Initial analysis

The two-story multi-family residential building at 1511 6th Avenue in the Inner Sunset, owned by the James D Holthaus Trust, was constructed in 1915 and contains 4 units. The building's maintenance history includes a reroofing project completed in 1995, though more recent maintenance records are limited. In July 2005, the property was the subject of housing violations requiring attention to stairs and exterior door security, which were successfully resolved by September 2005. A routine housing inspection occurred in 2010, and while a complaint from February 2000 remains listed as active, it is not clear from the records what this pertains to as no details were provided.

The most significant recent activity involves numerous 311 calls between September 2024 and January 2025, primarily relating to street and sidewalk conditions around the property. These calls include reports of abandoned furniture, garbage and debris, illegal postings, vehicle issues, and two instances of graffiti - one of which was an offensive public display that was promptly addressed by city crews. The building's history includes one smoke-related incident, though this was limited to a smoke scare with no civilian injuries reported. While the property has experienced periodic maintenance issues and neighborhood concerns over the years, most historical violations were addressed promptly, suggesting reasonable responsiveness to building code requirements.

Risk rating

How 1511 6Th 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
41th percentile

Out of 1493 buildings in this neighborhood, 881 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 location

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

Building age

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

12-Month severity forecast
No violation 45.4%
Moderate concern 19.3%
Severe concern 35.3%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
