Islip Town Code Chapter 68 permits home occupations as accessory uses in residential districts provided the use is clearly incidental to the dwelling, conducted entirely within the home by residents, with no external evidence of the business and no non-resident employees.
Under Islip zoning, a home occupation cannot occupy more than a limited percentage of the dwelling floor area, cannot generate customer traffic beyond residential norms, and cannot include outdoor storage, signage, or commercial vehicles parked on site. Uses typically prohibited as home occupations include auto repair, kennels, restaurants, and retail sales. Operators must obtain a NY State Certificate of Authority for sales tax if selling tangible goods, and a Suffolk County consumer affairs license if the activity falls within regulated trades such as home improvement contracting.
Zoning violations are enforced by Islip Division of Code Enforcement with citations, fines, and potential cease-and-desist orders. Repeat violations may escalate to Suffolk County District Court.
