Initial analysis

The three-story, 5-unit apartment building at 593-595 Potrero Avenue in Potrero Hill, built in 1911 and currently owned by Young Family Trust A, has a complex history of maintenance and compliance issues. Most recently, the property has experienced recurring issues with garbage overflow, with ten documented incidents between December 2024 and January 2025. The building has undergone several significant renovations and repairs over the past decade, including a $35,000 kitchen and bathroom remodel in 2019 (with associated plumbing and electrical work), a rooftop replacement in 2015, and various interior improvements in 2006 including window replacements and bathroom renovations.

However, the property also has multiple unresolved compliance issues dating back to 2004. These include violations related to lead paint hazards, broken windows, damaged weatherproofing on siding, plumbing issues, and security concerns such as inadequate door locks. There are also active complaints from 2009 and 2011 regarding unauthorized construction work and fire damage to the garage roof. More recent concerns include a 2023 complaint about a gas line modification without the proper permits and an active 2007 complaint about inadequate lighting and plumbing issues that remains unresolved. The building's maintenance history shows consistent efforts to address various infrastructure needs, though many of the most pressing safety and compliance issues remain outstanding more than 20 years after being first documented.

Risk rating

How 593-595 Potrero 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.
