Twitter co-founder Jack Dorsey’s mansion build enters its 14th year

Key points

• Twitter co-founder Jack Dorsey has spent nearly 14 years renovating his San Francisco estate in the exclusive Sea Cliff neighbourhood. The property, valued at $US32 million, now includes a sauna complex, plunge pool and rooftop gardens.
• Neighbours say years of construction noise have disrupted the area's quiet. Dorsey first bought the property at 830 El Camino del Mar in 2012 and bought the adjoining home in 2018.
• At least 24 homes on the street have filed building permits since early 2025.
