Initial analysis

The two-unit multi-family residential building at 551-553 17th Avenue in the Central Richmond neighborhood is a two-story structure built in 1925, currently owned by Luu Ngoc Ky & Van Chanh X. The building has undergone several significant maintenance and improvement projects over the years, with the most recent major work being the replacement of a broken sewage line from the house to the vent and p-trap in July 2020, which was completed successfully. In 2011, the property received attention to its exterior with the replacement of siding on the rear of the building (costing $7,000) and a street space permit was issued. Earlier maintenance included reroofing work in both 1993 and 2005 (costing $3,900), and various other improvements in 1998-1999 including enclosures and fire-rated wall construction.

The property has experienced some parking-related issues in recent years, with multiple 311 calls regarding parking violations, including sidewalk parking and driveway blocking, though these are not directly related to the building's condition or safety. Historical records show the building has been maintained through periodic updates and repairs, with an emphasis on basic infrastructure such as roofing and siding maintenance, as well as addressing critical systems like plumbing when necessary. While some permits from the late 1990s were marked as expired, most recent work has been properly completed and documented through the appropriate channels.

Risk rating

How 551-553 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.
