Initial analysis

The 6-unit residential building at 929-933 Scott Street in Alamo Square, owned by Sandra Ma Lee 2009 Revoc Tr, is a three-story apartment building constructed in 1904. The property has undergone several significant safety upgrades in recent years, most notably a comprehensive fire alarm system upgrade completed in 2022-2023 that included the installation of new smoke detectors, pull stations, wall-mounted horn strobes, sounders, and related equipment to comply with San Francisco Fire Code requirements. Additionally, essential infrastructure work was completed in early 2023 with the replacement of 12 feet of sewer pipe and a house trap.

Of particular concern is an active complaint from November 2020 indicating that the building, identified as a multi-unit soft-story structure, had not been added to the city's soft-story property mandate, suggesting potential seismic vulnerability. The property has a history of multiple building violations, particularly in late 2002 and 2009, including issues with fire safety, security requirements, and general maintenance, though all of these violations were ultimately abated. More recently, the building has generated numerous parking enforcement calls between 2023-2024, primarily related to vehicles blocking driveways, though these incidents are generally considered separate from the building's residential conditions.

Risk rating

How 929-933 Scott 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.
