2335-2337 North Point St, San Francisco, CA 94123

The two-unit residential building at 2335-2337 North Point Street in San Francisco's Marina neighborhood, owned by Eugene & Theresa De Mattei, was constructed in 1928 as a two-story flats and duplex structure. The property is currently undergoing significant modifications, with the most substantial being the installation of a 672-square-foot accessory dwelling unit (ADU) in the rear ground floor area, a project valued at $194,000 that began in August 2023 and continues to the present.

This ADU installation is accompanied by substantial infrastructure upgrades, including the replacement of existing water heating systems with high-efficiency tankless water heaters, a new radiant floor heating system, and comprehensive electrical work including 45 circuits and three panels replacing fuses (2024). Notably, there were two building complaints filed in late 2022 regarding illegal units, expired permits, and unpermitted work, with one complaint remaining active as of October 2023 concerning potential structural issues including foundation concerns. The building's recent history shows a focused effort to modernize and expand the property, with plumbing permits showing the addition of a second bathroom, kitchen, and laundry facilities (2024), and revisions to permit requirements including removal of certain testing requirements (2024).

The property's maintenance history includes a complete re-roofing project from 1988, and while some permits have been marked as expired, such as a 2022 boiler replacement permit, these appear to be addressed in subsequent work. The building has experienced recurring parking-related issues in the vicinity, with multiple 311 calls regarding vehicles blocking driveways and parking on sidewalks between 2019-2022, though these are external to the building itself. The current construction and improvement projects suggest active investment in upgrading the property, though the past building complaints regarding unauthorized modifications and potential structural issues may warrant attention.
