629-631 40th Ave, San Francisco, CA 94121

The property at 629-631 40th Avenue in San Francisco's Outer Richmond district is a two-unit, two-story residential building constructed in 1981, currently owned by Wai Peter and Yuen Sin. The most significant recent maintenance work occurred in 2015, when both units underwent repairs including the removal and replacement of deteriorated wooden balconies and the conversion of sliding doors to windows on the second and third floors, with the project originally costing $3,000 but later adjusted to $8,000. The building has experienced recurring sewer issues, with documented backups in both May and October of 2020, though these were resolved through official work orders.

A tree-related concern was reported in September 2022 regarding damaged sidewalks due to lifted roots, and this issue remains open as of the last report. The property has generated several 311 calls, primarily related to parking issues, which are not uncommon in this neighborhood. These include two instances of driveway blocking (most recently in September 2024), abandoned vehicle complaints (July 2024), and various parking violations.

The building's immediate vicinity has experienced some maintenance challenges, including a general cleaning request for loose garbage in February 2023. In June 2012, there were fire safety inspections related to weeds, grass, and combustible materials, though these complaints were found to have no merit. While the building has encountered some maintenance issues over the years, particularly related to its sewer system and exterior features, there have been no recent fire safety concerns or serious building code violations on record.
