Seaside Heights' housing reflects its identity as a dense shore resort. The borough holds a mix of older beach bungalows, duplexes, and multi-family properties, along with condominiums and newer single-family homes, much of it built on compact lots between the ocean and Barnegat Bay. A substantial share of the housing stock serves seasonal and summer-rental use, with many owners using their properties part of the year and renting them to vacationers in season. This gives the borough a distinct market character: a high proportion of income-producing and second-home properties, set within a walkable grid just steps from the boardwalk and beach.

Seaside Heights is defined by the classic Jersey Shore summer. The boardwalk — anchored by Casino Pier and Funtown Pier — fills with the sounds of amusement rides, arcade games, and beachgoers, while Breakwater Beach waterpark and the wide Atlantic beach draw families all season. The borough gained national recognition as a filming location for MTV's "Jersey Shore," cementing its place in pop culture. Winter is far quieter, with a small year-round community and many seasonal businesses closed. Day-to-day life revolves around the beach, the boardwalk, and the bay, with Toms River and the rest of Ocean County just a short drive away for year-round shopping, services, and schools.

Seaside Heights operates its own pre-kindergarten through elementary school through the Seaside Heights School District, giving the borough's youngest students a small, local school. For grades 7 through 12, students attend Central Regional schools under a sending/receiving arrangement, traveling to the regional district's middle and high school campuses outside the borough. The borough has explored regionalization of its school system given its small size, but as a sending district it relies on Central Regional for secondary education. Families also have access to private and parochial schools in neighboring shore communities and Toms River.

Seaside Heights sits at the junction of two Ocean County highways: New Jersey Route 35 runs through the borough along the peninsula, and Route 37 terminates at Route 35 in Seaside Heights after crossing Barnegat Bay from Toms River. This makes the borough a natural endpoint for traffic coming from the mainland and the Garden State Parkway, which is a short drive west. Toms River, the county's largest community, is a few minutes away across the bay, providing access to shopping, healthcare, and services. Within the borough, the compact street grid is walkable, and the beach, boardwalk, and bay are all within easy reach on foot or by bicycle.

Recreation in Seaside Heights centers on its beach and boardwalk. The Atlantic shoreline provides swimming, surfing, and sunbathing, while Casino Pier offers amusement rides and classic boardwalk games and the adjacent Breakwater Beach waterpark adds slides and water attractions. Funtown Pier anchors the boardwalk's southern end. Fishing is available from the pier and the surf, and Barnegat Bay on the west side supports boating, crabbing, and kayaking. Immediately south, Island Beach State Park preserves miles of undeveloped barrier-island beach for swimming, fishing, and birding, making the borough a gateway to one of New Jersey's most significant coastal natural areas.
