Initial analysis

The property at 4382-4384 17th Street in Corona Heights is a two-unit, two-story multi-family residential building constructed in 1908 and owned by Adrian J Bernhardi Swingler. Recent maintenance and improvements include the replacement of nine front windows in 2021 with wood double-hung windows featuring integrated ogees, completed at a cost of $16,900. The building has undergone several structural and cosmetic improvements over the years, including garage door replacement in 2013, remodeling of kitchen and bathroom facilities in 1999, and roofing work in 1997. The building experienced significant water-related issues in 1994, with multiple complaints about roof leaks and interior damage, though these problems were marked as abated by 1995. More recently, in November 2023, there were sewer-related incidents requiring emergency response involving both a sewage backup and waste cleanup on the property.

The property has a history of parking-related issues in the vicinity, with multiple 311 calls about sidewalk parking and driveway blocking between 2023 and 2024, though most of these incidents could not be validated by responding officers. A fire alarm system issue was reported and corrected in July-August 2024. The building appears to have maintained structural integrity since the resolution of the 1994 water issues, with recent improvements focusing on exterior maintenance.

Risk rating

How 4382-4384 17Th 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
78th percentile

Out of 348 buildings in this neighborhood, 77 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.

Construction spend, owner's portfolio

Estimated permit value across all of this owner's buildings.

Neighborhood location

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

12-Month severity forecast
No violation 76.6%
Moderate concern 14.4%
Severe concern 9.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
