Initial analysis

The 4-unit, 2-story multi-family residential building at 1222 21st Avenue in the Central Sunset neighborhood was constructed in 1964 and is currently owned by the Leong/iwan Family Trust 2003. The building's inspection history reveals several notable events, with the most significant being a fire safety violation in August 2001 regarding combustible storage in the garage area, which was initially cited by Housing Inspection Services but required multiple notifications before being resolved by September 2001. A plumbing permit violation was also recorded in September 2009, which similarly took multiple notifications to resolve by January 2010. More recently, in March 2018, a routine housing inspection was conducted, though no violations are currently on record from this inspection. The property has generated minimal 311 calls, with only two unrelated incidents: a report of an abandoned vehicle in 2016 that was resolved when the vehicle was no longer present, and a utility excavation issue in 2009 that was addressed appropriately through city channels. While the building has experienced some compliance issues in the past, particularly in the early 2000s, there have been no reported violations or serious safety concerns in the more recent years, suggesting improved maintenance and compliance practices, though recent inspection findings are not available in the provided data.

Risk rating

How 1222 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.
