Commercial Building Permit (New Construction & Additions) in Castle Rock, Colorado

Required for construction of new commercial and multifamily buildings, additions, and core-and-shell buildings within the Town of Castle Rock. Issued and inspected by the Town's own Development Services Building Division (not Douglas County) under the 2024 IBC as locally amended by Ordinance No. 2026-017 (effective June 30, 2026), the 2021 IECC, the 2026 NEC, and — depending on the property's fire intensity classification — the 2025 Colorado Wildfire Resiliency Code (effective July 1, 2026). All commercial projects require plan review; the Town's Development Procedures Manual lists 'Commercial/Multi-Family - Core and Shell' as a distinct building permit type from tenant improvement/remodel work.

  • New commercial buildings follow the Town's Development Steps sequence before building permit: Site Development Plan approval (administrative for projects 10 acres or less not adjacent to residential; public-hearing track otherwise), then engineered construction drawings review, then building permit plan review — Town reviews are concurrent across Building, Fire, Utilities, Zoning and Plum Creek Water Reclamation Authority
  • All Fire Protection permits (suppression, alarm, commercial hood systems, tanks, hazmat) are submitted separately and directly to the Castle Rock Fire and Life Safety Division at CRFDFM.com — not through the Building Division

The table is the minimum valuation the Town will accept for new construction
  • New construction, additions and certain exterior work may be subject to 2025 Colorado Wildfire Resiliency Code requirements depending on the property's low/moderate/high fire intensity classification on the Town's wildfire resiliency map

Inspection process

  1. 1

    Deep foundation and footing inspections scheduled independently before concrete placement; items that must be approved before being covered up

  2. 2

    Underground Plumbing Inspection

    Under-slab plumbing scheduled independently prior to cover

  3. 3

    Rough Inspections — Framing, Electrical, Plumbing, Mechanical

    Commercial inspections are scheduled per-discipline on an as-needed basis; all disciplines do not have to be ready at once — partial inspections are standard operating procedure on commercial projects per the Town's Development Procedures Manual

  4. 4

    Insulation / Energy Inspection

    Verification of envelope insulation per the 2021 IECC compliance path shown on the approved plans

  5. 5

    Fire and Life Safety Field Inspections

    Conducted by Castle Rock Fire and Life Safety Division under separate fire permits; field inspection requests require 24-hour notice (303-660-1066); on large projects the fire inspector aims to visit every other day

  6. 6

    Final Inspections — All Disciplines

    Building, electrical, plumbing, mechanical finals plus sign-offs from all authorities over the permit (Fire, Health Department, Utilities, Public Works, Metro Districts, etc.)

  7. 7

    Certificate of Occupancy

    Once all final approval letters are submitted (see Commercial CO Checklist), all authorities have signed off and the inspection card is approved, the CO or Certificate of Completion is issued within 24 hours

Tips

  • Schedule inspections through eTRAKiT until 6:30 a.m. on the requested date, or via the inspection hotline (303-660-1341) by 3:30 p.m. for next-business-day inspections; sites must be accessible 7:30 a.m.-5 p.m.
  • Budget for far more than the permit fee: on new commercial buildings the development impact fees, stormwater impact fee, water/wastewater system development fees (five to seven figures depending on meter size) and the administrative cost allocation recovery fee are due at issuance and typically dwarf the valuation-based permit fee
  • The Site Development Plan comes first — new construction or complete redevelopment SDP review is $4,800 (over 10 acres) or $3,000 (10 acres or less), and construction document review is $3,000 (up to 5 acres, plus $350/acre over 5) before the building permit stage
  • Check the Town's Colorado Wildfire Resiliency map early: properties classified moderate or high fire intensity carry additional exterior material requirements effective July 1, 2026
  • The Chief Building Official may refund up to 80% of the building permit fee if no work has been done, and up to 80% of the plan review fee if the application is withdrawn before any plan review is performed
  • There is no separate 'large commercial' permit track — big-box and shopping-center projects (e.g., Promenade at Castle Rock scale) use the same commercial building permit, but SDPs over 10 acres or adjacent to residential trigger the public-hearing approval track instead of administrative approval
