Initial analysis

The property at 4345-4347 California Street is a three-story mixed-use building located in San Francisco's Inner Richmond neighborhood, constructed in 1909 and containing 4 residential units owned by Sebastian F Colabianchi Fml. The building has undergone several significant maintenance and accessibility improvements over the years. Most recently, in June 2023, work commenced on a $15,000 project to improve accessibility at the main entry step with a curb ramp and level landing, continuing the property's commitment to accessibility upgrades after previously addressing ADA compliance with a new entrance aluminum door. The building had a notable period of maintenance issues in 2016, when multiple violations were documented in May, including problems with weatherproofing, lead paint hazards, heating deficiencies, and fire safety equipment, all related to a leak under the kitchen sink that caused water damage and mold. However, all these violations were addressed and abated by August 2016. Additional improvements since then include the replacement of a floor furnace in 2016 and reroofing work completed in 2003.

Recent activity at the property has primarily consisted of normal neighborhood maintenance issues, with multiple 311 calls in 2024 regarding street cleaning, abandoned vehicles, and parking enforcement. These cases involved issues outside the building itself, such as nearby sidewalk cleanliness and curb maintenance. A fire safety complaint about blocked exits was filed in December 2015 but was found to have "no merit" in January 2016. The current state of building permits and recent maintenance history suggests that while the property experienced significant maintenance challenges in 2016, these issues were promptly addressed and no major violations or complaints have been recorded in recent years, with the focus now shifting to accessibility improvements.

Risk rating

How 4345-4349 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.
