Initial analysis

The two-unit multi-family residential building at 2225-2227 33rd Avenue in the Parkside neighborhood, owned by Ren Hui Zhong & Bi Zhu Li, has undergone several significant alterations since its construction in 1937. The most substantial modification was the legalization of an in-law unit on the first floor in 2014, which included work on bedrooms and bathrooms, completed at a cost of approximately $119,094. This project was followed by various compliance-related permits in 2017 for plumbing and electrical work, and most recently, a May 2024 permit to address front setback landscaping and permeability requirements that had been the subject of a building violation issued in April 2024.

The building's recent history shows some concerning patterns, including multiple fire alarm incidents between 2017-2021, though most were determined to have no merit or were promptly corrected. There are also several open infrastructure issues being reported in January 2025, including water leaks and deck stairs handrail concerns. The property has experienced some compliance challenges, as evidenced by the 2024 building violation regarding front setback work. Notably, the surrounding neighborhood has seen tenant buyouts in 2018-2020 at nearby addresses, with amounts ranging from $20,000 to $50,040 for various units. The property has no active violations or unresolved complaints as of the current date, and the owners appear to be addressing required compliance matters, as demonstrated by the recent completion of the front setback restoration work.

Risk rating

How 2225-2227 33Rd 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.
