Commercial Tenant Improvement Permit (Tenant Finish / Commercial Alterations) in Johnstown, Colorado

Required for tenant finish and alteration work in existing commercial buildings in Johnstown. The Town's own Building Permits page names 'Commercial tenant finish' as an explicitly permit-required work type, and its Building Permit Fees page maintains a distinct 'Commercial Alterations/Additions' review category, defined as 'the alteration or addition of an existing commercial structure' — the category under which tenant finish is processed. 'Change of Use of a commercial space, or a home to a business/commercial space' also independently triggers a permit. Distinct from Commercial New in its fee stack (no tap/impact/park fees) though it shares the same valuation-based permit fee table and 65% plan-review rate.

Tips

  • Johnstown's own term is 'Commercial tenant finish' — it is a named permit-required work type on the Building Permits page, processed under the 'Commercial Alterations/Additions' review category. There is no separate TI fee schedule or TI-specific timeline; the distinction from Commercial New is the fee stack (no tap, impact, park, or raw-water fees attach to alterations).
  • A change of use alone — converting a commercial space to a different use, or a home to a business — triggers a permit in Johnstown even if little construction is involved. Factor this into lease timelines.
  • Unlike new commercial construction, tenant finish permits can be initiated online through eTRAKiT — the Building Department page's online restriction names only 'new commercial construction.'
  • Restaurant and food-service tenant finishes involve Town-performed Grease Interceptor and Backflow inspections (24-48 hour notice for water-related inspections), separate from the SAFEbuilt/ProCode building inspections requested by 4 p.m. the prior business day.

Johnstown, Colorado has adopted: 2024 International Building Code (IBC) — Town of Johnstown Building Codes page, https://www.johnstownco.gov/211/Building-Codes, adopted per Ordinance No. 2025-274 (enacted September 15, 2025); 2024 International Residential Code (IRC), per the same ordinance and Building Codes page; 2024 International Fire Code (IFC); 2024 International Fuel Gas Code (IFGC); 2024 International Energy Conservation Code (IECC); 2024 International Mechanical Code (IMC); 2024 International Plumbing Code (IPC); 2023 National Electrical Code (NEC); Colorado Wildfire Resiliency Code, as adopted/referenced on the Town's Building Codes page; Colorado Model Electric and Solar Ready Code, as adopted/referenced on the Town's Building Codes page; Johnstown Municipal Code, Chapter 18 (Building Regulations); NOTE (data-integrity flag): Several individual project-specific pages on johnstownco.gov (Addition, Electrical, Roofing, Siding, Water Heater, Furnace, Air Conditioning, Basement Finish, Residential Solar) still display a stale 'applicable codes' footer citing the superseded 2018 I-Code suite (with only the NEC correctly updated to 2023) — this appears to be unupdated boilerplate predating Ordinance No. 2025-274's September 2025 adoption of the 2024 I-Codes. The Building Codes landing page (2024 codes) is treated as the current governing citation in this corpus; the discrepancy itself is disclosed rather than silently resolved, since the individual permit pages have not been corrected as of this review.. Local amendments apply — see the Johnstown overview page for the full list.

Yes. 'Change of Use of a commercial space, or a home to a business/commercial space' is its own line item on the Town's permit-required list, independent of tenant-finish construction work.
