In early 2006, KOOP's 304 E. Fifth Street studio was hit by two fires. On 6 January a fire caused significant smoke damage; the station suspended operation for just five days and sought a new home. Before a site could be found, a second fire occurred on 4 February which destroyed KOOP's building and three adjacent structures that housed artist studios and a nightclub. Both fires were declared accidental. The first was blamed on careless smoking by a neighbor; the second, on the nightclub's faulty heating and air conditioning unit.
