Initial analysis

The property at 595 Diamond Street is a two-unit, two-story multi-family residential building located in Noe Valley, built in 1912 and currently owned by Pennell Trust. The building has undergone significant improvements in recent months, with major renovations completed in 2023-2024 including a comprehensive interior remodel of both units (valued at $341,000) featuring kitchen and bathroom updates, addition of one full bath, replacement of water heater and furnace, basement strengthening, and installation of washer/dryer facilities. Additional improvements have included the replacement of 33 windows with Marvin Ultimate aluminum-clad wood windows, electrical system upgrades including fire warning devices and a 200-amp service upgrade, and plumbing work including new water service and bathroom/kitchen relocations. A new deck over the existing garage roof has also been constructed.

The building's recent history shows a proactive approach to maintenance and upgrades, though there are some ongoing concerns in the vicinity. These include an open sidewalk defect case from June 2022 regarding a collapsed sidewalk, and parking enforcement issues noted in 2023-2024 with incidents of sidewalk parking and double parking. A graffiti incident was reported in April 2023, though resolution was complicated by COVID-related enforcement suspensions. The property has maintained proper response to building-related issues, with all recent permits marked as complete and no building code violations on record. The extensive renovations and upgrades suggest significant investment in improving both the safety and comfort of the building's units, though prospective tenants should be aware of the building's age and the property's ongoing urban neighborhood context.

Risk rating

How 595-597 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 1879 buildings in this neighborhood, 19 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.

Building age

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

Neighborhood (ZIP code)

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

12-Month severity forecast
No violation 89.5%
Moderate concern 8.4%
Severe concern 2.1%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
