Augrented Insights Report

The three-story, ten-unit multi-family residential building at 1020 Potrero Avenue, owned by the Harty Living Trust, has a complex maintenance history dating back to its 1949 construction. Most recently, in October 2023, the building received two violations related to fire safety requirements: one for not providing date tags for fire extinguishers and another for non-compliance with fire safety affidavit requirements. The building has experienced several significant maintenance issues over the years, with the most serious occurring in late 2021 when multiple violations were documented regarding water damage, mold, ceiling repairs, and pest infestation, though these were all officially abated by March 2022.

The property underwent a fire alarm upgrade in 2020 to comply with SFFC requirements, and windows in apartment #4 were replaced in 2022 to address a notice of violation. The building's maintenance record shows recurring plumbing and water-related issues, including dry rot repairs in 1998, plumbing work in 2021 for a new shower drain and pan installation, and multiple fire safety system inspections. Historical complaints from the 1990s indicate more severe problems, including ceiling damage and heating issues in 1994-1995.

Recent 311 calls in 2024 have primarily concerned external issues such as graffiti and a collapsed sidewalk, though there are still some open cases regarding building maintenance. Fire incident records show primarily false alarms and system activations, with no civilian injuries recorded from any incidents. The building's inspection history includes regular routine inspections by Housing Inspection Services, with varying degrees of maintenance compliance noted over the years.
