Unfortunately address assignment is derived from county building permits except in very special situations. Technically counties issue "situses" and the USPS adopts those as delivery addresses. Most/all counties won't hand out a situs without a building permit and completed inspection. USPS can create addresses without county situses (for example, military installations or federal hydroelectric projects) but I don't think they will do it in any situation that's applicable here.
