Having worked with numerous Long Island homeowners, I’ve noticed increasing confusion about backyard tiny house regulations.
Long Island allows tiny homes as Accessory Dwelling Units (ADUs) in most areas, but regulations vary by township. Suffolk County generally has more lenient rules than Nassau County, with specific size and placement requirements.

Let me share what I’ve learned from helping clients navigate Long Island’s ADU regulations.
