What this means

The commission approved a plan to replace six industrial office buildings with 329 new homes at 510 and 920 De Guigne Drive. The project includes 41 accessory dwelling units, which are smaller homes on the same property, and requires a homeowners association for the condominium portion. Commissioners said the project would add needed housing, but public comments raised concerns about traffic, parking, walkability, noise, dust, and the lack of retail space. The decision can still be appealed or reviewed by the City Council by March 10, 2026.
