622-624 Haight St, San Francisco, CA 94117

The property at 622-624 Haight Street is a two-story, multi-family residential building constructed in 1895, currently owned by 437 Duncan St LLC. The two-unit building has undergone significant improvements and safety upgrades over recent years, with the most substantial work occurring in 2021, including the installation of a new monitoring fire alarm system ($5,806), complete rewiring of the first floor unit with added laundry facilities, and bathroom renovations.

Compliance with modern safety standards has been a focus, with the installation of fire sprinklers throughout the ADU unit in 2019 ($12,700), foundation upgrades in 2018, and various plumbing improvements including new shower installations and bathroom remodels. The building has experienced several notable issues in its recent history, though many have been addressed through subsequent improvements.

A complaint from 2017 reported multiple concerning conditions including unauthorized plumbing work and concerns about water heater installations, which appeared to have been addressed by the time of subsequent permits. The property has maintained active responses to infrastructure and system upgrades, evidenced by the recent 2024 work regarding tree root issues affecting the sidewalk, and multiple parking violations in the vicinity have been documented through 311 calls, particularly related to sidewalk parking. Recent complaints primarily relate to exterior maintenance matters, such as garbage management and graffiti, suggesting that the most critical internal safety and habitability issues have been largely resolved through the extensive renovation work carried out between 2018 and 2021.
