35-37 Norton St, San Francisco, CA 94112

The property at 35-37 Norton Street in Mission Terrace is a two-story, 3-unit multi-family residential building constructed in 1915, currently owned by Golden Properties LLC. The building has a significant history of unpermitted modifications and subsequent enforcement actions, most notably in 2018 when the city issued a notice regarding an unauthorized dwelling unit conversion, prompting the filing of permits to legalize the unauthorized modifications.

Earlier violations in 2010 documented the illegal conversion of a garage space into a separate dwelling unit, which was addressed through permits and completed work to remove unauthorized kitchen and bathroom facilities. The building has experienced persistent maintenance issues, including multiple reports of water leaks, mold, and ceiling damage between 2016 and 2018, with the most recent complaints indicating problems including insects, rodents, and possible structural concerns with a retaining wall. Recent activity at the property has primarily involved parking-related issues, with multiple reports of illegal parking and driveway blocking reported between November 2024 and January 2025.

There was also an incident involving sidewalk defects due to tree root uplift in November 2024. While the building has undergone various repairs and improvements over the years, including a kitchen remodel and window replacements in the 1980s, its history of unauthorized modifications and subsequent compliance efforts suggests ongoing challenges with maintaining proper building code compliance. The most recent active violation from 2018 indicates unresolved issues regarding unpermitted plumbing, electrical work, inadequate heating, and improper occupancy arrangements, particularly concerning the conversion of garage space into additional living units.
