Initial analysis

The property at 285-287 10th Avenue in San Francisco's Inner Richmond district is a two-story, multi-family residential building constructed in 1914, currently owned by Helen Leong Survivor's Trust and containing three units. The building has experienced significant maintenance and safety issues in recent years, with the most pressing concerns being a pattern of garbage and debris accumulation around the property, with ten separate cleanup calls recorded between September 2024 and January 2025, including instances of furniture and bagged garbage that required intervention from Recology and Public Works. There have also been recent safety concerns regarding the building's clay tile decorative mansard, with complaints filed in September 2023 about falling and loose tiles posing a potential hazard to pedestrians. The building's history includes a serious incident in 2004 when it was temporarily abandoned and boarded up, during which time issues of trash accumulation and unauthorized occupancy were reported, though these were resolved within a few weeks. Earlier records show substantial rehabilitation work following a fire incident in 2004, including window replacements, bathroom and kitchen remodels, and electrical system upgrades totaling over $100,000 in improvements. While the property underwent exterior improvements in 2011 with the installation of vinyl siding on the rear of the building, recent maintenance concerns suggest ongoing challenges with property upkeep. A historical violation regarding an unauthorized dwelling unit in the rear garage area was filed in December 2004, though this appears to have been abated shortly thereafter.

Risk rating

How 285-287 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.
