Initial analysis

The two-unit multi-family residential building at 3739-3741 Geary Blvd, owned by David Tsao, has experienced several significant issues over the past few years. Most notably, between 2021-2024, there were multiple violations related to unauthorized construction work involving a 10-foot fence against a neighboring building, including improper fastening to the neighbor's siding and window casings. This situation prompted three consecutive building permits (202301049674, 202402135807) to remove temporary structures and comply with notices of violation, with costs totaling $1,100. The building has a history of sewer-related issues, with multiple service requests between 2018-2023 documenting sewage backups and vent problems, particularly during 2018 when there were several consecutive incidents requiring multiple interventions. There was also a complaint in 2022 regarding unauthorized modifications to the vacant storefront, including illegal signage and transparency requirement violations, though this complaint is currently listed as not active. The property has undergone various permitted improvements over the years, including a horizontal addition (1988), gas line installation for restaurant outlets (2010), and electrical work (2006).

The building's mixed-use classification (residential and commercial) has led to various regulatory interactions, including permits for restaurant use and ABC license applications. Recent maintenance activity includes an issued permit in 2024 for skylight repair at a single-family dwelling, though this may reference a related or adjacent property. The property has experienced recurring sewer infrastructure challenges, particularly evident through multiple 311 calls in 2018 documenting similar issues, suggesting potential ongoing plumbing system concerns. While there have been several resolved violations and completed permits, the pattern of recent compliance-driven permits (2023-2024) indicates ongoing efforts to address and rectify building code compliance issues. The building's age (constructed in 1922) and history of both residential and commercial use suggest a complex maintenance and regulatory compliance history, with the most pressing recent issues primarily related to unauthorized construction and safety compliance.

Risk rating

How 3739-3741 Geary Blvd's risk score is calculated
