Initial analysis

This three-story, six-unit multi-family residential building at 531 Guerrero Street in the Mission Dolores neighborhood, built in 1924, has undergone several significant renovations and faced various maintenance issues over its history. Most recently, in 2022, the building completed a $35,000 window and rear porch renovation project and a comprehensive $40,000 remodel of apartment 6, which included kitchen and bath improvements, electrical rewiring, and the installation of a tankless water heater. Prior improvements include a mandatory $55,000 soft-story seismic retrofit completed in 2018, demonstrating compliance with city safety requirements.

The building has experienced recurring water-related issues, particularly affecting unit 6, with complaints in 2012-2015 about leaks, ceiling damage, and window problems. Multiple violations between 2002 and 2012 raised concerns about fire safety and building maintenance, including fire escape ladder maintenance, lead paint hazards, and interior surface conditions, though all were resolved. A 2022 complaint regarding unauthorized work in apartment 6 was promptly addressed through the proper permitting process. The property's more recent history (2018-present) shows improved maintenance and compliance, with no active violations or complaints on record since 2022. Regular street cleaning and waste management issues have been documented through 311 calls, primarily relating to public sidewalk maintenance rather than building-specific concerns.

Risk rating

How 531 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.

Neighborhood percentile

Out of 799 buildings in this neighborhood, 503 are predicted to be safer.
