STR Regulations for Islip, New York

Overview: Are Short-Term Rentals Allowed in Islip, New York?

No, short-term rentals are explicitly banned in the Town of Islip.

According to a 2015 news report from News 12 Long Island, the Islip Town Board unanimously voted to make it illegal for homeowners to offer short-term rentals on their properties. The ordinance bans rentals for less than 14 nights. There is an important exception: properties on Fire Island are excluded from this ban.

Therefore, while operating a traditional STR (e.g., renting out your home on Airbnb for less than 14 nights) is illegal on the mainland part of Islip, it may be permitted on Fire Island, which is a barrier island within the town's jurisdiction but governed separately for many purposes.


How to Start a Short-Term Rental Business in this Market

For the mainland part of Islip, the short and direct answer is: You cannot legally start a traditional STR business.

  • The Ban: The town code prohibits renting a property for fewer than 14 nights. Any advertisement for, or operation of, such a rental would be illegal.
  • The Exception (Fire Island): If your property is on Fire Island, you must comply with the specific regulations of the Fire Island community (e.g., Fire Island Pines, Ocean Beach, etc.) as these are separate municipal entities for many zoning and rental matters.
  • Alternative: Long-Term Rental or ADU: An investor's only viable options for generating rental income on the mainland are:
    1. Long-Term Rentals: Renting the property for periods of 14 nights or more, which is compliant with town code.
    2. Accessory Dwelling Unit (ADU): The town has a program (administered by the Long Island Housing Partnership) to help homeowners create legal ADUs. However, a critical program requirement is that the ADU must be occupied by a permanent tenant; short-term rentals, including vacation and seasonal rentals, are not permitted.

Required Documents, Permits, Licenses, and Guidelines

For a Traditional STR (Not Permitted on Mainland):

  • Status: Not allowed on the mainland of Islip. Therefore, no legal path exists to obtain a permit or license for this purpose.
  • Consultation: For definitive confirmation and to explore any possible variance or unique exceptions, contact the Islip Town Attorney's office (see Contact Information section).

For an Accessory Dwelling Unit (ADU):

If you are a homeowner interested in creating an ADU (which must be used for long-term tenancy), the Plus One Accessory Apartment Program provides significant financial assistance. The required documentation is extensive and must be submitted to the Long Island Housing Partnership (LIHP).

Key Eligibility & Requirements (from the 2024 Program Guidelines):

  • Applicant: Must be the owner and primary resident of the property for at least one year, current on all mortgage and tax payments, and have household income at or below 100% of the Area Median Income (AMI) for Nassau/Suffolk Counties.
  • Property: Must be a pre-existing single-family residence. It must comply with all municipal zoning codes (lot size, ADU size, design requirements) and health department requirements.
  • Compliance: The owner must obtain all necessary building permits and certificates of occupancy through the Town of Islip's standard process. Municipal code takes precedence over program guidelines.
  • Covenant: The property is subject to a 10-year restrictive covenant. During this period:
    • The ADU must be occupied by a permanent tenant year-round.
    • Short-term rentals are explicitly prohibited.
    • The owner must occupy the primary residence.

Specific Regulations for Short-Term Rentals

  • Town of Islip (Mainland): BANNED for rentals fewer than 14 nights.
  • Fire Island (within Town of Islip jurisdiction): Excluded from the ban. Properties here are subject to the regulations of the specific Fire Island village or community.
  • Accessory Dwelling Units (ADUs): STRs are prohibited by the covenant governing the ADU grant program. ADUs must be used for permanent tenancy only.

Overview of Islip

Islip is a sprawling town on the south shore of Long Island in Suffolk County, New York, with an approximate population of around 335,000 residents spread across more than a dozen villages and hamlets. It sits about 50 miles east of New York City and roughly 30 miles west of the Hamptons, giving it a useful perch between the metropolitan core and the resort communities of the East End. The town has a distinctly suburban Long Island character, a mix of leafy residential streets, working waterfronts, and protected bayfront marshland facing the Great South Bay. Islip is best known as home to Long Island MacArthur Airport and as a gateway to Fire Island, with ferries from its southern communities connecting travelers to one of the East Coast's most distinctive barrier-island destinations.

Just minutes from the heart of Islip, Heckscher State Park offers more than 1,600 acres of waterfront green space on the eastern edge of the Great South Bay in East Islip. The park features a broad sandy beach, miles of marked hiking and biking trails, campgrounds, and a large picnic area shaded by mature oaks, making it a year-round draw for swimming in summer and leaf-peeping in fall. It is roughly a 10-minute drive from the town center.

For travelers interested in Long Island's quieter natural side, Bayard Cutting Arboretum State Park sits along the Connetquot River in the hamlet of Great River, within the Town of Islip. The roughly 690-acre property includes formal gardens, walking trails through old-growth oak and pine, and a late-Victorian Tudor-style manor house. It is about a 15-minute drive from Islip's center and offers a calmer alternative to the estate tours of the North Shore and the Hamptons.

In West Sayville, the Long Island Maritime Museum celebrates the region's seafaring past with exhibits on South Shore shipbuilding, baymen culture, and oyster harvesting, along with a collection of historic vessels docked just outside. A short walk from the museum, the West Sayville waterfront offers sunset views over the bay and a small working marina. The museum is approximately 20 minutes from downtown Islip.

The hamlet of Bay Shore gives the town a small but lively downtown along Main Street and Montauk Highway, with a row of restaurants, coffee shops, and antique stores. From the Bay Shore Marina, seasonal ferries carry visitors south past the barrier beach to Fire Island communities such as Ocean Beach and Cherry Grove. The downtown and ferry terminal sit about 15 minutes from the geographic center of Islip.

Islip's combination of suburban accessibility, bayfront parks, and proximity to both New York City and the East End makes it a strong base for short-term rentals. Guests can spend the morning on Fire Island, the afternoon wandering a riverside arboretum, and the evening dining in Bay Shore, all while staying within a short drive of Long Island MacArthur Airport and the rest of Long Island.
