Islip permits garage sales as temporary residential activity but regulates frequency and signage under Chapter 68 and zoning rules. Typically limited to 2-3 sales per year per address with each sale not exceeding 3 consecutive days.
Garage sales are considered accessory residential use. The Town of Islip limits frequency to prevent de facto retail operations in residential zones. Sales must occur on the property of the homeowner, not on public right-of-way. Items sold must be personal household goods, not commercial inventory. Hours generally 8 AM to sunset. Signs governed by Chapter 68 signage provisions with prompt removal required.
Exceeding frequency or duration: 100-500 dollars. Selling commercial merchandise may trigger zoning enforcement for unlicensed business.
