Initial analysis

The three-story, six-unit multi-family residential building at 7-19 Leroy Place in Nob Hill, owned by the John E Wai 1981 Living Trust, was constructed in 1908 and has undergone several significant renovations and faced various challenges over its lifetime. The most pressing current issue, as of December 2024, involves active complaints regarding severe wastewater leaks affecting multiple basement areas, with documented instances of sewage backup into upper floors and drain fly infestations, along with recent plumbing and ceiling leaks. The building's maintenance history shows substantial remodeling work in 2011, including significant interior reconfigurations and bathroom additions, along with more recent infrastructure updates such as sewer main p-trap replacement in December 2024 and historical furnace replacement in 2012.

The property has experienced multiple compliance issues over the years, including a notable Soft Story Retrofit Program violation in 2017 that was only abated in early 2024. There have been recurring concerns about unauthorized construction activities, temporary repairs becoming permanent solutions, and various maintenance violations related to plumbing, electrical systems, and fire safety equipment. The building's history includes several fire alarm system activations, though none resulted in civilian injuries, and a 2015 fire-related inspection that was resolved with conditions corrected. A recent planning violation was recorded regarding unauthorized rooming/boarding house operations, indicating potential non-compliance with housing regulations. The most recent building complaints filed in 2024 suggest ongoing maintenance and infrastructure challenges requiring attention.

Risk rating

How 7-19 Leroy Pl'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
