Initial analysis

The three-unit residential building at 933-937 Vallejo Street in Russian Hill, owned by Mark & Elaine Bonn, is a three-story structure built in 1908 classified as flats & duplex. The property has undergone several significant improvements in recent years, most notably a comprehensive renovation in 2022 that included kitchen and bathroom upgrades with associated electrical and plumbing work, totaling $35,000. This work was completed in October 2022 and included the installation of new fixtures and updating of electrical systems in multiple units. The building has a history of electrical issues, with documented complaints in 2008 about power outages and circuit breaker problems when the heating system was used, though these seem to have been addressed in subsequent improvements. Other notable historical improvements include the installation of a garage opening in 2006 (costing $10,000), though some associated electrical work permits from that period are recorded as expired.

The building's maintenance history shows regular inspections and prompt attention to violations, with issues being addressed in a reasonable timeframe. A 2001 violation was promptly abated within one month regarding storage of items along rear stairs. More recent 311 complaints have primarily related to external issues rather than internal building problems, including reports of noise, abandoned vehicles, and general cleaning matters, with the most recent complaint being for excessive noise filed in September 2024, which remains open. The property has undergone routine housing inspections in 1999, 2001, and 2004, all of which were resolved. Multiple street space permits were issued between 2005-2007, indicating various authorized uses of the street area, though the specific purposes are not detailed in the records. While the building has experienced various maintenance and compliance issues over the years, recent improvements and prompt response to violations suggest an actively managed property, with no major safety concerns or persistent problems noted in recent years.

Risk rating

How 933-937 Vallejo 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

Out of 1133 buildings in this neighborhood, 147 are predicted to be safer.
