Commercial Building Permit in City of St. Maries, Idaho
Required for new commercial construction within St. Maries city limits. St. Maries has no standalone commercial-specific application, checklist, or fee schedule — commercial projects use the same Building Permit Application (with 'Commercial' as one of the form's Building Type checkboxes) and the same valuation-based Table 3-A fee table (Resolution No. 2026-362, updated 06.22.2026) as residential construction, under St. Maries City Code 9-2-1 through 9-2-10. The one confirmed commercial-specific difference is a higher Planner review fee (Table 2: $100 commercial/industrial/non-residential vs. $60 residential). Commercial work is governed primarily by the 2018 International Building Code (IBC) rather than the 2018 International Residential Code (IRC) that governs single-family/duplex/townhome/multi-family dwelling work.

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 commercial construction the same as any other building type.
- Governed primarily by the 2018 IBC, with Idaho amendments (adopted as 'Building Code 2018 of Idaho') — St. Maries City Code 9-1-1(A)(1) — rather than the 2018 IRC (Parts I, II, III, IX), which St. Maries City Code 9-1-1(A)(3) applies specifically to residential construction. Commercial work is also subject to the 2018 International Mechanical Code, the 2018 International Fire Code as adopted/amended by the Idaho State Fire Marshal, the 2017 National Electrical Code, and the 2017 Idaho State Plumbing Code — St. Maries City Code 9-1-1(A)(6), (7), (8), (9).
- A written statement from a licensed surveyor certifying a completed field survey with property corners located and marked must be submitted with the application, unless the work is demolition-only, fully contained within the existing building envelope, or an acceptable prior survey with visible original corner markers already exists — St. Maries City Code 9-2-1(A)(1)-(2).
- Architectural drawings sufficient to meet a recognized financial lending agency's requirements are required — St. Maries City Code 9-2-2(A).
- The initial application may require review by the Planning and Zoning Commission for compliance with Title 11 (Zoning and Subdivisions) of the city code — St. Maries City Code 9-2-2(E).
- No local-code provision, Building Department webpage, or Forms-page document found as of 2026-08-02 describes commercial plan review being routed to a regional/county building official, the Idaho Division of Building Safety, the Idaho State Fire Marshal's office, or a third-party contracted firm — St. Maries City Code Title 9 describes a single 'building inspector' (Building Official Jacob Parsons) issuing all building permits with no separate commercial pathway. This jurisdiction's own self-administration was independently confirmed via cityofstmaries.org and City Code Title 9; whether the current Building Official holds ICC certification specific to commercial-scope plan review was not independently confirmed and should be verified directly with the Building Department, (208) 245-2577, before relying on local review for a complex commercial project.
- Separate electrical, plumbing, and mechanical permits are required — noted as an 'Important Notice' on the Building Permit Application, applying to commercial the same as residential.

Inspection process
- 1
Designated Points of Construction
St. Maries City Code 9-2-6 requires the Building Inspector to inspect the structure at 'designated points of construction as set forth in the building code adopted by the city,' and prohibits construction from proceeding beyond each designated inspection point until the inspection is completed and signified on the building permit. No discrete commercial-specific inspection checklist is separately published by the City as of 2026-08-02; the adopted 2018 IBC/IFC/IMC govern the specific inspection points for commercial work.
- 2
Final / Certificate of Compliance
A Certificate of Compliance (a copy of the signed and dated inspection record) is issued once the Building Inspector is satisfied all codes and requirements are met, and must be issued prior to use and/or occupancy — St. Maries City Code 9-2-8.

Tips
- There is no separate commercial building permit application or fee table — the same Building Permit Application and Table 3-A valuation-based fee schedule used for residential construction apply, with the 'Commercial' Building Type checkbox as the only form-level differentiator.
- Budget for the higher Table 2 Planner review fee: $100.00 for commercial/industrial/non-residential work versus $60.00 for residential — this is the one confirmed commercial-specific fee difference found in the City's published Fee Schedule.
- No evidence was found that St. Maries contracts commercial plan review or inspection out to Benewah County, a regional building official, or a third-party firm — confirm current Building Official certification/capacity for larger commercial projects directly with the Building Department, (208) 245-2577, before assuming purely local review for a complex or high-occupancy project.
- Commercial construction is governed by the 2018 IBC (not the 2018 IRC used for dwellings) plus the 2018 IFC as adopted and amended by the Idaho State Fire Marshal — confirm fire-code-specific requirements (e.g., fire alarm/sprinkler plan submittal) directly with the Building Department, since the City's own published materials do not separately break out fire-code review procedure.
