Initial analysis

The 8-unit, 2-story multi-family residential building at 2439 Larkin Street in Russian Hill, constructed in 1923, has undergone several significant structural and safety improvements over recent years, most notably completing its mandatory soft story retrofit program as a Tier 3 building in February 2021, following a compliance violation issued in October 2019. This seismic retrofitting work, initially planned in 2017 and properly completed in 2019-2020 at a cost of approximately $120,000, involved revising shear wall locations under the guidance of San Francisco's building code requirements. The building's foundation and retaining walls at the rear were repaired in 2014 at a cost of $30,000, and a house trap replacement was completed in late 2013.

The property has maintained a regular schedule of routine housing inspections between 2000 and 2011, all of which were closed with no significant reported issues. While there have been some infrastructure concerns, including a sewage backup incident in 2013 and sewer issues reported in 2022, these were addressed through standard municipal processes. The building experienced three false alarm incidents between 2008 and 2011, none of which resulted in any injuries or actual fires. Regular street space permits have been issued for the property over the years, with the most recent in early 2020. The building's current ownership is held under the Gene B Poon Decedent Trust, as per the latest available records.

Risk rating

How 2439 Larkin 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
