Initial analysis

The 10-story, 69-unit apartment building at 645 Stockton Street, constructed in 1928 and currently owned by Lsl Properties B14 De Llc, has undergone significant recent renovations. Between 2020-2022, multiple units (303, 502, 704, 807, and 1004) received comprehensive upgrades including kitchen and bathroom rehabilitation, bedroom conversions, and washer/dryer installations, with costs ranging from $45,000 to $68,000 per unit. However, the building has experienced several concerning issues recently, particularly in late 2024 and early 2025, including an elevator malfunction that left one of two elevators inoperable since December 19, 2024, problems with building security including a broken front door lock, and a significant plumbing incident involving flooding possibly related to an unpermitted dishwasher installation on the 8th floor. The building's mechanical systems have also shown persistent challenges, with multiple complaints about inadequate heating between 2019-2022 and a reported electrical wiring issue in 2024 involving exploded light bulbs in Unit 307.

The property has a documented history of fire safety concerns, with multiple violations recorded between 2016 and 2024 related to the alarm system, sprinkler system, and other life safety features. Recent violations from October-December 2024 include issues with the high-rise sprinkler system compliance schedule that, as of January 2025, remains open. The building has also experienced security and maintenance challenges, with complaints about blocked exits and common area maintenance. Historical records show the property was cited for illegal short-term rentals in 2017, which was subsequently resolved. While substantial unit improvements have been made, the building's infrastructure systems and recent maintenance issues suggest ongoing challenges that require monitoring.

Risk rating

How 645 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

Out of 448 buildings in this neighborhood, 296 are predicted to be safer.
