Initial analysis

The property at 331 25th Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Central Richmond neighborhood. Built in 1915 and classified as a Flats & Duplex building, it is currently owned by Raymond M Quan Bypass Trst. Over the past two decades, the building has undergone several permitted improvements, including a kitchen renovation in 2010 ($2,500) and electrical upgrades in 2006 involving the installation of three meters, one light, and four receptacles. A street space permit was also issued in 2004.

The building's maintenance and incident record reveals some ongoing concerns, particularly with tree-related issues, which have been a recurring theme from 2016 through 2021. These include problems with overgrown trees blocking sidewalks, property damage from trees, and various maintenance needs that were primarily resolved through the city's StreetTreeSF program. More recently, in 2021-2022, there have been two documented water-related incidents near the property involving a fire hydrant and street flooding, though these were not directly related to the building's infrastructure. The property's unit count and historical permit activity suggest reasonable maintenance and improvement efforts by ownership, with particular focus on electrical infrastructure and interior upgrades.

Risk rating

How 331 25Th 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 2250 buildings in this neighborhood, 1282 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.

Building age

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

Construction spend, owner's portfolio

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

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 78.2%
Moderate concern 17.3%
Severe concern 4.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
