Initial analysis

The 8-unit, 2-story multi-family residential building at 324 Pennsylvania Ave in Potrero Hill, owned by B4n LLC and constructed in 1960, has undergone several significant maintenance and improvement projects over the past few years. Most notably, the building completed a mandatory soft-story retrofit in 2017 at a cost of $70,000, achieving full compliance with seismic safety requirements. Recent maintenance includes dry rot wood repair around five windows in Apartment #4 completed in December 2023, and previous improvements such as a kitchen cabinet replacement in Unit #2 in 2021, which was accompanied by proper plumbing updates. The building has a history of maintenance issues requiring attention, including a roof replacement in 2007 and stair repairs in 2001.

Several complaints have been filed regarding construction practices and safety concerns, with the most serious incidents occurring in late 2019 when unsafe generator use in the carport triggered carbon monoxide exposure in one unit, along with multiple instances of blocked building exits. There have also been complaints about unauthorized construction work and permit violations in 2016-2020, though many of these complaints are now marked as "Not Active" or "Abated." A recent complaint filed in May 2024 concerns an unauthorized fence construction affecting parking areas, though this complaint is currently not active. The building's maintenance record shows regular upkeep, though there have been periodic issues with construction management protocols and permit compliance that have required tenant intervention through complaints. Outside the building itself, there have been routine municipal service requests for sidewalk cleaning, graffiti removal, and other urban maintenance issues in the surrounding area, typical for the neighborhood.

Risk rating

How 324 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.
