Initial analysis

The two-unit residential building at 174 Lexington Street in the Inner Mission, owned by Dela Cruz Nieves, has a concerning history of safety and maintenance issues since its construction in 1908. Most notably, there was a significant incident in February 2021 when the rear egress staircase collapsed while firefighters were responding to a fire, revealing major structural deterioration. This was followed by multiple active violations including rodent infestation, electrical outlet issues, obstructed egress, and accumulation of rubbish or trash, with all these violations still showing as active since November 2021. The building underwent some improvements with the installation of a new furnace in 2014 and an electrical service upgrade in 2018 that included two meters and panels, indicating efforts to address basic infrastructure needs.

Historical complaints suggest persistent habitability issues, including reports of illegal unit conversions, hoarding, and serious safety concerns such as fire hazards, lead paint risks, water damage, and inadequate smoke detection systems. The property was previously cited for being overcrowded in 1994, with multiple families occupying the building under unsafe conditions. More recent activity around the property has been documented through 311 calls, mainly involving parking violations and sidewalk maintenance issues, though these are not directly related to the building's structural or habitability concerns. The accumulation of violations and history of emergency incidents raises significant concerns about the building's maintenance and safety systems, particularly regarding egress and fire safety.

Risk rating

How 174 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.
