Belvedere Island is a speck in the San Francisco Bay Area but holds, quite literally, some of the “richest” heritage when it comes to the region’s extreme wealth.

In the 1890s, wealthy San Franciscans quickly fell in love with the exclusivity of living on a parcel of land that’s just over a half mile in size with a Mediterranean-style climate and striking views of Richardson Bay and (eventually) the Golden Gate Bridge.

Houseboats on Belvedere Lagoon became another popular choice for affluent families looking for a summer vacation home, and more residences shifted from “second” to “primary” following a devastating 1906 earthquake that leveled much of San Francisco. 

Belvedere’s reputation endured through the 20th century and today it has one of the highest concentrations of wealth in the U.S. with a median household income of over $200,000 and an average home price nearing $3 million, according to U.S. News & World Report. While physically attached to the neighboring city of Tiburon, Belvedere is its own municipality with a city government overseeing a locale of fewer than 2,400 residents. 

Robin Williams, Tony Bennett and, more recently, former Apple designer Jony Ive are just a few of the notable names who have lived or currently reside on Belvedere. Although the area’s market has ebbed and flowed with the global economy, homes are typically in-demand with finite supply and a unique interest of living among regional and global titans. 

Prices

Realtor.com data shows general sales consistency from the most recent available numbers running November 2024 through November 2025. The median sales price of that span was $6.92 million with only a handful of sales given the extremely limited availability. That is likely only part of the picture, however, as a portion of Belvedere sales are typically off-market.

Golden Gate Sotheby’s agent Kara Warrin expects to break Belvedere’s per-square-foot price record with a soon-closing sale of a three-bedroom, 3.5-bath residence in an enclave known as “Billionaires Point” due to the wealth of those who live nearby. She expects the 2,935-square-foot home with unobstructed views of the Golden Gate Bridge to sell for $5,200 a foot, which would set a closing price of $15.262 million. The property was built in 1967, underwent a full renovation in 2005, then another comprehensive update in 2015. 

“I don’t think there’s a ceiling on prices, as our pricing is driven by emotion,” Wallin said. 

Compass Marin County luxury property specialist Bill Smith hopes to set an overall sales record on Belvedere with a three-level, midcentury mansion listed for $50 million. The property, which hasn’t been on the market in 48 years, underwent a significant renovation 10 years ago and Smith hopes that the turnkey estate will entice a buyer who is tired of the busyness and crowds of Atherton and Hillsborough to the south.

“I’m trying to find that person who wants ultimate privacy and a big home,” he said.

Perhaps the most notable recent string of purchases was from Ive, the former Apple designer, who spent nearly $73 million on four Belvedere homes in September. Three of the homes are in a row, set to develop into a family compound while the fourth is nearby. Local agents said the AI boom is fueling purchasing power. (Ive, for instance, sold his startup to OpenAI earlier in 2025 for a reported $6.5 billion). 

“In the next couple of years, I think we’re going to have a great run,” said the Agency agent Tracy McLaughlin. “We are working with a lot of people that have pending IPOs.”

Broad estimates suggest hundreds of billions of dollars of liquidity could pour into the Bay Area market by the end of 2026, and Smith suggested that will contribute to “strength coming down the line” in terms of buying potential.

Housing Stock

For a slice of land with a finite amount of homes, there’s a healthy mix of residential options. 

“We have a lot of historic homes,” Warrin said.  “It’s not all people tearing things down, but there are spec homes happening as well. It’s a real mishmash.”

An example of one of those historic options is the under-contract, eight-bed, nine-bath estate on Golden Gate Avenue. The 1907-built home unfolds across 7,700 square feet with period architectural details—including five wood-burning fireplaces and coffered ceilings—a wine cellar and yoga/fitness studio. It is expected to close near its listing price of $8.995 million. 

New construction is commanding a premium, such as the four-bed, five-bath modern residence on West Shore Road that closed earlier this year at $14.9 million. The angular property has views at almost every turn with blended indoor/outdoor living and a state-of-the-art boat dock.

When only five to 10 homes are available at any given time, the market tends to feel every movement or shift. When a developer purchases an older property to tear it down, there’s often a significant increase in that property’s value not only because of the newness, but because of the general scarcity and ongoing demand to live on Belvedere. 

“There’s an extreme mismatch between supply and demand,” Warrin said. 

Things to Do

People who live on Belvedere Island do so for its privacy, exclusivity and discretion. The town has no real retail and generally limited services, relying on neighboring Tiburon for additional support. 

That being said, the area is only 30 minutes by ferry or car to San Francisco, making it ideal for executives commuting into the city. That proximity also opens up much of what the Bay Area has to offer, whether that be yachting, cycling, hiking or points north to Napa and Sonoma wine country.
