The property at 2026-2028 Green Street in Cow Hollow is a two-unit, two-story multi-family residential building constructed in 1880, currently owned by Benjamin F Tarnoff. The building has undergone several maintenance and improvement projects over the years, with the most recent significant work being a domestic water service replacement in 2011 and the installation of 13 recessed fixtures in the hallway in 2007. Earlier records show some structural work attempted in 1983 regarding basement wall removal, though that permit expired.

The building and its surroundings have experienced various maintenance issues in recent years, particularly regarding street cleanliness and waste management. Between 2023 and 2025, there were multiple reports (six documented 311 calls) about loose garbage, debris, and waste in the area, with the most recent incidents occurring in early 2024. A notable building complaint was filed in November 2020 concerning excessive noise from upstairs construction work, though this case is currently listed as not active. The property's utilities infrastructure has seen improvements over the years, including an underground conversion for PG&E service in 2003. Street space permits were issued in 2007 and 2018, suggesting some use of public space for building-related activities.

Risk rating

How 2026-2028 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.
