Initial analysis

2355 Polk Street is a six-story, 38-unit multi-family residential building constructed in 1924, currently owned by Sf Multifamily V Property O. The property has undergone significant renovations over recent years, with multiple unit upgrades completed between 2018 and 2022, including comprehensive modernizations in units 401, 402, 201, 501, 603, and 306, featuring new kitchens, bathrooms, appliances, and lighting systems. In late 2020, there was a major proposal to add five new basement-level units within the existing envelope, though this permit is currently listed as "On Hold." The building has faced several concerning issues in recent years, particularly regarding elevator service, with multiple complaints and violations recorded in 2023 showing extended periods of non-functionality, though these were eventually addressed by April 2023.

The property has also experienced recurring fire safety issues, with recent violations including problems with the alarm system (2023), sleeping area requirements (2023), and sprinkler systems (2024). A notable tenant complaint from 2024 alleges an illegally converted bedroom in unit 103, though this is currently listed as "Not Active." Historical records show some past maintenance concerns, including a 2019 situation with potentially hazardous fumes in unit 305 during renovation, and a 2005 violation regarding boiler operation permits. The building's infrastructure has been regularly updated, including a new fire alarm system upgrade filed in November 2023 and previous work on fire sprinkler devices and hot water boiler systems in 2017 and 2011, respectively. Recent 311 calls from late 2024 to early 2025 indicate ongoing issues with garbage collection and street cleaning around the property, though these are municipal service matters rather than building-specific concerns.

Risk rating

How 2355 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
