Augrented Insights Report

The two-unit, two-story multi-family residential building at 5231-5233 Mission St in the Croker Amazon neighborhood, built in 1927, has experienced several concerning issues over recent years, with the most significant being an active complaint from May 2024 regarding unauthorized installation of a shower, kitchen, bedroom, and bathroom in the storefront area, along with unpermitted electrical and plumbing work, and a report of foul odors from the upstairs unit. The building's maintenance history shows various window replacements between 1984 and 2006, with the most recent upgrade occurring in 2006 when five existing wood frame windows were replaced with insulated double glass vinyl windows.

The property has a documented history of plumbing-related issues, including a serious leak affecting adjacent properties in 2018 and multiple complaints about sewer problems in 1998 and 2024. Recent maintenance concerns include a missing side sewer vent cover reported in May 2023 and recurring issues with graffiti, with multiple incidents reported between 2019 and 2023, though most have been resolved through official channels.

A complaint from December 2019 regarding unauthorized conversion of a salon to a residential unit and improper disposal of construction debris was filed but is marked as not active. The property appears to have been maintained through various repairs and upgrades over the years, though many improvements have been made under complaint-triggered circumstances rather than through regular maintenance channels.
