Initial analysis

The two-unit residential building at 30 San Carlos Street in San Francisco's Inner Mission neighborhood, owned by Tam Hup Hing & Li Fang Zhan, has experienced recurring issues with both parking violations and street cleaning needs over the past two years. Built in 1927, this two-story flats and duplex structure has recorded multiple incidents of driveway blocking, with three documented cases between December 2021 and March 2024, resulting in at least two citations being issued. The property has also faced ongoing challenges with sidewalk maintenance, particularly concerning tree root damage to the sidewalk, which remains an open case as of March 2024.

The building's immediate surroundings have required regular attention from city services, with documented cases of loose garbage and debris requiring municipal intervention on multiple occasions between December 2021 and July 2024. While most of these street cleaning incidents have been resolved, they indicate a pattern of waste management challenges in the area. The most recent incident was recorded in July 2024, pertaining to various types of loose garbage and debris. The property appears to have maintained compliance with housing regulations, as there are no recorded cases of violations or safety concerns directly related to the building structure or systems.

Risk rating

How 30 San Carlos 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.
