735-739 Clay St, San Francisco, CA 94108

The three-story multi-family residential building at 735-739 Clay Street, constructed in 1907 and owned by Kwong Sang Investment LLC, contains four units and includes both residential and commercial space. The property has undergone several significant safety improvements, including a seismic retrofit in 2001 costing $30,000, and has had multiple fire safety-related incidents and violations, particularly notable in recent years.

The building experienced three separate fire code violations between 2017-2023, including issues with fire extinguishers, alarm systems, and exit maintenance, though all were subsequently corrected or abated. The property has also faced irrigation and maintenance challenges, as evidenced by multiple 311 calls regarding garbage, debris, and graffiti between 2024-2025.

Two notable planning records include an illegal short-term rental case from 2023 that was resolved prior to the issuance of any formal notice and a conditional use authorization request regarding unit merging from 2023 that was ultimately cancelled. Two fire incidents were recorded - one at 744 Clay Street with detector activation and another at 735 Clay Street with a malfunctioning alarm system, neither resulting in civilian injuries.
