Initial analysis

This three-story, six-unit multi-family residential building constructed in 1955 has undergone several significant safety and maintenance upgrades in recent years, with the most current major work involving a fire system replacement and new sounders installation in July 2023 to comply with updated fire codes. In 2020, the property received improvements including the installation of 10 aluminum windows to replace vinyl ones while maintaining historical accuracy, along with electrical system updates that moved sub-panels from closets to hallways in all six units and replaced outdated fuse disconnects with modern breakers. The building has experienced recurring fire safety concerns, most notably a series of violations in 2006 related to fire escape maintenance, smoke enclosure doors, and fire proofing, though all these were eventually abated. A hoarding violation was recorded and resolved in 2019, and another fire-related issue regarding improper storage of combustible materials was also addressed that year.

Recent tenant complaints include a no hot water issue reported in May 2024 and concerns about unsafe drilling near foundations in February 2020, while building systems were historically inspected for various safety compliance matters in 2000-2006. The property has generated multiple 311 calls since 2023, primarily regarding street cleaning and parking enforcement issues in the vicinity, though these are external to the building itself. The building's fire safety systems were briefly addressed in mid-2024, with a correction made to unspecified conditions, indicating ongoing attention to fire safety matters. The building's ownership structure is currently held under the Connie Der Survivors Trust.

Risk rating

How 5540 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
