Initial analysis

The property at 601-609 Pennsylvania Avenue in Potrero Hill is a two-story multi-family residential building constructed in 1918, currently containing four units and owned by Bruce Andrew Chapman. The building's most recent significant development attempt was an application in April 2024 to add a fifth unit and ADU in the basement, though this permit was ultimately cancelled. The building has undergone several maintenance projects over the years, including two reroofing projects (completed in 1989 and 2008 at a cost of $10,500). Electrical upgrades were performed in 2005, involving the installation of bath fans, lighting, and switches.

The building's history includes multiple housing inspection complaints in the 1990s regarding alleged illegal units in the garage area, though all these complaints were abated (resolved). Recent maintenance issues have primarily involved external factors, including tree root damage to the sidewalk (2023), a sewage backup incident (2014), and several sidewalk-related concerns. Multiple 311 calls have been logged for the property in recent years, addressing various municipal service matters such as graffiti removal, waste management, and tree maintenance. The most serious recent infrastructure concern was a sewage backup in 2014 that required intervention from PUC Sewer Operations.

Risk rating

How 601-609 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
85th percentile

Out of 726 buildings in this neighborhood, 109 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

12-Month severity forecast
No violation 54.9%
Moderate concern 32.3%
Severe concern 12.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
