Start with jurisdiction and project scope
Before applying in Great Falls, confirm whether the property is within city limits or in unincorporated county territory. Describe the complete work to the office serving that parcel, including electrical, plumbing, structural, and site changes. Building, zoning, utility, and private HOA approvals can be separate.
Open the local official sources or prepare a project checklist.

Building Permit Exemptions
Great Falls building permit exemptions include small detached sheds, fences not more than six feet high, low retaining walls, and certain low, detached decks, but other local requirements may still apply.
Permit and scope questions
For Great Falls, ask the permit office to confirm the current area limit and the method used to measure it; the height or depth limit and the grade or reference point used for measurement; whether retained soil, adjacent slopes or supported loads require engineering; whether age, historic status or an overlay triggers additional review; the fence material, yard location and visibility restrictions; how structure use, attachment and utilities affect any accessory-building exemption; and whether attachment, a roof, stairs or required exit access changes the deck review before treating this project as exempt or permit-required.
Zoning and placement
Exempt work may still need zoning, parking, landscaping, right-of-way, or clear-vision review depending on the property and location.
Building and trade review
A Certificate of Occupancy or Certificate of Completion and all required inspections must be obtained before transferring water service billing information.
Discuss your project early when: Contact Great Falls before ordering materials or starting work to resolve the current area limit and the method used to measure it; the height or depth limit and the grade or reference point used for measurement; whether retained soil, adjacent slopes or supported loads require engineering; the fence material, yard location and visibility restrictions; how structure use, attachment and utilities affect any accessory-building exemption; and whether attachment, a roof, stairs or required exit access changes the deck review. Bring the proposed dimensions, location and scope so the answer is tied to the project.
