Initial analysis

The property at 1921 Ocean Avenue is a two-unit, two-story multi-family residential building with retail space below, built in 1924 and currently owned by the Kwan/choy Family Trust. The building has experienced several significant maintenance and safety issues over its history, with the most serious cluster of problems occurring in September 2009 when multiple violations were documented, including rodent infestation, mold/mildew issues, fire safety concerns (fire extinguisher maintenance, smoke detector repairs), security deficiencies (entry door viewers), and general sanitation problems. These violations were all addressed and abated by December 2009. More recent concerns include a 2023 electrical pre-inspection regarding service cleanup and a 2023 operating without a permit fire complaint that was promptly corrected.

The building's fire safety record shows multiple historical violations between 2006 and 2020, including blocked exits and extinguisher issues, all of which were resolved. A minor cooking fire was recorded, though it was contained and resulted in no injuries. The property underwent significant planning processes, including subdivision variance approvals, though these records show "None fNone" under developer information. Recent activity (2024) has primarily involved street-level issues such as garbage, debris, and parking enforcement matters, which are being handled through the city's public service channels. The building's plumbing infrastructure includes a grease trap that was inspected in 2013, and there was one complaint in 2002 regarding sidewalk work that was quickly resolved.

Risk rating

How 1921 Ocean 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
