Initial analysis

The three-story, six-unit multi-family residential building at 10 Ada Court in Downtown, owned by O'farrell Properties LLC, has a mixed history of maintenance and safety issues since its construction in 1914. The most recent notable incident was a fire complaint in 2023 regarding blocked exits, which was closed with no merit on June 16, 2023. This followed a 2021 fire-related concern about alarm systems, which was resolved by June 16, 2021 through corrected conditions. The building's maintenance record shows a water heater replacement in 2016, when a leaking 75-gallon unit was replaced along with the installation of a new expansion tank. An expired building permit from 1997 indicates reroofing work was performed at that time.

Recent street-level activity around the building has been significant, particularly in late 2024, with multiple 311 calls regarding garbage and debris on the street and sidewalk. There were eight such incidents between November 12 and December 17, 2024, including reports of human waste, liquid spills, and various types of debris, all of which were resolved by city services. Two reports of sidewalk parking violations were filed in November 2024, though enforcement officers were unable to locate the offending vehicles. A historical building complaint from November 29, 2012, regarding lack of heat in the building was filed but not actively abated.

Risk rating

How 10 Ada Ct'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.

Neighborhood percentile

Model explanation

What's driving this score

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

12-Month severity forecast
No violation 37.5%
Moderate concern 20.8%
Severe concern 41.7%
