Initial analysis

The property at 338 San Carlos Street in San Francisco's Inner Mission neighborhood is a single-story, three-unit multi-family residential building constructed in 1937 and currently owned by the Shao Yun Zhao Trust. The building has experienced several concerning maintenance and safety issues over its history, with the most critical problems occurring between 2003 and 2008. During this period, multiple violations were documented in September 2003, including security concerns (self-closing devices at exterior doors), fire safety (smoke enclosure door repair), and sanitation issues, all of which were later addressed. A significant cluster of problems was reported in August 2008, when complaints about mold, window issues, and various maintenance problems prompted a routine inspection, leading to the discovery of unauthorized construction (an exterior roof covering) that was subsequently addressed through a permit (completed in 2008) to repair stairs and address the roof issue. The building's earlier history includes various improvements and repairs, such as stair repairs and window installations in the late 1980s and early 1990s.

More recently, the property has faced infrastructure challenges in the surrounding area, with multiple 311 calls in 2023-2024 regarding sidewalk defects, tree root damage to sidewalks, and instances of loose garbage on the street. While these external issues don't directly impact the building's habitability, they do affect the property's immediate surroundings. The most recent building-related permits and violations indicate that major structural and safety issues have been largely addressed, with no active violations on record since 2016. However, the pattern of maintenance issues and violations from 1994 through 2008 suggests that prospective tenants should remain vigilant about ongoing maintenance matters, particularly regarding the building's age and historical repair history.

Risk rating

How 338 San Carlos 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
72th percentile

Out of 2380 buildings in this neighborhood, 666 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.

Construction spend, owner's portfolio

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

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 70.2%
Moderate concern 19.0%
Severe concern 10.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
