Initial analysis

The property at 1254-1256 20th Avenue in San Francisco's Central Sunset neighborhood is a two-unit, two-story multi-family residential building constructed in 1909, currently owned by Dean J. Whittaker. The building has undergone several significant renovations over the past few decades, with the most recent being a comprehensive kitchen remodel completed in 2016 that included electrical upgrades, cabinet replacements, and new appliances. Prior improvements include a bathroom renovation in 2011 featuring new fixtures, lighting, and compliance upgrades. Earlier maintenance records show work on gas lines in 1996 and a reroofing project from 1998, though these permits have since expired.

The property has experienced persistent issues with parking violations in recent months, with multiple citations issued for blocked driveways throughout 2023-2024, though these are external to the building itself. There have also been occasional reports of garbage and debris on nearby streets, including an incident involving electronics and another case of human waste reported in late 2024, though these were resolved without requiring further action. While these external cleanliness and parking issues are worth noting, the building's interior appears to be well-maintained based on the record of recent improvements and compliance upgrades, with no documented safety violations or major maintenance concerns on file.

Risk rating

How 1254-1256 20Th 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
48th percentile

Out of 814 buildings in this neighborhood, 423 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 76.6%
Moderate concern 18.3%
Severe concern 5.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
