Initial analysis

The Zhong Family Trust owns this 3-unit, 2-story multi-family residential building located at 1214-1216 21st Ave in San Francisco's Central Sunset neighborhood. Built in 1926, this flats and duplex structure has undergone several significant events over its history. Most notably, the building was approved for a variance to legalize a third dwelling unit at the rear of the ground floor without providing the additional required off-street parking space. This building has experienced recurring fire safety concerns, particularly in 2001 and 2018, with multiple violations related to combustible storage, fire extinguisher maintenance, smoke enclosure doors, and garbage receptacle placement, though all of these violations were ultimately abated. The building underwent reroofing work in 2016, costing $5,000.

More recently, there has been a pattern of parking-related issues around the property, with multiple 311 calls regarding sidewalk parking and blocked driveways between 2019 and 2025, most of which resulted in citations being issued. There was one service request regarding garbage cans being left out continuously in 2011, and a routine housing inspection in 2009 that addressed various fire safety and security requirements. The property's maintenance record shows generally responsive management to compliance issues, with most violations being addressed within reasonable timeframes.

Risk rating

How 1214-1216 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
