Initial analysis

The property at 472-474 19th Avenue is a two-unit, two-story multi-family residential building located in San Francisco's Central Richmond neighborhood. Built in 1913 and currently owned by the Mabel Fan Ng Living Trust, this flats and duplex structure has recently undergone significant exterior improvements. In mid-2023, the building received substantial siding work, including a series of permit approvals showing the replacement of rear wood siding totaling 900 square feet and associated revisions, with construction values totaling $10,000. Historical records show various permitted improvements from the mid-1990s, including attempts to work on a lightwell and rear yard retaining wall, though some of these permits ultimately expired.

The property has experienced recurring issues with parking violations in the immediate vicinity, particularly in 2023-2025, with multiple reports of vehicles parking on sidewalks, though most were either unable to be located or resolved through official warnings. In late 2019, there were several reports of abandoned vehicles in the area, though investigators were unable to validate most of these claims, with one vehicle found in compliance with parking regulations. Historical planning records indicate a rear addition to the building that was approved and constructed, suggesting ongoing investment in maintaining and improving the property.

Risk rating

How 472-474 19Th 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 80.2%
Moderate concern 17.1%
Severe concern 2.7%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
