Zoning & Home Occupation Permits
The Town of Islip permits a home occupation only as an accessory office use inside a single-family residence in a single-family residential district, conducted by the residents. The use cannot change the character of the building as a residence or the site as a residential plot. It may employ at most one nonresident, may not occupy more than 15% of the home's gross floor area (25% with a New York State variance) and never more than 500 square feet.
Home occupations allowed as accessory office use only
Some RestrictionsTown of Islip Code Sec. 68-3 (Zoning, definition of Home Occupation)
HOME OCCUPATION - An office activity conducted within a single-family residence in a single-family residential district by the residents thereof as an accessory use within the main dwelling that does not change the character of the building as a residence or the character of the site as a residential plot.
Signage Rules
Islip strictly limits signage for home businesses. A 'home occupation sign' is defined as one that identifies only the name and/or occupation of the practitioner conducting a permitted home occupation in a dwelling. All signs are regulated under Chapter 68 (Zoning) Article XXIX, and signage in residential districts is tightly restricted, so advertising-style or oversized business signs are not allowed at a home.
Home occupation signs limited to a name nameplate
Heavy RestrictionsTown of Islip Code Sec. 68-3 (Zoning, definition of Home Occupation Sign)
HOME OCCUPATION SIGN - A sign which identifies only the name and/or occupation of a practitioner or one conducting a permitted home occupation in a dwelling.
Customer Traffic Restrictions
Because a home occupation cannot change the residential character of the property, Islip controls how parking for the business is handled. Town Code Section 68-3 requires that parking for a home occupation use be installed, landbanked, or screened from view at the direction of the Commissioner of Planning and Development. This keeps customer or employee parking from giving the lot a commercial appearance.
Home occupation parking must be screened from view
Some RestrictionsTown of Islip Code Sec. 68-3 (Zoning, home occupation parking)
Parking for the home occupation use shall be installed, landbanked or screened from view pursuant to the direction of the Commissioner of Planning and Development or the Commissioner's designee.
Cottage Food Operations
Islip's code does not separately address selling home-baked or canned foods, so New York State's Home Processor exemption applies. Under New York Agriculture and Markets Law Section 251-z-4, certain low-risk foods made in a home kitchen can be sold without a full food-processing license once the operation is registered with the state Department of Agriculture and Markets. The home kitchen itself must still satisfy Islip's zoning home occupation limits.

Some RestrictionsNY Agriculture and Markets Law Sec. 251-z-4 (Exemptions)
In addition to the exemptions specified in subdivision three of section two hundred fifty-one-z-two, the commissioner may, if he determines that the protection of the consumers of the state as a whole will not be impaired by such action, provide by regulation for exemption from licensing of small food processing establishments.
Home Daycare
Islip allows residential day care as an accessory use in its residential districts under Town Code § 68-48A(1)(l), but only if the provider is licensed and registered by the Long Island regional office of the New York State Office of Children and Family Services and meets state building and health code requirements.
