Initial analysis

The two-unit multi-family residential building at 1400 34th Avenue in the Central Sunset neighborhood, owned by Kwan Jun and Git Jun Young, has experienced several maintenance and cleanliness issues over recent years. Since 2021, there have been multiple incidents requiring street and sidewalk cleaning, including three instances of abandoned garbage and debris (most recently in July 2024), as well as the removal of electronic waste and furniture in October and September 2024, respectively. The property has also been impacted by several sanitation issues, including a case of human or animal waste in August 2023 that required PUC Sewer Operations intervention.

More recent concerns include an open graffiti case from January 2025 and a rent board inquiry from the same month, both of which remain unresolved as of now. The building's exterior and surrounding area have faced various challenges, including a bent stop sign that was reported and subsequently resolved in August 2024. Historical records show the property has been subject to similar issues in previous years, with documented cases of graffiti (both offensive and non-offensive) in 2022, and general cleaning needs in 2021-2022, all of which were eventually resolved. While the majority of these incidents have been addressed through city services, the recurrence of cleanliness and maintenance issues suggests an ongoing challenge in maintaining the immediate environment.

Risk rating

How 1400 34Th 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.
