Initial analysis

The three-unit, two-story multi-family residential building at 15 Corwin Street, built in 1958 and currently owned by Rosemary Court Properties LLC, has undergone several significant infrastructure upgrades over the past three decades. The most recent and comprehensive work, completed in March 2024, involved a complete electrical system modernization across all units, including the replacement of fuse panels with circuit breaker panels in Units B and C, as well as upgrades to the house panel. Prior to this, the building underwent a voluntary seismic upgrade to its garage opening in 1996, and a furnace replacement was completed in 2007.

The property has experienced some maintenance and safety issues over the years, with records showing two sewage backup incidents in December 2021 that required intervention from PUC Sewer Operations, and a collapsed sidewalk situation in May 2022 related to a sunken utility vault cover. A fire safety complaint regarding exit maintenance was filed and closed in July 2018 with no jurisdiction found. The building has been subject to routine housing inspections in 2003 and 2011, with no active violations noted. Various 311 calls in recent years have primarily concerned street-related issues, including illegal parking, garbage and debris, and curb defects, though most have been resolved promptly.

Risk rating

How 15 Corwin 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
