How Can I Legally Add an ADU on Long Island?
"Hey everyone, I’m looking into house hacking in an expensive market and want to explore adding an Accessory Dwelling Unit (ADU) to a property on Long Island, NY. My idea is to buy a 1-4 unit home with an FHA loan, live in one unit, and eventually convert a garage or other space into a legal ADU so I can rent out the main house.
I know Long Island has strict zoning laws, so I’m wondering:
- Which towns or villages allow ADUs? (Specifically looking at garage conversions or detached units.)
- What is the approval process like? Do I need special permits or zoning variances?
- Has anyone applied for the Plus-One ADU Grant? If so, what was the process like?
- Are there any local resources or professionals who specialize in ADU development on Long Island?
I appreciate any insights, personal experiences, or advice from anyone who has gone through this process!"
