STRs appear permitted but require standard rental property registration, Certificate of Continued Occupancy, zoning compliance, and NJ state tax collection. While no specific STR caps or restrictions were found, the lack of a dedicated STR ordinance creates moderate regulatory uncertainty requiring direct Building Department confirmation before investing.

Union Township sits in Union County in northern New Jersey, a densely populated suburban community of roughly 59,000 residents located in the greater New York metropolitan area. It lies about fifteen miles southwest of Manhattan, placing it within a comfortable commute of New York City while retaining a distinctly residential, tree-lined character. The township is best known as the home of Kean University and as a gateway to the Watchung Mountains, a chain of low wooded ridges that offers a surprising amount of green space in one of the country's most urbanized corridors.
Just minutes from the heart of Union, Watchung Reservation is the largest park in Union County, encompassing more than two thousand acres of forests, lakes, and ridgeline trails that draw hikers, joggers, and families year-round. The reservation also houses the Trailside Nature and Science Center, a small museum and environmental education facility popular with school groups and weekend visitors. The drive from most parts of Union to the main entrances is typically under fifteen minutes, making it a convenient escape for guests who want a taste of nature without leaving the suburbs.
To the east, the city of Newark borders Union directly, and it brings with it cultural and recreational sites like Branch Brook Park, famous for its sprawling collection of cherry blossom trees that bloom each April in a display often compared to the famous groves in Washington, D.C. The park, which stretches between Newark and Belleville, is roughly a ten-minute drive from Union and offers a free, scenic alternative to the busier city parks further north.
A short trip west brings visitors to South Mountain Reservation and the Turtle Back Zoo in West Orange, a family-friendly attraction set in a wooded park with a vintage carousel, a miniature train, and exhibits focused on animal conservation. From Union, the drive typically takes around twenty minutes, depending on traffic. Beyond these nearby draws, the township's position along the busy Northeast Corridor rail and highway network puts Manhattan, the Jersey Shore, and the wider tri-state region within easy reach for day trips, while a string of well-known outlet centers and shopping districts lies within a short drive.
Union's combination of suburban calm, walkable residential streets, and rapid access to both New York City and the natural escapes of northern New Jersey makes it a practical base for short-term rentals. Guests can spend a morning hiking the Watchung ridgeline, an afternoon browsing the shops and restaurants of nearby Newark or the Millburn-Short Hills area, and an evening watching the lights of Manhattan from across the Hudson, all without changing lodging. For travelers who want big-city access paired with the breathing room of a leafy commuter town, Union offers an appealing balance.
