Unlock complete report1991 California Street is a 4-story, 18-unit multi-family residential building constructed in 1923, currently owned by Johnson L & Diana W Chiao T. The building has undergone significant renovations and faced several challenges in recent years. Most notably, between 2015-2017, there were multiple complaints and violations regarding heating issues, mold problems, and unauthorized construction work, particularly affecting units 104 and 204. During this period, the building underwent substantial improvements including structural reinforcements, electrical upgrades, and unit renovations. More recent concerns include a December 2023 violation related to sleeping area requirements and a January 2023 issue with sprinkler/standpipe systems, though the latter was corrected in March 2023. The building's mechanical systems have seen extensive work, including multiple boiler permit renewals and heating system upgrades between 2014-2018, as well as plumbing improvements including new water pipes and sewer connections. The property has maintained street space permits through 2017 and underwent significant electrical system modernization in 2016 with a 400-amp service upgrade. While many historical issues have been resolved, including several fire alarm system corrections between 2015-2019, the recent sleeping area violation suggests some ongoing maintenance challenges.

How 1991 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.
Out of 670 buildings in this neighborhood, 536 are predicted to be safer.
