AI summary

The three-unit, three-story multi-family residential building at 2146-2150 Larkin Street in Russian Hill, built in 1906 and currently owned by 2146 Larkin Street LLC, has experienced several maintenance and safety issues over the past few decades, with the most immediate concerns centering around sewer problems. Recent incidents include multiple sewage discharge issues in 2024 (December and October), flooding on the property, and sewer back-up problems. In 2023, there was a report of tree root damage to the sidewalk. The building has a history of maintenance improvements, with records showing various renovations including termite treatment in 2005, window replacements in 1986, and interior improvements in 1990 including a kitchen/bath remodel and closet modifications.

The property underwent two notable routine inspections in the early 2000s (2001 and 2003) that identified several safety concerns, particularly relating to fire safety and stairways. These inspections revealed issues with combustible storage, egress obstructions, inadequate lighting, and tripping hazards on rear stairs, though all these violations were abated by August 2001. While most historical building violations have been resolved, the recent pattern of sewage-related incidents suggests ongoing infrastructure challenges. The property's response to various 311 calls indicates active management, with most issues being promptly addressed, though some concerns, such as the tree root problem reported in October 2023, remain open.

Risk rating

How 2146-2150 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.
