Cass County permit authority
The first compliance decision is jurisdictional: identify the office with statutory authority over your parcel, then use its filing and inspection sequence to keep the project moving.
Jurisdictional status
State Fallback
This profile identifies a handoff outside the county’s ordinary structural permitting lane.
Required jurisdiction check
Confirm the controlling local or state authority before filing.
The record is marked State Fallback. That means the county profile should be treated as a routing brief: incorporated municipalities, a state building department, or a state fire marshal may control plan review, permits, and inspections. Contact the named agency below and verify the parcel’s jurisdiction before paying a fee or scheduling field work.

Project questions
Frequently asked questions for Cass County
Who handles permitting for this jurisdiction?
This record is marked State Fallback. Confirm whether a city, state agency, or other local authority controls the parcel before filing.
How should I begin an application?
Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact (218) 547-7241.
How long might review take?
N/A; no fixed county review timeline was published. Construction permits are valid for two years from approval.
How are inspections scheduled?
Submit a site inspection request through the county Applications / Permit Forms page; the 2026 fee schedule lists a $150 site-inspection request fee. Proposed structure corners must be visibly flagged when submitting. Contact Environmental Services at (218) 547-7241.
Which codes and exemptions should I review?
Cass County's official Comprehensive Plan states that there is no countywide building code. Environmental Services administers county land-use, zoning, shoreland, and environmental permits; verify building-code jurisdiction with the relevant municipality or state authority. Roof shingles, siding, windows, and interior remodels do not require a county permit when structural elements are not replaced or expanded, no bedrooms are added, and building use remains unchanged. Other work should be confirmed with Environmental Services.
