Addison adopts unified development code; council increases allowable window signage and expands sidewalk signs for mixed-use areas

The Addison City Council on March 25 voted to adopt a new Unified Development Code that reorganizes the town’s zoning, subdivision, building and sign rules and sets a Sept. 1, 2025, effective date. Council members approved the 200‑plus page UDC after a public hearing and a month of additional edits, and instructed staff to modify the sign standards: increase the maximum window sign coverage and expand temporary sidewalk signs in select districts.
