Permitting process
Local permitting pathway
Conditional Use Permit (CUP) or Special Use Permit (SUP) in Agricultural (A) or Rural zoning district; administered by county planning board or zoning board of adjustment. Process varies by county; most counties lack solar-specific ordinance.
Setbacks & buffers
No Montana state-mandated solar setback floor for sub-250 MW facilities. Standard agricultural district setbacks apply (typically ≥25–50 ft from property line, ≥50 ft from road ROW) where no county solar ordinance exists. County-specific setbacks may apply if local ordinance adopted. — NOTE: the distances above are a STATE-level fallback, not a figure read from this county's own ordinance. We hold siting-rule records for this county which may include a stricter local limit we have not yet extracted. Verify against the county's own ordinance before relying on these.
Spacing requirements
None codified.
Size restrictions
None codified; managed via CUP/SUP conditions
Penalties & bonding
Total: -5 | Permissive ordinance flag: -5
State-level permits & approvals
Sub-250 MW: county-level CUP or SUP in agricultural/rural zone; county planning board or BZA approval; process and timelines vary by county (typically 60–180 days). Facilities ≥250 MW nameplate: Montana Major Facility Siting Act (MCA 75-20) — requires BER siting certificate; full environmental review. MPSC regulates net metering interconnection for qualifying facilities. No state preemption statute; counties retain full authority for sub-250 MW.
