The former Horsham Fire Station is to be sold by West Sussex County Council.
The building, in Hurst Road, was declared surplus to requirements in 2020 and closed in 2023, with a new fire station opening in Macfarlane Way.
The decision to sell was approved by Jeremy Hunt, cabinet member for finance & property, on Friday (October 4).
While no information has been shared about how much the council will receive for the one-acre site, it has been advertised online with a guide price of £2.5million.
A report from Andrew Edwards, assistant director (property and assets), said nine bids for the site were received by the council.
Options other than selling were looked at, including whether the building could be used for social, community or environmental use, but none were considered viable.
