Initial analysis

The three-story multi-family residential building at 3685-3687 Mission Street in Bernal Heights, owned by Joseph K Choi, was constructed in 1981 and contains two units. The property has undergone several significant improvements and faced some maintenance challenges over the years. In 2008-2009, major modifications were made including a $20,000 garage door and entrance relocation project, followed by the installation of a new reroof costing $2,800. Between 2012 and 2018, the building experienced several overlooked maintenance issues, including a 2012 complaint about cockroaches, inadequate heat, and construction concerns, though these were resolved by April 2012. In October 2018, multiple fire safety violations were recorded regarding egress obstructions and sanitation issues, with these violations notably being abated by November 20, 2018.

More recently, the property has faced some ongoing external maintenance challenges, particularly in 2024, with multiple 311 calls regarding garbage and debris and pavement defects near the property. The area has also seen utility work, as evidenced by the August 2024 reports about temporary PG&E gas main restoration work in the vicinity. A historical fire complaint from July 2016 regarding combustible materials was investigated but found to have no merit. The building's maintenance history shows a pattern of addressing major structural and safety components, though with some periods of reactive response to resident-reported issues. The property has had proper permit approvals for various modifications, including a significant garage door project and subsequent revisions to utilities placement.

Risk rating

How 3685-3687 Mission St'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

Out of 1276 buildings in this neighborhood, 1059 are predicted to be safer.

Model explanation

What's driving this score

The three data points that most influenced this building's risk rating — ranked by the weight the model placed on each one.

Building size

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

Neighborhood location

Precise location is a proxy for neighborhood-level risk — some SF blocks have systematically higher DBI activity.

NOV rate, owner's portfolio

Per-building NOV rate across everything this owner manages — high rates signal pattern neglect.

12-Month severity forecast
No violation 65.6%
Moderate concern 11.0%
Severe concern 23.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
