2455 Jackson St, San Francisco, CA 94115

The four-story apartment building at 2455 Jackson St in Pacific Heights, built in 1900, is a 5-unit multi-family residential property currently under ownership of the Nancy E. Ryti Spousal Irrevocable Trust. The building's recent history is marked by significant structural and safety concerns, particularly regarding unauthorized construction work. In 2018, multiple complaints were filed about unauthorized roof work, resulting in Notice of Violations (NOVs) and subsequent investigations revealing unpermitted roof reframing, skylights, and deck modifications. This issue remains a significant concern, with recent complaints in 2024 about debris and damaged neighboring property.

The building underwent mandatory soft-story retrofit work in 2014 (classified as Tier 3, with work completed and CFC issued), and several seismic retrofit attempts between 2015-2018, though there have been compliance issues as indicated by multiple filed permits and expired permits between 2018-2019. The property has faced recurring issues with vacancy, as evidenced by multiple "vacant building" complaints between 2020-2024, and recent fire safety violations. In September 2024, violations were noted regarding blocked exits and storage in pathways, though these were subsequently corrected. Historical records show a pattern of maintenance and safety concerns, including earlier fire code violations in 2006 related to combustible materials and blocked exits. Infrastructure improvements documented in permits show efforts to address various building systems, including plumbing work in 2010-2011, electrical upgrades in 2004-2005, and multiple roof and interior repairs.

The property has also experienced periodic issues with neighboring buildings, particularly concerning debris management and safety concerns during construction work, with some incidents resulting in damage to adjacent properties. Parking enforcement records from late 2024 show recurring issues with blocked driveways near the property, suggesting ongoing access challenges in the vicinity. The building's current status shows active concerns regarding unauthorized modifications and compliance with safety requirements. Recent complaints about vacant status and safety violations suggest ongoing management challenges. Historical records indicate a long-term pattern of maintenance and compliance issues, though there have been some completed safety upgrades such as the mandatory soft-story retrofit. The property has undergone various structural modifications and retrofits in response to building codes, though compliance has been inconsistent as evidenced by numerous permits required for follow-up work and corrections.
