Initial analysis

The three-story, two-unit multi-family residential building at 2345 Mariposa Street in Potrero Hill, owned by Ted K & Sandra Surber, was constructed in 1991 following the demolition of a gas station on the site in 1987. The building's construction and modification history includes several permit renewals and revisions, particularly concerning a fire sprinkler system, with the original construction permit issued in 1988 for $320,000. While the building itself appears to be structurally sound, the property has experienced periodic maintenance issues in the surrounding area, with seven 311 calls recorded between 2019 and 2022, primarily relating to hazardous materials like broken glass on the street and sidewalk, tree maintenance concerns, and general cleaning needs. Notably, there were two tenant buyouts recorded at the adjacent 2325 Mariposa Street address, one in November 2018 for $30,000 and another in September 2020 for $80,000, though these are not directly related to the subject property. The most recent documented building permits date back to 1992, suggesting no major structural modifications have been made in recent decades, which is consistent with the general trend of minimal changes to comparable buildings of this age.

Risk rating

How 2345 Mariposa 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
86th percentile

Out of 726 buildings in this neighborhood, 102 are predicted to be safer.

Model explanation

What's driving this score

Neighborhood (ZIP code)

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

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

Moderate concern 13.4%
Severe concern 3.5%
