3335-3339 Divisadero St, San Francisco, CA 94123

The three-unit residential building at 3335-3339 Divisadero Street in the Marina district, owned by Wahlberg Properties LLC, has undergone significant recent improvements since late 2022. The property, built in 1929 and classified as a Flats & Duplex, is currently undergoing comprehensive upgrades including a major electrical system overhaul with the installation of a 400-amp tri-meter panel system (completed October 2023), reroofing work (October 2023), and stucco application on exterior walls (November 2023).

A notable safety improvement was the installation of a new NFPA 13 fire sprinkler system and dedicated fire service line completed in early 2024, demonstrating commitment to modern safety standards. The building has undergone substantial renovations including HVAC relocation, window modifications, and plumbing upgrades throughout all three units. A building violation from November 2021, related to unauthorized interior work and foundation excavation, has since been resolved as of September 2023.

Multiple 311 calls regarding driveway blocking were recorded between late 2022 and 2024, though most were resolved without incident. The property has a completed planning record for seismic strengthening and unit remodeling, including a 399 sq ft addition and various window modifications, reflecting significant investment in both structural and aesthetic improvements. All recent permits indicate active maintenance and upgrading of building systems, with particular attention to fire safety, electrical infrastructure, and general building envelope improvements.
