Initial analysis

The property at 850-852 33rd Avenue is a two-story, multi-family residential building located in San Francisco's Outer Richmond neighborhood, constructed in 1924 and containing three units. The Chow Family Trust currently owns the building, which has undergone significant renovations and maintenance work over the past decade. Between 2015-2022, major improvements included window replacements (2022), comprehensive renovations of kitchens and bathrooms in both units 850 and 852 (2015-2016), complete electrical rewiring (2015-2016), furnace replacements (2016), and a new roof installation (2015). The building has a documented history of addressing building code violations, particularly from a cluster of citations in 2002 related to security, stair repairs, fire safety, and utility shutoff requirements, all of which were promptly abated by October 2002.

Recent maintenance work has focused on window upgrades, with 2022 improvements featuring energy-efficient Marvin windows with a <.30 U-factor. The building's systems have received modern updates, including electrical rewiring to accommodate 41 or more outlets, new plumbing installations, and comprehensive kitchen and bathroom renovations across multiple units. The only recorded fire-related incident was a malfunctioning carbon monoxide detector, which resulted in no injuries. The property's maintenance record shows regular upkeep, with historical permits indicating earlier work such as roofing repairs in 1991 and code compliance work in 1984. The building's location has generated minimal neighborhood complaints, primarily related to parking issues in front of the building, with these being typical urban enforcement matters rather than building-specific concerns.

Risk rating

How 850-852 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.

Neighborhood percentile

29th percentile

Out of 1040 buildings in this neighborhood, 738 are predicted to be safer.
