Dorsey’s two adjoining properties are located in Sea Cliff, an exclusive neighbourhood overlooking the Pacific Ocean and the Golden Gate Bridge. The properties cover a combined area of 1.21 acres along El Camino del Mar.
Despite the expensive homes and scenic surroundings, the neighbourhood has reportedly been filled with the sounds of jackhammers, cement mixers and construction trucks for more than a decade, according to SFGate.
The plans included seismic upgrades, additional living space, roof decks and a planted roof. However, it took three and a half years to obtain the permit. Dorsey is not the only technology billionaire to acquire neighbouring properties to create a large residential compound. Meta founder Mark Zuckerberg has purchased adjoining estates in Lake Tahoe, while OpenAI CEO Sam Altman has also assembled multiple neighbouring properties around his San Francisco mansion. During a recent visit, the outlet observed mansions covered in scaffolding, construction workers occupying sidewalks and heavy equipment operating outside expensive homes.
In December 2013, a major redevelopment application proposed improvements worth $3.7 million. A further redesign was submitted in 2020, proposing changes to the property’s windows, courtyard and exterior finishes. The plans received approval in July 2022. At least 24 homes along the eight-block stretch of El Camino del Mar have filed building permits since the beginning of 2025, according to planning documents.
