Initial analysis

The property at 2784-2786 Diamond Street in Glen Park is a two-unit, two-story multi-family residential building with retail space, built in 1916 and currently owned by Frank C Walsh & John J Jenn. The building has undergone several significant improvements and maintenance work over the years, with the most recent being the installation of a door operator power system in 2023-2024 to comply with accessibility requirements. The property experienced a notable fire incident in 2007 that required substantial repairs including roof replacement, bathroom and kitchen fixture updates, and window replacements. That same year, major renovations were completed including new windows installation, tenant improvements for an optometrist office, and comprehensive electrical system upgrades.

The building's infrastructure has received regular updates, including plumbing work such as house trap replacement in 2015 and various HVAC and electrical improvements in 2007.

Risk rating

How 2784-2786 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
40th percentile

Out of 364 buildings in this neighborhood, 218 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.

Property class: apartment building

Apartment building — this property classification influences expected violation rates.

Neighborhood location

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

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 78.9%
Moderate concern 17.2%
Severe concern 3.9%
