Initial analysis

The two-unit residential building at 4814-4816 California Street is a 2-story flats and duplex structure built in 1924, currently owned by Joe J & Tina E Han. The property's maintenance record shows a reroofing project completed in 2011 at a cost of $7,000, and a street space-related permit issued in 2018 with a nominal cost of $1. While the building's structural permits are minimal and appear generally routine, there have been multiple infrastructure-related issues on the surrounding street, particularly in 2021 when four separate pavement defect reports were filed (one transferred to another department), indicating some ongoing concerns with the roadway surface.

Recent service requests from city agencies reveal a pattern of maintenance issues in the vicinity, particularly relating to street cleanliness and waste management, with several reports of overflowing garbage cans and loose debris on the streets in 2023-2024. A sign repair request from December 2023 remains open regarding a leaning permit parking sign. The most recent incident occurred in January 2025 involving a sidewalk parking violation that resulted in a citation, suggesting ongoing challenges with enforcement of parking regulations in the area. The building's documented history does not reveal any serious safety concerns or structural issues, and the maintenance work performed appears to be standard for a building of its age.

Risk rating

How 4814-4816 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

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