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 FeeAs with all other trade/base permit fees in this file, 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.
Not published online
Police Impact Fee (non-residential)CURRENT rate effective 9/2/2024 per Ordinance No. 5, Series 2024, Exhibit 4-A (Appendix 4-A), amending Sec. 4-6-50(a) — supersedes the prior $330.00/1,000 SF rate. For a non-residential Core & Shell building permit, this fee is only assessed and payable at issuance of the tenant-finish permit, not at Core & Shell issuance (Sec. 4-6-50(a)(1)).
$116.00 per 1,000 square feet of non-residential building
Public Buildings Impact Fee (non-residential)CURRENT rate effective 9/2/2024 per Ordinance No. 5, Series 2024, Exhibit 4-A — supersedes the prior $401.00/1,000 SF rate. Same Core & Shell / tenant-finish deferral as the Police Impact Fee (Sec. 4-6-50(c)(1)).
$1,197.00 per 1,000 square feet of non-residential building
Transportation Impact Fee (non-residential)CURRENT rate effective 9/2/2024 per Ordinance No. 5, Series 2024, Exhibit 4-A — supersedes the prior $4,954.00/1,000 SF rate (this is one of the few impact fees that decreased). Same Core & Shell / tenant-finish deferral (Sec. 4-6-50(e)(1)).
$4,499.00 per 1,000 square feet of non-residential building

Unlike the Police/Public Buildings/Transportation fees, the ordinance text does not carve out a Core & Shell deferral for this fee (payable at issuance of any building permit for any structure), though it is currently zero regardless.
$0.00 per 1,000 square feet of non-residential building
Parks, Open Space and Trails Impact FeeOrdinance No. 5, Series 2024, Exhibit 4-A explicitly states this fee is 'Not applicable to non-residential buildings.'

Tips

  • The Town's Building Permit Application treats 'Commercial' (new construction/Core & Shell) and 'Tenant Finish' as two distinct project-type checkboxes — use this file's 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 as of this extraction both (and the adjacent 'Building Permit Fees'/'General Permit Fees'/'One-Stop Fees' buttons) have empty/non-functional links with no fee document attached — a confirmed gap, not a broken fetch on this end.
  • 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.

Yes.
