Initial analysis

The 4-unit multi-family residential building at 280 Pennsylvania Avenue in Potrero Hill is a 2-story apartment structure built in 1912, currently owned by Vincent P & Maria Elena Ali. The property has undergone several significant infrastructure improvements over the past two decades, with the most recent major work being reroofing completed in 2020 at a cost of $17,375. Other notable upgrades include the replacement of the main water pipe in 2016, refurbishment of the rear exterior stairs in 2009, and a substantial electrical system upgrade in 2012 that included installing a new 200-amp service with individual metering for each unit. The building has been subject to regular housing inspections, with routine health and safety inspections recorded in 1999 and 2009, though neither inspection appears to have resulted in ongoing concerns.

More recently, during December 2024, there have been multiple reports of street-related issues in the vicinity of the building, including several complaints about encampments and instances of garbage and debris that were reported through the city's 311 system. While these external environment concerns have been consistently resolved by city services, they represent a notable pattern of neighborhood maintenance challenges in the immediate vicinity. The building's maintenance record shows regular attention to its infrastructure needs, with no documented building code violations or safety concerns directly related to the structure itself over the past two decades.

Risk rating

How 280 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
63th percentile

Out of 726 buildings in this neighborhood, 269 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.

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

Building age

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

12-Month severity forecast
No violation 63.7%
Moderate concern 24.3%
Severe concern 12.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
