Commercial Tenant Improvement / Commercial Building Permit in Frederick, Colorado

Required for new commercial construction and tenant improvements in the Town of Frederick. Reviewed under the 2024 IBC as locally adopted, with all discipline-specific plans wet-stamped by the applicable Colorado-licensed design professional. The Town's own submittal checklist does not explicitly differentiate tenant improvement scope from new commercial construction; TI projects are expected to submit a scaled-down version of the same document set (typically without new site/civil/grading/utility-connection plans).

Tips

  • Fire alarm and fire sprinkler plans go to the Frederick Fire Department separately from the Building Department's commercial plan review — route those documents to Fire directly rather than bundling them with your Building Department submittal to avoid delay. The live All-Commercial checklist text itself names 'tenant finishes' explicitly in this Fire Protection routing instruction ('For fire alarm, sprinkler, commercial building, tenant finishes, kitchen hoods, haz-mat and IGH piled storage... email to FFFD').
  • The Town's commercial checklist does not spell out a distinct, lighter tenant-improvement track because it doesn't need to — the same Building Permit Application asks the applicant to classify the work as 'New, addition, alteration, repair, move, other,' and the checklist's site/civil section already lists 'Structures – Proposed and existing, including sheds, barns, decks, patios, etc.' as things to show only where they exist/are proposed. For straightforward TI work with no new utility connections or grading, confirm with the Building Department which site/civil elements can be omitted, but there is no separate TI document set being missed — this is Frederick's actual single-track process, confirmed against the live checklist text.

Treat the Building Codes page list — 2024 IBC, IRC, IECC, IMC, IPC, IFGC, IEBC, ISPSC, IPMC plus the 2023 NEC — as the governing adopted-code list, and confirm the current edition with the Building Department at 720-382-5516 before finalizing a code analysis, since the checklist has not been updated to match.. Local amendments apply — see the Frederick overview page for the full list.

The Town's All Commercial submittal checklist does not explicitly exempt tenant improvements from site/civil plan requirements, but a TI with no new grading, drainage changes, or utility connections from the road would typically not need those elements — confirm scope-specific requirements with the Building Department before submittal.
