Commercial Building Permit (New Construction / Additions) in Firestone, Colorado

Required for new commercial buildings and additions thereto in Firestone. Reviewed under the 2018 IBC as locally amended by Ordinance No. 1029 (the 'Firestone Building and Construction Code'), with the 2023 NEC for electrical scope. Firestone publishes a dedicated Commercial Permit Submittal Checklist (REV 03.25) distinct from residential submittals, and a separate 2026 Non-Residential Fees sheet covering water tap, impact, and use-tax charges layered on top of the standard valuation-based Building Permit Fee. All plans must be stamped by a Colorado Licensed Architect and Colorado Registered Engineers. Plan review/permit administration is by Town staff; inspections are performed by SAFEbuilt Colorado under contract.

Tips

  • Budget well beyond the building permit fee itself: new commercial projects also owe impact fees ($2,103.54-$7,994.83 per 1,000 sq ft depending on use category), use tax (2.6% of half the valuation), water tap and meter fees, and a $150 commercial administration fee.
  • Three separate submittals are required — Town Building Division, Frederick-Firestone Fire Protection District, and St. Vrain Sanitation District each have their own submittal requirements, and proof of sewer tap purchase must accompany the Town permit submittal.
  • Every contractor on the job (general and all subs) must be licensed with the Town of Firestone before the building permit will be issued — start contractor licensing early. Contractor
  • A commercial-only Footing/Foundation Permit ($2,000) lets sitework/foundations start ahead of the full permit, but additional fees for the full submittal still apply.
  • The 65% plan review fee is due at the time of submittal, not at issuance.
  • Incomplete submittals are rejected outright and reviews are strictly first-come-first-served, so a complete stamped package the first time is the fastest path through review.
