Housing in Delaware Township is overwhelmingly single-family and low-density. Homes are scattered across the township rather than concentrated in large subdivisions, with many properties sitting on lots of an acre or more surrounded by trees, fields, and pasture. The stock spans eras and styles: restored farmhouses and stone homes near the historic villages, colonial and Victorian-era houses in Sergeantsville, and a mix of mid-century ranches and more recent custom homes set back from the roads. Some larger estate properties and equestrian-oriented parcels reflect the township's agricultural heritage. Because the township has prioritized farmland and open-space preservation, new construction is limited and the housing supply skews toward well-established, long-held homes. Most residents own their homes, and the market generally attracts buyers looking for privacy, land, and a rural lifestyle rather than walkable amenities or dense development.

Delaware Township is organized around its villages and hamlets rather than conventional subdivisions. Sergeantsville, the largest village, anchors the community with its historic crossroads, general-store heritage, and collection of early stone and frame houses. Rosemont, on the township's western side near the Delaware River, is another small historic settlement tied to the river and canal landscape. Between these villages, homes are dispersed along country roads, often at the end of long driveways with farmland and woods as neighbors. The Green Sergeant's Covered Bridge sits within this fabric, linking the Sergeantsville and Rosemont areas across Wickecheoke Creek. The overall pattern is one of open fields, preserved farms, and scattered residences, giving the township a cohesive rural identity rather than distinct named neighborhoods.

Life in Delaware Township is quiet and outdoors-oriented. Residents value the township's rural calm, preserved farmland, and access to the Delaware River, and much of community life revolves around the township's recreation programs, volunteer committees, and the Delaware Township School. Dilts Park serves as a local hub for youth sports and community events, while the D&R Canal State Park towpath offers walking and cycling along the river. Sergeantsville and the surrounding hamlets host seasonal gatherings, and the covered bridge and surrounding backroads are a draw for cyclists and weekend visitors exploring Hunterdon County's scenery. Everyday errands take residents to Flemington, Lambertville, or across the river into Pennsylvania, and the township's low population density means neighbors know one another and share a strong sense of place.

Delaware Township is served by the Delaware Township School District, which operates a single kindergarten-through-eighth-grade school on a 26-acre campus near Sergeantsville, about three miles from the Delaware River. The school enrolls roughly 390 students and is known for its small class sizes, with a student-teacher ratio near nine to one. For high school, students attend Hunterdon Central Regional High School, part of the Hunterdon Central Regional School District, which also serves East Amwell, Flemington, Raritan Township, and Readington. Hunterdon Central is one of the larger and more established high schools in the region, offering a broad range of academic, athletic, and extracurricular programs. The small elementary district feeding into a larger regional high school is a familiar pattern in rural Hunterdon County and is a key consideration for families moving to the township.

Delaware Township is reached primarily by two-lane county and state roads that wind through the Hunterdon countryside. County Route 579 runs north-south through the township, connecting Sergeantsville to Route 12 and Flemington, while Route 29 follows the Delaware River on the western edge, linking to Lambertville and the Route 202 corridor. For longer trips, residents connect to Interstate 78 to the north via nearby routes, putting the New York metro area and central New Jersey within commuting range, and to the Route 1 and Interstate 95 corridors toward Princeton and Philadelphia to the south. There is no rail service within the township; most commuters drive to stations in the region or rely on cars for daily travel. The Delaware River bridges and the nearby canal towpath add both scenic and practical connections across the river into Pennsylvania.

Outdoor recreation in Delaware Township centers on the Delaware River corridor and the surrounding farmland. The Delaware and Raritan Canal State Park, a linear park stretching more than 70 miles, runs along the river and provides a towpath for walking, running, and cycling, while the river itself supports canoeing, kayaking, fishing, and boating. Dilts Park offers the township's primary organized recreation facilities, including fields for youth sports and space for community events. Green Sergeant's Covered Bridge and the network of quiet country roads make the township a favorite for cyclists and photographers, particularly in the fall. Nearby, Hunterdon County's broader park system, the Sourland Mountain preserves, and the river towns of Lambertville and New Hope offer additional trails, dining, and cultural destinations within a short drive.
