Initial analysis

The property at 50-52 Turk Street is a 7-story, 42-unit multi-family residential building constructed in 1914, currently owned by Natverbhai N Patel. The building has undergone numerous maintenance and safety-related improvements over the past decade, with the most significant recent work being a comprehensive fire system replacement in May 2024, including new panels, smoke detectors, and horn strobes throughout the building. However, the property has faced recurring fire safety and building maintenance challenges, with multiple open fire violations as of October 2024 related to alarm systems, sleeping area requirements, standpipe maintenance, door functionality, and exit visibility. Recent complaints from 2023-2024 indicate ongoing concerns with building systems, including elevator functionality, water damage, and mold. Multiple fire complaints in 2024 regarding alarm systems, blocked exits, and sprinkler systems resulted in violations being issued, highlighting continuing concerns with fire safety systems. The elevator has been a recurring issue, with documented failures in late 2019 significantly impacting disabled and senior residents. The building has also undergone substantial plumbing upgrades, including the installation of new water heaters and boilers between 2015-2018, and electrical improvements including hallway lighting upgrades.

The property has a history of responding to housing code violations and complaints, with regular maintenance work completed in response to various building inspections. Notable recent complaints include issues with hazardous appliances, structural problems, and pest control in 2021, as well as documented plumbing issues in multiple units. The building's fire incident history shows several alarms and system malfunctions, though no civilian injuries have been reported. While many historical violations have been resolved, multiple open violations as of 2024 suggest ongoing compliance challenges. The property has also experienced routine infrastructure issues common to older buildings, including water damage, elevator problems, and ventilation concerns. Regular maintenance and system upgrades, including the recent comprehensive fire system replacement, demonstrate ongoing investments in building safety and habitability, though recurring safety violations indicate areas requiring continued attention.

Risk rating

How 50-52 Turk 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.
