1511 Masonic Ave, San Francisco, CA 94117

The property at 1511 Masonic Ave is a three-story, two-unit multi-family residential building constructed in 1900, currently owned by the Coyne 2017 Living Trust. The building has undergone several significant modifications over its history, with the most substantial work occurring in the late 1990s, including multiple horizontal additions and the installation of a fire sprinkler system in the garage. Notable construction-related issues were addressed during this period, including exploration for dry rot at the rear deck and removal of wood lath and plaster throughout the three-story structure.

A legalization permit was successfully completed in 1992 to address prior unauthorized modifications. Recent records from 2023-2024 indicate recurring issues with parking violations near the property, particularly involving one vehicle (a white Range Rover) that was reported for sidewalk parking on multiple occasions between February and December 2024, with one case resulting in a citation. The building has experienced some maintenance challenges in the past year, with multiple graffiti incidents reported on the property in 2024, though most were resolved without action.

There is currently an open issue from September 2024 regarding property damage potentially involving urban forestry. The building's systems appear to be generally functioning normally, with only one recorded fire-related incident - a smoke detector activation due to malfunction - with no civilian injuries reported. The property's historical permit record shows comprehensive documentation of past modifications and maintenance work, though many of the permits from the 1990s are now expired.
