Initial analysis

The two-unit residential building at 3966-3968 18th Street, located in the Eureka Valley/Dolores Heights neighborhood, is a two-story flats and duplex structure built in 1931 and currently owned by Dean C K Ng. The building's maintenance history shows several significant improvements, including a rear foundation wall raised by 8 inches in 2003 to address water seepage issues, a complete reroofing project in the same year, and a gas furnace and ductwork replacement in 2009. Two street space permits were issued in July 2007, though no associated costs were indicated.

Recent external conditions around the property have been challenging, particularly in the past two years. The most notable recurring issues have been instances of graffiti on the sidewalk in front of the property, with three documented cases between September and December 2023, all categorized as "Not Offensive" and requiring photo documentation and removal efforts by DPW. There have also been multiple reports of garbage and debris issues, including instances of human waste/urine and abandoned furniture, with the most recent occurring in 2024. The property area experienced two confirmed encampment situations in early 2021, though one was temporarily allowed to remain due to COVID-19 protocols. While the building itself has undergone necessary infrastructure improvements over the years, the surrounding public areas have faced ongoing maintenance challenges requiring regular attention from city services.

Risk rating

How 3966-3968 18Th 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.
