Initial analysis

The two-unit residential building at 3330 25th Street in San Francisco's Inner Mission, owned by Deng Glen Guoxiang, is a two-story flats and duplex structure dating back to 1900. The building's permit history reveals several maintenance and improvement projects over the decades, including dry rot repair and bathroom renovations in 1989, reroofing that same year, a failed garage modification attempt in 1991, and sidewalk repairs in 2002. Recent issues in the immediate vicinity have primarily involved urban cleanliness challenges, with multiple reports of encampments (most recently in December 2024 and November 2023), and instances of human waste or debris requiring municipal intervention between 2022 and 2024. A construction-related noise and loose plate issue was reported and resolved in October 2023, though the specifics of the construction work were not detailed.

The building's fire incident record shows three alarm-related events, all occurring in 2023, including a false alarm, unintentional alarm activation, and a malfunctioning smoke detector - none of which resulted in civilian injuries. The frequency of encampment-related responses, with at least six documented cases between 2022 and 2024, and multiple reports of sidewalk cleaning needs including human waste removal, suggests ongoing challenges with the immediate street environment. While the building itself has undergone periodic maintenance and improvements, as evidenced by historical permits, the most pressing issues appear to be related to the surrounding public space rather than the structure itself.

Risk rating

How 3330 25Th 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
88th percentile

Out of 2380 buildings in this neighborhood, 286 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.

Neighborhood location

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

Neighborhood (ZIP code)

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

Building age

Older buildings tend to have more maintenance challenges; SF's pre-1906 earthquake housing stock carries distinct risk.

12-Month severity forecast
No violation 78.8%
Moderate concern 12.5%
Severe concern 8.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
