Commercial Tenant Improvement / Alteration Permit in Grand Junction, Colorado

Permit pathway for tenant finishes, interior remodels, and alterations of existing commercial space within Grand Junction city limits, issued by the Mesa County Building Department. IMPORTANT NAMING NOTE: Mesa County does not publish a separately named 'tenant improvement' or 'tenant finish' permit — TI work is permitted as an 'Alteration to Commercial Building' under the same commercial building-permit process. It is documented here as a distinct entry because its mechanics genuinely differ from new commercial construction: valuation is actual labor-and-material cost rather than the Table 3A square-foot schedule; a dedicated Change in Use/Occupancy fee applies when the occupancy classification changes; first finishes of shell space follow the shell-building valuation deduction; and the City of Grand Junction separately issues its own Change of Use Permit through City Community Development.

When you need this permit

  • A Mesa County building permit is required for tenant improvements/alterations to commercial buildings in Grand Junction; the plan-review fee line on the County fee schedule explicitly covers 'Alteration to Commercial Building' alongside new construction and additions
  • Total Valuation for remodels/alterations is the ACTUAL labor and material cost of the project (Table 2, Note 2) — not the Table 3A square-foot schedule used for new construction and additions
  • If the tenant improvement changes the use/occupancy classification, Mesa County's 'Change in Use/Occupation Valuation Permit Fee' applies: $50.00 under $2,000 valuation, Table 2 valuation-based over $2,000 (Fee #16)
  • The City of Grand Junction separately issues Change of Use Permits through its own Community Development Department (per the City's gjcity.org Permits page) — a City-side land-use step distinct from the County building permit; confirm applicability with City Planning (970-244-1430) when a new tenant's use differs from the prior use
  • Plan submittal follows the same Commercial Plan Review - Submittal Checklist (rev. 9/2025) as other commercial work, applied per scope: drawings sealed/signed/dated per 2024 IBC 107.1, 2 copies, with architectural/mechanical/electrical/plumbing/structural designs, Energy Com-checks, Building Code Analysis Statement, and fire-rated assembly details as applicable ('the following list is a guideline only — other items may be required dependent upon scope of work being performed')
  • City of Grand Junction Fire Department Clearance (970-549-5800) is required when the TI changes egress or affects any fire alarm system, even with no footprint change, per the County's Commercial Building Permit clearance checklist
  • Food Handling clearance from Mesa County Health Department (970-248-6900) is required anytime food preparation, refrigeration, and occasionally open sales areas are undergoing construction or RENOVATION — a common TI trigger for restaurant/grocery fit-outs; Persigo Commercial Waste Water Pre-Treatment Approval (970-256-4180) applies whenever grease/oil/other treatment-affecting waste is introduced
  • Commercial Structural Characteristics form (Assessor's Office) with separate full-size floor plan is required for all permits changing layout, not just those adding footprint
  • Alterations affecting structural, fire, or life-safety elements are reviewed against the 2024 IBC and 2024 IEBC as adopted by Mesa County (enforcement effective September 1, 2025)

Commercial Plan Review Fee — 'Alteration to Commercial Building'Mesa County Building Department Fee Schedule, Table 1A, Fee #1 — the alteration wording is explicit in the fee line, confirming TI/alteration work is billed under the commercial plan-review cap, not the 15% residential cap
Maximum 50% of the Value of the Calculated Permit Fee, as determined appropriate by the Building Department
Change in Use/Occupation Valuation Permit FeeMesa County Building Department Fee Schedule, Table 1A, Fee #16 — applies when the TI changes the occupancy classification; 'Total Valuation' is actual labor and material cost per footnote (1)

Shell-building first finish valuation contextMesa County Building Department Fee Schedule, Table 3A, Note 3

Inspection process

  1. 1

    Rough-In (Framing, Electrical, Plumbing, Mechanical)

    Trade rough-in inspections before cover on altered walls, ceilings, and systems; scheduled via the Mesa County Customer Portal, phone IVR (970-256-1564), or text (SCHEDULE to 844-987-4628). Mesa County publishes a detailed inspection-code sequence only for residential work — confirm the required commercial inspection list at permit issuance

  2. 2

    Final / Occupancy

    Final building and trade inspections; where use/occupancy changed, occupancy sign-off reflects the new classification; Temporary Certificate of Occupancy mechanics per county fee schedule Fee #6 ($100 extension before expiry, $250 for inspections after expiry)

Tips

  • Do not search for a 'tenant improvement permit' by name on Mesa County's site — it does not exist as a named permit. TI work rides the commercial building-permit process as an 'Alteration to Commercial Building' (the fee schedule's own wording), with valuation at actual labor-and-material cost.
  • Two separate change-of-use tracks exist: Mesa County's Change in Use/Occupancy permit fee (building-code side, Fee #16) AND the City of Grand Junction's own Change of Use Permit through City Community Development (land-use side). A new tenant type in an existing space can trigger both.
  • A TI with zero footprint change still triggers GJ Fire clearance if it changes egress or touches the fire alarm system — and that clearance has a published minimum 10-business-day turnaround, so sequence it early.
  • Restaurant fit-outs are the heaviest TI clearance path: Mesa County Health food-handling review, Persigo grease pre-treatment approval, and typically fire clearance for hood-suppression/alarm work.
  • Taking a shell space to first finish? The original shell permit was valued at Table 3A minus 20% — your finish permit is valued at your actual contract cost, so keep the construction contract/estimates on hand at intake.
  • Starting demo or build-out before the permit issues can double the permit fee (Fee #21, at Building Official discretion) — a common temptation on tight tenant possession timelines.

Not by that name. The Mesa County Building Department (which issues all building permits within Grand Junction city limits) processes tenant improvements as an 'Alteration to Commercial Building' under the standard commercial building-permit process. The mechanics differ from new construction: the fee valuation is your actual labor and material cost (Table 2, Note 2), and commercial plan review of up to 50% of the permit fee applies.

Two things can apply: Mesa County's Change in Use/Occupancy Valuation Permit Fee ($50 under $2,000 valuation, Table 2-based above that, Fee #16) on the building-code side, and the City of Grand Junction's own Change of Use Permit, issued by City Community Development, on the land-use side. Contact City Planning (970-244-1430) and Mesa County Building (970-244-1631) before signing a lease if the use is changing.
