Initial analysis

The three-story multi-family residential building at 2048 Green Street in Cow Hollow, owned by Kao Chung Cheng & Lin Su Ch, was constructed in 1905 and contains 4 units. The property has undergone several significant improvements over the years, including fire sprinkler system upgrades in 1999, a solar panel installation in 2011 (13 roof-mounted PV modules), and a backflow assembly installation in 2016. The building has a history of fire safety-related violations and inspections, with notable issues in 2000 and 2016 regarding fire extinguishers, smoke detectors, carbon monoxide alarms, and egress obstructions, all of which were subsequently abated. In 2016, there was a violation concerning combustible materials, and in 2017, an alarm system issue was corrected promptly.

The property experienced unauthorized short-term rental activity that generated neighborhood concerns, leading to two violations in 2017 and 2018, though these were ultimately abated. Historical improvements include horizontal/vertical additions completed in 1991 and 1998. The building has maintained compliance with housing inspections since 2001, with no active violations on record. Recent activity at the address has primarily consisted of routine street-related issues, including several parking enforcement calls and sidewalk maintenance concerns, though these are external to the building's condition and safety status.

Risk rating

How 2048 Green 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.
