Initial analysis

The 5-unit, 2-story multi-family residential building at 771 9th Avenue in the Inner Richmond, owned by Yu Hsun Ming & Hao Hsiao Ch, was constructed in 1918 and has undergone several significant safety and maintenance improvements over the past decades. Most recently, in 2020, the building received a fire alarm system upgrade including low-frequency sounders, radio, and monitoring for $12,000, with the work now properly completed under both building and electrical permits. The property is classified as a Tier 3 Soft-Story building, and the required seismic retrofitting work was completed with a Certificate of Final Completion issued.

The building has experienced several maintenance and safety issues in recent years, including a 2016 complaint about lack of hot water and gas service, and multiple building violations in 2010-2011 related to security, fire safety, and general maintenance, all of which were abated by July 2011. Substantial improvements have been made to address these issues, including a soft level retrofit in 2016, gas service repairs, and various plumbing updates including a house trap replacement in 2011. The building has a documented history of addressing structural and safety concerns, such as a 1996 stair and decking repair, 1988 stucco replacement, and multiple unit improvements including a 2006 kitchen and bath remodel in Unit #1. The property maintains active compliance with safety regulations, as evidenced by the recent fire alarm system upgrades and successful completion of the soft-story retrofit requirements.

Risk rating

How 771 9Th 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.

Neighborhood percentile

Out of 1723 buildings in this neighborhood, 1309 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.

Number of units

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

Building age

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

Neighborhood location

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

12-Month severity forecast
No violation 67.6%
Moderate concern 17.1%
Severe concern 15.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
