Initial analysis

The property at 4308-4310 California Street is a two-story, multi-family residential building with ground floor commercial space, constructed in 1908. The building has experienced several significant maintenance and structural issues in recent years, particularly relating to water damage and mold problems. From late 2023 through 2024, there have been multiple water-related complaints, including persistent leaks through light wells affecting both residential and commercial spaces, with tenants reporting ongoing water pooling issues. The property has undergone several repair efforts during this period, including re-roofing work in late 2023 and repairs to dry rot damage, though some of this work was performed without proper permits, leading to violations that were subsequently addressed.

The building's maintenance history shows attention to various systems, including bathroom renovations, electrical work, and plumbing updates, though some projects have encountered issues. In mid-2024, there was a concerning complaint regarding pests (rats and flies) and structural integrity issues with interior walls. Additionally, there have been documented tenant-landlord disputes, particularly regarding construction work and property management interactions in 2024. The property has an approved but not executed permit proposal to extend the ground floor commercial space and add two residential units, though this would be a significant increase in density without any proposed parking spaces. Recent building permits indicate ongoing maintenance efforts, including addressing violations and performing necessary repairs, with the most recent work completed in September 2024.

Risk rating

How 4308-4310 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.
