CA-16 · Screened 2026-09-12 · Strong candidate
This building does not pencil on its own, but a modeled RESIDE Act grant closes the gap.
Every floor carries 2,049 sq ft of windowless core — area that must be gutted, seismically braced and sprinklered but can never be rented as an apartment. Across 5 residential floors that is 10,247 sq ft of cost carrying no revenue.
