Initial analysis

The 6-unit, 3-story apartment building at 770 Natoma Street, built in 1907 and currently owned by Natoma LLC, has undergone numerous significant renovations and faced several critical issues over the past two decades. Most notably, the building has an active Soft Story violation (Tier 4, filed December 2022) for failing to complete mandatory seismic retrofit work, which includes ongoing soil stabilization efforts with permeation grouting at the foundation footing scheduled for 2024 (permit cost: $8,833). The building has experienced various structural and maintenance challenges, including water leak complaints in 2008 and 2009, multiple building code violations in 2004 (resolved), and a 2020 complaint regarding unauthorized structural work at the rear of the building.

Recent improvement activities include significant interior and infrastructure upgrades: the building underwent major electrical system improvements in 2011-2013, including new 90-amp panels for all units, and comprehensive plumbing upgrades including gas line installations and the replacement of wall furnaces in all units. The property has been actively undergoing modernization efforts, including attempts to add an ADU in the basement and convert the ramped basement area into a garage, though these efforts have encountered various permitting challenges and remain in various states of review or hold as of 2024. Despite these ongoing improvements, the building's non-compliance with Soft Story requirements remains a significant concern, particularly as it pertains to earthquake safety.

Risk rating

How 770 Natoma 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.
