The Building at 826 North Main Street, at 826 N. Main St. in Cottonwood, Arizona, was built in 1925. It is a 25-by-75-foot building built of cast block and is significant of an example of better fire protection in construction following a 1925 fire in Cottonwood's business district. This building is reported to be one of only three examples of using cast block in particular, in Cottonwood, and "the only example of its use for residential purposes", although the building has in fact been used since for commercial purposes.
