Initial analysis

The two-unit residential building at 557-559 Ivy Street in Hayes Valley, owned by Gabbac Leoncio S, was constructed in 1924 and is classified as a Flats & Duplex. The property has undergone several significant improvements and faced some safety compliance issues over the years. In 2009, the building addressed a violation regarding a prohibited wooden fixed utility ladder, with the removal work completed by March of that year. A notable renovation took place in 2008 for unit 559, involving a comprehensive kitchen remodel that included cabinet replacement, countertop installation, plumbing fixtures updates, and electrical improvements, with a total cost of approximately $15,783. This renovation was accompanied by proper electrical and plumbing permits, including the installation of new kitchen appliances and fluorescent lighting upgrades.

The building has experienced multiple fire alarm system activations throughout its history, with the most recent incidents occurring in 2022 and 2023, though all were attributed to system malfunctions and were promptly corrected. Other notable incidents include a 2013 elevator rescue and several medical assists that required EMS crew support, none of which resulted in civilian injuries. The property has faced recurring maintenance challenges, as evidenced by recent 311 calls between September 2024 and January 2025, primarily related to garbage and debris issues on the street, including multiple instances of abandoned furniture and loose garbage. While these exterior maintenance concerns have been promptly addressed by city services, they suggest ongoing challenges with waste management in the immediate vicinity of the building.

Risk rating

How 557-559 Ivy 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.

Elevated violation and complaint history. DBI has found issues here before and is statistically likely to again.
