Initial analysis

The 5-unit, 3-story multi-family residential building at 690 45th Ave, owned by Fannie Ling Hing Chan and constructed in 1948, has experienced numerous maintenance and safety issues in recent years. Most concerning are repeated electrical problems, with multiple complaints between 2020-2024 regarding inconsistent electricity, problems with the electrical fuse box, and more recently, complaints about electrical issues affecting an elderly resident's unit and concerns about a removed automatic garage door opener affecting accessibility for a disabled resident's relative. The building underwent a soft story retrofit in 2017 and had its fire alarm system upgraded with new components that same year, suggesting attention to basic safety infrastructure. However, there have been recurring hot water issues, with reports of no hot water for extended periods in 2023, and ongoing concerns about the garage's functionality as evidenced by the recent garage door replacement in 2024 following an earlier complaint. Multiple plumbing and electrical upgrades have been completed over the years, including bathroom additions, rewiring projects, and various unit renovations, indicating ongoing efforts to maintain and improve the building's facilities. The property has also experienced some regulatory scrutiny, including a past violation for lead paint concerns in 2000 (since abated) and more recent issues in 2018 regarding unpermitted work, though these are not currently active.

Risk rating

How 690 45Th Ave'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.
