Commercial Building Permit (New Construction, Additions & Remodels / Tenant Improvement) in Ammon, Idaho

Ammon requires a commercial building permit (new construction, additions & remodels / tenant improvement) for: Building permit required for new commercial construction and for commercial additions/remodels (including interior tenant-improvement build-outs) affecting structural or mechanical systems, per the adopted 2018 IBC; Plans must comply with the 2018 IBC and other applicable adopted I-Codes (IECC, IFGC, IMC, plumbing/electrical codes) as adopted by the City of Ammon; Commercial valuation shall be the contract price or the building valuation based on the Building Safety Journal square-foot cost table, whichever is greater; the Building Official may require documentation of the valuation to ensure accuracy; Building Code Plan Review fee for commercial projects is 65% of the Building Permit Fee (versus 10% for residential projects) — City Fee Resolution 2026-008, Section 1-A; A separate carve-out exists for 'repairs': fees for repair work (repairs of elements for which a permit is not specifically excluded) are the full building permit fee plus a flat 10% plan-check fee, with no Fire Department or Planning Department plan-check fee required — this 10% repair rate applies regardless of residential/commercial classification, but City Fee Resolution 2026-008 does not define where the line falls between a qualifying 'repair' and a full remodel/addition billed at the 65% commercial plan-review rate; this classification boundary is not published and was not otherwise confirmed; Planning Department approval must be obtained prior to obtaining a building permit; a Planning and Zoning Code Review fee of 10% of the Building Permit Fee is assessed and collected by the Building Department at time of application; A separate Commercial Site Plan Review fee of $600 (City Fee Resolution 2026-008, Section 2-A) applies to the Planning Department's site plan review process for commercial development — distinct from, and in addition to, the 10% Planning/Zoning Code Review fee embedded in the building permit application; Fire Department approval must be obtained prior to obtaining a building permit; the Fire Department plan-check fee is billed per the fee schedule adopted by the Bonneville County Fire District, not by the City directly — City Fee Resolution 2026-008, Section 3 states the City's own former Fire Department fee section is 'REPEALED' and directs applicants to 'refer to the fee schedule adopted by the Bonneville County Fire District'; All required plans, engineering documents, and materials for the entire scope of work must be submitted and approved before permit issuance — partial (e.g., foundation-only) permits are not issued, per the same City-wide policy that applies to residential; 100% of permit, plan-check, fire plan-check, and planning/zoning plan-check fees must be paid in full upon application submission; Deferred submittals (per IBC Section 107) are charged an additional plan review fee of 25% of the plan review fee, per each submittal; Submitted and tracked through the BluePrince online permitting portal — the same portal and general application flow used for residential permits; no commercial- or TI-specific application form is published separately.

No. The City of Ammon does not publish or maintain a distinct Tenant Improvement/TI permit product. Commercial interior remodels and build-outs are processed as a Commercial Building Permit — the same permit type used for new commercial construction — through the standard BluePrince application. Confirmed by checking the Building Department and Building Permits pages' full text and every linked PDF, plus testing several plausible commercial/TI-specific page and PDF URLs, all of which returned HTTP 404.

Commercial valuation is the contract price or the building valuation based on the Building Safety Journal square-foot cost table, whichever is greater, per City Fee Resolution 2026-008, Section 1-A. Residential valuation instead uses a flat published per-square-foot schedule (e.g., $120.00/sq ft for each finished floor).
