The useful answer is on the permit and the provisions that govern it. Before scheduling fabrication, identify what expires, what event starts the clock, and what must happen before the deadline. A number of days without those details is not a usable schedule.
Review time is spent evaluating an application. Permit validity concerns an approval after issuance. Display duration concerns how long a sign may remain or operate. Do not substitute one for another.
Build a calendar with separate clocks
| Clock to ask about | Trigger to identify | Evidence to retain |
|---|---|---|
| Application completion or review | Filing, payment, or acceptance as complete | Intake receipt and outstanding-item notice |
| Start of authorized work | Issuance or another specified date | Permit conditions and definition of starting work |
| Interruption of work | Suspension or abandonment as defined by the provision | Work and inspection records |
| Completion or final inspection | The event specified by the approval | Inspection results and closeout requirements |
| Temporary display or renewal | An event, installation date, or fixed date | Approved display dates and renewal conditions |
This is a list of questions, not a claim that every permit has every clock. Record “not applicable” only after checking the relevant approval.
Do not borrow a deadline from a model code
ICC publishes model building safety codes. Identify the project's adopted edition, amendments, administrative provisions, and sign approval. A deadline you find in a model code is not the life of your sign permit.
Also identify separate approvals. A zoning decision, building permit, electrical permit, and permission to occupy a public right-of-way need not share conditions or expiration events. Ask which approvals are required and whether one depends on another.
A hypothetical scheduling example
Imagine a fictional approval issued on April 1 that expressly requires site work to begin by June 30. Delivery is scheduled for July 10. Ordering materials in May does not, by itself, establish that the site-work condition was met. The project manager needs the office's interpretation and, if available, an approved extension before relying on the later delivery date.
Those invented dates illustrate a scheduling problem, not a standard permit term. Assign responsibility for the deadline and set a reminder early enough to resolve an extension request.
Before requesting an extension
- Find the permit number, issue date, approved drawings, conditions, and amendments.
- Confirm whether the request must be received or approved before expiration.
- Ask what progress evidence, explanation, fee, or revised drawing is needed.
- Check whether a lapse requires reinstatement or a new application, and which rules would then apply.
- Retain the written extension and new conditions with the original permit.
An unanswered request is not evidence of an extension. An old sign's existence does not prove that its approval covers replacement, relocation, or conversion to a digital display.
Use the project-confirmation checklist for records that a code search alone cannot supply.
