Initial analysis

The property at 2115 23rd Street in Potrero Hill is a two-story, three-unit multi-family residential building constructed in 1907, currently owned by the Jeffrey W Moss Living Trust. The building has undergone several significant structural improvements over the years, with the most recent major work occurring in 2022 when a retaining wall at the west property line was repaired at a cost of $50,000 following a notice of violation issued in March 2022 regarding its failing condition. This wall, approximately 35 feet long and 4 to 6 feet high, was reported to be tilting and potentially unsafe. The building has a history of structural maintenance dating back to the late 1980s, including foundation work, concrete wall replacement, and various repairs documented through multiple permits. Between 1988 and 1990, several repairs were completed, including reroofing and replacement of damaged sheetrock and exterior siding.

In 2022, there was also a complaint filed regarding a derelict structure in the neighbor's garden, reportedly infested with rodents and raccoons, though this complaint was abated within two days. The property has been the subject of numerous 311 calls in recent years, primarily related to parking issues, including abandoned vehicles and blocked driveways, with the most recent incidents occurring in 2024. There were also two street cleaning complaints in early 2022, which were resolved. The building's documented history shows regular maintenance and repair work, with particular attention paid to structural elements like walls, roof, and foundation, though some permits from the late 1980s and early 1990s show as expired rather than completed.

Risk rating

How 2115 23Rd 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, 668 are predicted to be safer.
