735-737 31st Ave, San Francisco, CA 94121

The two-story multi-family residential building at 735-737 31st Avenue in the Central Richmond neighborhood, owned by Xiao Yangping & Lu Congju, was constructed in 1939 and contains two units. The property has undergone several significant renovations and repairs over the years, with the most substantial work occurring in late 2015 when both units received major updates including kitchen and bathroom remodels, window replacements, and repairs to address water damage and dry rot issues, particularly at the rear stairway. This work, valued at approximately $40,000, was initially the subject of two complaints from neighbors in November and December 2015 regarding unpermitted construction activity, though these complaints were later addressed through proper permitting.

Earlier improvements include a 2005 renovation that added a bedroom, laundry room, storage room, and bathroom upgrades, along with electrical system improvements including a 200-amp service upgrade. The building's maintenance history shows attention to structural issues, with records from the 1980s indicating repairs for dry rot and stair maintenance. Recent activity at the property has primarily involved routine sidewalk and street maintenance issues, as indicated by multiple 311 calls between 2022-2024, including reports of abandoned vehicles, parking violations, and general cleaning needs.

A notable concern was filed in 2007 regarding an in-law unit with a full kitchen and bathroom, though this complaint was eventually abated in 2009. The most recent planning record from 2021 indicates a closed case for a proposed rear deck and landing addition requiring Variance and Building Approval. The building's documented history shows consistent maintenance and upgrading of both units, with particular attention paid to addressing structural and water-related issues when they arise.
