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.

Size restrictions

Penalties & bonding
No penalties or adjustments. Standard CUP/SUP process.
State-level permits & approvals
Iowa Utilities Board (IUB) generating certificate required for projects ≥25 MW (Iowa Code §478). Projects <25 MW: local CUP/SUP under county/township zoning governs. No statewide preemption of local ordinances — Iowa is a strong local-control state. County boards have full authority to restrict or deny solar below 25 MW threshold. Active local opposition movement in many agricultural counties; several moratoriums and restrictive ordinances enacted 2021–2024. IUB certificate does not override local zoning for sub-25 MW projects. MISO interconnection territory statewide.
