Initial analysis

The three-unit, three-story multi-family residential building at 378-382 Frederick Street, owned by Michael W & Elena B Stephen, has undergone several significant maintenance and improvement projects since its construction in 1900. The property has seen substantial updates in recent years, including a complete electrical rewire and new circuits installation in the top floor unit (2021), galvanize pipe replacement (2017), console heater replacements (2013), and multiple window replacements, most notably a 27-window retrofit in 2015 with energy-efficient vinyl frames. Structural improvements include reroofing projects completed in 2015 and 1993, stair repairs in 2015 addressing rotted boards, and routine maintenance such as street space permits in 2019 and 2017.

The building's inspection history shows three routine inspections conducted in 2003, 2008, and 2017, with all issues being promptly addressed and abated. In 2003, violations were documented regarding stair repairs and garbage receptacle placement, but these were resolved within two months. The most recent maintenance record includes multiple 311 calls related to street and sidewalk issues, such as graffiti (2025, 2023), parking violations (2022), and general street cleaning needs (2021). A damaged tree was removed and ground in December 2020. The property has maintained compliance with housing and safety regulations, with no active violations on record, and has received ongoing attention to infrastructure maintenance and upgrades over the years.

Risk rating

How 378-382 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
41th percentile

Out of 526 buildings in this neighborhood, 310 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.

Estimated permit spend (past 7 years)

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

Property class: multi-family flat

2–4 unit flats (class F) are a common SF building type with their own maintenance and complaint patterns.

12-Month severity forecast
No violation 53.1%
Moderate concern 23.1%
Severe concern 23.8%
Estimated probability of receiving a DBI Notice of Violation in the next 12 months at each severity level. Model: full_hgb_balanced.
