Initial analysis

1141 South Van Ness Ave is a 10-unit, 2-story multi-family residential building located in San Francisco's Inner Mission neighborhood, built in 1863 and currently owned by Chaudoir Family Trust. The building has experienced several significant events over its recent history, most notably a fire incident in 2011 that caused damage requiring substantial repairs to both lower and upper units, including drywall replacement, insulation installation, and exterior work totaling approximately $20,000. The property has faced ongoing maintenance challenges, with multiple complaints and violations from 2021 to 2023 regarding plumbing issues, including flooding and tub/shower repairs, as well as concerns about building safety systems. Recent fire safety issues were documented in September 2024, including blocked exits and problems with fire extinguishers, though these were subsequently corrected. The building has also had historical issues with water damage, insects, and general maintenance needs as evidenced by 2022 complaints. Infrastructure work has been performed periodically, including reroofing efforts in 1993 and 1996, stair repairs in 2009, and various electrical and plumbing improvements. Regular fire safety inspections have identified various minor violations over the years, including issues with alarm systems and blocked exits, though most have been promptly addressed.

The building's recent history from 2021 to 2024 shows ongoing maintenance and safety concerns, with the most pressing issues being related to plumbing and fire safety systems. Three notable complaints were filed in March 2023 regarding gas utility shutoff tools, safety compliance, and fire protection systems, while earlier complaints in 2021 involved flooding and bathroom issues. A comprehensive complaint filed in February 2022 documented conditions across all units including lack of hot water, insects/rodents, and mold. The building's maintenance record shows regular attention to repairs and improvements, but also indicates recurring issues with building systems and infrastructure.

Risk rating

How 1141 South Van Ness 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.
