Initial analysis

The three-unit, two-story multi-family residential building at 510 5th Avenue in San Francisco's Inner Richmond district, owned by the George Wong Trust, has been in service since 1971 and has undergone regular maintenance of its roofing systems, with documented re-roofing projects completed in both 1992 and 2015 at costs of approximately $15,900. The building has maintained compliance with housing safety standards through several routine safety inspections conducted between 1999 and 2016, with no active violations recorded from these inspections. The property's most significant recent issue has been a series of persistent parking management challenges, with multiple reports of driveway blocking incidents between June 2024 and January 2025, during which violations resulted in citations being issued on several occasions, though some cases were closed due to officers being unable to locate the offending vehicle.

The building's maintenance history demonstrates proper attention to structural upkeep, with both historical and recent roofing projects showing investment in building integrity. The property underwent systematic oversight through regular housing inspections, with no noted safety concerns or violations following these evaluations. Recent activity has predominantly involved external parking enforcement matters rather than building-specific issues, suggesting the property itself remains in good standing from a building code perspective. The most recent inspection records are from 2016, with no documented inspections appearing in the past seven years, though this does not necessarily indicate any compliance issues given the non-active status of past inspections. The building continues to operate as a three-unit apartment complex consistent with its original configuration.

Risk rating

How 510 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.

Neighborhood percentile
