Initial analysis

The property at 659 34th Avenue in the Outer Richmond is a two-unit, two-story multi-family residential building constructed in 1926, currently owned by Anna Zhao Lian Huang. The building has undergone several significant structural modifications over the years, including a vertical addition in 1992 costing $72,700, conversion of the first floor for a second dwelling unit and garage parking in 1991 ($31,000), and earlier safety improvements with the installation of anchor bolts in 1990. In the early 1990s, the property underwent additional changes including the removal of front and rear decks, though all these permits have since expired.

Between 2011-2012, the property was subject to two housing inspection complaints regarding unauthorized auto repair activities in an R3 zoning area, both of which were promptly abated within weeks. More recently, there has been a notable pattern of parking-related issues in the immediate vicinity, with eight documented incidents between February and May 2024, including vehicles blocking driveways and parking on sidewalks. These parking violations have generally resulted in either officers being unable to locate the offending vehicles or the issues being resolved without direct enforcement. The building's most recent complaint history includes three infrastructure-related cases in 2024 involving abandoned vehicles and parking violations, though these are more reflective of street conditions than building maintenance. A minor fire complaint regarding unlicensed auto repair was filed in October 2009 but was determined to have no merit within two days.

Risk rating

How 659 34Th 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
94th percentile

Out of 1040 buildings in this neighborhood, 62 are predicted to be safer.
