit record. Activity, inspections, renewals and city approvals can change the answer.
02 / YOUR ESTIMATE
Your timeline
You'll see the relevant dates, the rule used, and what you still need to verify.
03 / ORIGINAL RULES
Every threshold has a source.
Published rules checked on . Local ordinances, issued permit conditions and case-specific extensions take precedence over this tool.

WHAT WE DO NOT KNOW
A date is not an official permit status.
We do not have access to your city's live permit or inspection system. A failed inspection, incomplete paperwork, an official extension, stopped work or a closed permit can change the answer. For an expiring permit, verify the exact deadline and whether work is authorised directly with the municipal permit office.
