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.

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.
