Initial analysis

The three-story multi-family residential building at 679-681 9th Avenue in the Inner Richmond, owned by Chan Kin Wai, has a documented history dating back to its 1916 construction. Most recently, in June 2024, the building underwent significant roof work costing $15,000, which included removing the existing built-up roof, replacing all roof flashing, and installing new materials including fiberglass base sheet and modified bitumen components, demonstrating ongoing maintenance of the property. A substantial renovation occurred in 2007 when interior stairs were added from the second floor to the ground floor, along with the construction of two new bathrooms, with appropriate plumbing and electrical work completed under permits totaling $25,000. The building has undergone multiple roofing projects over the decades, with records showing work in 1993 and 1997, though these permits expired.

The building's maintenance history includes addressing several building violations in May 2000, which were promptly abated by June 2000 and involved repairs to damaged walls and sinks, indicating responsive management to maintenance issues. A more recent complaint from August 2010 raised concerns about a possible illegal unit with water damage issues in a ground floor unit, though this complaint was marked as not active on the same day it was filed. While there was a general cleaning complaint regarding loose garbage in August 2022, this was a street-related issue handled by the Department of Public Works and not directly related to the building's condition or management. The property's record shows a pattern of routine maintenance and prompt response to violations, with no active violations or complaints on record as of October 2023.

Risk rating

How 679-681 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.

Neighborhood percentile
