197-199 Portola Dr, San Francisco, CA 94131

The property at 197-199 Portola Drive is a two-unit, two-story multi-family residential building located in Noe Valley, constructed in 1936 and currently owned by Michael Chieh Huang. The building has undergone several significant improvements over the years, with the most recent being the installation of a solar PV system in 2020-2021, consisting of 12 panels with a capacity of 4.08 kW and battery storage. In 2019, a substantial reroofing project was completed at a cost of $26,100.

The building has experienced multiple electrical system upgrades, including a complete rewiring in 2004-2006 with new service installation, and various safety improvements such as the removal of abandoned chimneys and wood fireplace. Several permits related to street space and sidewalk maintenance have been issued between 2005 and 2019. The building's history includes some fire department responses, though none resulted in significant damage or injuries - most were for false alarms, system malfunctions, and routine issues like cooking fires contained to containers.

Recent 311 calls from January 2025 primarily relate to public graffiti on nearby infrastructure, with some issues regarding traffic signs and litter receptacles, though these are external to the building itself. There have been no reported building code violations or safety concerns specific to the structure. In terms of proposed modifications, there have been applications for vertical and horizontal additions to the two-unit building, though these were either withdrawn or required additional approval processes, indicating they were not completed as originally planned.
