Steps to pull a building permit in Colorado

  1. Step 1: Confirm the work needs a permit (in most cities: structural changes, new electrical circuits, plumbing changes, water heaters, roofs; NOT paint, flooring, minor drywall)
  2. Step 2: Submit stamped plans (an engineer or architect stamp is required for structural work in most cities)
  3. Step 3: Pay the plan check fee (a percentage of estimated project value)
  4. Step 4: Wait for plan review — timeline varies enormously by city (3 days in small towns, 90+ days in San Francisco)
  5. Step 5: Pull the permit and pay the permit fee once approved
  6. Step 6: Schedule required inspections at each phase (foundation, framing, rough, final)
  7. Step 7: Get final inspection sign-off — many cities won't refund your deposit or close the permit without it

Where to file in Colorado

Heads up: Once you've filed, keep a copy of your building permit in your business records. Colorado agencies periodically request proof during audits, tax filings, or when you apply for related permits, and reproducing a lost filing costs more than the original.
