Initial analysis

The two-story multi-family residential building at 44-46 Winfield Street in Bernal Heights, owned by Margaret Brolan, was constructed in 1962 and consists of two units. The property has undergone several notable repairs and maintenance work over the years, most recently in 2023, when a rear yard retaining wall was repaired at a cost of $10,000. Previous significant improvements include the complete rebuilding of cantilever decks and replacement of rear patio doors in 2002, as well as the replacement of a 50-gallon water heater in 2007.

The building has experienced multiple plumbing and sewer-related issues, particularly during a concentrated period between October 2021 and January 2022. This timeframe saw several incidents of sewage backup and flooding, both on the property and in surrounding areas, including issues with catch basins and sewer vents. While these incidents were addressed through official city services and marked as resolved, the frequency and nature of these sewer-related problems suggest they may have impacted resident experience during that period. More recent structural work, such as the retaining wall repair in 2023, indicates ongoing maintenance of the property's infrastructure. The building's permit history shows regular attention to both structural and plumbing systems, though the significant cluster of sewer issues in late 2021 through early 2022 stands out as the most substantial maintenance concern on record.

Risk rating

How 44-46 Winfield 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

Out of 1276 buildings in this neighborhood, 64 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.

Neighborhood location

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

Neighborhood (ZIP code)

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

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 84.6%
Moderate concern 10.9%
Severe concern 4.5%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
