Every building permit has an expiration date, and missing it can cost you thousands in fees, project delays, and even code re-inspections. Whether you’re a general contractor juggling multiple job sites or a homeowner managing a renovation, understanding permit timelines is essential.

How Long Do Building Permits Last?

Most jurisdictions issue permits that are valid for 6 to 12 months from the date of issuance. However, this varies significantly by city:

  • Los Angeles (LADBS): 12 months from issuance, with options to extend
  • San Diego (DSD): 180 days from issuance for most permits
  • Denver: 12 months, with work progress requirements
  • Charlotte: 6 months from date of issuance

The clock typically starts ticking from the issue date, not when you start construction. Some jurisdictions reset the timer when an inspection is completed, but don’t count on it.

What Happens When It Expires?

When a permit expires, the consequences depend on your jurisdiction but generally include:

  1. Work stoppage – You cannot legally continue construction
  2. Reinstatement fees – Usually 50-100% of the original permit fee
  3. Re-inspection requirements – Previous inspections may need to be repeated
  4. Plan re-review – If codes have changed, your plans may need updating
  5. Potential penalties – Fines for working without a valid permit

How to Prevent Permit Expiration

The best strategy is prevention:

  • Track all your permits in one place with their expiration dates
  • Set up reminders at 60, 30, and 14 days before expiration
  • Request extensions early – most cities allow one extension if requested before expiration
  • Keep inspections on schedule – regular progress resets the clock in many jurisdictions

When to Request an Extension

Most jurisdictions allow at least one extension if you apply before the permit expires. The key is timing:

  • Apply at least 30 days before expiration
  • Have documentation showing work progress
  • Be prepared to pay an extension fee (usually 25-50% of the original fee)

Once a permit has actually expired, the reinstatement process is more expensive and time-consuming than a simple extension.

Automate Your Permit Tracking

Manually tracking permit dates across multiple job sites is how deadlines get missed. SignedOff automatically monitors your permits and sends email alerts before expiration, so you never have to worry about a permit lapsing while you’re focused on the job.
