Initial analysis

The 2218 20th Street property in Potrero Hill is a two-story, three-unit multi-family residential building constructed in 1918, currently owned by the Drefke Shinbori Trust. The building's most significant maintenance and safety issues occurred in December 2002, when multiple violations were filed regarding various safety and maintenance concerns including problems with handrails, stairs, smoke detectors, and interior surfaces. These violations were all addressed and officially abated by August 2003, along with additional repairs completed in 2003 concerning handrails, stairs, and smoke detector replacements. The electrical system received updates in 2004-2005 with the installation of a 100-amp service and various electrical fixtures, though these permits have since expired. More recent building maintenance records from 2012 and 2018 indicate minor street space and sidewalk work.

The property has experienced some exterior maintenance issues over time, including reports of graffiti in 2022-2024, though these were primarily affecting utility and city property rather than the building itself. While there were some historical concerns about electrical wiring, plumbing leaks, and deck issues in 2002, these have been documented as resolved. The building's immediate surroundings have seen various municipal service requests, including for graffiti removal and maintenance of city property, which were all properly addressed. A separate planning record from 2220 20th Street confirms a short-term rental violation that was subsequently abated. The most recent significant transaction related to the property's vicinity was a tenant buyout at 790 Kansas Street in December 2017, involving two tenants and a payment of $40,000.

Risk rating

How 2218 20Th 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
53th percentile

Out of 726 buildings in this neighborhood, 341 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.

Building permits, owner's portfolio

Permits pulled across all of this owner's buildings over 7 years.

12-Month severity forecast
No violation 54.5%
Moderate concern 30.5%
Severe concern 15.0%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
