Initial analysis

The two-story, four-unit residential building at 555-561 Guerrero Street, built in 1906, has experienced several significant events, most notably a fire incident in April 2015 that led to substantial repairs in 2016 including kitchen and bathroom remodels ($68,400) and electrical upgrades (14 lights, 14 switches, smoke detectors) along with plumbing work. The building has undergone various infrastructure improvements over the years, including gas line work in 2022, water heater and gas line repairs in 2015, and multiple structural repairs. In 2004, the property faced multiple housing violations requiring corrections to stringers, posts, and various interior surfaces including damaged paint, walls, and floors, all of which were abated by September 2004.

More recent concerns include an illegal unit complaint filed in 2017 and multiple garbage and debris reports in late 2024. The building's maintenance history shows regular attention to safety systems, including smoke detector installation and stairway repairs, though there have been some periods of unresolved issues, particularly regarding hot water supply in 2008 and various interior maintenance matters. The property has maintained active compliance with building codes since the significant repairs in 2016, though the recent pattern of 311 calls regarding debris and street maintenance in 2024 suggests ongoing external maintenance needs.

Risk rating

How 555-561 Guerrero 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.
