Initial analysis

The 8-unit, 2-story apartment building at 630 33rd Avenue in the Outer Richmond, owned by Walter Fong Bypass Trust, was constructed in 1926 and has undergone several significant improvements over its lifetime. Most notably, in 2024, the building received substantial upgrades to its fire safety systems, including the installation of a new fire alarm panel with compatible devices and low-frequency sounders in sleeping areas, at a cost of $18,700. The building has experienced recurring maintenance issues in recent years, with multiple complaints in 2024 regarding ceiling damage, plumbing problems, and window issues. A voluntary seismic upgrade was completed in 2013, addressing soft-story concerns at a cost of $45,000. The property has a history of various maintenance challenges, including past violations in 2002 related to fire safety, security, and alarm systems, all of which were abated by July 2002. Earlier complaints from 2011 and 2005 indicated problems with leaks and ceiling damage, while 1996 issues involved window locks and mold. Recent service requests from 2023-2022 primarily relate to parking and noise concerns. The building's maintenance history shows a pattern of periodic repairs and system upgrades, with the most recent fire safety improvements representing a significant investment in building safety infrastructure.

Risk rating

How 630 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.
