Initial analysis

The duplex property at 551-553 33rd Avenue in the Outer Richmond district is a two-story multi-family residential building constructed in 1979, currently owned by William M. and Beatrice T. Yuen. The building has undergone several significant improvements over the past decades, with the most recent major work being a furnace replacement in August 2018. In 2010, substantial renovations were completed in unit 553's penthouse, including a bathroom remodel and bar area upgrades, with associated electrical and plumbing work totaling approximately $13,000. Earlier improvements from 2009-2010 involved various maintenance and upgrades, including vinyl siding installation, dry rot repair, re-roofing, and comprehensive kitchen and bathroom remodeling in both units, totaling over $40,000 in improvements. The property has maintained relatively good structural conditions, as indicated by the nature of the permits issued.

Recent activity regarding the property has primarily involved parking-related issues, with multiple complaints recorded between 2021-2024 regarding vehicles blocking driveways and parking on sidewalks. There have also been occasional issues with street cleanliness, including reports of overflowing garbage cans and loose garbage, which were promptly addressed by city services. A sidewalk defect was reported and resolved in April 2017, though this appears to be a separate infrastructure issue rather than a building concern. All building permits and improvements have been properly completed, suggesting regular maintenance and attention to building standards by the current owners.

Risk rating

How 551-553 33Rd 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.
