Initial analysis

The two-unit residential building at 517-519 37th Avenue in San Francisco's Outer Richmond district is a two-story flats and duplex structure built in 1981, currently owned by Lee Gordon Leong. The building's documented maintenance history includes a roofing project completed in 1997, though records show this permit has since expired. The property has experienced a notable series of parking-related incidents over the past 15 years, with the most recent cluster of complaints occurring in January 2023 involving a white Chevrolet Spark with license plate CEZ6790, though enforcement officers were unable to validate the issues upon arrival. Between 2010 and 2019, there were multiple reports of abandoned vehicles in the vicinity, including incidents involving various makes and models such as a Nissan, Subaru, and several others, though most of these vehicles were gone by the time enforcement arrived.

Historical planning records indicate the property underwent significant development in 1981 when two duplex buildings were constructed, each containing two stories and garage space, replacing a single-family dwelling. The two buildings were designed to each be approximately 1,734 square feet with two parking spaces, and this development was associated with a side yard variance request. While the building's parking-related incidents and abandoned vehicle reports suggest ongoing challenges with street parking in the immediate area, these issues appear to be more related to the neighborhood's parking dynamics rather than specific building deficiencies or management concerns. As of October 2023, there are no recorded safety violations or building code issues associated with this property that would directly impact resident safety or comfort.

Risk rating

How 517-519 37Th Ave'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.
