Initial analysis

The 12-unit, three-story multi-family residential building at 6026 California Street, owned by Rosano Properties LLC, was constructed in 1964 and has undergone several significant improvements over recent years. Most notably, the building has received substantial fire safety upgrades, including a fire alarm system upgrade in 2023 costing $54,200, followed by further fire alarm work completed in 2024 ($14,391). The property has also seen major maintenance work including a full reroofing in 2021 ($64,880) and the comprehensive replacement of 48 windows and 6 patio doors in 2021 ($104,000). In 2011, the building underwent important seismic strengthening work at the ground floor, adding moment frames and shear walls ($40,000).

The building's maintenance history shows regular attention to safety systems, particularly the fire alarm infrastructure, which has required multiple upgrades since 2006, including four documented alarm system complaints that were promptly addressed and corrected. The property has experienced some historical violations related to fire safety in 2006, including issues with smoke enclosure doors, exterior door locking mechanisms, and a fire escape ladder, all of which were resolved by January 2007. Recent activity at the property includes three 311 call complaints in 2024 related to construction equipment, street cleaning, and sewer service, as well as multiple street defect reports and noise complaints. The building's fire safety systems received two inspections in late 2024 (October - Sprinkler/Standpipe Systems and Extinguishers), with the latter being noted as having "No Merit" upon resolution.

Risk rating

How 6026 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
5th percentile

Out of 660 buildings in this neighborhood, 627 are predicted to be safer.
