638 45th Ave, San Francisco, CA 94121

The 5-unit apartment building at 638 45th Avenue in the Outer Richmond district, built in 1908 and owned by Nicholas A Kaskanlian since 2006, has experienced several significant maintenance and compliance issues over its recent history. Most notably, there is an active concern from 2016 regarding foundation damage and cracking reportedly caused by construction at a neighboring property (634 45th Avenue), which remains unresolved as of this date. The building has undergone multiple renovations, with the most recent substantial work completed in 2022 including a $22,000 kitchen and bathroom remodel in Apartment 1, which was initiated to comply with a notice of violation.

Prior to this, the property had several significant violations in 2000 that were eventually abated, including issues with mold/mildew, water damage, damaged walls, and various building code violations. The building has faced recurring maintenance challenges over the years, including stucco repair work in 2017 and 2021, and various plumbing and electrical updates. Several complaints about garbage management, including issues with containers being left out and attracting pests, were filed between 2010 and 2019.

More recent complaints in 2022-2023 have focused on sidewalk blocking and garbage disposal issues. The property underwent routine housing inspections in 2002 and 2006, with violations being documented and subsequently addressed. Recent maintenance activity shows ongoing attention to building upkeep, though several historical issues, such as the unresolved foundation concerns, remain notable. The building's permit history shows regular maintenance and improvement work, though there have been instances of unpermitted work that resulted in complaints, such as the 2021 incident involving unauthorized construction work.
