Initial analysis

The two-unit residential building at 21 Winfield Street in Bernal Heights is a two-story flats and duplex structure built in 1902, currently owned by Crandall SF Family Trust. The property has undergone several significant maintenance and improvement projects over the past two decades, with the most recent major works including a $15,675 re-roofing project and $20,000 front stairs repair in 2019. An extensive renovation took place in 2003, covering both units and the garage/basement, including kitchen remodeling, window replacements, and comprehensive electrical upgrades with new service installations.

The building has experienced multiple infrastructure and maintenance issues in recent years, particularly regarding external elements. There are currently three open 311 cases from 2023-2024 related to property concerns: one regarding damaged trees affecting both sidewalk and property conditions, one about sidewalk blockage from private vegetation, and one relating to a sidewalk defect (collapsed sidewalk). Historical documentation shows consistent attention to structural elements such as stairs and sidewalks, with particular focus on safety features like railings and emergency access points. While the building has maintained basic structural integrity through regular maintenance, the recent concentration of issues around the exterior infrastructure suggests ongoing challenges with the building's immediate surroundings. The property's permit history indicates proper legal channels have been used for major works, though no recent interior upgrades or improvements have been documented since the 2019 re-roofing and stair repairs.

Risk rating

How 21 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, 179 are predicted to be safer.

Construction spend, owner's portfolio

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

Building age

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

Neighborhood location

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