Initial analysis

The two-unit, two-story multi-family residential building at 50 Bay View St, owned by Shu Zhen Tripp 2020 Tr, was constructed in 1907 and has experienced several significant maintenance and safety issues over its history. The most critical period was in early 2015 when multiple serious violations were documented, including problems with exterior stairs, windows, lead paint hazards, fire safety concerns, and interior maintenance issues such as mold, cockroach infestation, and plumbing problems. These violations were formally noted in a Notice of Violation (NOV) on February 26, 2015, with compliance deadlines resulting in two building permits for stair repairs costing $6,500, and all violations were ultimately abated by January 19, 2016.

More recent history shows continued maintenance challenges, with a complaint in October 2017 regarding missing smoke alarms and a cracked kitchen window, which followed previous reports of interior and exterior issues. The most recent building-related concerns were documented in complaints from 2023-2024, including a sewage backup in October 2023, sidewalk damage in February 2024, and multiple reports of garbage and debris issues. A building inspection request was made in February 2024, and there was an illegal construction complaint in September 2024, though these issues are documented as resolved or transferred. The property has also experienced exterior maintenance challenges, as evidenced by multiple 311 calls for garbage and debris removal throughout 2024, indicating ongoing concerns with waste management around the property.

Risk rating

How 50 Bay View St's risk score is calculated

We trained a model on 7 years of SF DBI inspection data — notice of violation filings, complaint history, and owner track records. It estimates the probability that DBI inspectors will issue a Notice of Violation at this address in the next 12 months. Lower % = safer.

What the score means for you

Grade A–B — Low risk

DBI rarely finds violations here. Strong maintenance history and a clean complaint record.

Grade C — Moderate risk

Some past violations or complaints on record. Worth asking the landlord about any open issues before signing.

Grade D–F — High risk

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.

Neighborhood percentile
