Initial analysis

The 3-story multi-family residential building at 1729-1739 Polk Street in San Francisco's Nob Hill neighborhood, owned by Nguyen Venture LLC, was constructed in 1907 and contains 5 units. The property has undergone significant commercial transformation in recent years, now featuring a cannabis retail establishment and previously housing various food service businesses. Most recent improvements include the installation of multiple signs for "Sparc" dispensary in 2023 (cost: $8,000), and plumbing work including backflow preventer installation in 2023. A substantial renovation occurred in 2021, involving the replacement of furnishings, installation of new fixtures, and various interior improvements (cost: $75,000). The building has a complete soft-story retrofit status as Tier 3, indicating compliance with seismic safety requirements.

Historical records show multiple building violations from 2006 that were resolved, primarily related to maintenance issues such as fire extinguisher inspections, common area cleanliness, and interior surface repairs. The property has experienced several routine safety inspections and complaints over the years, with the most recent being a public health complaint filed in January 2025. There were instances of unauthorized work reported in 2014-2019, but these complaints were ultimately resolved. The building's infrastructure has been maintained through various permits, including electrical upgrades, fire protection system improvements, and plumbing work between 2003-2023, demonstrating ongoing maintenance and compliance with regulatory requirements. Recent 311 calls from late 2024 primarily relate to street cleaning and maintenance issues outside the building, rather than internal building problems.

Risk rating

How 1729-1739 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.

Neighborhood percentile

Out of 1125 buildings in this neighborhood, 518 are predicted to be safer.
