Initial analysis

The property at 957 De Haro Street in Potrero Hill is a two-story, three-unit multi-family residential building constructed in 1926, currently owned by Sandra Lee Wieland Sprt Prp. The building underwent significant proposed development activity in 2022, with plans filed to construct a new four-story, two-unit residential building with basement level on the southern half of the lot, estimated at $2 million. Prior to this, an alteration permit was issued to remove non-permitted improvements from the south elevation of the existing two-unit building and upgrade it to meet current codes. In February 2022, an administrative permit was successfully completed to document the legal use of the property as a three-story, two-family dwelling.

The planning records indicate a proposed subdivision of the existing 50-foot lot into two 25-foot lots, retaining the existing structure on the northern portion while constructing new two-unit buildings on both the existing and proposed lots. There has been substantial recent activity at the property, with multiple 311 calls recorded in 2024, primarily related to external issues such as transit shelter damage, sidewalk defects from tree roots, noise complaints, and general maintenance matters. Notably, the seven transit shelter damage reports between July and September 2024 and the sidewalk defect issue remain open, suggesting ongoing concerns in these areas.

Risk rating

How 957-963 De Haro 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, 334 are predicted to be safer.
