Initial analysis

Located at 2433 Larkin Street in Russian Hill, this two-story, 5-unit multi-family residential building, owned by Gerald J & Juliann T Demart, has undergone significant maintenance and improvements since its construction in 1950. Most notably, the building completed a mandatory soft-story retrofit in 2016 (at a cost of $40,000), demonstrating compliance with seismic safety requirements. The property has seen consistent unit upgrades, particularly in kitchen modernization, with renovations documented in Units 1 through 5 between 2008 and 2016, often including electrical and plumbing updates. Energy efficiency improvements include window replacements (2017), attic insulation installation (2018), and multiple furnace upgrades (2013 and 2016).

The building had a serious structural issue in 2003-2007 regarding a retaining wall showing signs of movement and potential failure, which required engineering reports and work to address the problem, though this has since been resolved. Several maintenance tasks were performed, including a $20,000 repair of the rear concrete patio in 2015. The property has undergone regular housing inspections, with no recent active violations. There has been one minor fire incident involving a smoke detector activation with no fire or injuries recorded. The building's parking area has experienced recurring issues with blocked driveways, as evidenced by multiple parking enforcement calls between 2019 and 2024, though these do not directly impact building conditions.

Risk rating

How 2433 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

Out of 1133 buildings in this neighborhood, 612 are predicted to be safer.
