Initial analysis

1870 Pacific Avenue is a 6-story, 30-unit multi-family residential building constructed in 1937, currently owned by LSL Properties B14 De LLC. The building has undergone significant renovations in recent years, with multiple units receiving kitchen and bathroom remodels between 2020-2024, including the most recent work in Unit 401 as of October 2024. However, there are concerning current issues: as of late 2024, residents have reported inadequate heating (with temperatures between 60-66 degrees) and September 2024 saw an elevator outage impacting accessibility. The building's safety systems have faced ongoing scrutiny, with multiple fire safety violations issued in 2023-2024 regarding alarm systems and sprinkler systems, though many have been corrected. Historical problems from 2001-2009 included various maintenance and safety issues such as plumbing problems, water damage, and fire safety concerns, though these were all abated by November 2009.

Recent complaints highlight persistent accessibility challenges, particularly for disabled residents, due to the building's entrance configuration and elevator reliability. Windows have been a recurring issue, with multiple complaints between 2018-2019 regarding ventilation, air sealing, and safety compliance. The property has experienced several fire alarm activations and elevator rescues, though fortunately none involved civilian injuries. Multiple zoning verification letters have been issued for the property, confirming compliance with planning code section 140 for exposure. While many units have been modernized and the property has addressed numerous historical violations, the recurring nature of heating, elevator, and fire safety issues suggests ongoing maintenance and systems challenges within the building.

Risk rating

How 1870 Pacific Ave'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.
