Initial analysis

The three-story multi-family residential building at 469-471 Diamond Street, owned by Thomas Nielsen, consists of two units and is located in the Eureka Valley/Dolores Heights neighborhood. The property has undergone several significant improvements over the past decade, with the most recent building permits showing a missing side sewer vent cover as of August 2023. In 2020, the building received a reroofing renovation, while substantial exterior work was completed in 2018, including rear yard landscaping with walls, steps, and lighting improvements valued at $40,000. Earlier improvements from 2017 involved replacing 14 leaking windows with wood-clad aluminum units, and in 2010, the building underwent comprehensive interior updates, including electrical system modernization across all floors, HVAC system upgrades with new furnaces and ducting, bathroom renovations, and kitchen remodels in both units.

The property's maintenance history suggests regular upkeep and modernization efforts, with particular attention to windows, siding, and landscaping. The building's façade has received specific attention over the years, with permits showing stucco siding replacement and window upgrades. While there have been multiple reports of abandoned vehicles in the vicinity between 2011 and 2019, these were external issues not directly related to the building's condition. The current outstanding issue from 2023 regarding the missing side sewer vent cover is the only recent infrastructure concern on record, representing a relatively minor maintenance matter compared to the building's overall improvement history. The property has successfully navigated various building, plumbing, and electrical permits since 2010, indicating compliance with necessary codes and regulations during improvement projects.

Risk rating

How 469-471 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
97th percentile

Out of 1278 buildings in this neighborhood, 38 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.

Estimated permit spend (past 7 years)

Dollar value of permits pulled at this address — large recent spend can signal deferred-maintenance catch-up.

12-Month severity forecast
No violation 86.1%
Moderate concern 10.1%
Severe concern 3.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
