Initial analysis

The property at 1319-1321 9th Avenue in San Francisco's Inner Sunset neighborhood is a 3-unit, 2-story multi-family residential building with ground floor retail space, constructed in 1949 and currently owned by Kwong Yee Wing Wong Chui Ch. The building's maintenance record shows regular upkeep, with the most recent permit from November 2023 involving substantial bathroom remodeling on the second floor, including fixture replacements and electrical upgrades at a cost of $28,200. The property has undergone various significant improvements over the years, including a 2020 electrical system upgrade (new meter and panel installation), 2013-2010 renovations to restaurant facilities (including accessibility upgrades and refrigerator installation), and a 2003 reroofing project.

The building's history includes several important maintenance and compliance events, notably a sewer repair in 2009 and multiple inspection renewals in 1993. There have been a few building code violations, including an unpermitted construction issue in 2013 regarding a wood and plexiglass awning, which was abated by July 2013. Most recent issues primarily relate to exterior maintenance and urban conditions, as evidenced by multiple 311 calls in 2024 regarding sidewalk conditions, graffiti, and parking meter repairs. A 2019 fire violation was issued regarding kitchen hood cleaning, which was subsequently abated, and there was a temporary elevator issue in 2024 that was determined to have no merit upon investigation. The building's maintenance record suggests regular upkeep and prompt resolution of most issues, with no currently active violations or complaints directly affecting the residential units.

Risk rating

How 1319-1321 9Th 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.
