Initial analysis

The three-story multi-family residential building at 346 28th Avenue in the Central Richmond neighborhood, owned by Ruan Qi Xian Danny & Yuan Q, was constructed in 1912 and contains two units. The property underwent significant renovation in 2001-2004, including a substantial $240,000 project to raise the building for parking access, extend the rear, and add a secondary dwelling unit. This renovation phase included structural modifications such as replacing steel beams with glulam beams at the first floor, electrical system upgrades including complete rewiring of the building with new 125-amp meters, and installation of new garage door facilities, which were completed between 2003-2006. These improvements were properly permitted and completed, with all associated electrical permits ultimately cleared, though some expired initially before being renewed and finalized.

The building's more recent history (2018-2024) shows relatively few building-specific issues, with most recorded incidents being street-level concerns rather than direct building problems. These include several parking enforcement actions in July 2021 related to a black Jeep, a water leak/other sewer issue reported in August 2014, and various street cleaning matters including garbage, debris, and waste reports in 2019 and 2024. An encampment issue reported in April 2018 was resolved, and while there was one building-related electrical permit that expired in 2004, it was subsequently renewed and completed in 2006, marking the conclusion of the major renovation period for the building.

Risk rating

How 346 28Th 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
72th percentile

Out of 2250 buildings in this neighborhood, 630 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.

Neighborhood location

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

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 77.6%
Moderate concern 19.4%
Severe concern 3.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
