AI summary

690 Guerrero Street is a 9-unit, 3-story multi-family residential building located in the Mission Dolores neighborhood, owned by Kam/so Trust and constructed in 1927. The property has undergone significant renovations in recent years, with substantial work completed in 2023 including comprehensive bathroom and kitchen renovations in Units 4 and 6 (both costing $55,000 each) featuring new fixtures, electrical systems, and subpanels. In 2021-2022, the building underwent extensive improvements across multiple units (3, 5, 7, 8, and 9) including kitchen and bathroom remodels, electrical system upgrades, and the installation of new lighting, all totaling approximately $250,000. A mandatory Tier 3 seismic soft-story retrofit was completed in 2015, addressing structural safety concerns.

The building has faced several maintenance and safety issues, particularly in 2022-2023, with multiple complaints regarding heating and hot water problems, including a cluster of complaints about lack of hot water in various units during spring 2022. More recent concerns include a water leak reported in March 2024 and a fire extinguisher violation issued in October 2023 (though this was subsequently abated in December 2023). The property has experienced intermittent issues with the entry system security in 2022 and various building systems during the renovation period. While there have been some past problems with fire safety equipment and heating systems, these appear to have been addressed through ongoing maintenance and upgrades. The building's renovation history suggests significant investment in improving living conditions and addressing previous code compliance issues, though some recent complaints indicate potential ongoing maintenance challenges.

Risk rating

How 690 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.
