Initial analysis

The three-story, two-unit multi-family residential building at 2141 Pacific Avenue in Pacific Heights, owned by Tan Tian Hong, has been in operation since 1900 and has undergone several significant maintenance and improvement projects over the years, including multiple roofing jobs (completed in 1990 and 2004 at costs of approximately $20,000), bathroom renovations in 2015, and sewer line repairs in 2018. However, the building is currently facing serious and multiple active building violations as of September 2023, with a director hearing scheduled for January 18, 2024. These violations include lack of proper heating systems, missing smoke and carbon monoxide detectors, unsafe gas appliance usage, inadequate window maintenance, and several safety concerns regarding handrails, fire extinguishers, and furnace/water heater access. The building has also failed to file its annual unit usage reports consistently from 2019 through 2023, with the most recent complaint about non-filing appearing in March 2024.

Recent tenant complaints have centered around HVAC issues, broken windows, ventilation problems, and problematic heating systems. A notable pattern of complaints regarding heating and ventilation systems emerged between 2023 and 2024, with one complaint in September 2023 specifically mentioning concerns about cooking odors and ventilation problems affecting multiple units. Outside the building, there have been recurring issues with parking violations and sidewalk maintenance, though these are less directly related to building conditions. The most recent fire incident on record was a false alarm or call, occurring with no civilian injuries reported. The property has maintained some basic safety features over time, including the installation of emergency lights and exit signs in 2007, though many current violations suggest that systematic maintenance or upgrading of safety systems has been lacking in recent years.

Risk rating

How 2141 Pacific Ave'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.
