Initial analysis

The historic three-unit building at 423-425 33rd Avenue in San Francisco's Outer Richmond neighborhood, owned by Andre Winiarski, has undergone significant modifications since its 1925 construction. Originally a two-unit structure, the property faced enforcement actions in 2008 for unauthorized third-unit conversion, which was subsequently legalized in 2014 with required fire safety improvements including a new sprinkler system. The building has experienced recurring maintenance and safety issues, with the most recent tenant complaints in 2023 reporting no heat, mold, and structural problems in the third-floor unit. Prior concerns include water leaks and mold in 2017, and heating system issues in 2008 that were addressed through various permits and inspections.

Recent work on the property demonstrates both ongoing maintenance and some concerning patterns: 2024 records show new HVAC installation and sprinkler monitoring work, while previous improvements include electrical upgrades, fire safety systems, and plumbing renovations. The building has seen two tenant buyouts in recent months (December 2023 and March 2024) totaling over $55,000, though the impact of these buyouts on building conditions is unclear. The property's maintenance history includes several general cleaning issues addressed by city services, primarily involving garbage and debris management in the surrounding areas. While many building systems have been updated through various permits, the recurring nature of tenant complaints suggests ongoing maintenance challenges.

Risk rating

How 423-425 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.
