Initial analysis

The two-story multi-family residential building at 280 10th Avenue in the Inner Richmond neighborhood, owned by Jong Courtney E, was constructed in 1961 and contains 6 units. The property has experienced several notable safety and maintenance issues over its history, with the most recent fire-related concern reported in February 2023 regarding combustible materials, though this was ultimately determined to have no merit. A significant cluster of fire safety violations was documented in 2001, including problems with the central alarm system, egress obstructions, gas utility shutoff tools, fire escape ladder maintenance, and fire proofing materials - all of which were abated by June 2001. Similar fire safety concerns recurred in 2006, with violations related to the fire escape drop ladder and smoke enclosure door closers, though these were also resolved. The building has had other maintenance issues, including a broken window in 2020 (resolved within a month), and two concerning complaints from 1994 regarding water supply issues and multiple maintenance problems including a broken fire alarm box and water damage, both of which were addressed. Recent neighborhood activity has included standard urban maintenance issues such as sidewalk defects, graffiti, and parking enforcement, with records showing appropriate responses to these incidents. While the building has experienced recurring fire safety concerns over the years, it is important to note that all cited violations have been officially abated, and there are no currently active building violations on record.

Risk rating

How 280 10Th 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.
