Initial analysis

The 16-unit, 3-story multi-family residential building at 2930 Lyon Street in Cow Hollow, owned by Waldman Family Partnership, has undergone several significant safety system upgrades and maintenance work since its construction in 1923. Most notably, in 2023, the building has seen substantial fire safety improvements, including an upgrade to the fire alarm system to comply with San Francisco Fire Code requirements in July 2023, installation of a manual and automatic fire alarm system in February 2023, and the replacement of the main electrical distribution system, including the replacement of a Federal Pacific panel, in December 2023. The building has experienced recurring fire safety-related issues, with multiple fire complaints between 2016 and 2021 regarding alarm systems and extinguishers, though all have been marked as "Condition Corrected" or properly abated.

The property has maintained its infrastructure with appropriate upgrades, including the installation of a solar water heater in 2018 and historical records showing reroofing work completed in 1989. A notable building violation was recorded in 2007 regarding self-closing devices on exterior doors, but this was promptly abated within one month. While there have been occasional complaints about heating (1999) and unpermitted construction work (2019), these issues were not persistent. The building's maintenance history shows regular attention to critical systems, particularly fire safety, with recent improvements suggesting ongoing commitment to resident safety. The property has experienced various minor exterior issues documented through 311 calls, primarily related to street cleaning matters rather than building safety concerns.

Risk rating

How 2930 Lyon 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 861 buildings in this neighborhood, 706 are predicted to be safer.
