Initial analysis

The property at 129 Lexington Street is a three-story, four-unit multi-family residential building constructed in 1962, currently owned by Gerson/shiu-gerson Fmly Rev. The building has undergone several significant improvements and faced various challenges over its history. In the early 2000s, the property underwent major renovations including the installation of a fire sprinkler system ($27,600) in garage and living areas in 2006, reconfiguration of interior layouts in 2005, and a substantial renovation in 2004 that reduced the unit count from five to four. A significant cluster of building violations was recorded in October 2003 related to fire safety, smoke detection, and interior surfaces, though these were all abated by January 2004. The building's history includes multiple complaints from the late 1990s through early 2000s regarding various maintenance issues, including a serious complaint in 1997 about unsanitary conditions, mold, broken windows, and heating problems, along with gas-related concerns.

The property has maintained compliance with building codes since the major violations were addressed in 2004, and recent improvements have focused on maintenance and safety upgrades. Recent 311 calls (2023-2024) primarily concern external issues such as sidewalk cleaning and graffiti, though these are not building-specific problems. The property underwent a dwelling unit merger process with mandatory Design Review, which was approved. A fire violation was recorded in December 2008 related to exits/fire escapes, though there are no active fire safety concerns on record. Recent inspections and maintenance work suggest ongoing attention to building upkeep, though the pattern of maintenance issues in the late 1990s and early 2000s indicates there was a significant period requiring substantial improvements to meet housing codes and resident needs.

Risk rating

How 129 Lexington 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
