Start with jurisdiction and project scope
Before applying in Billings, 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.

Residential Building Permits
Billings requires building permits for many private-property construction projects including roofing, siding, decks, retaining walls, parking lots, and taller fences.
Permit and scope questions
For Billings, ask the permit office to confirm 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; whether attachment, a roof, stairs or required exit access changes the deck review; and which roof repairs, material changes or structural work require a permit before treating this project as exempt or permit-required.
Zoning and placement
Planning review can be needed for fences, setbacks, lot coverage, and site-plan issues even when a project is not a full building-plan submittal.
Building and trade review
Building permit applications are submitted through the GoPost online portal, while residential roofing, siding, windows, and doors may be submitted by email.
Discuss your project early when: Contact Billings before ordering materials or starting work to resolve whether retained soil, adjacent slopes or supported loads require engineering; the fence material, yard location and visibility restrictions; whether attachment, a roof, stairs or required exit access changes the deck review; which roof repairs, material changes or structural work require a permit; and the setbacks, easements and public-space constraints for the parcel. Bring the proposed dimensions, location and scope so the answer is tied to the project.
