Initial analysis

The property at 216-218 Frederick Street is a two-story, four-unit multi-family residential building constructed in 1900 and currently owned by the John F. Ungar Revocable Trust. The building has undergone several significant improvements and maintenance work over the past decade, with the most recent activities focused on both structural and safety upgrades. Currently active permits indicate ongoing work to widen the garage door and reinforce garage and crawl space structures, as well as maintenance work on the south side dormer window including window replacement and siding repairs. Previous notable improvements include the 2012 renovation of the third floor to create occupiable space, bathroom modifications, and sprinkler system updates in 2011. The building has undergone regular maintenance of essential systems, including three water heater replacements (2019, 2022), sewer main line replacement (2018), and various bathroom renovations.

The property's safety systems have received consistent attention, with a complete sprinkler system installation and monitoring setup in 2011, though one related permit from 2011 is listed as expired. A fire alarm system complaint from August 2023 was resolved by September 2023 with the condition corrected. The building has a history of routine housing inspections dating back to 1996, with the most recent inspection activities not revealing any persistent violations. While there have been multiple 311 calls in the past year regarding street cleaning and debris removal, these issues appear to be primarily related to public space rather than building condition. Recent work and permits suggest active management of the property with ongoing improvements to maintain and upgrade building systems and features.

Risk rating

How 216-218 Frederick 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 581 buildings in this neighborhood, 320 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.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

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 55.0%
Moderate concern 23.8%
Severe concern 21.2%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
