Initial analysis

The 3-story, 13-unit multi-family residential building at 2334-2336 Mission Street, owned by Ng Kwan Yu, was constructed in 1912 and has undergone several significant events over the past two decades. Most notably, in late 2021, the building experienced a cluster of violations related to safety and maintenance issues, including hazardous mechanical equipment, broken windows, problematic handrails, exterior flaking paint (with potential lead hazard), and various fire safety requirements. These violations were all addressed and abated by December 10, 2021. The building has had recurring fire safety concerns, with multiple issues documented in 2018 and 2019 regarding blocked exits, fire extinguishers, and alarm systems, though all were corrected promptly. A recent fire complaint from July 2024 regarding blocked exits was also corrected.

The property has undergone some improvement work, including a circuit installation and wall heater addition in apartment #7 in 2003, and sidewalk work in 2004. Some routine maintenance issues have persisted, such as a cracked window reported in 2016 (which was resolved), and a routine complaint about common areas was filed and resolved in 2023. The building's exterior and surrounding area has experienced regular graffiti and debris issues in 2024, with several reports of sidewalk cleaning needs and graffiti removal - most of these cases were resolved through city services. The building's maintenance history suggests periods of active management response to violations and complaints, particularly in addressing safety-related issues, though some exterior maintenance matters have required multiple interventions over the years. Recent records show consistent attention to resolving safety issues as they arise, with violations being promptly addressed once cited by housing authorities.

Risk rating

How 2334-2336 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 2380 buildings in this neighborhood, 2237 are predicted to be safer.

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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Notices of Violation (past 7 years)

DBI issued Notices of Violation at this address over the last 7 years — a direct record of code enforcement activity.

12-Month severity forecast
No violation 13.7%
Moderate concern 44.8%
Severe concern 41.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
