Initial analysis

The four-story multi-family residential building at 72-76 Potomac Street in Hayes Valley, owned by Timothy Dufka and Ma Carlotti, has undergone several significant renovations and improvements since its construction in 1900. The most recent permitted work, completed in January 2023, involved documenting as-built conditions on the third floor, including minor modifications to bathroom, laundry, and closet areas. The property has seen substantial electrical upgrades, including the installation of recessed lighting in 2014 ($10,000) and a comprehensive kitchen remodel in 2009 ($22,000) that included new appliances, electrical work, and plumbing. The building's systems have been maintained with regular updates, including furnace replacement in 2009 and extensive electrical work in 2004 for a solar TV system and lighting improvements.

Of particular note is the building's historical context regarding safety concerns between 2001-2005, when multiple violations were recorded related to fire proofing and building permits, though all were subsequently abated. The 2001 complaints raised serious issues about gas fumes and fire hazards from an unsealed unit and storage practices, though these appear to have been addressed promptly. Since then, the building has undergone regular routine inspections (most recently in 2016) with no open violations on record. The property has seen recent activity primarily related to parking enforcement, with multiple complaints about sidewalk parking in 2024, though these are external issues not directly affecting building safety or habitability. The building's maintenance history shows consistent oversight and resolution of issues, with all recent permits marked as complete and no active violations currently on file.

Risk rating

How 72-76 Potomac St'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

Out of 1027 buildings in this neighborhood, 534 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 floors

Building height affects maintenance complexity and is one of the size signals the model uses.

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

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 66.8%
Moderate concern 26.4%
Severe concern 6.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
