Initial analysis

The 2-story, 8-unit multi-family residential building at 328 Pennsylvania Avenue in Potrero Hill, owned by Kwok Chung Wong & Har Kwan, has undergone significant modifications since 2019, most notably the addition of two ADUs to increase the total units to 10. The property has seen substantial infrastructure improvements, including a $70,000 water damage repair project completed in August 2023, installation of a new fire sprinkler system in 2020 at a cost of $20,500, and a $60,000 reroofing project in 2022. The building successfully completed mandatory soft-story seismic retrofit work in 2014, demonstrating compliance with safety requirements.

Recent concerns include multiple building violations and complaints regarding unpermitted work, particularly in 2023, related to unauthorized demolition work in Unit B and a history of issues regarding a roof deck construction in 2020. These violations have since been abated, with the most recent being resolved in March 2024. The property has experienced some maintenance issues, evidenced by recent sewer discharge incidents in July 2024, though these were addressed by municipal services. Infrastructure upgrades have included a 400-amp electrical service upgrade in 2020 and comprehensive fire safety improvements, including a new fire alarm system and sprinkler system installation to meet current safety codes.

Risk rating

How 328 Pennsylvania 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
