254 12th Ave, San Francisco, CA 94118

The property at 254 12th Avenue in San Francisco's Inner Richmond district is a two-unit, two-story multi-family residential building constructed in 1906, currently owned by Jeffrey Lonsdale and Sao Tran. The building has undergone substantial renovations and maintenance work over the past two decades, with the most recent work involving a complete roofing project in March 2024 costing $26,000.

Between 2019 and 2020, significant improvements were made including the addition of bedrooms, bathrooms, and skylights, particularly focusing on the third floor. Earlier renovations included foundation repairs and various plumbing and electrical upgrades in 2007-2009, with improvements to both units being documented.

A notable concern arose in July 2022 when a complaint was filed regarding an alleged unauthorized conversion of the duplex into a single-family home, though this complaint was later marked as "Not Active." The property has maintained regular upkeep through various permits and inspections, with most recent electrical and plumbing work being properly completed in 2019. Two tenant buyouts have been recorded, one in 2017 for $32,500 and a more recent one in September 2024 for $17,450, suggesting either unit consolidation or strategic property management decisions by the owners. The building's service history also indicates regular maintenance of public infrastructure around the property, though these are primarily routine city services unrelated to the building's condition.
