Building permits for unincorporated Kootenai County are issued by the Building Division of Kootenai County Community Development, 451 Government Way, Coeur d’Alene, 208-446-1040, open Monday to Friday, 7 a.m. to 4 p.m. The county issues building, mechanical, manufactured home setting and site disturbance permits; plumbing and electrical permits and inspections come from the state Division of Occupational and Professional Licenses (DOPL). Kootenai is Idaho’s third most populous county, with 191,864 people in the Census Bureau’s 2025 estimate.
This guide covers the department and how to reach it, the local conditions that shape a filing here, what permits cost and who may pull them, and how inspections are booked. Rules that apply everywhere in Idaho are summarized in each section, with a link to the full statewide explanation.
This guide covers unincorporated Kootenai County. The county’s Building Division has no jurisdiction inside city limits, so for a parcel in Coeur d’Alene, Post Falls, Hayden, Rathdrum or another city, go to the city.
The county publishes a snow load zone map. Zone A requires a minimum flat-roof snow load of 40 psf, Zone B 50 psf and Zone C 60 psf, with the IRC’s prescriptive requirements. In Zone D an Idaho licensed engineer must determine the design snow load for the parcel, from the ground snow load calculated under “Ground and Roof Snow Loads for Idaho”, and design the building to it. Check the parcel’s zone on the county map before design.
What requires a building permit in Kootenai County?
Where a city or county enforces building codes, a permit is required under its ordinance before construction, alteration or repair (Idaho Code 39-4111).

Confirm scope with the department before work starts rather than after.
Which code edition applies
Kootenai County enforces the 2018 International Building, Residential, Fire, Energy Conservation, Mechanical, Fuel Gas and Existing Building Codes, with local amendments in county building Ordinance 608. Its other published design criteria are seismic design category C, a 115 mph IRC wind speed, a soil bearing pressure of 1,500 psf and a 24-inch frost depth.
Idaho’s building codes are set statewide and enforced by the cities and counties that run a building program: the 2018 International Building Code and the Idaho Residential Code (based on the 2018 IRC), the 2018 Idaho Energy Conservation Code, the 2023 National Electrical Code, and a state plumbing code based on the 2015 Uniform Plumbing Code rather than the International Plumbing Code.

Who handles permitting in Kootenai County?
The county permits unincorporated territory and has no jurisdiction inside city limits. Only four cities have an adopted area of impact: Coeur d’Alene, Hayden, Post Falls and Rathdrum; a map for Stateline is under consideration. The county adopted new area of impact ordinances in December 2025, and the Coeur d’Alene and Post Falls areas are now the land within one-eighth of a mile (660 feet) of the city limits. An area of impact is unincorporated land, so the county issues the building permit there, and under Idaho Code 67-6526 the county’s comprehensive plan and zoning and subdivision ordinances apply in it.

Grading, excavating and storm drainage or run-off control need a county site disturbance permit before the work starts, separate from the building permit.
In 2025, building permits issued in unincorporated Kootenai County authorized 341 new privately owned housing units, all of them single-family homes, according to the U.S. Census Bureau Building Permits Survey.
Electrical, plumbing and HVAC permits come from the state’s Division of Occupational and Professional Licenses unless the city or county runs its own program by ordinance. Septic systems need a health district installation permit, a highway district controls the roads in its system, and since 2024 the county’s zoning applies in a city’s area of impact. Who issues permits in Idaho
Permit types
Residential permits
The county issues residential permits for single and multi-family dwellings, garages, decks, pole barns, residential storage buildings over 200 square feet, fences over seven feet tall and re-roofing. Setting a mobile home on real property also needs a permit, and septic and water quality questions go to Panhandle Health District.
Snow, seismic and wildland exposure
Design loads are site-specific. Idaho law lets each city and county set the design criteria in Section R301 of the Idaho Residential Code, including ground snow load, by local ordinance (Idaho Code 39-4116), so design to the figure the issuing department sets for the site.
The seismic design category is also set by the site under the adopted codes, and wildland-urban interface rules apply where the city, county or fire district has adopted them. Confirm the design criteria for the parcel with Kootenai County Community Development at the start of design.
Commercial permits
The county issues permits for commercial structures and for commercial storage buildings over 120 square feet. It advises applicants to contact Panhandle Health District and the relevant fire and highway districts, which may have their own requirements and fees.

How to apply for a Kootenai County building permit
Zones A to C set minimum loads; in Zone D an engineer determines the figure.
A 25-foot shoreline management area applies, and docks need an IDL encroachment permit.
The county refers site access questions to the districts with jurisdiction.
Grading, excavation and drainage work need it before they start.
Inside the area of impact the county’s zoning applies (Idaho Code 67-6526).
Contractors register with the state; electricians, plumbers and HVAC contractors hold state licences.
Under Section 105.5 of the adopted codes a permit becomes invalid if work does not start within 180 days or stops for 180 days; check whether the local ordinance amends that. How long Idaho permits last
Inspections in Kootenai County
The local department sets the inspection stages; ask for its list when the permit is issued. Plumbing and electrical inspections are done by state inspectors (Idaho DOPL inspection line, 208-332-4700), and the county publishes its own final-inspection scheduling requirements for plumbing and electrical permits.

Do not cover work before the required inspection has been approved. The approved construction documents must be kept at the site (IBC 107.3.1, IRC R106.3.1).
Kootenai County permit search and official resources
Permit records sit with the authority that issued them, which in Idaho means the record may be split. A property can have records with several bodies: the building department, the state where it issued trade permits, a highway district for access and the health district for a septic system. If you are buying, refinancing or renovating, ask Kootenai County Community Development what it holds for the parcel, and ask separately about the septic and access records where those apply.
Where a property has been annexed, permits issued before annexation may still be held by the county.
Confirm the code edition against Idaho’s adopted list. Idaho enforces the 2018 International Building Code and the Idaho Residential Code (based on the 2018 IRC), the 2023 National Electrical Code and a plumbing code based on the 2015 Uniform Plumbing Code. A new edition takes effect on January 1 after the Idaho Building Code Board adopts it (Idaho Code 39-4109), so check the codes and local amendments in force on your filing date.

Frequently asked questions
What snow load should I design to?
Find the parcel’s zone on the county snow load map. Zones A, B and C require minimum flat-roof snow loads of 40, 50 and 60 psf; in Zone D an Idaho licensed engineer determines the parcel’s design snow load.
Inspections are where schedules slip.
Get a free quote →What applies on a lakeshore parcel?
A 25-foot shoreline management area, measured in slope distance landward of the ordinary high water mark (Kootenai County Code 8.7.111). For a dock, marina or shoreline stabilization on a navigable lake, an encroachment permit from the Idaho Department of Lands is required. Both are separate from the building permit.
What does wildland interface mean for my project?
The county’s 2021 Community Wildfire Protection Plan places virtually all of the county, except the cities’ downtown cores, in the wildland-urban interface. The county refers site access questions to the highway and fire districts with jurisdiction.
What does the health district do?
Installing, modifying, repairing or expanding a septic system needs an installation permit, which the public health district finalizes (IDAPA 58.01.03).
Which code edition applies in Idaho?
Idaho enforces the 2018 International Building Code with Idaho amendments and the 2021 IBC mass timber provisions, the Idaho Residential Code based on the 2018 IRC, the 2018 Idaho Energy Conservation Code and the 2023 National Electrical Code (IDAPA 24.39.30; Idaho Code 54-1001).
Does the International Plumbing Code apply?
No. Idaho has adopted the Idaho State Plumbing Code, based on the 2015 Uniform Plumbing Code with Idaho amendments (IDAPA 24.39.20).
