Horton Plaza Repositioning
Central Downtown San Diego, adjoining Horton Plaza Park and the Gaslamp Quarter
The former shopping mall's office-and-commercial conversion passed to its lender through foreclosure in August 2025. July 2026 reporting identifies concrete park, theater-access and permitting work, but does not establish that the whole campus has reopened.[5][6]

From retail mall to mixed-use campus
Horton Plaza's multi-level, open-air retail layout was the starting point for a large downtown conversion. AMSI describes changing retail demand and a proposed mix of offices, shops, dining and flexible commercial or community uses near transit, housing and hotels.[20]
Bisnow reports that Stockdale's conversion plan called for 700,000 square feet of office space for technology and life-science tenants, plus 300,000 square feet for restaurants, retail and entertainment. These are historical plans, not evidence that those spaces are occupied today.[5]

Ownership and the 2026 work program
Bisnow reviewed a trustee's deed recorded August 26, 2025 and reported AllianceBernstein's $130 million credit bid following an auction with no other bidders. The Union-Tribune subsequently identified Horton Plaza Propco LLC as the lender's ownership vehicle for the campus and park leasehold.[5][6]
On July 1, 2026, the Union-Tribune reported that a May 18 City letter gave Propco 360 days to cure park-lease defaults, including $5 million in improvements followed by reopening. Propco also described priorities for Lyceum Theatre access and a temporary certificate of occupancy.[6]
Documents reviewed by the newspaper described the campus as 90%–95% complete, with major permits expired and construction completion delayed until mid-2027. This is a reported estimate, not a verified opening date. The source article's March statement that the future was wholly undecided is therefore incomplete when read against the later, specific work program.[6][20]
