Initial analysis

The two-unit residential building at 2375 Mariposa Street in Potrero Hill, completed in 1991, has experienced several notable issues affecting resident comfort and safety over the years. Most recently, in 2021, the building had a broken house trap issue that required attention from the Plumbing Inspection Division, though this matter is now listed as not active. Earlier problems included two separate incidents of inadequate heating in March 2011, which were resolved within a month. The building has also faced safety compliance challenges, with a 2013 violation related to egress obstruction that was addressed in October of that year.

The building's fire safety record shows multiple smoke detector activations, though none resulted in civilian injuries, as well as nine documented fire department responses for various incidents, including a contained cooking fire and a water evacuation situation. Historical records show proper installation of a fire sprinkler system in 1990 and completion of the building's construction in 1988, though some earlier permits from the mid-1980s were either expired or cancelled. Recent municipal service calls (from October to December 2024) have primarily concerned external issues such as street lighting maintenance, tree damage, and public cleaning services, rather than building-specific problems. The property maintains its original two-story, multi-family residential structure as permitted, with ownership registered to Ted K. & Sandra J. Surber Rev.

Risk rating

How 2375 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
