Permits expire if work is not commenced within _____ days of issuance.

The correct answer is 180 days because most jurisdictions, including North Carolina, establish a timeframe during which a permit must be acted upon to prevent it from expiring. The standard for many types of permits—be it plumbing, electrical, or general construction—often allows for 180 days before requiring action to maintain its validity. This period reflects the need for contractors and homeowners to have flexibility in planning and executing construction or renovation work, which can depend on numerous factors such as funding, scheduling, or the procurement of materials.

In a practical sense, having a 180-day window before a permit expires encourages compliance with regulatory requirements while also accommodating potential delays that many projects experience. This understanding is crucial for plumbers and contractors to ensure they stay informed about permit statuses and to plan their work accordingly, reducing the risk of having to reapply or face additional costs related to expired permits.
