Augrented Insights Report

The three-story, 9-unit multi-family residential building at 846-850 Capp Street in San Francisco's Inner Mission neighborhood has undergone several significant improvements and faced various challenges since its construction in 1907. Most recently, in 2022, the building received kitchen and bath renovations in unit 850-A, including appliance updates and new fixtures, while also undergoing electrical improvements. Importantly, there are ongoing plans to convert the basement into additional residential units, with proposed work including non-structural modifications, bathroom additions, and installation of an NFPA 13 sprinkler system, potentially increasing the building's total units to 11. The building has a documented history of heating system issues, with multiple heating-related complaints between 2015-2019, though recent maintenance records suggest improvements.

The property successfully completed a mandatory soft-story retrofit in 2017, achieving compliance with seismic safety requirements. The building has experienced recurring issues with its alarm and fire safety systems, with multiple violations and corrective actions recorded between 2023-2024 regarding fire extinguishers, alarm system maintenance, and documentation requirements. Historical complaints from 2021-2022 noted problems with common area maintenance and lighting, though these issues appear to have been addressed. The property underwent significant infrastructure improvements in 2019, including a new roof and heating system upgrades.

Fire incidents have been minimal, with no civilian injuries reported, though system malfunctions and false alarms have been documented. The most recent routine inspection in October 2023 identified several violations related to gas utility shutoff tools and instructional diagrams, which are currently being addressed. Recent 311 calls in late 2024 have primarily concerned street cleaning and debris removal, suggesting ongoing challenges with exterior maintenance. The building's unit conversion project has received planning approval, subject to specific conditions regarding open space and window exposure requirements.
