Initial analysis

171 Liberty Street is a 12-unit, 3-story multi-family residential building constructed in 1929, currently owned by Peter E Kardum 2006 Revoc L. The building has undergone various maintenance and improvement work over the years, including major systems upgrades such as the installation of an 80-gallon storage tank (2018), steam boiler replacement (2012), and most recently, a 240V heater installation (2023). The property has a documented history of plumbing issues, with multiple complaints regarding water leaks and heating problems between 2022-2024, including concerns about shower pressure, hot water consistency, and waste from a malfunctioning faucet in 2023. There were also notable violations related to heating systems in 2001 and 2017, requiring the installation of a non-tamperable temperature-sensing device and improved heating controls.

The building's safety features have been a concern, with multiple fire-related violations recorded in 2006, including issues with fire escape obstruction, improper door hardware, and combustible materials stored inappropriately. More recent fire complaints include a sprinkler/standpipe systems issue (2024) which was found to have no merit, and a violation related to alarm systems (2016). Recent tenant complaints in 2023-2024 suggest ongoing maintenance and communication issues between management and residents, particularly regarding urgent repairs and proper notification procedures for unit access. The building has seen various structural improvements over the years, such as window replacements and roof work, and underwent a service change from overhead to underground utility lines in 2003. Regular building inspections and 311 calls indicate ongoing attention to various maintenance issues, though many historical violations have been resolved.

Risk rating

How 171 Liberty 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.
