Augrented Insights

Initial analysis

The three-unit, three-story multi-family residential building at 1228-1232 12th Avenue in the Inner Sunset, built in 1904 and currently owned by Steve Shao Ta & Yolanda Ban, has undergone several significant maintenance and repair events over its history. The most recent major work was a reroofing project completed in 2021 at a cost of $12,800. The building experienced substantial maintenance issues in 2010, when multiple violations were recorded and subsequently addressed, including problems with bathtub tiles, bathroom paint, windows, and the front entry door, all of which were abated by September 17, 2010. Other notable improvements include a complete gas line replacement for the whole unit in 2014, repairs to dry rot damage in the rear stairs in 1993, and ceiling joint replacements in unit 1232 from 1987.

The building's recent history shows proper attention to maintenance, with no active violations or complaints since 2010. A routine safety inspection was conducted in March 2011, and the only recorded fire incident was an unintentional alarm transmission with no civilian injuries. The most recent external incident was a parking enforcement issue in 2019. The property has maintained compliance with housing codes since addressing the 2010 violations, suggesting improved maintenance protocols, though the clustered nature of the 2010 violations indicated a period of significant disrepair requiring coordinated remediation efforts.

Risk rating

How 1228-1232 12Th 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

25th percentile

Out of 1493 buildings in this neighborhood, 1120 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.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

12-Month severity forecast

No violation 70.6%

Moderate concern 23.3%

Severe concern 6.1%

Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
