Initial analysis

The two-unit residential building at 253-255 Mississippi Street in Potrero Hill, owned by Kathleen Roberts-block Lvg, is a two-story flats and duplex structure built in 1900. The most significant and recent improvements to the property were completed in early 2024, involving comprehensive remodeling of kitchens and bathrooms in both units, including new fixtures, appliances, and electrical systems, with an estimated cost of $140,000. This work was properly permitted under building, plumbing, and electrical permits (E202402152432 and PP20240215342) and has been marked as complete. The building has a history of addressing structural concerns, notably undergoing earthquake-related foundation repairs in 2001 (though this permit expired), and a sunroom repair project in 1988 that was completed successfully. A significant building complaint was recorded in 2002 regarding unsecured construction-related safety issues, but this was promptly addressed within two days.

The property has experienced several maintenance and infrastructure updates over the years, including electrical system improvements in 2003 and plumbing work in 2020. While there have been various 311 calls recorded for the street address, these mostly relate to external issues such as street cleaning, tree maintenance, and parking concerns rather than building-specific problems. The most recent 311 call was in February 2023, regarding general street cleaning, which was resolved with no issues found. The building's maintenance record shows regular updates and improvements being made, particularly in recent years, with no outstanding building code violations or safety concerns noted in the provided data.

Risk rating

How 253-255 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, 29 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.

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

Building age

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

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

12-Month severity forecast
No violation 83.5%
Moderate concern 13.9%
Severe concern 2.6%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
