Initial analysis

The two-unit residential building at 282-284 27th Avenue, located in the Lake-Presidio neighborhood, is a two-story flats and duplex structure built in 1924 and currently owned by David Tam. The building has undergone minimal official modifications in the past two decades, with the most significant being a window replacement project in 2001 that involved installing seven new vinyl windows on the front facade, though this permit has since expired. The property has experienced several parking-related issues in recent years, with multiple reports of driveway blocking between 2018 and 2024, though most of these cases were either not validated by responding officers or were closed as the vehicles were gone upon arrival.

The building's safety record shows three fire-related incidents, though none involved civilian injuries; these include two invalid assists and one smoke detector activation due to malfunction. More recent concerns include an open tree-related maintenance issue from February 2023 regarding sidewalk damage from tree roots. In March 2020, there were three separate complaints related to private home showings, likely connected to property marketing activities, all of which were closed with comments regarding permitted real estate practices. The property has experienced a series of abandoned vehicle reports between 2016 and 2024, primarily involving vehicles that were not present when enforcement arrived. While the building's overall record shows no major safety incidents or significant building modifications, the concentration of parking enforcement issues and one instance of tree-related property damage may be of note to prospective tenants.

Risk rating

How 282-284 27Th 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.
