Initial analysis

The Rose Mary Cook Trust 2015 owns this two-unit, two-story multi-family residential building located at 231-235 Missouri Street in Potrero Hill, which was constructed in 1907. The property has experienced several significant maintenance issues over the years, with the most recent major work being a $24,850 reroofing project completed in 2022. A notable incident occurred in 2010 when the building suffered fire damage to the front porch and stairs, which required emergency repairs that were completed quickly. The property has a history of staircase-related problems, with multiple permits from 2001 showing attempts to repair front and rear stairs, treads, and handrails, though some of these permits expired before completion. During 2001-2002, the building faced multiple housing code violations that were ultimately addressed, including issues with windows, stairs, plumbing, water damage, ceiling damage, and weatherproofing. A serious complaint from 1995 documented numerous structural and systems problems including cracking walls, support beam fractures, water damage, electrical issues, and ventilation concerns, though these appear to have been resolved. The building's recent history shows no major building code violations since 2010, though there has been a notable pattern of parking enforcement calls for driveway blocking issues in 2024, with multiple cases being reported and some resulting in citations.

The property has undergone several inspections and permit processes over the years, with most issues being addressed through proper channels, though there have been instances of expired permits and some cases that required additional permitting to complete previous work. The 2010 fire incident and subsequent repairs were handled according to code requirements, and the most recent building improvements (including the reroofing) indicate ongoing maintenance of the property. While the building has a documented history of maintenance challenges, particularly in the early 2000s, the most recent records suggest improved upkeep, with no major building violations since the 2010 fire incident. The property has retained its original use as a multi-family residential building throughout its history.

Risk rating

How 231-235 Missouri 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
88th percentile

Out of 726 buildings in this neighborhood, 87 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.

Construction spend, owner's portfolio

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

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.

12-Month severity forecast
No violation 76.7%
Moderate concern 16.9%
Severe concern 6.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
