Initial analysis

The two-unit residential building at 4009-4011 Irving Street in San Francisco's Outer Sunset neighborhood, owned by Zhu Jun & Yuan Zhi Qiong, has undergone several notable infrastructure improvements over the past few decades. The property, built in 1910 and classified as a Flats & Duplex building, received significant electrical system upgrades in 2019 with the installation of new 200-amp service and two meters, along with proper grounding. Earlier improvements included window modifications in 1991, though an attempted reroofing project from 1997 appears to show as expired in the records. The most recent street space permit was issued in 2020, though it carries no associated cost.

The building's surroundings have experienced numerous issues requiring municipal attention, particularly in recent years. Between 2022 and 2025, there have been persistent problems with illegal parking, including two documented cases of driveway blocking in 2023 that resulted in citations. The area has also faced recurring sanitation challenges, with multiple incidents of garbage and debris requiring city intervention, including the removal of a refrigerator in late 2024. Public safety concerns were documented in 2022 with the discovery of medical waste (needles) on the street, though this was promptly addressed. Other reported issues have included abandoned vehicles, damaged property (specifically a sign), and general street cleaning needs, all of which were resolved by the respective agencies. The frequency and variety of these exterior maintenance issues suggest ongoing challenges in the immediate vicinity, though most appear to be promptly addressed by city services.

Risk rating

How 4009-4011 Irving 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
68th percentile

Out of 632 buildings in this neighborhood, 202 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.

Building age

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

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

12-Month severity forecast
No violation 71.2%
Moderate concern 24.1%
Severe concern 4.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
