Initial analysis

The 9-unit multi-family residential building at 601 Stockton Street is a 3-story apartment constructed in 1919, currently owned by Lee Thomas. The building has undergone regular maintenance, with the most recent completed work being a $10,000 reroofing project in April 2024. Historical records show a pattern of roof maintenance, with previous reroofing work done in 1991 and 1992. The building has faced several safety and maintenance challenges over the years, particularly during a cluster of violations in 2000-2007, which included multiple fire safety issues such as problems with fire escape ladders, fire proofing materials, combustible storage, and fire alarm systems. While these violations were all marked as abated by June 2007, there was a subsequent complaint in 2010 regarding mold and water damage in Unit #4, and a 2016 complaint about construction-related disturbances from a nearby project.

The building has maintained a pattern of addressing fire safety issues, with several fire-related violations and complaints documented between 2006 and 2022, including problems with fire extinguishers and alarm systems, all of which were corrected. There have been no reported civilian injuries from fire incidents at the address, though there have been multiple false alarms and medical assistance calls recorded through fire department responses. Recent concerns at the property have primarily centered around parking issues, with multiple parking violation complaints filed between December 2024 and January 2025, though enforcement responses were generally unable to locate the offending vehicles. A tenant buyout notice recorded at 725 Pine Street in 2018 involving two tenants appears unrelated to this address, and no active tenant buyout offers are currently on record for this building.

Risk rating

How 601 Stockton 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

Building size

Total floor area — a proxy for building scale and the number of systems (plumbing, electrical, HVAC) that can fail.

Number of units

The number of units affects how the model reads complaint and violation totals — more units means more potential sources.

Neighborhood (ZIP code)

The ZIP code captures local housing market and enforcement patterns that affect all buildings in the area.

Moderate concern 73.5%
Severe concern 14.6%
