Initial analysis

The three-story mixed-use building at 2111-2115 Union Street in San Francisco's Cow Hollow neighborhood, owned by the Edwin L Mah Revocable Trust, was constructed in 1974 and contains three residential units above retail space. The property has undergone several significant renovations and modifications over the years, with the most recent activity in 2023 showing fire department intervention for hoarding and alarm system issues, both of which were corrected within nine days. In 2008, substantial improvements were made to the retail space, transforming it into a beauty salon and supply shop with accessible facilities, including electrical and plumbing upgrades totaling approximately $15,000. The ground floor commercial space has seen various conversions and improvements between 2001-2008, including attempts to switch from office to retail use, installation of awnings, and electrical upgrades.

The building's maintenance history includes one notable plumbing violation in October 2006 regarding a catch basin near the front door that required cleaning and maintenance, though this was abated by November 2006. The property has experienced some recurring street-level issues as documented in recent 311 calls, with reports of human waste and debris on the sidewalk, most recently in August 2024. While these exterior maintenance issues are noted, it's important to clarify that they pertain to the public right-of-way rather than the building itself. The property has maintained active compliance with city regulations, with all known violations and complaints having been resolved promptly.

Risk rating

How 2111-2115 Union 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.
