The Pima County Board of Supervisors decided Tuesday to spend about $530,000 to redesign three floors of the new county courthouse downtown.

County Administrator Chuck Huckelberry said the money will pay to change those floors from previously planned city court space, to office space for the county assessor, treasurer and recorder.

The city of Tucson pulled out of plans to use three floors of the new courthouse after the city and the county disagreed on the city's financial share of the project.

The board unanimously approved the additional spending from the county budget, but Supervisors Sharon Bronson and Ally Miller said they want to know the total cost of the new courthouse. Huckelberry said he will provide that number.

He said the half million dollars for the three floors does not include furniture or equipment needed before the county assessor, treasurer and recorder can move into those floors.
