Augrented Insights Report

The six-story apartment building at 634-644 Polk Street, owned by Casa Cw Llc, was constructed in 1928 and contains 32 units. The building has undergone several significant renovations and faced multiple safety compliance issues in recent years.

Most notably, in 2024, there were multiple fire safety violations related to standpipe systems and sleeping area requirements, with some violations still listed as open. Recent work includes a 2024 fire alarm system upgrade costing over $69,000, along with various retail space modifications and sign legalizations. In late 2023, Unit 503 experienced multiple maintenance issues including plumbing problems, electrical concerns, and pest infestations, though these were marked as resolved by April 2024.

The building has a history of fire safety incidents, primarily involving false alarms and occasional cooking-related events, though no civilian injuries have been reported. Between 2023 and 2025, there have been multiple 311 calls regarding garbage and debris management in the vicinity of the property. The building's maintenance history includes window replacements, bathroom and kitchen renovations in 2019, and electrical system upgrades, though there have been complaints about unpermitted work in 2024 that resulted in some ongoing compliance issues.
