The Town of Addison Board of Zoning Adjustments unanimously approved a variance to allow a 27,000-square-foot aircraft hangar at 15500 Wright Brothers Drive to encroach into the 25-foot side-yard setback, reducing the setback to 3 feet. Staff recommended approval citing the roadsegment's limited use and existing site conditions; the applicant said the variance is necessary to build the proposed hangar.
