78 Mars St, San Francisco, CA 94114

The property at 78 Mars Street in Corona Heights is a two-unit, two-story multi-family residential building constructed in 1906, currently owned by the Stinson Weiss Family Living Trust. Over the past decades, the building has undergone several significant renovations and improvements, with the most recent major work occurring between 2020-2021, including a third-story interior remodel with kitchen and bathroom updates ($50,000), sewer lateral replacement, and associated plumbing and electrical work.

The building has seen consistent maintenance and upgrades, including multiple window replacements (most recently in 2018 with Marvin wood and Milgard fiberglass windows), kitchen and bathroom renovations (2003 and 2020), and infrastructure improvements such as a 200-amp electrical service upgrade and the installation of 12 rooftop solar panels in 2012. Historical records show some construction-related issues in 2001 regarding a retaining wall and deck work that prompted a building complaint, though this violation was abated in early 2002.

The property has maintained active compliance with permits and generally demonstrates regular upkeep. Recent 311 calls (2022-2024) have primarily related to external matters such as parking issues, sidewalk graffiti, and street maintenance, rather than building-specific concerns. The most recent building permits and improvements suggest ongoing investment in the property's maintenance and modernization, particularly focusing on interior spaces and energy efficiency features.
