Initial analysis

The property at 815-821 Greenwich Street in Russian Hill is a two-story multi-family residential building constructed in 1962, currently owned by Pathmark Group LP. The building has undergone significant and controversial development activities in recent years, including an attempted vertical addition and interior remodel in 2017 to increase units from 3 to 5 and a 2021 permit application to add an ADU with bedroom, bathroom, and kitchen. Most concerning is a December 2024 complaint alleging unauthorized transformation into a 24-room SRO, with reports of hazardous construction practices including debris and appliance disposal without proper safety measures. The building's systems are undergoing substantial upgrades, with plumbing permits issued in May 2024 for 11 shower pan replacements and 7 furnace installations, along with electrical work to upgrade service to 400-amp with new subpanels and circuits.

The property has a history of maintenance issues and violations, particularly in 2016, when inspections revealed multiple problems including malfunctioning light fixtures, electrical issues, and plumbing concerns including sewer problems and non-compliant dryer venting. Historical records show various improvements including reroofing work in 1989, 1994, and most recently in 2015. Building complaints have been filed over the years regarding various issues, including a 2021 fire hazard complaint about storage conditions and multiple inspection-related issues requiring attention. More recent 311 calls from 2024 indicate problems with the building's sidewalk, described as collapsed, which has been temporarily resolved but remains a concern. While some building improvements have been properly permitted and completed, the most significant recent concerns appear to be related to unauthorized unit conversions and construction activities, though many of these complaints have been marked as "Not Active" after investigation.

Risk rating

How 815-821 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.
