Initial analysis

Located in Nob Hill, this 6-unit, 3-story multi-family residential building was constructed in 1912 and is currently owned by Lauren Irene Chue Wong. The property has undergone several significant upgrades and faced multiple challenges over the years. Most notably, the building completed a mandatory soft-story retrofit in 2017 (cost: $70,000), demonstrating compliance with seismic safety requirements. Recent maintenance includes 2024 repairs to the lightwell stair and exterior steps, along with plumbing work in 2023 for a new console heater installation. The building has a documented history of heating system issues, with multiple complaints about heat and hot water problems particularly concentrated between 1994-2002 and a significant cluster of violations in December 2015 when there were widespread utility shutoffs affecting heat, hot water, and common area lighting. These 2015 issues resulted in multiple housing violations that were subsequently resolved.

The property has experienced periodic infrastructure improvements, including the 2017 water line replacements in Apartment #6, 2016 back stairway lighting installations, and electrical service upgrades in 2005. Importantly, the building underwent fire safety improvements, completing all requirements of the 2017 soft-story seismic retrofit program and maintaining fire alarm systems, though there were some false alarm incidents recorded. The building's maintenance history shows attention to structural elements, including dry rot repairs in 1994, though there have been sporadic issues with building systems requiring attention, as evidenced by the series of 311 calls and complaints regarding various maintenance matters. The recent plumbing work, completed in 2023, suggests ongoing investment in building systems. While there have been multiple historical violations and complaints, most of these have been addressed and are no longer active, with the most recent documented building improvements focusing on safety and infrastructure maintenance.

Risk rating

How 1831 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
