Initial analysis

The property at 882 47th Ave in the Outer Richmond is a 2-unit, 2-story multi-family residential building constructed in 1957, currently owned by Li Yolanda Yan Ting. The building has experienced recurring maintenance issues, particularly in the past two years. Most notably, there has been an ongoing concern with floor coverings, with two active violations filed in August 2023 (complaint #202312200) and September 2024 (complaint #202428771) related to sagging and damaged kitchen flooring. Additionally, the 2024 complaint mentions concerns about the garage unit's non-functioning fan and broken fiberglass paneling for the exterior secondary egress.

The building has faced several significant infrastructure challenges, particularly regarding plumbing and sewer systems. There have been multiple reports of sewage-related issues, with incidents recorded in November 2023 and January 2024, and a sewage backup was also noted in a 311 call in October 2024. Recent health concerns include documented instances of rodent infestation (September 2024) and mold/mildew (September 2024), both of which were accepted by the Department of Public Health Environmental Health Services. These present and past issues suggest ongoing maintenance challenges, though some earlier violations from October 2022 regarding floor coverings and a broken kitchen sink were marked as resolved in April 2023. The building, which underwent some electrical and plumbing corrective work in 1984, has seen limited major structural changes over the decades, with most issues revolving around maintenance concerns in recent years.

Risk rating

How 882 47Th 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.

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.
