The property's exterior has faced some quality of life challenges, including a 2021 incident of offensive graffiti that required intervention from PG&E. A pattern of parking violations near the property is evident, with multiple 311 calls between 2018 and 2024 regarding vehicles parking on sidewalks or blocking driveways, though these are primarily external neighborhood issues rather than direct building concerns.
