Initial analysis

The 25-unit multi-family residential building at 446-450 5th Ave in the Inner Richmond neighborhood, owned by Patrick W H Wong and constructed in 1991, has undergone several significant upgrades and faced various maintenance challenges over the years. Most notably, in late 2024, comprehensive fire alarm system upgrades were completed at a cost of approximately $107,000 to comply with current safety requirements, following multiple earlier projects related to fire safety between 2018-2020. The building has experienced several concerning maintenance issues, particularly in 2020, with active complaints regarding cracked walls, broken window frames, air infiltration, and multiple appliance and heating system malfunctions in Unit #18. There have been recurring fire safety inspections, with a current violation open as of October 2023 regarding sleeping area requirements.

The property has a documented history of fire safety concerns, including multiple fire alarm activations, cooking fires, and system malfunctions, though fortunately without resulting injuries. Significant improvements have been made to the building's systems, including a $48,000 reroofing project in 2017 and various unit-specific renovations such as a $38,000 kitchen and bathroom remodel in Unit #18 in 2020. The building's maintenance record shows regular attention to fire safety requirements, with several instances of conditions being corrected promptly following violations. Recent maintenance history (2023-2024) shows ongoing attention to building upkeep through fire system upgrades and routine maintenance, though some historical issues related to heating, electrical systems, and structural elements have been documented through complaints and violations dating back to 2009-2010.

Risk rating

How 446-450 5Th 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.
