Initial analysis

2406 Polk Street is a 4-unit multi-family residential building located in San Francisco's Russian Hill neighborhood, owned by Leland Wong and Rosemary Lew. The 3-story structure, built in 1912, has undergone several significant modifications and improvements over the last few years. Most notably, in late 2019, the building transitioned from a retail use to a nail salon/service establishment, accompanied by ADA accessibility improvements including a new bathroom, front entry modifications, and associated electrical and plumbing work totaling approximately $20,000. Prior to this, in 2018, the building underwent reroofing work costing $16,000.

The property has experienced some maintenance issues over its history, with records showing past concerns including dry rot and water damage to the ground floor subfloor, though this permit from 1994 is marked as expired. More recently, there have been various 311 calls related to the property and its immediate vicinity between 2023-2024, including reports of graffiti, hazardous materials, construction noise, and street cleaning issues. Notably, there is currently an open case from November 2023 regarding graffiti on the building. The building has also undergone significant accessibility improvements under the ABE program, with permits showing work on hardware, public sidewalk repairs, and a bathroom addition. While the property has seen multiple improvements and renovations to maintain its functionality and comply with current standards, the recurring graffiti incidents and recent maintenance calls suggest ongoing challenges with property upkeep in some areas.

Risk rating

How 2406 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.
