Livonia FAQ
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.
