Initial analysis

The multi-family residential building at 257-259 Andover Street in Bernal Heights is a two-story structure built in 1906, containing three units and classified as Flats & Duplex. The property has experienced several significant safety and maintenance issues over the past decade, with the most pressing concern being an active complaint filed in February 2024 regarding potentially collapsing rear stairs that have reportedly blocked egress for second and third-floor units. This recent permit activity shows the owner has filed to replace decks on two levels and completed a $30,000 project to replace a three-story wooden staircase and landings in January 2024, suggesting recognition of the critical nature of the building's access issues. The property has a history of stairway-related problems, with multiple repairs documented between 2007-2024, and has undergone several major works including a sewer house trap replacement in 2020, an electrical service upgrade in 2007, and multiple roofing and exterior maintenance projects.

The building has faced various violations and complaints over its history, particularly related to safety and maintenance concerns. In 2022, there were violations regarding weatherproofing and lead paint security on the siding, while in 2013-2014, there were documented issues with roof maintenance where pieces reportedly fell during strong winds. Other historical concerns included pest infestation, handrail repairs, door lock replacements, and various interior surface maintenance needs, with many of these violations being documented and abated by September 2022. The property has undergone several structural improvements and repairs over the years, including kitchen and bathroom remodeling, installation of aluminum siding, and multiple staircase renovations, indicating ongoing maintenance efforts by the current ownership under Richard S. Kaihara Trustee. Recent activity shows continued responsiveness to structural concerns, though the presence of recent complaints about blocked egress suggests that some safety issues remain to be fully addressed.

Risk rating

How 257-259 Andover 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.
