Initial analysis

The 2-unit residential building at 165 12th Avenue, owned by the Chang/yu Family Trust, is a 3-story duplex constructed in 1983 in the Lake --The Presidio neighborhood. The property has undergone several significant improvements over the past three decades, including two major window replacement projects - one in 2004 for 20 vinyl windows facing the street (permit expired) and another in 2007 for 10 vinyl windows not facing the street, which was successfully completed and featured energy-efficient double-pane construction. The building has also received attention to its roofing, with completed reroofing projects in 1991 and 2003 costing $11,288. In 1992, the property underwent a legalization process for two guest rooms and storage, and there were earlier attempts to address this in 1991, though one of those permits was cancelled.

Recent history shows a pattern of parking-related issues near the property, with multiple complaints about driveway blocking between 2018 and 2023, including incidents involving various vehicles that were generally resolved through enforcement action. The building's surroundings have experienced occasional maintenance challenges, such as reports of graffiti (2018), an overgrown tree near communication lines (2018), and waste on public property (2019-2021), all of which were addressed through appropriate municipal channels. One notable infrastructure issue occurred in July 2014 involving a sewage backup that was promptly resolved by the PUC Sewer Operations. The building's maintenance record suggests regular upkeep, with significant investments in windows and roofing over the years, though some attempted improvements (such as the 1991 window replacement and guest room legalization permits) either expired or were cancelled.

Risk rating

How 165 12Th Ave'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
