Jupiter Island and the Areas Around It
The Town of Jupiter Island is a barrier-island town of roughly 705 taxable parcels along nine miles of Atlantic frontage, in Martin County rather than Palm Beach County. It is the most expensive and least liquid market we cover. Here is how the surrounding areas compare. Click into any area to browse its listings.
Town of Jupiter Island
705 taxable parcels on about 1,643 acres, roughly 820 permanent residents rising to about 2,000 in season. Martin County, Hobe Sound 33455 mailing address.
Tequesta
The nearest village to the south, across the county line, with its own police, fire and water and a far more accessible price point. Its Beach Road strip sits on the same barrier island.
Jupiter
The main market south of the county line, with real inventory, a working town centre, hospitals and schools, and coastal property at a fraction of Jupiter Island pricing.
Jupiter Hills
Also unincorporated Martin County, a few minutes inland, with two Fazio courses on dune terrain and a wide range of product from the high $400s upward.
Four Reasons Buyers Choose Jupiter Island
Nine miles of ocean, 705 parcels
That ratio is the whole proposition. The town runs along nine miles of Atlantic frontage on roughly 1,643 acres, bounded on the west by the Intracoastal, and holds just 705 taxable parcels. The town describes itself in its own planning language as a low-density residential community that seeks to preserve natural resources to the maximum extent possible, and the parcel count shows it means it.
A town that has been defending its own beach since the 1950s
Jupiter Island created a dedicated Beach Protection District in 1982, funded by its own ad valorem erosion tax, and describes its nourishment programme as one of the longest running in the United States. Whether you read that as reassurance or as a warning depends on your outlook, but it is a level of institutional commitment to shoreline maintenance that almost no comparable town has, and it is funded rather than aspirational.
Conservation land that will never be built on
Much of what surrounds the town is permanently protected, and it was given away deliberately. Blowing Rocks Preserve, 73 acres held by The Nature Conservancy, contains the largest Anastasia limestone shoreline on the Atlantic coast, where spray can shoot fifty feet in the air, and it is a nesting beach for loggerhead, green and leatherback turtles. Five hundred acres at the north end went to the federal government in 1976. That scenery is not a planning assumption; it is deeded.
Privacy enforced by ordinance, not just custom
The town regulates construction hours by law, with different summer and winter windows, restricted Saturdays and holiday blackouts, alongside a Development Review Board and layered zoning, drainage, engineering, design review, fire and floodplain approvals. If you are building, that is friction. If you already live there, it is precisely what you are paying for: your neighbour's renovation cannot run at seven in the morning on a holiday weekend.
Jupiter Island: Taxes, Jurisdiction and the Name Problem
First, the Town of Jupiter Island, which is what this page is about: a Martin County barrier-island town of 705 parcels where individually reported sales run from roughly $18 million to $39 million. Second, ZIP code 33455, which carries a Hobe Sound mailing address and is mostly mainland; portal medians for that ZIP sit around $525,000 to $592,000, because they are measuring the mainland, not the town. Third, a neighbourhood in Stuart that some property portals also index as Jupiter Island. Separately, Jupiter Inlet Colony is a different town again, on the southern tip of the same barrier island but in Palm Beach County. If you see a Jupiter Island median that looks affordable, it is almost certainly measuring one of the other three. We have not published a median on this page for exactly that reason.
| County and jurisdiction | Martin County, not Palm Beach County. The property appraiser, tax collector, permitting authority and school district are all Martin County. Town Hall is at 2 Bridge Road, Hobe Sound, Florida 33455. |
| Population | 804 at the 2020 Census. The town reports roughly 820 permanent residents rising to about 2,000 in season. American Community Survey estimates put households at about 358, median household income around $219,700, median age 64.4, and homeownership at about 95.8 percent. |
| Incorporated / history | Incorporated in 1953. The island's modern history runs through the Reed family, who bought in during the 1930s and held major landholdings until 1996, founded the residents committee and the Island Club in 1944, donated land for the police and fire station and for what became Hobe Sound public beach in 1945, gave south-end land to The Nature Conservancy in 1968, and 500 north-end acres to the federal government in 1976. |
| Size / housing stock | 705 taxable parcels across about 1,643 acres, with nine miles of ocean frontage and the Intracoastal Waterway as the western boundary. Town-wide final taxable value for 2025 was $3,988,199,993, which averages roughly $5.7 million of taxable value per parcel. That is an average of assessed value, not a median sale price. |
| Millage: town levies | Three separate town-level levies for tax year 2025: Town of Jupiter Island operating 2.8259 mills, Jupiter Island Beach Protection District 0.9593 mills, and an Electric Undergrounding voted-debt levy of 0.2100 mills, for a town subtotal of 3.9952 mills. |
| Millage: everything else | Martin County Board of County Commissioners 6.5614 mills, Martin County School District 5.1770, Children's Services Council 0.3618, and South Florida Water Management District levies totalling about 0.2301. Combined with the town levies that comes to roughly 16.33 mills, or about $163,000 a year on $10 million of taxable value. |
| The beach protection tax | Worth understanding before you buy. The Beach Protection District was created in 1982 and is funded by a dedicated erosion tax on all town property. It is currently levied at 0.9593 mills but is authorised up to 10 mills. That is a very large amount of headroom, and it exists because the town has committed to defending its shoreline indefinitely. |
| Jupiter Island Club | Private and members-only. The club publishes no fee information and its website blocks access. We could find no source establishing whether membership is required of residents, so we are not going to claim it either way. Several third-party sites sell "estimated" initiation fees and dues; those are marketing estimates rather than disclosures and we have not repeated them. The club's founding date is itself disputed, with the town's own history citing 1944 and an industry directory citing 1931. |
| Building and renovation | Expect friction. Permit fees for new single-family construction are calculated on square footage, and there are separate zoning, drainage, engineering, design review, fire and floodplain fees, plus a Development Review Board. Construction hours are legally restricted, with different summer and winter windows, Saturday limits and holiday blackouts. Lot sizes, height limits and setbacks were not obtainable from the town's code, so confirm those for any specific parcel. |
| Schools | Martin County School District, which was rated an A district for 2025 to 2026, its second consecutive year. Hobe Sound Elementary was graded B and South Fork High A in the most recent release. We could not confirm which schools Jupiter Island addresses are actually zoned to, so verify the assignment for a specific property with the district rather than assuming the usual feeder pattern. |

Jupiter Island Market Context, 2026
We are not going to publish a median sale price for Jupiter Island, and the reason is worth stating plainly: there is no authoritative public dataset for a town of 705 parcels, and the sources that claim one disagree with each other by more than twentyfold because most of them are measuring somewhere else entirely.
What can be verified are individual transactions reported by named publishers. TCPalm reported a sale at about $18.85 million in June 2026, a $39 million sale at 320 South Beach Road in January 2025 that was the highest on the Treasure Coast that year, a $33 million top sale in 2024, and sales at $29 million and $23.5 million. The one properly attributable market ranking is TCPalm, December 3, 2024, reporting that beach houses on Jupiter Island sold for an average of $8.7 million that autumn, making it the fourth most expensive oceanfront market in Florida. Note that is in Florida; a syndicated restatement upgraded it to "in the U.S." and that is not what the original said. Historically, Worth magazine ranked the town first nationally for highest median home sale price in June 1999, which is genuine but is now twenty-seven years old. Median closed price, sales count and days on market are all unavailable from any source we could verify. Sources accessed July 2026. Ask Dylan for the actual Martin County closed comparables.
When Jupiter Island May Not Be the Right Fit
This is the narrowest market in the region, and the reasons to look elsewhere are structural rather than a matter of taste.
705 parcels, no credible published median, no reliable sales count and no verifiable days-on-market figure. Individually reported sales run from roughly $18 million to $39 million and one aggregator suggested days on market above 200. Valuation here is a matter of comparables assembled by hand, and an exit can take a long time. If you may need to sell on a timetable, this is the wrong market.
The town has levied a dedicated erosion tax since 1982 and has been nourishing its beach since the 1950s. That is admirable stewardship and it is also the town telling you, in its own budget, that this shoreline needs permanent defence. The district is authorised to levy up to 10 mills against the 0.9593 currently charged, so the cost ceiling is high and the exposure is real. Factor windstorm and flood insurance in early.
It is Martin County, with a Hobe Sound mailing address, which changes your appraiser, tax bill, permitting authority and school district. Total millage runs about 16.33, and a second-home buyer gets no homestead exemption or Save Our Homes protection against it. If a Palm Beach County address matters, look at Tequesta or Jupiter.
There is minimal commercial activity in the town by design, so shops, restaurants and services mean driving to the mainland. And renovation is deliberately slow: square-footage-based permit fees, multiple layered approvals, a Development Review Board, and construction hours restricted by law including holiday blackouts. For a coastal property you can actually work on at pace, Juno Beach or Singer Island are more practical.
Jupiter Island vs. the Areas Buyers Shortlist Against It
vs. Tequesta
The two share a barrier island but almost nothing else. Tequesta is a Palm Beach County village of 6,299 people with its own police, fire and water, a two-storey mainland height cap, and a whole-market median around $652,000. Jupiter Island is a Martin County town of 705 parcels where reported sales start around $18 million. Tequesta's own Beach Road strip is the affordable way to be on this island.
Tequesta for barrier-island access at a normal price with municipal services; Jupiter Island for scale of estate, privacy and nine miles of protected oceanfront.
vs. Jupiter
A practical comparison rather than a like-for-like one. Jupiter offers real inventory, a functioning town centre, hospitals, schools and coastal property at a small fraction of the price, all inside Palm Beach County. Jupiter Island offers something Jupiter structurally cannot: a nine-mile stretch of ocean with only 705 parcels on it, permanently bracketed by conservation land.
Jupiter for liquidity, services and value; Jupiter Island only if privacy and oceanfront scale are the entire point and price is not a constraint.
Buying on Jupiter Island: What to Know
Which county is Jupiter Island in, and why does it matter?
Martin County, with a Hobe Sound 33455 mailing address, despite the Jupiter name. It matters because your property appraiser, tax collector, permitting authority and school district are all Martin County, and none of the Palm Beach County comparisons carry across. Note also that Jupiter Inlet Colony, on the southern tip of the same barrier island, is a separate town in Palm Beach County with its own ZIP, and the Town of Jupiter is a different place again on the mainland.
What is the property tax rate?
For tax year 2025 the town levies three separate rates: 2.8259 mills operating, 0.9593 mills for the Beach Protection District, and 0.2100 mills of voted debt for electric undergrounding, totalling 3.9952 mills at town level. Adding Martin County at 6.5614, the school district at 5.1770, the Children's Services Council at 0.3618 and water management district levies of about 0.2301 gives roughly 16.33 mills in total, or about $163,000 a year on $10 million of taxable value. A second-home buyer receives no homestead exemption or Save Our Homes protection against that.
Why do online price estimates for Jupiter Island vary so wildly?
Because at least three different places share the name. The Town of Jupiter Island is a barrier-island town of 705 parcels where reported sales run from roughly $18 million to $39 million. ZIP code 33455 is mostly mainland Hobe Sound, and portal medians for that ZIP land around $525,000 to $592,000. There is also a neighbourhood in Stuart indexed as Jupiter Island by at least one portal. Any figure in the hundreds of thousands is measuring the mainland, not the town, and the gap between them is more than twentyfold.
Is membership in the Jupiter Island Club required, and what does it cost?
We do not know, on either count, and we would rather say so. The club is private and members-only, publishes no fee information, and its website blocks access. We found no source establishing whether membership is required of residents, so we are not going to assert it in either direction. Several third-party directories sell estimated initiation fees and dues for this club; those are marketing estimates rather than disclosures and we have not repeated them. Even the club's founding date is disputed, with the town's own published history citing 1944 and an industry directory citing 1931.
What is the beach protection tax?
A dedicated ad valorem levy on all town property, funding a beach nourishment programme the town describes as one of the longest running in the United States, dating to the 1950s. The Beach Protection District was formally created in 1982. It is currently levied at 0.9593 mills, but it is authorised to levy up to 10 mills. That headroom is the single most important thing a buyer should understand about long-term carrying cost here, because it means the town has the standing authority to raise coastal defence spending substantially without a new referendum.
What is nearby, and what are the schools?
Blowing Rocks Preserve, 73 acres owned by The Nature Conservancy, sits on the island and contains the largest Anastasia limestone shoreline on the Atlantic coast, where wave spray can reach fifty feet; it is a nesting beach for loggerhead, green and leatherback turtles and is open daily. Five hundred acres at the north end were given to the federal government in 1976. Commercial amenities in town are minimal by design, so shopping and dining mean the mainland. Schools are Martin County School District, rated an A district for 2025 to 2026; confirm the specific assignment for an address with the district rather than assuming a feeder pattern.
