Initial analysis

The property at 1319-1321 17th Ave in San Francisco's Inner Sunset neighborhood is a two-story, two-unit multi-family residential building constructed in 1924 and currently owned by Kuang Liang Huang and Liang Cai. The building's maintenance history reveals several significant concerns over the past two decades, with the most serious issues occurring in 2002-2003 when multiple violations were documented regarding unsafe back stairs, deteriorated handrails, and mold growth, including an investigation of a possible unpermitted third unit on the ground floor. These violations, which raised safety and habitability concerns, were ultimately abated by March 2003 following a sequence of Notices of Violation (NOVs) and corrective actions including staircase repairs costing $800. A subsequent complaint in 2011 again reported similar issues with building disrepair, broken windows, and concerns about the back stairs.

The building has undergone some maintenance work over the years, including a reroofing project in 2003 costing $5,200 and various bathroom fixture replacements documented in 1986, though the latter permit is now expired. More recent history shows relatively minor issues, with only two 311 calls in the past several years - one regarding a blocked driveway in 2023 and another about graffiti on AT&T property in 2021, both of which were resolved. While the property has experienced recurring maintenance challenges in the past, particularly during the early 2000s, there have been no documented building code violations or major complaints in recent years, suggesting improved maintenance practices in the past decade.

Risk rating

How 1319-1321 17Th 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.
