Commercial Tenant Improvement Permit in Lone Tree, Colorado

The City of Lone Tree does not publish a dedicated Tenant Improvement (TI) permit page or process summary distinct from its general commercial Building Permit. A commercial TI project would be filed as a standard Building Permit application through the Accela portal, subject to the 2021 IBC as adopted and the same shared valuation-based fee table used for all occupancies. RE-CHASED and RE-CONFIRMED live on 2026-07-23 (direct re-fetch of the Permits and Applications page and a sitewide search of cityoflonetree.com for 'tenant improvement'/'submittal checklist', both returning no dedicated TI page, form, or checklist) — this is a confirmed absence on a live primary source, not an unresolved gap.

When you need this permit

  • No standalone TI permit type, application form, or process page could be located on the City's Building, Permits-and-Applications, or Licenses pages — modeled here as a scoped application of the general commercial Building Permit
  • RE-CHASED 2026-07-23: re-fetched the live Permits and Applications page directly and confirmed its 'Land Use & Development Applications' section (the City's own categorized list of non-Building Division application types) lists only 'Site Improvement Plans, subdivisions, rezonings, among other applications' — no 'Tenant Improvement' category is named. Also re-confirmed via the live Building Division FAQ that a zoning verification letter is 'strongly encouraged' before a business applies for a building permit, to confirm the space is zoned for the proposed business use — this pre-permit zoning check is the closest thing to a distinct TI-intake step the City publishes, and it is not itself a separate permit type
  • Governed by the 2021 IBC as adopted, plus applicable fire and accessibility code requirements (2021 IFC, 2017 ICC A117.1)
  • A Business License (or Retail Sales & Use Tax License) is required for the tenant/business operating in the space, separate from the construction permit itself

Tips

  • Since Lone Tree publishes a single 'All Occupancies' fee table, commercial tenant improvement fees use the identical valuation-based schedule as residential work — do not expect a separate commercial-specific rate table.
  • Confirm with the Community Development Department (720-509-1274) whether your specific tenant space and use require additional Site Improvement Plan review, since the City's Land Use & Development Applications process is separate from the Building Division's construction-permit review.
  • Before applying for a TI building permit, the City's own Building Division FAQ strongly encourages requesting a zoning verification letter to confirm the space is zoned for your proposed business use (e.g. a restaurant) — zoning compliance is a precondition for building and sign permit issuance, and non-compliant sites may see permits delayed or denied.

Lone Tree, Colorado has adopted: 2021 International Building Code (IBC), as amended — City of Lone Tree Design Criteria & Codes page; 2021 International Residential Code (IRC), as amended; 2021 International Fire Code (IFC); 2021 International Plumbing Code (IPC); 2021 International Mechanical Code (IMC); 2021 International Fuel Gas Code (IFGC); 2021 International Energy Conservation Code (IECC); 2023 National Electrical Code (NEC); 2017 ICC A117.1 Accessibility Code; Note on Chapter 18 (Building Regulations), Lone Tree Municipal Code: search-indexed content confirms the City has adopted the International Building Code, 2021 Edition, as amended, with a certified copy on file with the City Clerk; a local amendment adds Section 105.3.8 'Soils Test,' requiring a soils test prepared by a Colorado-registered professional engineer at building permit application, with an engineering geologist additionally required for hillside/geological-hazard/steep-slope sites at the Building Official's discretion. Full text of Chapter 18 could not be independently re-verified beyond this indexed excerpt because library.municode.com/co/lone_tree serves an Angular single-page app shell (empty of code text without JS rendering) and returned HTTP 403 to both a standard fetch and a full-browser-header curl retry — this is a partial-confidence caveat on the amendment-detail level only, not on the base code-edition list, which is independently confirmed on the City's own actively-maintained Design Criteria & Codes page.; HB22-1362 statewide energy floor (Colorado): as of 2026-07-06 (this review date), HB22-1362 requires that municipalities/counties updating their building code adopt an energy code achieving equivalent-or-better performance than the 2021 IECC + Model Electric and Solar Ready Code (effective window 7/1/2023-6/30/2026), stepping up to the Colorado Energy Code Board's Model Low Energy and Carbon Code (published 9/2/2025) as the new statewide minimum for any code update on or after 7/1/2026. Lone Tree's currently-published adopted energy code is the 2021 IECC (per its own Design Criteria & Codes page, most recent update not dated on-page) — this predates the 7/1/2026 Model Low Energy and Carbon Code trigger point and does not itself violate HB22-1362, since that stricter floor applies only when a jurisdiction next updates its code. Flagged honestly rather than assumed; confirm current status with the Building Division (720-390-5211) before relying on this for a 2026-cycle project, since Lone Tree could adopt updated codes at any time.. Local amendments apply — see the Lone Tree overview page for the full list.

No. Re-confirmed live 2026-07-23: the City does not publish a dedicated TI permit page, application form, or submittal checklist. Tenant improvement work is filed as a standard commercial Building Permit application through the Accela portal, billed under the same 'All Occupancies' fee table used for all other building permits. The City does recommend requesting a zoning verification letter before applying, to confirm the space is zoned for the proposed business use.
