Initial analysis

The three-unit multi-family residential building at 135 Lexington Street in the Inner Mission, owned by Mak John Yuhong & Chen Xun, has a notable history dating back to its 1906 construction. The building's records show an early housing violation from January to April 1995 regarding an illegal downstairs unit, though this issue was eventually abated. More recently, there have been recurring concerns about sidewalk management and public cleanliness in the immediate vicinity, with multiple 311 calls between 2022 and 2024 primarily related to parking violations on sidewalks and various street cleaning needs including reports of waste, garbage, and debris. The most recent incidents in 2024 involved blocked sidewalks and parking violations, though these were either not found upon inspection or resulted in citations. The building's safety systems have been test-activated twice, though neither incident involved actual fires or resulted in civilian injuries. While the property itself does not appear to have any recent violation history, the surrounding area has experienced persistent challenges with street maintenance and parking enforcement as documented through multiple 311 calls over the past two years.

Risk rating

How 135 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.
