Initial analysis

The three-story, six-unit multi-family residential building at 1661 Greenwich Street in Cow Hollow, built in 1906 and currently owned by the Tom Anne Lee Bypass Trust, has a mixed record of maintenance and safety compliance over the past decade. Most concerning is an active building complaint filed in August 2023 regarding exposed wiring and dilapidated awnings, which are reported to be in such poor condition that they may present safety and mold hazards. The building's record shows regular safety inspections were conducted in 1995, 1999, and 2016, though the outcomes of these inspections are not detailed in the records. An earlier building permit from 1998 for reroofing work appears to have expired without confirmation of completion.

The property has generated multiple 311 calls in recent months, with ten separate reports between August 2024 and January 2025 related to garbage and debris issues in the vicinity, though these appear to be primarily street cleaning matters rather than direct building maintenance concerns. Additionally, there have been two fire alarm incidents recorded, both of which were determined to be false alarms or system malfunctions with no civilian injuries reported.

Risk rating

How 1661 Greenwich 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 861 buildings in this neighborhood, 749 are predicted to be safer.
