What county is the Town of Jupiter Island in?

Martin County — not Palm Beach County, despite the name 'Jupiter' shared with the adjacent mainland town of Jupiter in Palm Beach County. The Town of Jupiter Island is a 7.5-mile barrier-island municipality with a population of roughly 800 year-round residents, administered independently from both the Town of Jupiter on the mainland and the unincorporated Hobe Sound area to the west.

How does Jupiter Island's design review work?

The town operates a rigorous building and design review through its Building Department and town commission. Expectations on massing, setback, exterior materials, roof pitch, and compatibility with the established streetscape are enforced closer to the Town of Palm Beach standard than to typical Martin County municipalities. Oceanfront parcels additionally trigger Florida's Coastal Construction Control Line process via FDEP — which should run in parallel with the town's review to avoid adding 4 to 6 months of sequential delay.

What are typical Jupiter Island transaction values?

Prime oceanfront transactions on Jupiter Island regularly exceed $30 million. The highest tier — the largest ocean-to-Intracoastal parcels with private beach frontage — clears $80 million to $100 million-plus. Intracoastal-facing parcels without direct ocean access run meaningfully lower, typically $8 million to $25 million. The thin inventory and strict town review mean transactions are sparse: prime parcels often trade off-market and rarely come to public listing.

What construction costs apply to Jupiter Island new-build?

Oceanfront new construction on Jupiter Island runs $1,200 to $2,200 per square foot, excluding land, architecture, landscape, FF&E, pool, and dock. The premium above Palm Beach County oceanfront reflects longer logistics (the island is served by a single bridge), a tighter local subcontractor pool, the town's materials and detailing expectations, and the scale of typical programs — 10,000 to 20,000 square feet with extensive outdoor living, guest quarters, and staff housing is not unusual.

Does Sabal have delivered experience relevant to Jupiter Island?

Sabal's Palm Beach County delivered work — 4005 S Ocean Blvd in Highland Beach (CCCL oceanfront), 3050 S Ocean Blvd in Manalapan (ocean-to-Intracoastal), 751 Tern Point Circle in Boca Raton's Sanctuary (community ARC) — translates directly to Jupiter Island's review environment. The CCCL pathway, oceanfront foundation engineering, the Town of Palm Beach-grade design review rigor, and the barrier-island logistics challenges are the same competencies Jupiter Island mandates require.

Overview

Jupiter Island, Jupiter Island

The Town of Jupiter Island is a 7.5-mile barrier-island town in Martin County, separated from the Florida mainland by the Intracoastal Waterway. Geographically narrow and almost entirely single-family residential, it is one of the most privately-held stretches of oceanfront real estate in the United States — home to long-tenured families and, at various points, a small number of very private high-profile residents. The town's design-review process is among the strictest in Florida: a combination of the Town's own review and, on most oceanfront work, the Florida Coastal Construction Control Line regime administered by FDEP. Prime oceanfront transactions on Jupiter Island regularly exceed $30M, with the highest tier clearing $80M to $100M-plus on the largest ocean-to-Intracoastal parcels.

Why Sabal in Jupiter Island

Building on Jupiter Island means working inside a review environment closer to the Town of Palm Beach than anywhere else in the state — strict massing, setback, materials, and streetscape expectations, administered by a town government whose constituents have chosen the address specifically for its protection from commercial and architectural drift. Sabal's Palm Beach County working history — ARCOM, Gulf Stream ARPB, the Manalapan Architectural Commission — translates directly to the Jupiter Island process. The CCCL pathway on oceanfront parcels is identical to the one the firm has exercised at 4005 S Ocean Blvd (Highland Beach) and 3050 S Ocean Blvd (Manalapan).
