Initial analysis

The 12-unit multi-family residential building at 1738-1742 Polk Street, currently owned by Devpac LLC, is a three-story structure built in 1909 located in San Francisco's Nob Hill neighborhood. The building has undergone significant recent renovations, with major updates in units #1 and #8 completed in 2023-2024, including kitchen and bathroom remodeling, window replacements, and furnace system installations. The property has a completed soft-story retrofit and ADA improvements from 2021, along with a mandatory fire alarm system upgrade completed in 2022 to comply with California state requirements. Recent plumbing and electrical work in early 2024 included furnace installation and renovation work in unit #8.

Historically, the building faced some challenges, including multiple building violations in 2016-2019 related to mold/mildew issues, a vacant storefront complaint, and several fire alarm system-related incidents between 2009-2017. During 2020, there were complaints about construction work allegedly violating COVID-19 restrictions, and the property was involved in a vacant storefront registration issue. The ground floor underwent a change of use in 2021 from retail to a hair salon (d.b.a. RRRSalon). Recent 311 calls from 2024 have primarily concerned noise complaints related to entertainment, with multiple violations issued for operating with doors and windows open. The building's systems have generally been well-maintained, with prompt responses to fire complaints and a completed fire alarm system upgrade indicating attention to safety requirements.

Risk rating

How 1738-1742 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.
