Initial analysis

The two-story multi-family residential building at 4105-4121 19th Street, owned by the Boyd M Swartz Revc Trust, was constructed in 1904 and contains 9 units, plus commercial space. The property has recently undergone barrier remediation work in September 2023, with permits filed to install accessibility features including signage and a buzzer system. These improvements were required to address ABE compliance. The building's history includes several notable events: in 1983, the residential space was converted to office use, and there was a significant plumbing infrastructure upgrade in 2013 involving the replacement of the building's house trap and sidewalk sewer lines. Two housing inspection complaints were filed in 1994 regarding unauthorized commercial use of residential units, though these were resolved within a month of filing.

The property has experienced recurring issues with street cleanliness and garbage management in recent years, particularly throughout 2024, with multiple 311 calls regarding loose garbage, debris, and waste management. These include eight separate reports of general cleaning concerns and one instance of toters being left out continuously, with varying outcomes from resolved cases to one currently open case (as of May 2024). While these sanitation issues primarily relate to exterior maintenance rather than building conditions, they may affect resident comfort in common areas. The building's commercial space has been home to several notable businesses, including Yankee Clipper Travel and Castro Village Wine Company, and has undergone various improvements and permits for business-related changes, such as the installation of an assistance buzzer and signage for ABE compliance.

Risk rating

How 4105-4121 19Th St'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
10th percentile

Out of 1278 buildings in this neighborhood, 1150 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 53.6%
Moderate concern 15.9%
Severe concern 30.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
