Twitter co-founder Jack Dorsey has spent nearly 14 years renovating his San Francisco mansion. The $32 million property in the exclusive Sea Cliff neighbourhood overlooks the Pacific Ocean and the Golden Gate Bridge. However, construction has continued since shortly after he bought the house in 2012. The project has included seismic upgrades, redesigned interiors, landscaped roofs, solar panels, pools, and extensive outdoor work, with permits filed over multiple years.Meanwhile, construction activity has affected the surrounding neighbourhood, with residents complaining about noise, trucks, and workers occupying the streets, an SF Gate report noted. Dorsey also purchased the neighbouring property in 2018, expanding his real estate holdings to approximately 1.21 acres. Despite the scale of the investment, the renovation still frustrates neighbours along one of San Francisco’s most expensive residential streets.How Jack Dorsey’s mansion renovation beganDorsey purchased the property at 830 El Camino del Mar through a limited liability company in February 2012 for $9.99 million. Built in 1965, the modernist house has two bedrooms and two bathrooms and covers approximately 3,734 square feet on a 0.59-acre plot.The first major redevelopment application was submitted in December 2013. Valued at $3.7 million, the proposed work included seismic strengthening, a new lower level, roof decks and a planted roof. The garage was also planned to be converted into living space.However, the city did not issue the permit until June 2017, more than three years after the application was filed. The city later cancelled another application for a new residence and garage, while a substantial redesign submitted in February 2020 was approved in July 2022.What the renovation includesArchitectural plans reviewed by SFGATE describe a coastal residence combining stone, glass and salvaged redwood. The design includes three planted roofs, an open central courtyard, motorised windows and skylights, and an ocean-facing balcony overlooking China Beach and the Golden Gate Bridge.The planned amenities extend beyond the main living areas. The property includes a plunge pool, hot tub, steam room and sauna complex, along with a gym, bicycle storage, outdoor seating and a fire pit. The roofs also feature 34 solar panels.Additional applications have covered retaining walls, driveway modifications, landscaping, fire sprinklers, batteries, an underground cistern and other infrastructure. Plumbing permits alone have continued from 2021 through 2026.Jack Dorsey bought the neighbouring mansionIn November 2018, Dorsey purchased the neighbouring property at 840 El Camino del Mar for $21.9 million. The five-bedroom house, built in 1962, sits on about 0.62 acres and reportedly sat vacant for around 15 years before the purchase.The combined properties cost approximately $31.9 million and cover around 1.21 acres. Although some landscaping and retaining walls cross the boundary between the two sites, the plans SFGATE reviewed do not show the houses being joined into a single structure.Dorsey’s purchases came amid a broader trend of wealthy technology executives acquiring neighbouring properties to create larger private compounds.Why Jack Dorsey’s San Francisco neighbours are frustratedSea Cliff was designed as a quiet residential neighbourhood, with winding streets, greenery and views of the coastline. However, extensive construction has disrupted that atmosphere, with trucks, cement mixers, machinery and building crews frequently occupying the streets.An SFGATE review of planning documents found that at least 24 homes along El Camino del Mar had filed building permits since the beginning of 2025. Dorsey’s project is therefore part of a wider wave of renovations affecting the neighbourhood.One neighbour expressed frustration during an SFGATE visit, saying, “This always happens.”The work is ongoing and has turned parts of the street into a construction zone, despite the neighbourhood’s well-known reputation for secluded coastal living.Dorsey’s renovation reflects the complexity of redeveloping a high-value coastal property, where structural work, landscaping and individual design changes can require separate approvals.For residents, however, ongoing construction means noise and disruption in a neighbourhood known for its residential appeal. With permits still appearing in city records, the project has become a long-running feature of life on El Camino del Mar.
