3519-3521 Pierce St, San Francisco, CA 94123

The two-unit residential building at 3519-3521 Pierce Street in the Marina neighborhood is a two-story flats and duplex structure built in 1924, currently owned by Frank Giovannoni. The most significant recent improvement to the property was a comprehensive kitchen remodeling project completed in 2018, which included electrical upgrades (installing new lighting, switches, receptacles, and kitchen appliances), plumbing work, and cosmetic updates such as cabinet and floor renovations, all carried out with proper permits at a cost of $20,000.

In the building's more distant history, there was an attempt to reinforce the foundation in 1990, though records indicate this permit ultimately expired without completion. The property's 311 call history reveals several community-related incidents between 2012 and 2020, though none appear to directly relate to building safety or habitability concerns.

These incidents include two street cleaning requests in 2013 for loose garbage, a building-related complaint regarding illegal guest room conversions in 2019 (which was administratively closed), and a 2020 complaint about construction-related street maintenance issues involving construction plates and uneven ground, which was resolved. Two environmental health-related service requests were made in 2018 and 2012, though these were transferred to the Healthy Housing & Vector Control Program for follow-up. The building's permit and complaint history suggests regular maintenance and improvements have been undertaken, with particular attention paid to kitchen modernization as the most recent upgrade.
