Initial analysis

The property at 1395-1397 21st Avenue in the Central Sunset neighborhood is a two-unit, two-story multi-family residential building constructed in 1938, currently owned by the Wan Family Trust. The building has undergone several significant improvements over its lifetime, with the most substantial renovation occurring in 2007 when a comprehensive project valued at $20,000 was completed to add a laundry room, playroom, and full bathroom on the first floor, along with the electrical and plumbing work necessary for these modifications and the relocation of the water heater and furnace. Earlier maintenance was performed in 2000 to address dry rot issues in the front wall and to replace a garage window.

The building has experienced a notable cluster of issues in recent months, with eight reported incidents of garbage and debris on or near the property between August and December 2024, including instances of electronics, glass, liquid spills, and human waste. Three of these incidents involved defaced parking signs, which are currently open cases as of October 2024. Additionally, there were five false fire alarm incidents recorded, though none resulted in civilian injuries. A street space permit was issued in 2014, and another street space and sidewalk permit was obtained in 2007, suggesting occasional use of public space for building-related activities. While the building's major systems and living spaces have been upgraded, the property currently faces significant challenges with street cleanliness and maintenance of public spaces, as evidenced by the frequency and variety of recent 311 calls.

Risk rating

How 1395-1397 21St 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
62th percentile

Out of 814 buildings in this neighborhood, 309 are predicted to be safer.
