Initial analysis

The two-unit multi-family residential building at 786-788 30th Avenue in the Central Richmond neighborhood, owned by the Cyrene Liang Revocable Trust, was constructed in 1929 and features two stories. The property has undergone several significant upgrades in recent years, with major electrical work completed in 2020-2021 including a comprehensive upgrade to 400-amp service, installation of new meter panels, and replacement of electrical outlets throughout the building. In 2021, bathroom renovations were completed including fixture replacements and electrical upgrades, along with the replacement of wall heaters. The building experienced heating system deficiencies in late 2021-2022, leading to multiple complaints filed with Housing Inspection Services regarding inadequate heat to occupied habitable rooms, with the most recent complaint filed in December 2022 and officially abated by February 2023.

Earlier improvements to the property include work completed in 2008 for the installation of 18 retrofit windows (though this permit expired), and reroofing work completed in 1990. The building has been subject to several parking-related issues in recent years, with multiple complaints about blocked driveways recorded between 2019-2024, including three instances of enforcement action taken in August and September 2024. The property had two sewer-related incidents in 2019, which were addressed by PUC Sewer Operations. A false fire alarm was recorded, though no injuries were reported, and the building has not been involved in any tenant buyouts according to available records.

Risk rating

How 786-788 30Th 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.
