Change of Use / Change of Occupancy Permit in Nunn, Colorado

The Town of Nunn does not publish a distinct 'Change of Use' permit application, checkbox, or fee line item, but a change of use is unambiguously permit-required: NMC 15.08.010 (General provisions) makes it 'unlawful to erect, construct, reconstruct, alter, move, locate, use, or change the use of any building or other structure within the town limits without obtaining a building permit.' The Town's own generic Building Permit Application states verbatim: 'Any change in the use or occupancy of the building must be approved prior to proceeding with consruction [sic].' A change of use is therefore processed through the identical Town Clerk's Office → SAFEbuilt intake used for every other Nunn permit type, marking 'Other' on the application's Type field and describing the occupancy change under 'Description of Work' and 'Proposed Use.' Substantively, occupancy classification changes fall under Chapter 10 ('Change of Occupancy') of the 2018 International Existing Building Code, adopted by reference at NMC 15.04.130 with no local amendment to that chapter. Separately, at the zoning level, NMC 17.40.040 (Change in use) restricts what a legally nonconforming use may change into.

When you need this permit

  • NMC 15.08.010: it is unlawful to 'use, or change the use of any building or other structure' within town limits without a building permit — a change of use requires a permit even absent new construction
  • The Town's own Building Permit Application form states verbatim: 'Any change in the use or occupancy of the building must be approved prior to proceeding with consruction [sic]' — approval must be obtained before the new use/occupancy proceeds
  • No dedicated 'change of use' checkbox exists on the application: the 'Type' field offers only New Build / Addition / Remodel / Other, and 'Proposed Use' offers Residential (One Family / Multi Family) or Commercial/Industrial (Shell Only / Tenant Finish); a change-of-use application marks 'Other' and describes the change under 'Description of Work'
  • Substantively governed by Chapter 10 ('Change of Occupancy') of the 2018 International Existing Building Code, adopted by reference at NMC 15.04.130, chapters 1 through 16 inclusive, with no local amendment to Chapter 10 specifically (confirmed by reading NMC 15.04.130 in full: its only three amendments concern fire-code cross-references, the code title, and moved-structure conformance)
  • At the zoning level, NMC 17.40.040 (Change in use) prohibits changing a legally nonconforming use to a use of lower or less restrictive classification; a nonconforming use may be changed only to a use of the same or higher classification
  • As with all Nunn building permits, the application and any supporting description are submitted to the Town Clerk's Office (or emailed to kendra.minch@townofnunnco.gov), then forwarded to SAFEbuilt for review
  • CONFIRMED ABSENCE (see also the residential-building-permit entry): Nunn has no distinct commercial-building or tenant-improvement (TI) permit type either — commercial/industrial 'Shell Only' or 'Tenant Finish' scopes, including any accompanying change of use, are processed through this same generic Building Permit Application

Fee schedule

Town Admin Fee (Building Permit) + Use TaxNo change-of-use-specific line item is published in the Town of Nunn's 'Fee Schedule, Effective January 22nd, 2026' (verified by rendering the PDF's two-column layout to an image and reading it directly). A change of use is billed under the same general two-tier Building Permit Admin Fee structure as every other undifferentiated Nunn permit type; which tier applies is not Town-published. This is the Town Clerk's own flat component only — SAFEbuilt's own valuation-based component, if any accompanies the change of use, remains unpublished.
$50.00 flat Admin Fee if processed as a 'One Stop' permit, or $75.00 if SAFEbuilt plan review is required, plus 2% Use Tax on all Building Permits

Inspection process

  1. 1

    Final Inspection (if accompanying construction/alteration work)

    Required where the change of use is accompanied by construction, alteration, or trade work; scheduled with SAFEbuilt. A pure occupancy-classification change with no physical construction may not require a SAFEbuilt field inspection, but Town approval is still required before the new use commences per the Building Permit Application's own terms

See the full Nunn inspection guide — scheduling & re-inspection fees →

Tips

  • Get written Town approval on a change of use or occupancy BEFORE proceeding — the Town's own Building Permit Application explicitly conditions proceeding on prior approval, independent of whether construction is involved.
  • There is no dedicated 'Change of Use Permit' form in Nunn — use the standard Building Permit Application, mark 'Other' under Type, and fully describe both the current and proposed use.
  • If the space involves a legally nonconforming use, NMC 17.40.040 prohibits changing to a LOWER or less restrictive use classification — confirm zoning compatibility with the Town Clerk's Office before applying.
