Initial analysis

The property at 61-63 Leo Street is a single-story, two-unit multi-family residential building located in Mission Terrace, owned by Kenneth Yuen and Bonnie Nhan. Built in 1964, this flats and duplex-style building has undergone several documented improvements over the years, including a bathroom remodel in 2003 (costing $6,000) involving drywall removal, plumbing fixture installation, and potential framing repairs. In 2002, permits were issued for replacing the siding, two glass sliding doors, and two windows on the rear of the building, though these permits ultimately expired without completion. A roofing project was initiated in 1997 but the permit has since expired.

Recent maintenance and environmental concerns have been documented through multiple 311 calls, with the most recent occurring in August 2024, reporting instances of human waste or urine that required street and sidewalk cleaning by Public Works Street and Environmental Services. A notable pattern emerges from the 311 call records, with a total of ten such incidents reported between April 2020 and August 2024, primarily concerning human or animal waste on public paths around the property, with most cases being promptly resolved through official cleaning services. While these external sanitation issues have been consistently addressed through municipal services, they represent a significant environmental concern in the immediate vicinity of the property.

Risk rating

How 61-63 Leo 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.
