Long Hill Township's housing is largely suburban single-family stock built around its four villages. Millington, Stirling, Gillette, and Meyersville each contain established neighborhoods of colonials, ranches, and split-levels from the mid-twentieth century, alongside some older village homes near the rail stations and newer infill construction. The early Homestead Park subdivision, developed in the 1920s, is the township's first planned neighborhood. Lots are generally modest to mid-sized, and the township's preserved-wetland boundaries limit large-scale development, keeping the housing stock established and its village character intact.

Long Hill Township comprises four distinct villages. Millington, at the southern end, grew around the Passaic River mills and has a compact village center near its rail station. Stirling, to the north, developed around its own station and a small commercial district. Gillette, along the Passaic River valley, retains a quieter, semi-rural character with older homes and open space. Meyersville, the smallest, sits in the township's rural western corner. The early Homestead Park subdivision, dating to the 1920s, is the township's first planned neighborhood. Together, the four villages give Long Hill a multi-centered structure unusual for a single municipality.

Long Hill's lifestyle is village-scaled and green. Residents live among four small village centers—each with its own rail station, shops, and civic life—set between the Great Swamp and the Passaic River. Weekend activity gravitates toward the refuge's trails and boardwalks for birding and walking, along with local parks and community events. The township's suburban streets are quiet and family-oriented, and its proximity to rail makes it popular with commuters who want open space without giving up a direct line to New York City. It is a low-key, outdoors-tinged version of Morris County living.

Public education in Long Hill Township is provided by the Long Hill Township School District, which serves students in kindergarten through eighth grade at elementary and middle schools within the township. For high school, students attend Watchung Hills Regional High School, which serves Long Hill along with several neighboring communities in the Watchung Hills region. This K–8 local district plus regional high school structure is common in Morris County and keeps younger students close to home while providing a larger high school with a broader range of programs.

Long Hill Township is well served by rail. Three NJ Transit stations—Millington, Stirling, and Gillette—sit on the Gladstone Branch of the Morris & Essex Lines, providing direct service to Summit, where riders can continue to Hoboken or New York Penn Station. This rail access is a defining feature of the township and a major draw for commuters. By road, the township is reached via county and state routes connecting to nearby Interstates 78 and 287, though the train remains the primary commute link for many residents heading toward New York City.

Recreation in Long Hill centers on the Great Swamp National Wildlife Refuge, a 7,455-acre preserve on the township's northern boundary with trails, boardwalks, and observation points for birding and wildlife viewing. The Passaic River along the southern and western edges offers additional greenway and riverside walking. Each village maintains local parks and playing fields, and the township's position in Morris County puts larger parks and trails within easy reach. The combination of a nationally significant wildlife refuge and a river corridor makes Long Hill unusually well-served by open space for a suburban New Jersey community.
