Initial analysis

The property at 218 21st Avenue is a two-story multi-family residential building located in San Francisco's Central Richmond neighborhood, owned by Jane C. & Norbert H. Groeger Revocable Trust. Built in 1913, this flats and duplex building has undergone several significant improvements over the past few years, with the most recent work including electrical upgrades in July 2024, featuring the installation of an electric power box and a panel upgrade correction. Between 2019 and 2022, the building received substantial modernization, including a comprehensive window replacement project in late 2022 costing $7,850, where seven windows were replaced with energy-efficient units meeting U-factor requirements, and a bathroom renovation in 2019 that involved replacing an existing tub with a walk-in jet tub and associated electrical work.

The building's infrastructure improvements have focused on safety and efficiency, with a 200-amp electrical system upgrade completed in late 2019 that involved installing two meters and replacing an outdated 60-amp fuse panel, along with additional electrical work for new circuits. While the property has seen significant maintenance and upgrading work, there were two street cleaning complaints in November 2020 regarding loose garbage, which were resolved. A roof replacement was completed in March 1992, though this work is now quite dated. The building's recent improvements suggest active maintenance and modernization by the current ownership, with particular attention to electrical systems and energy-efficient upgrades.

Risk rating

How 218 21St Ave'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
72th percentile

Out of 2250 buildings in this neighborhood, 630 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.

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.

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 77.7%
Moderate concern 19.9%
Severe concern 2.4%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
