Whitefish, Montana Building Permit Guide

Whitefish runs a full building program inside its city limits: the Planning & Building Department at 418 E 2nd Street issues building permits and its own electrical, plumbing and mechanical permits, and houses need a permit here just as commercial buildings do. Applications go in through the Citizen Portal or by email. The City bases permit fees on a percentage of the estimated project cost and takes a plan review deposit at submittal, $200 for residential and $500 for commercial work, which is deducted from the permit fee. Inspections are booked at 406-863-2414 with at least 24 hours’ notice.

What needs a permit in Whitefish?

The City requires permits for all new construction within Whitefish city limits and lists the common cases. The Building Department asks owners to call 406-863-2410 before starting if they are unsure.

The City Code applies the building codes to every building in the City’s enforcement area, including houses with fewer than five units, farm buildings and private garages. A structure small enough to skip the building permit must still meet the zoning setbacks.

Code editions: the City’s permit page tells designers to draw to the 2021 IBC, IRC, IECC, IEBC, IMC, IFGC, UPC, ISPSC and IWUIC and the 2020 NEC, and its March 2026 applications still cite the 2021 wildland-urban interface code. The State of Montana moved to the 2024 editions of those codes and the 2023 NEC on September 26, 2026. Under the City Code, the City Manager adopts new State editions by administrative order within 30 days of the State’s notice to the City, and the earlier editions stay in force until that order is issued. State rules give a certified city 90 days from the notice to bring its codes into line.

Who issues permits in Whitefish?

The Planning & Building Department is at City Hall. Tad Lisowski is the Chief Building Official. The State lists Whitefish as certified for building, plumbing, electrical, mechanical, pool and wildland-urban interface codes inside its city limits, so no State trade permits are needed for work in town.

City permits stop at the city limits. Land outside them is in Flathead County, which has no building department: the State Building Codes Program is the building-code authority there, and the County handles zoning, lakeshore, floodplain and septic matters. The City’s permit page also carries a notice about Columbia Falls: projects inside Columbia Falls city limits cannot use the Whitefish portal, and their applications and fees go to Columbia Falls City Hall.

Permit types and online filing

The Citizen Portal lets you submit applications, follow their status and pay invoices, including application deposits and building permit fees. Applications can also be emailed to the Building Department. One application is needed for each independent structure, and the City will not treat an application as complete until all documents and fees are in. The City has warned that it never emails applicants a request to wire funds.

• Residential Building Permit Application and Commercial Building Permit Application, both revised March 2, 2026.
• Trade Permit Application for electrical, plumbing and mechanical work, listing the contractor’s City business licence number and State licence.
• Building Permit Application Affidavit, signed by the applicant; a representative needs an authorization letter from the owner.
• Plumbing Fixture Form (revised October 2025), required whenever the plumbing fixture count changes, because Public Works uses it to calculate impact fees.
• Public Tree Impact Form, required when excavation or construction will take place within 50 feet of a public tree.
• Fence Permit and Building Permit Extension request.

A building permit stays valid as long as the project keeps progressing. If work is delayed or stops for 180 days or more, an extension has to be requested or the permit may be cancelled.

Whitefish permit fees

The City states that building permit fees are based on a percentage of the estimated cost of the project, and invoices are paid through the Citizen Portal. The fixed amounts on its forms are these:

Under the City Code, 29% of the building permit fee is collected as a Fire Prevention Program fee, and the building permit fee is reduced by the same amount, so the split does not raise the total. Impact fees are separate: the code assesses them for water, wastewater, police and fire when a complete building permit application is submitted, and they are paid when the permit is issued. Residential additions of 500 square feet or less, fences, pools, signs and demolitions are among the exemptions. The four fee types are those in City Code 10-2-1 as amended by Ordinance 26-09 on August 3, 2026; the City’s Impact Fees web page lists water, wastewater, stormwater, paved trails, a park maintenance building, an emergency services building and City Hall.

After-the-fact lakeshore permits cost four times the normal fee, and after-the-fact sign permits cost double.

Electrical, plumbing and mechanical permits

Whitefish issues trade permits itself. The Trade Permit Application asks for the contractor’s company details, City business licence number and State of Montana licence, the project address, whether the job is commercial or residential, a description of the work and its valuation. The City inspects rough electrical, rough mechanical and rough plumbing, underslab plumbing and heating, and final mechanical work; a final electrical inspection is listed for services over 400 amps and for commercial jobs.

A final fire inspection follows once the fire tests are complete. The fire inspections on the City’s list are the underslab flush test, sprinkler visual, dry system air test, hydrostatic test, alarm and flow test, emergency and exit light test and hood test. New construction and additions must include a fire risk assessment under the 2021 wildland-urban interface code.

Application documents and plan review

Plans have to be detailed enough to build from: site plan, floor plan for each level, exterior elevations, stair section, foundation plan, framing details and a wall section from footing to ridge. They must note the proper snow load, Seismic Zone D1 and a 110 mph wind speed, and truss design criteria from the manufacturer must be in before the permit is issued. Residential energy compliance is shown prescriptively or with REScheck.

How to apply: 7-step Whitefish process

Whitefish inspections

Inspection appointments need a minimum of 24 hours’ notice, by phone at 406-863-2414 or by email to the Building Department, and the project address has to be given with the request. The City’s Required Inspections List (revised September 1, 2025) runs in this order:

• Sonotubes, piers, columns and footings, with a string line or letter of survey
• Walls, foundation waterproofing, underslab heating and plumbing, and the concrete slab
• Shear wall nailing and rough framing
• Rough electrical, mechanical and plumbing, and the pre-final water inspection
• Insulation and drywall nailing
• Final mechanical, final electrical, final fire, final planning, final Public Works and final water
• Final building inspection, once every earlier inspection has passed

Townhomes have extra party-wall drywall inspections. A Certificate of Occupancy and permanent water and sewer service are issued only when all City code requirements are met, including paving, landscaping, required permits and payment of fees; the City may ask for a bond or letter of credit for work that cannot be finished right away. The City also publishes cold-weather concrete heating requirements.

Local Whitefish details that matter

Lakeshore: a Lakeshore Construction Permit is required before any work in Whitefish Lake or Lost Loon Lake or within the 20-foot lakeshore protection zone. That includes docks and shore stations, retaining walls, patios and stairways, excavation and fill, riprap, utility lines and removing native vegetation over 3 inches in diameter.

Architectural review: commercial, industrial and public buildings and triplex, fourplex and multi-family projects are reviewed against the Architectural Review Standards before the building permit application, as are additions, facade changes and repainting of those buildings. City Code 11-3-3(B) exempts detached single-family homes and duplexes, and the City’s Architectural Review page repeats that. The Project Fee Schedule of October 18, 2021 nevertheless carries a $330 row for “duplex and triplex” projects, and the building permit application revised March 2, 2026 asks for an approval letter on duplex, townhome and multi-family projects, so owners of a two-unit building should settle the point with the Planning & Building Department at 406-863-2410 before applying. The Architectural Review page says the zoning administrator reviews and approves applications and that no committee review is required.

Water quality protection: projects within 200 feet of a lake, wetland, stream or river file the City’s Water Quality Protection checklist, and no terrain may be disturbed for development until a site plan under a building permit is approved.

Public trees: the Parks Department reviews the Public Tree Impact Form, and permits are not issued until its conditions are met.

Fences: 48 inches is the limit in a front yard and 6.5 feet along rear and side yards; barbed wire is allowed only in the WA, WCR and WSR zones.

Review times: the City puts a conditional use permit at about 3 months from application to decision and a zoning variance at about 2 months.

Montana building code

Montana adopts one building code, based on the 2024 International Codes from 26 September 2026; a certified local program or the state Building Codes Program enforces it, and the state code does not reach houses of fewer than five units, farm and ranch buildings or private garages unless a local government has made it apply to them.
