3366 Pierce St, San Francisco, CA 94123

The 12-unit, 3-story multi-family residential building at 3366 Pierce Street in the Marina district was constructed in 1927 and is currently owned by Gruham LLC. The building has undergone several significant safety and infrastructure upgrades in recent years. Most notably, it completed a mandatory soft story seismic retrofit in 2017 (Tier 3) at a cost of $110,000, followed by low-frequency sounder installations and fire alarm system upgrades in 2021/2022 to enhance fire safety.

Other major improvements include a staircase replacement for emergency egress in 2015 ($16,000), a comprehensive window replacement project in 2008 ($39,500), and an electrical service upgrade in 2004. The building's maintenance history shows attention to safety compliance, with previous violations in 2001-2007 related to boiler permits and fire extinguisher maintenance that were all properly resolved. There have been two smoke detector activations with no fires recorded in the fire incident history.

Recent 311 calls primarily relate to parking enforcement issues, with multiple reports of blocked driveways between 2021 and 2025, as well as some incidents of sidewalk cleaning needs in 2021. A fire complaint regarding blocked exits in 2020 was found to have "No Merit," and a staircase replacement project was completed to address egress requirements. The building appears to have maintained compliance with safety regulations, particularly through its recent seismic retrofitting and fire safety system upgrades.
