521-523 Velasco Ave, San Francisco, CA 94134

The two-unit residential building at 521-523 Velasco Avenue in Visitacion Valley, owned by Maria E Silva, is a two-story flats and duplex structure built in 1948.

The property's most significant incident on record occurred in August 2004, when a fire prompted extensive repairs costing $45,000, including work on sheetrock, cabinets, insulation, and roof repairs at the top floor, addressing smoke and water damage. This fire-related work also necessitated electrical upgrades, initially documented under permit #E200408316963 for the installation of 7 lights, 7 switches, and 16 receptacles, though this permit expired and required subsequent processing through permit #E20050907379 in September 2005, which has since been completed.

The building's recent history shows no major structural or safety concerns, with only one 311 call recorded - regarding an abandoned vehicle on the street in October 2017, which was resolved when the vehicle had left the location by November 3, 2017. The property appears to have maintained regulatory compliance following the fire repairs and electrical work, with no further permits or violations of note in the available records up to October 2023.
