Initial analysis

The property at 642-644 11th Ave in the Inner Richmond is a two-story, multi-family residential building constructed in 1915, containing three units and currently owned by the Daniel C & Alice Wai Rvc Trust. The building has experienced several significant events, with the most recent being plumbing work completed in March 2023 involving modifications to the front water meter installation. The building's history shows two instances of fire-related events in 1988-1989, requiring repairs but no structural changes. A notable set of violations occurred in 2017 during a routine safety inspection, highlighting various safety and security issues including the need for carbon monoxide alarms, fire extinguishers, and the removal of egress obstructions; all these violations were abated by April 2017. The building underwent joist repairs at the rear in 2010, and has had various window and kitchen cabinet modifications over the years.

Recent activity around the property has been dominated by parking-related issues, with multiple 311 calls between 2023-2024 regarding sidewalk parking and driveway blocking, suggesting ongoing challenges with parking enforcement in the area. Two false fire incidents were recorded with no civilian injuries reported. The building's inspection history shows regular oversight by Housing Inspection Services, with annual routine inspections between 2002-2017 indicating active monitoring of building conditions. While the property has experienced some maintenance issues over the years, particularly noted in the 2017 violations, records show that these issues have generally been addressed promptly once identified.

Risk rating

How 642-644 11Th 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.

Model explanation

What's driving this score

Estimated permit spend (past 7 years)

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

Construction spend, owner's portfolio

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

12-Month severity forecast
No violation 71.0%
Moderate concern 19.2%
Severe concern 9.8%
