Belleville's housing stock is dominated by single-family Colonials, many dating to the early twentieth century, with semi-attached duplexes, attached townhouses, and rowhouses rounding out the inventory. Lot sizes are generally smaller than in other Essex County communities, reflecting the township's density and age. The market appeals to first-time buyers, growing families, and downsizers seeking more space than Manhattan or Jersey City offer, at a lower price point than many surrounding suburbs.

Belleville is a compact township organized around its commercial corridors and Passaic River frontage rather than large subdivisions. The Valley neighborhood and other residential areas feature classic single-family Colonials on tree-lined streets. Washington Avenue serves as the main commercial spine, lined with a diverse range of eateries and shops. Branch Brook Park, with its famous cherry blossoms, runs along the township's southern edge and serves as the community's signature green space.

Life in Belleville is dense, diverse, and community-oriented. Washington Avenue anchors the local dining scene with a wide range of ethnic eateries, and Branch Brook Park offers seasonal cherry blossoms, walking paths, and green space along the township's edge. Residents benefit from the township's proximity to Newark's cultural institutions, restaurants, and sports venues, while the short commute to Manhattan keeps New York's amenities within easy reach. The feel is urban-suburban, with walkable blocks and a strong sense of local identity.

Public education in Belleville is provided by the Belleville School District, a Pre-K–12 district serving the township with about 10 schools and roughly 5,000 students. The district's schools serve a diverse student body, and the township's compact geography keeps most schools within walking distance of residential areas. Nearby higher-education options, including institutions in Newark and across Essex County, add to the area's educational landscape.

Belleville sits about 13 miles from Manhattan and is well positioned for commuting into New York City. Although the township has no train station of its own, the Newark Light Rail's Branch Brook Park station lies just to the south, connecting to Newark Penn Station, where the PATH train reaches downtown Manhattan and NJ Transit trains serve Midtown. Major regional highways connect Belleville to the rest of northern New Jersey, and buses serve the township's local corridors.

Branch Brook Park, running along Belleville's southern edge, is the township's defining outdoor amenity, famous for its spring cherry blossom display and offering walking paths, recreation fields, and green space. The Passaic River provides a waterfront setting, and the township's parks and playgrounds serve neighborhood recreation. Residents also draw on the larger park systems of Essex County, including nearby reservations and Newark's recreational and cultural facilities.
