Commercial Building Permit (New Construction / Core & Shell) in Timnath, Colorado

Required for new commercial, industrial, and multi-family structures in Timnath, including Core & Shell buildings for the Town's growing retail/outlet and business-park development. The Town's Building Permit Application lists 'Commercial' as its own distinct project-type checkbox (separate from 'Tenant Finish'). Plan review follows SAFEbuilt Colorado's dedicated 'New Commercial Plan Submittal Procedure'; the Town of Timnath remains the permit-issuing authority.

Fee schedule

Base Commercial Building Permit Fee
As with all other trade/base permit fees in this record, Appendix 4-A's valuation-based base building permit fee table was not locatable online; Show full citationAs with all other trade/base permit fees in this record, Appendix 4-A's valuation-based base building permit fee table was not locatable online; the Appendix 4-A schedule obtained directly from Ordinance No. 5, Series 2024 (Exhibit 4-A) contains only impact fees, sales/use tax rates, and a returned-check fee — no base building-permit valuation fee line. Contact buildings@timnathgov.com or 970-224-3211 for a quote. Note: the Town's residential Valuation Calculator (2022 ICC Building Valuation Data basis) is explicitly limited to residential elements (Main Floor, Basement, Garage, Deck, etc.) and does not include commercial/mercantile/business occupancy valuation categories, so it cannot be used to estimate commercial fees.

Tips

  • The Town's Building Permit Application treats 'Commercial' (new construction/Core & Shell) and 'Tenant Finish' as two distinct project-type checkboxes — use the separate commercial-tenant-improvement-permit entry for interior build-outs of existing commercial space.
  • The non-residential Capital Improvement Impact Fee rates changed substantially effective September 2, 2024 (Ordinance No. 5, Series 2024) — Police and Transportation fees per 1,000 SF dropped, Public Buildings rose nearly 3x, and Stormwater was zeroed out. Always pull the current Appendix 4-A table (via the adopting ordinance) rather than an older cached fee sheet.
  • For a Core & Shell commercial building permit, three of the four non-residential impact fees (Police, Public Buildings, Transportation) are deferred and only become due when the tenant-finish permit is later issued — budget for this two-stage fee timing rather than assuming everything is due at shell permit issuance.
  • The Town's own 'Licenses, Fees, and Charges' page lists 'Retail Fees' and 'Office Industrial Fees' as named buttons, but those two and the adjacent 'Building Permit Fees', 'General Permit Fees' and 'One-Stop Fees' buttons all carry an empty href="" with no fee document attached — all five lead nowhere. Ask the Town directly for the applicable fee figures.
  • A pre-application meeting with SAFEbuilt Colorado and the fire protection district is optional but recommended by the Town to speed up commercial plan review.
  • No published SLA exists for commercial review time, but a real Town of Timnath economic-incentive letter (civicweb document 110110, dated 3/14/2024) shows an actual $500,000 commercial tenant-finish project ran from permit application to permit issuance in about 88 calendar days — useful as a rough real-world data point when budgeting a project timeline, though it is one project's outcome, not a guaranteed turnaround.
