Initial analysis

The two-unit, two-story multi-family residential building at 3270 Harrison Street in Bernal Heights, owned by Mary Ann Chavez, has a lengthy history since its construction in 1900. The property experienced significant maintenance and safety issues in early 2016, when multiple building violations were documented, including problems with electrical fixtures, electrical systems, stairs, and lead-related concerns, along with requirements to replace hollow core entry doors and paint walls, trim, and front stairs. These violations were all addressed and abated by March 17, 2016. The building also underwent plumbing work in 2023 with the replacement of two furnaces, though this permit has since expired. An electrical permit from 2016 related to bathroom electrical modifications has also expired.

More recent activity at the property includes multiple parking-related incidents recorded through 311 calls in 2023-2024, primarily involving abandoned vehicles and driveway blocking issues, though these are external to the building's condition and maintenance history. The frequency of parking violations in the immediate vicinity suggests ongoing challenges with street parking in the area. The building's age and permit history indicate some investment in maintenance and upgrades over time, though the expired permits suggest there may be some work that remains incomplete. Notably, there are no documented tenant buyouts at this address, and the last major concern regarding building violations dates back to 2016, suggesting that the property has been relatively stable in recent years, from a violations perspective.

Risk rating

How 3270 Harrison 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
92th percentile

Out of 1276 buildings in this neighborhood, 102 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 (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.

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 85.1%
Moderate concern 9.6%
Severe concern 5.3%
