41-43 Mars St, San Francisco, CA 94114

The property at 41-43 Mars Street in Corona Heights is a two-unit residential building constructed in 1890, currently owned by Emily Brooke Farmer. The building has undergone several significant renovations and improvements over the past decades, with the most recent work completed in early 2024 including a comprehensive bathroom remodel with new fixtures and tiles, electrical updates, and plumbing modifications.

Prior improvements include window replacements in 2022, deck repairs in 2016 (addressing dry rot issues), and an important underground electrical service conversion in 2006. The building's maintenance history shows attention to critical infrastructure, including roofing work in 2000 and earlier expansions such as bedroom additions and deck constructions in 1986. The property has experienced various maintenance and service issues that required attention, including a sewage backup in July 2023 and multiple parking-related incidents on and around the property between 2022-2024.

Of particular note, there was a confirmed violation regarding short-term rental activity, which was addressed and resolved in 2023 when the property owner was instructed to cease such activities to comply with residency requirements. The building appears to be actively maintained, with the most recent significant improvements focusing on modernizing fixtures and systems while addressing historical maintenance issues like deck and window repairs. The surrounding area has experienced ongoing parking challenges, as evidenced by multiple enforcement actions, though these are external to the building itself.
