Seaside Heights Neighborhoods: Boardwalk Blocks and Bayside Blocks
Seaside Heights is a genuinely tiny borough -- 0.74 square miles total, just 0.62 square miles of land and 0.13 square miles of water -- sitting on the Barnegat Peninsula between Barnegat Bay and the Atlantic Ocean. This page is not going to invent a list of named neighborhoods to make a town this size look bigger than it is. No confirmed, documented set of named neighborhoods, subdivisions, or wards inside Seaside Heights turned up in this research pass, so none appear here. What is real, and confirmable, is a much simpler geographic split: blocks close to the 2-mile oceanfront boardwalk and Casino Pier, versus blocks on the Barnegat Bay side of the peninsula. That distance-from-the-boardwalk variable, not a named-neighborhood system, is what actually organizes this town.
Why This Guide Talks About Blocks, Not Named Neighborhoods
Seaside Heights is this site's nineteenth New Jersey market, and the first built north of the now fully-built Long Beach Island cluster of Ship Bottom, Surf City, Harvey Cedars, and Barnegat Light -- a different barrier peninsula reached via NJ Route 37 and the Toms River, not Route 72. It shares none of those towns' identity: it is the site's first genuinely nightlife-and-amusement-anchored New Jersey market, built around Casino Pier, the 2-mile boardwalk, and its real history as the filming location for MTV's Jersey Shore. It is also, at 0.74 square miles, simply too small to have generated a documented set of named residential neighborhoods the way a sprawling suburban town would.
That is not a research gap to apologize for -- it is a fact about the borough's scale. A town incorporated on February 26, 1913 out of portions of Berkeley Township and Dover Township, with a 2020 census population of just 2,440 living across roughly six-tenths of a square mile of land, does not need, and does not have, a neighborhood map. What buyers and renters actually navigate here is proximity: how many blocks a property sits from the boardwalk and Casino Pier, and whether it sits on the ocean side of the peninsula or the bay side.
Oceanfront and Boardwalk Blocks: The Two-Mile Strip Anchored by Casino Pier
The oceanfront blocks running along Seaside Heights' 2-mile boardwalk are the borough's most recognizable stretch. Casino Pier, extending roughly 300 feet into the Atlantic, traces back to 1915, when the Senate Amusement Company of Philadelphia built a covered pier housing a carousel under Joseph Vanderslice's direction before selling it to Frank Freeman in 1916. The completion of the Toms River Bridge on October 23, 1914, combined with the new pier and boardwalk, helped drive a 159% population surge in the borough between the 1920 and 1930 censuses -- an early sign of how much the boardwalk itself has always shaped which blocks of this town filled in first.
This stretch is also where Seaside Heights' most dramatic, widely photographed piece of history happened: during Hurricane Sandy, beginning October 29, 2012, Casino Pier's Star Jet roller coaster fell into the Atlantic Ocean and, partially submerged, became an internationally recognized image of the storm's destruction before it was demolished on May 14, 2013. A replacement coaster reportedly opened at Casino Pier in 2017, and more recent reporting references a further, newer "Hydrus" coaster; no single, current 2026 ride lineup for Casino Pier was confirmed in this research pass, so none is presented here as settled fact. What is confirmed is that blocks nearest this stretch sit closest to the borough's amusement anchor, its boardwalk foot traffic, and the dramatic seasonal swings that come with both.
Bayside Blocks: The Quieter Side of the Peninsula
Seaside Heights sits on the Barnegat Peninsula, a barrier peninsula separating Barnegat Bay to the west from the Atlantic Ocean to the east. That geography means every block in the borough falls somewhere between those two shorelines, and the bay side is the borough's other real organizing axis alongside the boardwalk. This research did not confirm specific street-level naming for bayside blocks, nor any documented price differential between bayside and oceanfront property here, so neither is stated as fact.
What can be said honestly is structural: in a borough only 0.62 square miles of land, bayside blocks are, by definition, a short walk or drive from the boardwalk rather than a separate part of town in the way "bayside" might imply in a larger municipality. Anyone comparing a bay-side listing to a boardwalk-adjacent one here is really comparing degrees of proximity to Casino Pier and the ocean, not two distinct neighborhoods with their own separate identities.
Proximity to the Boardwalk Is the Real Variable, Not a Neighborhood Name
Seaside Heights' 2020 census population was 2,440, down 447 people, or 15.5%, from 2,887 in 2010, and down further still from 3,155 in the 2000 census. That year-round base is genuinely small. What swells dramatically is the summer population: reported estimates put it anywhere from roughly 30,000 to 65,000, driven largely by young adults under 21 drawn to boardwalk nightlife -- a wide, reported range rather than a precise figure, and it should be read that way.
That swing is a real, lived-experience variable a buyer or renter should weigh block by block, and it is a bigger factor here than any neighborhood label would be. A block a few hundred feet from Casino Pier and the boardwalk experiences a genuinely different summer than a block on the bay side of the same tiny borough -- more foot traffic, more nightlife noise, and more of the reality-TV-era reputation that came from MTV's Jersey Shore filming its first, third, and fifth seasons in the borough between 2009 and 2011. Neither is objectively "better" -- they are simply different trade-offs inside a town too small to separate them by more than a few blocks.
Seaside Heights vs. Seaside Park: Two Very Different Neighbors
Seaside Heights borders Seaside Park immediately to the south, and the two towns are frequently confused by outsiders because they share a name, share a stretch of boardwalk, and sit on the same barrier peninsula. They are not the same market. Seaside Heights is the nightlife-and-amusement town -- Casino Pier, the Jersey Shore filming history, and a summer population that swells many times over its year-round base. Seaside Park's own identity, covered separately, leans quieter and more residential.
One point worth flagging honestly rather than blurring: a ten-alarm fire swept the shared boardwalk's Funtown Pier on September 12, 2013, destroying businesses including Jack & Bill's Bar and Kohr's Custard -- both of which had also burned in Seaside Heights' 1955 "Freeman's Fire." The detailed damage figures for that 2013 fire, however, are documented under Seaside Park's own municipal history, since the fire's most detailed accounting concerns the Seaside Park end of the boardwalk. This page states only the general fact and does not invent a Seaside-Heights-specific damage count for it.
What This Page Does Not Have
No list of named neighborhoods, no subdivision map, and no bayside-versus-oceanfront price comparison appears here, because none was confirmed during this research pass, and inventing one for a 0.74-square-mile borough would do a buyer more harm than an honestly disclosed gap. What this page can responsibly offer is the real structure underneath: a narrow barrier-peninsula town with a 2-mile oceanfront boardwalk and Casino Pier on one side, Barnegat Bay on the other, a tiny year-round population, and a summer crowd that can outnumber it many times over.
For block-by-block detail -- which specific streets sit closest to Casino Pier, how a bayside listing actually compares to a boardwalk-block one, and current pricing for either -- talk to a local Ocean County real estate agent who works Seaside Heights specifically. That conversation can give you the granularity this research pass could not confirm at a citywide level.

Data drawn from research on Seaside Heights, New Jersey: a total area of 0.74 square miles (0.62 square miles land, 0.13 square miles water) on the Barnegat Peninsula, a barrier peninsula separating Barnegat Bay from the Atlantic Ocean, reached via NJ Route 37 and the Toms River; incorporation as a borough on February 26, 1913 following a March 25, 1913 referendum, from portions of Berkeley Township and Dover Township (now Toms River Township); a 2-mile oceanfront boardwalk with Casino Pier and the former Funtown Pier each extending roughly 300 feet into the Atlantic; Casino Pier's origin in 1915 under the Senate Amusement Company of Philadelphia and Joseph Vanderslice, sold to Frank Freeman in 1916; the October 23, 1914 completion of the Toms River Bridge and its role, alongside the pier and boardwalk, in a 159% population surge between the 1920 and 1930 censuses; the June 9, 1955 "Freeman's Fire," which destroyed 85 buildings including the DuPont Avenue carousel; Hurricane Sandy's October 29, 2012 impact, the Star Jet roller coaster's fall into the Atlantic and its demolition on May 14, 2013, and reported 2017 and later replacement coasters at Casino Pier including one referenced as "Hydrus," presented without asserting a single current 2026 ride lineup; the September 12, 2013 ten-alarm Funtown Pier fire that destroyed businesses including Jack & Bill's Bar and Kohr's Custard, both of which had also burned in 1955, with detailed damage figures attributed to neighboring Seaside Park's own municipal history rather than invented for Seaside Heights; Seaside Heights' role as the primary filming location for MTV's Jersey Shore (season one in August 2009, season three from July-September 2010, season five filming concluding August 2, 2011); a 2020 census population of 2,440, down 447 (15.5%) from 2,887 in 2010, itself down from 3,155 in 2000; and reported summer population estimates ranging from roughly 30,000 to 65,000, presented as a reported range rather than a precise figure. Seaside Heights borders Seaside Park to the south; this page does not restate Seaside Park's own detailed boardwalk-fire figures, and it does not restate any Long Beach Island market's own spine (Ship Bottom's shipwreck and Ron Jon history, Surf City's Connors mayoral dynasty, Harvey Cedars' Karan dune-easement case, or Barnegat Light's lighthouse and fishing fleet) as Seaside Heights' own. No confirmed list of named neighborhoods, subdivisions, or wards within Seaside Heights, no bayside-versus-oceanfront price differential, no current median home price or property tax rate, and no single confirmed current Casino Pier ride lineup were found in this research pass, and none is invented here. New Jersey has its own state sales tax (currently 6.625%) and its own property-tax structure, genuinely different from a no-sales-tax state, and none of that is assumed to carry over from any other market on this site.
