Digital permit application gateway
Start with the issuing authority’s own submission lane. A complete application package, accurate valuation, and accessible inspection path are the fastest route through statutory plan review.
Recommended first click
Use the official digital gateway to submit plans, monitor review comments, pay required charges, and request inspections when the permit is issued. If the link is unavailable, use the agency website or phone number on the administrative profile to confirm the current lane.
Typical review lane
N/A; Missoula County’s reviewed Building Division and permit-guide pages provide application and inspection instructions but no single typical plan-review timeline.
Treat this as a planning signal, not a guaranteed approval date. Completeness, corrections, resubmittals, and agency workload control the actual clock.
Verify the parcel is inside this agency’s service area and note whether a city, state, fire marshal, septic authority, or utility district also has approval authority.
Prepare legible plans, site information, project valuation, ownership authorization, contractor information, and any energy, floodplain, zoning, or utility documentation the issuing office requires.
Keep the permit number, approved plan set, correction comments, fee receipts, and inspection results together. Those records establish the compliance trail for the next trade.
Application documents
Before submission, call (406) 258-3701 (Missoula County Building Division); (406) 258-4642 (Planning, Development & Sustainability) if the project involves a change of occupancy, structural alteration, accessory structure, demolition, or work near a regulated environmental feature.
Source trail
Use these direct agency or licensing links to confirm current instructions before you file, pay, or schedule work. External pages control if their information differs from this directory.

Missoula County’s certified county building program applies Montana-adopted and amended building codes outside Missoula city limits, including the current 2021 International Building Code, 2021 International Residential Code, 2021 International Existing Building Code, 2021 International Mechanical Code, 2021 International Fuel Gas Code, 2021 International Energy Conservation Code, 2021 Uniform Plumbing Code, 2020 National Electrical Code, 2021 International Swimming Pool and Spa Code, and 2021 Wildland-Urban Interface Code, as amended by Montana rules. Missoula city limits use the city’s separate building division. Missoula County’s current permit guidance states that detached storage structures such as garages, sheds, or pole barns may not require a building permit under the June 4, 2026 update, but they remain subject to applicable land-use, zoning, floodplain, shoreline, and other permits. Other exemptions must be confirmed with the Building Division; agricultural, utility, site, and manufactured-home work may trigger separate approvals.
What makes an application complete
Before you click submit, make sure the drawings agree with the site plan, project description, valuation, ownership authorization, and contractor information. If the work changes structure, occupancy, drainage, fire protection, energy performance, or utility demand, describe that scope plainly. Ambiguous narratives create correction cycles and delay the field schedule.
Save the confirmation number, payment receipt, uploaded plan set, and every correction comment. Those records are the backbone of a defensible compliance file when multiple trades or agencies share responsibility.
Submission quality check
Site: address, parcel, access, setbacks, and existing conditions are consistent.
Scope: structural, mechanical, plumbing, electrical, fire, and energy work is identified.
Closeout: inspection contacts and the final approval path are understood before work begins.
