Commercial Tenant Improvement (TI) / Remodel Permit in City of St. Maries, Idaho

Interior remodel, buildout, or change-of-use work in an existing commercial space within St. Maries city limits has no standalone 'tenant improvement' application, checklist, or fee line published on the City's website (cityofstmaries.org) or in its Fee Schedule (Resolution No. 2026-362, updated 06.22.2026) as of 2026-08-02 — the same documentation gap already found for solar-pv-permit and ev-charger-permit in this jurisdiction file. TI work is processed as a standard Building Permit under St. Maries City Code 9-2-1, using the same Building Permit Application's 'Remodel' or 'Change of Use' Scope of Work checkbox (alongside the 'Commercial' Building Type checkbox), and billed under the City's valuation-based Table 3-A fee table as 'Building Permit - Other Work.' One genuine, code-confirmed distinction: alterations, repairs, and changes of occupancy to an EXISTING building are governed by the 2018 International Existing Building Code (adopted locally as the 'Existing Building Code 2018 of Idaho') — St. Maries City Code 9-1-1(A)(2) — in addition to (or in some respects instead of) the 2018 IBC provisions that govern new commercial construction.

When you need this permit

  • Unlawful to construct, improve, extend, alter, or take any other action requiring a building permit within St. Maries city limits without first procuring the permit — St. Maries City Code 9-2-1(A), applied to interior TI/remodel work the same as new construction.
  • Alterations, repairs, additions, and changes of occupancy to existing buildings are governed by the 2018 International Existing Building Code, adopted as the 'Existing Building Code 2018 of Idaho' — St. Maries City Code 9-1-1(A)(2) — distinct from the 2018 IBC provisions governing new commercial construction under 9-1-1(A)(1). TI work is also subject to the 2018 IMC, 2018 IFC (as adopted/amended by the Idaho State Fire Marshal), 2017 NEC, and 2017 Idaho State Plumbing Code as applicable to the specific scope of trade work performed — St. Maries City Code 9-1-1(A)(6), (7), (8), (9).
  • No dedicated Tenant Improvement or 'Change of Use' application exists — select 'Remodel' or 'Change of Use' under Scope of Work (and 'Commercial' under Building Type) on the standard Building Permit Application.
  • A field survey is not typically required where the work is fully contained within the existing building envelope, per the exception at St. Maries City Code 9-2-1(A)(2)(b); this commonly applies to interior-only TI work that does not expand the building's footprint.
  • Architectural drawings sufficient to meet a recognized financial lending agency's requirements are still required for TI/remodel applications, since the exception in St. Maries City Code 9-2-2(A) only excludes 'a simple boundary structure such as a fence or wall.'
  • The Site Plan Guidelines attached to the Building Permit Application state a site plan is not required only for reroofing; the Guidelines do not separately address whether an interior-only TI project needs a site plan — confirm directly with the Building Department, (208) 245-2577, before submitting.
  • Separate electrical, plumbing, and mechanical permits are required for TI trade work — the same 'Important Notice' that applies to the general Building Permit Application.
  • The initial application may require review by the Planning and Zoning Commission for compliance with Title 11 (Zoning and Subdivisions), which could be relevant where a TI project involves a change of use — St. Maries City Code 9-2-2(E).

Fee schedule

Building Permit - Other Work (TI/Remodel; cost of work applied to Table 3-A) — valuation $1 to $500City of St. Maries Fee Schedule (Resolution 2026-362, updated 06.22.2026), Table 3 / Table 3-A. 'Other Work' fee is based on the contractor's total estimate (labor, materials, overhead, and all other associated costs) applied to Table 3-A; no dedicated TI/remodel line item exists, so this valuation-based table is the governing mechanism, same as for the solar-pv-permit and ev-charger-permit entries in this file.

Inspection process

  1. 1

    Trade Rough-In (Electrical / Mechanical / Plumbing, as applicable)

    Any electrical, mechanical, or plumbing work performed as part of the TI is inspected per the 2017 NEC, 2018 IMC, and 2017 Idaho State Plumbing Code as locally adopted; no TI-specific inspection checklist is separately published by the City, so this follows the general Building Permit inspection framework at St. Maries City Code 9-2-6.

  2. 2

    Final / Certificate of Compliance

    Certificate of Compliance issued once the Building Inspector is satisfied all codes and requirements are met, per St. Maries City Code 9-2-8 — applied to TI/remodel work the same as any other building permit, and required prior to use and/or occupancy of the remodeled space.

Tips

  • St. Maries has no dedicated tenant improvement or commercial remodel permit application, checklist, or fee line published anywhere on its official website as of 2026-08-02 — a TI project is processed as a standard Building Permit ('Other Work,' Remodel/Change of Use scope) under the general valuation-based Table 3-A fee schedule, the same gap already documented for solar PV and EV charging in this jurisdiction.
  • Interior TI work fully contained within the existing building envelope generally will not need a new licensed-surveyor field survey (City Code 9-2-1(A)(2)(b)), but architectural/remodel drawings are still required since only boundary structures are exempted from that requirement.
  • A change of use — as opposed to a like-for-like remodel — is the scenario most likely to trigger Planning and Zoning Commission review under City Code 9-2-2(E) and to implicate the 2018 IEBC's change-of-occupancy provisions; confirm scope-specific triggers with the Building Department, (208) 245-2577, before budgeting or scheduling.
