Augrented Insights Report

The 23-unit, 4-story apartment building at 735 O'Farrell Street in the Tenderloin, owned by 735 Ofarrell 17 Lp, has undergone extensive renovation work in recent years. Between 2021 and 2024, multiple units (21, 22, 24, 36, and 42) received significant upgrades including kitchen and bathroom rehabilitation, closet conversions, and washer/dryer installations, with associated costs ranging from $12,000 to $60,000 per unit. The building has also faced several maintenance and safety challenges, particularly concerning fire safety systems, with violations recorded in 2023 (alarm systems), 2022 (sprinkler systems), and 2017 (multiple fire code violations).

More recently, there have been documented mold issues in 2023, primarily related to inoperable windows affecting ventilation, and earlier water damage complaints in 2015-2011. The property has a history of compliance issues, as evidenced by multiple building complaints and violations. In 2015, there were complaints about unauthorized work in Unit 34, while soft-story retrofit compliance was questioned in 2016.

The building's infrastructure has received attention, with permit work in 2024 involving the removal of fire sprinkler heads from an unused garbage chute. Regular maintenance and upgrading of individual units have been ongoing, with plumbing and electrical permits showing consistent modernization efforts. The building's systems have experienced various incidents, including a gas leak and multiple cooking-related fire incidents, though with no reported civilian injuries. The property has also generated numerous 311 calls regarding exterior conditions, including reports of garbage, encampments, and public health concerns in the surrounding area, particularly evident in recent months (2024).
