Setback basis: 30 or 60-year recession
Permit issuer: EGLE

Full Breakdown

MCL 324.32301 through 324.32315 authorize EGLE to designate high-risk erosion areas (HRAs), flood-risk areas, and environmental areas along the Great Lakes shoreline. Within HRAs, a state setback permit is required for any permanent structure based on the average annual recession rate. Local ordinances must conform to or be more restrictive than state setbacks; less restrictive rules are preempted.

Violations & Penalties

Building without a state setback permit can result in removal orders and civil fines up to $10,000 per violation.

Frequently Asked Questions

How do I know if my property is in a high-risk erosion area?

EGLE publishes county-level HRA maps online. Lots in HRAs require a state-issued setback permit before any new permanent construction or substantial reconstruction.

Can I add a deck without a state permit?

Permanent additions, including attached decks within the HRA setback, require an EGLE permit. Movable, non-permanent structures may be exempt; verify with EGLE before building.
