Initial analysis

The property at 143-145 15th Avenue is a two-unit residential building located in the Lake--Presidio neighborhood, owned by the Robert Y Chin Trust and constructed in 1961. The building has undergone several significant improvements over the past few decades, with the most substantial being a comprehensive remodel in 2015 that included updates to the kitchen and both bathrooms, alongside new electrical work (installation of lights, switches, fans, and appliances) and plumbing fixtures, with a reported cost of $44,000. Earlier maintenance included window repairs in 2003 and reroofing work in 1988.

The building has experienced multiple maintenance issues, particularly in the early 2000s and in 2013. In 2003, there were violations related to interior surfaces, including damaged walls and concerns about lead-based paint, which were addressed by April 2003. A 2005 complaint regarding water damage and plumbing issues was resolved within six months. The most recent significant complaint from 2013 involved problems with the kitchen appliances, flooring, and ventilation. Since 2018, there have been no recorded building code violations or major complaints. The property has had multiple parking-related incidents in recent years, with several citations issued for driveway blocking and sidewalk parking between 2019-2024, though these are not directly related to building maintenance or habitability concerns.

Risk rating

How 143-145 15Th 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.
