Jupiter Key is a gated enclave on A1A in Jupiter, Palm Beach County, directly across the road from the Atlantic Ocean, with 67 residences, the majority Key West-style single-family homes plus a set of oceanside townhomes.
The single-family homes average around 2,400 square feet with picket fences, porches, and metal roofs, ranging from smaller two-bedroom plans near 1,777 square feet to larger newer three-story homes up to about 5,000 square feet with ocean views; most are three-bedroom homes near 2,100 square feet. The townhomes, built in 1995, run four floors with more than 3,000 square feet and two-car garages.
Amenities are simple and beachside: a security gate, a community pool and spa, and direct beach access moments away, with walkability to the ocean a defining feature. With only 67 residences, supply is scarce.
Diligence is the diligence of a 1990s-era coastal enclave: confirm the association and any townhome condo obligations including reserves and milestone status where applicable, the product type and position, the rules and any rental restrictions, the roof and systems on a coastal home, and insurance early. Price by product, position, and condition, not by the gate.
