The two-unit multi-family residential building at 649-651 Guerrero Street, located in Mission Dolores and owned by Barbara & Mark Allen Tr, is a two-story structure built in 1908. The property has undergone several significant improvements over the past decade, with the most recent major upgrade being the installation of a solar PV system in March 2014, consisting of 12 roof-mounted panels with a total rating of 2.73 kW.

Prior improvements include substantial structural reinforcement work in 2012-2013, such as foundation improvements (including to the laundry room extension), garage upgrades (footing, walls, and girder improvements), and a second-floor bathroom remodel with new fixtures and washer/dryer hookups. Window replacements were completed in 2011, addressing rot issues, and two furnaces were replaced in late 2011 with new energy-efficient units. The property has experienced recurring parking enforcement issues, with multiple citations for driveway blocking between 2021 and 2024, though several incidents resulted in officers being unable to locate the offending vehicles.

The most recent parking enforcement cases occurred in 2023-2024, with at least one citation being issued. On the public works front, there is currently an open case from May 2021 regarding a curb or curb ramp defect, and a service request was made to DPW in October 2021. The building's maintenance record shows regular upkeep and improvements to various systems, including electrical, plumbing, and structural elements, with all documented permits showing completed status.
