ADU rules in Wayne County, town by town
New York has no statewide ADU law, so each town, village and city writes its own rules. We’ve checked 12 municipal codes in Wayne County so far. 1 of them describes a current way to approve an ADU or accessory apartment.
Don’t see your town? We haven’t checked its code yet. Start with the guide to checking local rules, or send us a question.
A village has its own zoning, separate from the town around it, and a ZIP code can cover both. Check which government is on your property tax bill. This table is a screening guide, not a permit answer: your zoning district and your lot decide. Codes change, so confirm with the code office before you spend money.
