Initial analysis

The property at 75-77 Douglass Street is a two-unit, two-story multi-family residential building located in the Corona Heights neighborhood, owned by John J. and Grace E. Shanahan and constructed in 1900. The building has experienced several significant maintenance and safety issues over its history, most notably in recent years. In 2024, tenants documented persistent plumbing problems, with reports of water and sewage leaks into the backyard since 2021, and there are ongoing concerns about exposed wiring. In 2005, serious safety violations were documented, including unauthorized electrical work, inadequate heat sources, and potential lead paint hazards, though some of these issues were addressed through permits totaling $2,800. The building's occupancy status has been a point of contention, with records suggesting it was originally constructed as a single-family dwelling with two floors of occupancy plus ground floor storage, but was later occupied as a three-unit building across three floors. This illegal conversion resulted in multiple safety concerns, including unapproved wiring and plumbing installations, questionable fire safety materials, and insufficient smoke detectors, though these violations were marked as not active.

The property's maintenance history shows regular but often inadequate repairs, including siding replacement due to dry rot in 2005 and various other building improvements carried out under permits from 1998-2005. While some historical complaints have been resolved, there are concerning patterns of recurring issues, especially regarding plumbing and electrical systems. Recent 311 calls from the area have primarily concerned street-level issues such as encampments and debris, with the most recent documented case in January 2024 showing hazardous materials on the street as of this report's date. The building has undergone various repairs and improvements over the years, including kitchen renovations in 1999 and electrical panel modifications in 2005, but the persistence of certain plumbing issues suggests ongoing infrastructure challenges.

Risk rating

How 75-77 Douglass 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.
