Initial analysis

The three-story multi-family residential building at 551-555 Ivy St in Hayes Valley, owned by Aaron Koblin and constructed in 1909, contains three units and has undergone several significant renovations over the past decades. Most recently, building systems updates have included the installation of a direct vent heater in 2021, while prior improvements in 2009 encompassed a major interior remodel of Unit #555, including kitchen and bathroom updates, and the replacement of partially removed exterior stairs. The property has experienced recurring fire safety issues, with numerous violations and complaints regarding fire extinguishers, including three separate violations between 2023-2024 that required correction, and multiple fire extinguishing system problems noted in 2019 and 2024. A cluster of building code violations was documented in 2018 related to fire safety equipment, and historical violations from 2008 included various security and building requirements, all of which were officially abated by May 26, 2011.

The building has undergone several routine safety inspections over the years, with significant findings related to fire safety equipment, including fire extinguisher maintenance, smoke detector installation requirements, and general building safety compliance. The property has seen various maintenance and improvement work, including structural revisions in 2010 and utility system upgrades in 2009. Recent 311 calls from 2023-2024 indicate ongoing challenges with exterior maintenance and street conditions around the property, though these are primarily external to the building itself. While the building has had multiple violations over the years, records indicate that most issues have been resolved, with only one open violation related to sleeping area requirements from November 2023 requiring permit correction as of May 2024.

Risk rating

How 551-555 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.

Grade D–F — High risk

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