Change of Use / Change of Occupancy in Commerce City, Colorado

Commerce City does not publish a single named "change of use" or "change of occupancy" permit type -- confirmed against this file's own existing commercial-tenant-improvement-permit entry, whose FAQ already states "Changes of occupancy are explicitly listed under the Commercial Alteration (CALT) permit type," and against eTRAKiT's three permit categories (Commercial/Residential/Other) documented in this file's localAmendments, none of which include a distinct change-of-use code. Where a use/occupancy change is accompanied by construction, remodeling, or reconfiguration, it is processed under the existing CALT permit type. Where NO construction accompanies the change, the practical mechanism running through real, distinct City fee lines is: a Business License (new General Business License, $30.00), a Zoning Verification review ($75.00), and, where Building Safety Division review of the license application is triggered, a separate Business License Review fee ($128.00) -- all confirmed in the city's own Directory of City Fees.

When you need this permit

  • No standalone "Change of Occupancy" or "Change of Use" permit type/code exists among eTRAKiT's Commercial, Residential, and Other permit categories documented elsewhere in this file; a use/occupancy change accompanied by construction, remodeling, or reconfiguration of space is processed under the existing Commercial Alteration (CALT) permit type, whose own FAQ in this file already confirms changes of occupancy are explicitly covered
  • Every business operating within Commerce City must hold a Business License, filed via eTRAKiT with the City Clerk; per the city's own Business Licensing & Permitting guidance, the license is "issued...contingent on occupancy compliance," meaning City staff confirm zoning verification in connection with issuing it
  • A Zoning Verification review ("Zoning Verification/Marijuana Verification," $75.00, Directory of City Fees Section 5.F.5) confirms the newly proposed use is allowed within the property's zoning district; obtaining this before signing a lease or filing a business license application avoids committing to a use the zoning district doesn't allow
  • Where Building Safety Division review of a business license application is required, a separate Business License Review fee ($128.00, Directory of City Fees Section 2.C.1(u)) applies -- distinct from, and in addition to, the $30.00 New General Business License fee itself (Directory of City Fees Section 4.B.1)
  • Under the C3BC as adopted (incorporating the 2021 IBC by reference per this file's codesAdopted), a new building or commercial tenant space cannot be occupied until a Certificate of Occupancy (CO) or Temporary Certificate of Occupancy (TCO) is issued, per the city's own Certificate of Occupancy guidance; the CO/TCO/CC/TCC permit is always filed in eTRAKiT linked to a "parent" permit (e.g., the CALT permit for any construction/alteration accompanying the use change)
  • Prerequisites to CO/TCO issuance include approval of all final inspections on the parent permit -- including, when applicable, South Adams County Fire Department, South Adams County Water and Sanitation District, Public Works, Health Department, and Planning -- per the city's own Certificate of Occupancy page
  • A change of use confirming legal nonconforming status (rather than a newly permitted use) is billed under a separate Directory of City Fees line, "Non-Conforming Certificates," $1,250.00 (Section 5.F.6)
  • If the change of use is accompanied by construction or tenant-improvement work, this file's Commercial Tenant Improvement Permit (CALT) entry applies instead of the construction-free path documented here -- its own requirements list already states plans must reflect a change of occupancy where applicable, including heating/cooling load calculations for existing equipment reused under the new occupancy

Inspection process

    Required only where CALT construction/alteration work accompanies the change of use

  3. 3

    Outside-Agency Final Inspections

    South Adams County Fire Department, Public Works, Adams County Health, and South Adams County Water and Sanitation District finals, where applicable, must be approved before a CO can be finalized -- per this file's existing Commercial Building Permit and Commercial Tenant Improvement Permit entries

    Certificate of Occupancy Issuance

    Filed as a CO/TCO/CC/TCC permit in eTRAKiT, linked to the parent permit, once all applicable prerequisites and agency finals are on record

Tips

  • Commerce City doesn't publish one named "change of use permit" -- three real, separate mechanisms combine to cover it: the Business License process, a Community Development Zoning Verification, and (if construction is involved) the CALT permit type.
  • Get Zoning Verification ($75.00) before signing a lease or committing to a new use -- it's far cheaper to confirm the zoning district allows your intended use upfront than to discover it doesn't after committing to a space.
  • The $128.00 Business License Review fee is separate from, and in addition to, the $30.00 New General Business License fee -- budget for both if Building Safety Division review of your business license application is triggered.
  • If your change of use involves ANY construction, demolition, or reconfiguration -- even minor -- don't try to shortcut it through the Business License process alone; file the CALT permit, since a tenant space's CO cannot be finalized without CALT's own outside-agency finals being on record.

Yes in substance, though Commerce City doesn't publish a single named "change of use permit." A new or amended Certificate of Occupancy is required whenever the authorized use changes, obtained via the city's Business License process ($30.00), a Community Development Zoning Verification review ($75.00), and, where triggered, a Business License Review by the Building Safety Division ($128.00) -- even when no physical construction is involved. Where construction does accompany the change, it is processed under the existing Commercial Alteration (CALT) permit type instead.

No. eTRAKiT's Commercial, Residential, and Other permit categories documented elsewhere in this file do not include a distinct change-of-occupancy code. Changes of occupancy accompanied by construction are processed under the Commercial Alteration (CALT) permit type; changes with no construction run through the Business License and Zoning Verification process instead.
