Commercial Building Permit (New Construction, Additions, Remodels & Tenant Improvements) in Preston, Idaho

Preston requires a commercial building permit (new construction, additions, remodels & tenant improvements) for: Land Survey of the lot prepared by an Idaho licensed engineer or land surveyor (a stamped plat map for a platted subdivision is acceptable if the lot is clearly identified) — the same document checklist used for residential projects, per the Building Permit Application Instructions; Copy of deed showing ownership and legal description; Detailed Site Plan showing lot dimensions, proposed and existing structures, setbacks, easements, finish contours/drainage, floor elevation, street/sewer elevations, utility line locations, use of each building, and a North arrow; Complete Building Plans meeting current building code specifications, reviewed by the city Building Inspector; no specific adopted code edition (such as a numbered IBC year) is named anywhere in the Building Permit Application Instructions, the Building Department's webpages, or Idaho DOPL's Building Code page — Idaho's statewide code-adoption framework governs absent a city-specific figure; Cut Permit (Encroachment/Cut Permit) if the project requires cutting a city street, including a licensed contractor to dig and locate city services; Current Preston City Business License for any contractor or other non-owner service provider working on the project; Preston has no distinct commercial-building-permit or tenant-improvement/TI permit product: commercial new construction, additions, and remodels use this same Building Permit application, document checklist, and CloudPermit portal used for residential work; Resolution #178's flat Building Permit Application Fee sub-categories (Single/Multi Family Dwelling, Additions, Accessory Building) do not include a Commercial line item; contact the Building Department for the applicable fee before budgeting a commercial project; A sewer or water connection larger than a standard 1-inch service, or a fire-suppression water line for a sprinkler system, is billed on Resolution #178's separate utility connection-fee schedule in addition to the Building Permit fee itself; Per Idaho Code 39-4117 (statewide, added 2025): for a commercial building permit application, Preston must, within 20 business days of receipt, provide written notice if the application is incomplete, and must issue a written completeness determination within 20 business days of a submission or revised submission — 20 business days for commercial versus 10 business days for residential. A completeness determination is not approval; it only authorizes the application to proceed to plan review.; No fire-district or state fire marshal plan-review requirement for privately owned commercial construction was found: the Idaho State Fire Marshal's Plan Reviews program is scoped to state-owned and state-leased buildings, and the Franklin County Fire District's own published materials cover burn permits and emergency response rather than a building-plan-review process — confirm directly with the Building Department and the Franklin County Fire District whether either applies to a given project. If your project isn't listed, confirm with City of Preston Building Department at (208) 852-1817 before starting work.

The Building Permit itself is set by the city inspector based on the project's valuation, the same as for residential work — no flat percentage is published. Resolution #178's flat Building Permit Application Fee, however, lists only Single/Multi Family Dwelling ($150.00), Additions ($50.00), and Accessory Building ($25.00) categories, with no Commercial line item; contact the Building Department for a quote on that fee. Separately, a commercial project needing a sewer or water connection larger than a standard 1-inch residential service, or a fire-suppression water line, is billed on Resolution #178's utility connection-fee schedule ($9,000.00 to $36,000.00 depending on size and type).

Preston's published plan-review target for a commercial building permit (new construction, additions, remodels & tenant improvements) is 30+ business days.

You'll need: Building Permit Application Instructions; Land Survey or stamped Plat Map; Copy of Deed; Site Plan (PDF); Building Plans (PDF); Preston City Business License. Depending on your project, Preston may also ask for: Encroachment/Cut Permit. See the required-documents checklist on this page for details on each.

Apply through City of Preston Building Department at 70 West Oneida, Preston, ID 83263. Phone: (208) 852-1817, email: curtf@prestonid.us. Office hours: Monday–Friday, 8:00 AM to 5:00 PM, per prestonidaho.net main contact info. Building Inspector: Curt Fuller (208-540-0417, curtf@prestonid.us). Permit Administrator: Shawn Oliverson (208-852-1817, shawno@prestonid.us), per the city's Building Department page and Employee Directory. Note: the city's Employee Directory lists Shawn Oliverson's title as 'Director of City Planning and Land Use' rather than 'Permit Administrator' — both titles appear on different city-published pages and are reported here without resolving the discrepancy. No separate 'City Engineer' position appears in the Employee Directory despite being referenced in the Building Permit Application Instructions document; Public Works Director is Scott Montgomery..

Preston's own published materials — the Building Permit Application Instructions, the Building Department's webpages, Resolution #178, and Idaho DOPL's Building Code page — do not name a specific adopted code edition or year. Idaho's statewide code-adoption framework, administered by the Idaho Building Code Board, governs in the absence of a city-specific figure; contact the Building Department or Idaho DOPL to confirm the edition currently in force for a specific project.

No. Preston does not publish a distinct commercial-building-permit or TI-permit product. Commercial new construction, additions, and remodel/tenant-improvement work use the same Building Permit application, the same document checklist (Land Survey, Deed, Site Plan, Building Plans, and a Cut Permit if applicable), and the same CloudPermit online system as residential projects.

No published requirement was found. The Idaho State Fire Marshal's Plan Reviews program is limited to state-owned and state-leased buildings, and the Franklin County Fire District's own published materials describe burn permits and emergency response services rather than a commercial building-plan-review process. Confirm directly with the Building Department and the Franklin County Fire District whether either reviews a given commercial project.
