Initial analysis

The three-story multi-family residential building at 632-634 2nd Avenue in San Francisco's Inner Richmond neighborhood is a duplex property built in 1905, currently owned by the Donna Chan 2017 Living Trust. The building has undergone several significant improvements and maintenance work over the past decades, with the most notable being a dry rot repair project in 2011 that involved replacing three windows, a patio door, and affected siding at a cost of $12,000. In 2008, substantial plumbing upgrades were completed, including the installation of two roof drains, three drinking fountains, and ADA-compliant showers on the second and third floors, along with sink and lavatory installations. The building underwent substantial electrical work in 2008, including the installation of various lighting, switch, and receptacle setups, as well as furniture connections and horn/strobe systems.

The property has experienced recurring issues with illegal parking, particularly in 2024, with multiple reports of driveway blocking incidents resulting in citations, including at least eight documented cases between May and October 2024. There were also three completed work permits in 2012 for electrical upgrades, including a modular office furniture installation and a cancelled 400-amp panel project. The building has a relatively clean maintenance record beyond the parking issues, with all other documented permits showing either completed or resolved status. A recent 311 call in January 2025 reported an abandoned refrigerator appliance issue that was resolved as a private property matter.

Risk rating

How 632-634 2Nd 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
62th percentile

Out of 1723 buildings in this neighborhood, 655 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.

Estimated permit spend (past 7 years)

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

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

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 83.4%
Moderate concern 11.3%
Severe concern 5.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
