Initial analysis

The 4-story, 10-unit apartment building at 2400 Polk Street in Russian Hill, owned by New California Land Co, was constructed in 1911 and has undergone several significant improvements over the years. Most notably, the building completed mandatory soft-story seismic retrofits in 2018, which included both commercial and residential components, demonstrating compliance with San Francisco's earthquake safety requirements. The building's electrical systems received substantial upgrades in 2005, with a comprehensive rewiring project that included new sub-panels, circuits, and fixtures throughout all units. Recent maintenance and safety improvements included alarm system corrections in May 2024 and a commercial handicap accessibility improvement in 2018.

The building has experienced some challenges over the years, though most have been addressed. In 2004, there were multiple violations related to fire safety and lead paint concerns, including issues with egress obstruction and fire escape ladders, all of which were resolved by March 2005. A plumbing upgrade in 2014 included the installation of a closed-loop system for radiant heat convectors, and various unit improvements were implemented during 2014-2015, including bathroom and kitchen remodels. Recent activity in 2024 has included multiple 311 calls regarding the surrounding area, primarily related to street cleaning and parking issues, though none directly involving the building's structural or safety systems. The building's soft-story retrofit work has been classified as Tier 4, with all required improvements completed and a Certificate of Final Completion issued.

Risk rating

How 2400 Polk 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.
