Commercial Tenant Finish / Remodel / Change of Occupancy Permit (Tenant Improvement) in Parker, Colorado

Required for finishing out a commercial space for its first occupant (Tenant Finish), remodeling an already-finished commercial space where the occupancy classification is not changing (Remodel), or converting a commercial space to a new occupancy classification (Change of Occupancy). All three fall under a single COMMERCIAL Tenant Finish/Remodel/Change of Occupancy plan submittal checklist and review track at the Town of Parker Building Division, sharing the same commercial plan-check-deposit and review-timeline treatment as new commercial construction, but without the excise tax charged on new commercial buildings.

When you need this permit

  • Tenant Finish: the FIRST TIME the space is being occupied — a Certificate of Occupancy will be issued
  • Remodel: the space has been previously finished by a prior tenant and the occupancy classification is not changing; Remodel permits may not require every item on the checklist — contact the Building Division to confirm scope
  • Change of Occupancy: the space's occupancy classification is changing — a Certificate of Occupancy will be issued
  • All documents must be submitted electronically (PDF only), maximum 50MB per file, filenames with no special characters, and a Description field filled in or plan review will not proceed
  • One complete plan set stamped by required engineers: Architectural (floor/roof/schedules/sections), Structural (with calculations if any revisions), Mechanical stamped by engineer, Plumbing stamped by engineer (see C.R.S. 12-4-101)
  • A project manual, if used, complete and stamped
  • An energy analysis (Com-Check) of both the electrical portion and the mechanical portion is required; if additional HVAC units are being installed, a Mechanical Com-Check is specifically required
  • Heating and cooling load design temperatures: Winter -3°F / Summer 90°F outdoor dry bulb, Winter 70°F / Summer 75°F indoor dry bulb
  • A plan review deposit fee of 50% of the plan review fee is required
  • Applicable codes are the Town's current adopted codes/design criteria/amendments (see the Town of Parker Building Codes page) — do not rely on a fixed code-year list, given the June 30, 2026 transition to the 2024 I-Codes described elsewhere in this file

Fee schedule

Building Permit Fee — total valuation $1.00 to $500.00Same Table 3.1 valuation-based schedule as residential/commercial new construction — see the residential-building-permit entry in this file for the full tier breakdown. For tenant finish, remodel, change-of-occupancy, and other non-new-building commercial permits, valuation is the value of the permitted work as stated by the applicant (not the IBC per-square-foot chart used for new buildings).

Plan Check DepositConfirmed on the Commercial Tenant Finish/Remodel Plan Submittal Checklist (July 16, 2026) and the Building Permit Fees page ('Commercial: Half of the estimated plan check fee'). NOTE: two older Town-published sources — the 2023 combined Commercial/Multi-Family/SFD checklist and a stale 2018 'Tenant Finish' checklist still linked from the Permit Information page — instead state a flat $100.00 plan review deposit for this permit type. Given the July 2026 checklist is the most recently dated primary source and matches the Building Permit Fees webpage's current language, this entry treats 50% of the plan review fee as the current figure, but this is a genuine unresolved discrepancy between Town-published documents rather than a drift artifact — confirm directly with the Building Division (303-841-1970) before relying on either figure for budgeting.

Inspection process

  1. 1

    Rough-In

    Mechanical, electrical, and plumbing rough-in as applicable to the scope of the tenant finish/remodel, per the stamped MEP plan sheets required at submittal

  2. 2

    Final

    All work complete per approved plans. A Certificate of Occupancy is issued for Tenant Finish (first-time occupancy) and Change of Occupancy permits; a straight Remodel of an already-finished space where the occupancy classification is not changing does not trigger a new Certificate of Occupancy, per the Town's Building Permit Type & Sub-Type Definitions

Tips

  • Parker's own checklist explicitly distinguishes Tenant Finish (first-time occupancy, CO issued), Remodel (previously finished space, same occupancy, CO not reissued, and not all checklist items may apply), and Change of Occupancy (occupancy classification changing, CO issued) — confirm which sub-type applies before submitting, since it affects both the document checklist and the Certificate of Occupancy outcome.
  • If additional HVAC units are being installed as part of the tenant finish or remodel, a Mechanical Com-Check energy analysis is specifically called out as required, in addition to the electrical Com-Check.
  • Parker's EZ Commercial Permits track (referenced on the Town's Building Division page) covers small, non-structural commercial projects under 1,200 sq ft — worth asking about for minor tenant-finish scopes before going through the full commercial plan-review process.
  • There is a genuine, unresolved conflict between Town-published documents on the plan review deposit for this permit type: the current (July 2026) checklist and the Building Permit Fees webpage say 50% of the plan review fee, while two older Town PDFs (a 2023 combined checklist and a 2018 Tenant Finish checklist, both still reachable/linked from the Town's own site) say a flat $100.00 — confirm directly with the Building Division rather than assuming either figure.

Frequently asked questions

It depends on the sub-type. Tenant Finish (first-time occupancy) and Change of Occupancy permits result in a new Certificate of Occupancy. A straight Remodel of a space that was already finished by a previous tenant, with no change in occupancy classification, generally does not — per the Town's own Building Permit Type & Sub-Type Definitions.

The Town's current (July 2026) checklist and its Building Permit Fees webpage both state 50% of the plan review fee. Note that two older Town-published documents instead state a flat $100.00 for this permit type — this is an unresolved conflict in the Town's own materials, so confirm the current figure with the Building Division (303-841-1970) before budgeting.

Parker's published plan-review target for a commercial tenant finish / remodel / change of occupancy permit (tenant improvement) is 14–28 business days.
