Initial analysis

225 Diamond Street is a two-unit residential building located in the Eureka Valley/Dolores Heights neighborhood, owned by the Estate of Walter Delany Norris. The 1900-built structure has experienced several significant maintenance and compliance issues over its history, with the most recent concerns emerging in mid-2024 regarding illegal construction and debris. Between 2019-2023, the building faced multiple violations including inadequate heating, electrical problems, plumbing leaks, and various safety concerns. These violations were officially abated by December 2023, following multiple Notices of Violation and a director hearing in June 2019.

The property has undergone various permitted modifications, with the most recent significant proposed change (filed September 2024) being the conversion of ground floor storage into an additional residential unit, adding interior stairs and additional bathroom and bedroom facilities. Previous work included addressing a host of compliance issues in 2011 related to illegal kitchen removal, shed removal, and various repairs under an expired permit, though this followed multiple violations from 2006-2010. The building's maintenance history indicates recurring heating system problems (2012-2019), electrical issues (2013), and various safety concerns including non-functional smoke detectors, water leaks, and lighting problems. The property has also seen some fire safety concerns, with a violation for storage/combustibles issued in October 2010. Recent complaints in 2024 suggest continuing issues with unauthorized construction work and potential debris management concerns, though these complaints are currently listed as not active.

Risk rating

How 225 Diamond 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 1278 buildings in this neighborhood, 51 are predicted to be safer.

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.

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.

12-Month severity forecast

Moderate concern 11.0%
Severe concern 7.1%
