Initial analysis

The three-unit residential building at 475-479 Mississippi Street in Potrero Hill is a three-story flats and duplex structure dating back to 1900, currently owned by Frank Ybarra Palomarez. The building's documented history includes a kitchen renovation project from 1990 involving cabinet and countertop replacements, though this permit has since expired. A significant infrastructure improvement was completed in 2003 with the installation of a 100-amp electrical upgrade on the ground floor as part of a Rule 20a underground conversion project, which represents progress towards modern electrical standards. The only recorded non-structural incident was a minor case of graffiti on a sign in 2016, which was handled by the Department of Public Transportation Sign Shop and was not considered offensive. This incident was properly addressed and closed, with no ongoing safety or maintenance issues reported through the 311 system. The building's permit and incident history suggests regular maintenance with no major safety concerns or violations on record in recent years.

Risk rating

How 475-479 Mississippi 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 726 buildings in this neighborhood, 341 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.

Building age

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

Property class: multi-family flat

2–4 unit flats (class F) are a common SF building type with their own maintenance and complaint patterns.

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

12-Month severity forecast
No violation 52.2%
Moderate concern 35.6%
Severe concern 12.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
