Initial analysis

The two-story, four-unit multi-family residential building at 1414-1420 17th Avenue in San Francisco's Inner Sunset neighborhood was constructed in 1947 and is currently held in trust by Tam Marital. The building's maintenance history shows several significant repairs over the past few decades, most notably in the early 2000s when attention was required for safety elements. In 2005, the rear stairs (designated as second egress) were replaced due to damage, and in 2008, repairs were made to address deck dry rot, though notably this issue involved areas not visible from the street and affected less than 50% of the structure. The building has undergone regular maintenance tasks including a complete reroofing in 1991 and a building code compliance update in 1984. Routine housing inspections of common areas have been conducted in 1995, 2001, and most recently in 2011, with all issues promptly abated on the same day they were filed. While the building has experienced periodic maintenance needs, the prompt response to repairs and completion of necessary updates suggests regular upkeep of the property over the years.

Risk rating

How 1414-1420 17Th 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 1493 buildings in this neighborhood, 1239 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Neighborhood location

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

12-Month severity forecast

Moderate concern 20.7%
Severe concern 35.9%
