Initial analysis

The two-story multi-family residential building at 6-12 Leroy Place, located in the Nob Hill neighborhood, was built in 1908 and contains 4 units under the ownership of the Watts Family Trust. The property has undergone several significant improvements in recent years, including the complete replacement of front windows on the first two floors in 2019 (cost: $30,000), electrical panel upgrades to Siemens panels completed in January 2024, and various exterior maintenance works such as siding replacement and deck improvements. The building has a history of addressing fire safety concerns, most notably undergoing fire damage repairs in 2004 and completing a series of fire safety compliance issues in 2009, including fire extinguisher requirements and smoke detector installations.

Recent complaints and inspections have focused on various maintenance and regulatory compliance matters, including a 2019 dispute over a potentially unauthorized vent installation, concerns about garbage placement between properties, and a routine housing inspection initiated in 2016 that is currently listed as active. The property has also seen periodic issues with basic building systems and infrastructure, evidenced by the sewer discharge incident reported in November 2024 and various sidewalk cleaning matters documented in 2022-2024. Historical records show the building experienced several housing code violations in 2000 related to safety features such as handrails, building address identification, and fire safety equipment, all of which were subsequently addressed by January 2010.

Risk rating

How 6-12 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

Out of 1125 buildings in this neighborhood, 709 are predicted to be safer.
