In the geography of high-stakes real estate, the Tiburon Peninsula (ZIP 94920) is a trophy asset. While they are technically two separate municipalities—the Town of Tiburon and the City of Belvedere—they function as a singular, ultra-prime ecosystem. In 2026, this peninsula remains the premier choice for the principal who demands a “360-degree view” of the global economy: the San Francisco skyline, the Golden Gate Bridge, and the serene slopes of Mount Tamalpais.
At David Mayfair, we define this region as the “Visual Alpha” play. It is a market where price is determined not by square footage, but by “sightlines”—the precise angle at which the bay enters your living room.
The Belvedere Island Legacy: The Sovereign Peak
Belvedere is often cited as the wealthiest city in California per capita. It has no stores, no restaurants, and no through traffic. In 2026, it remains an intentionally residential fortress.
-
Belvedere Island: This is the pinnacle of the market. Estates here are carved into the hillsides, offering panoramic vistas. In March 2026, the median home price on the Island has cleared $11.3M, with trophy “west-side” properties reaching $25M to $60M.
-
The Lagoon: For those seeking a more tranquil, “paddle-board” lifestyle, the Belvedere Lagoon offers level lots and direct water access. It is the preferred choice for families who want a yard and a dock rather than a cliffside.
-
Corinthian Island: Positioned at the very tip of the peninsula, this tiny enclave offers the unique “Belvedere” tax and municipal status while being walkable to Tiburon’s Main Street.
Tiburon: The Vibrant Waterfront Center
While Belvedere is quiet, Tiburon is the “Social Anchor.” Its Mediterranean-style downtown is a collection of high-end galleries, yacht clubs, and waterfront dining that feels more like the Amalfi Coast than Northern California.
-
The “Shark’s Point” Market: In early 2026, the Tiburon housing market has shown incredible resilience, with prices up 35.4% year-over-year. The median sale price for a single-family home currently sits at $4.8M.
-
Ferry Connectivity: The Tiburon Ferry remains the most dramatic commute in the world. In 18 minutes, residents can travel from their “vacation” life to the Financial District of San Francisco, a logistical advantage that continues to drive the peninsula’s high liquidity.
-
The “Old Tiburon” Factor: The winding roads of Old Tiburon offer a diverse mix of mid-century modern gems and newer custom builds. Inventory remains critically low, with homes moving in a median of 21 days.
The Reed Union School District: The “Institutional Floor”
Like our other “Institutional Fortresses,” the peninsula’s value is anchored by its schools. The Reed Union School District (Reed, Bel Aire, and Del Mar) is a perennial top-tier performer.
-
Excellence by the Numbers: In 2026, student proficiency in math and reading remains in the top 1% of the state. With a student-teacher ratio of just 15:1, the district provides a private-school experience that keeps families rooted on the peninsula for decades.

Strategic Summary
Tiburon and Belvedere are for the individual who values Perspective and Proximity. It is a market that rewards those who understand the nuances of the peninsula—where a home three houses down can be worth double due to its view of the Bridge. In the David Mayfair portfolio, a 94920 address is the “Blue Chip Vista”—an asset that offers a quality of life so visually and logistically superior that its value is effectively permanent.
