Initial analysis

The three-unit, three-story multi-family residential building at 3635-3639 25th Street in Noe Valley, owned by Lui Ping Yu & May Ling Lee, was constructed in 1905. The building's history reveals several maintenance and compliance issues over the years, with the most significant cluster of violations occurring in September 2001, when multiple citations were issued regarding fire safety and building maintenance, including problems with combustible storage, egress obstruction at the rear door, and stair repairs. These violations were subsequently abated by October 2001. A more recent concern emerged in March 2011 regarding an exterior wood utility ladder at the top landing of the rear exterior stairway, which was addressed through permit #201103282904 to remove the wooden ladder, completed in March 2011.

The property has undergone routine inspections, with the most recent significant maintenance issue being addressed in 2022, when a missing side sewer vent cover was reported and resolved by October 2022. The building's location has experienced several parking-related incidents, with multiple driveway blocking complaints recorded between 2018 and 2024, all of which were resolved through parking enforcement intervention. Additionally, there have been two instances of overgrown tree complaints that were addressed through tree maintenance services in 2017 and 2022. The overall history suggests that while the building has faced several code compliance issues in the past, particularly in 2001, these have generally been addressed promptly, with the most recent building-related concerns being relatively minor.

Risk rating

How 3635-3639 25Th 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.
