Initial analysis

The two-unit residential building at 4724 California Street, owned by the Tsang Lan Hoy Trust, is a two-story flats and duplex structure built in 1922 in the Lake-Presidio neighborhood. The property has experienced typical urban challenges over the past several years, with the most recent activity being a rent board fee and housing inventory request in October 2024 that was resolved with paperwork to be mailed to the requester. The building's surroundings have seen various municipal service calls, including several street cleaning incidents in 2020-2021, a tree damage incident in March 2021 that was addressed through city-managed tree maintenance, and infrastructure issues such as a pavement defect in April 2019 and a repaired street light in October 2018 due to electrical issues. Other neighborhood concerns have included abandoned vehicles (most recently in September 2023), graffiti removal in March 2017, and isolated incidents of waste that have been promptly addressed by city services.

The building's service record shows timely responses to all reported issues, with each case being officially closed and marked as resolved. The most recent building-specific interaction was the rent board inquiry in October 2024, which represents the only direct resident-related service call in the past three years. While the property has experienced some neighborhood challenges typical of an urban environment, there have been no reported safety incidents directly involving the building itself, and all municipal services have responded promptly to address exterior issues as they arose.

Risk rating

How 4724 California 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
68th percentile

Out of 660 buildings in this neighborhood, 211 are predicted to be safer.
