In counties where there is no armory belonging to or under control of state authority, the county courts or boards of county commissioners, upon written application of the commander or president of any organized unit of war veterans or its auxiliary, shall allow its unit organized in such county, free of cost, to occupy a portion of the courthouse or any other public building, when such occupancy does not materially interfere with occupancy of the building for the original purposes for which it was intended.
