A. All homesteads shall be separately listed and assessed and separately described on the assessment rolls and tax rolls wherever possible. No homestead exemption shall be allowed on any improvements on real estate or other buildings which are used for business or commercial purposes, but where the same improvement or building is used both as a dwelling and for business purposes the value of that portion used as a dwelling shall be considered to be a part of the homestead and subject to exemption.

B. In any case where a building is used partially as a dwelling and partially for business or commercial purposes, or where some buildings on the same tract of land consist of the dwelling and appurtenances and others are used for business or commercial purposes, it shall be the duty of the county assessor to separately value the dwelling and appurtenances and that part used for business or commercial purposes. The keeping of boarders or roomers by citizens in a building maintained otherwise exclusively as a home shall not be considered as commercial purposes.

C. The location and use of a part of a building or buildings for business or commercial purposes on a rural homestead shall not prevent the owner of such homestead from obtaining an exemption on one hundred sixty (160) acres of land; but in case of urban homesteads where it is impossible to definitely separate by description, land upon which the dwelling and appurtenances are located, from the land upon which the business or commercial buildings are located, only that proportion of the land shall be considered a part of the homestead and subject to exemption which the proportion of the assessed value of the dwelling and appurtenances bears to the total assessed valuation of all buildings and improvements on such lot or lots.

D. In the case of rooming houses, duplexes, apartment buildings, or any other building occupied by more than one family, and used entirely for residential purposes, the homestead and part subject to exemption shall be considered only that proportion of the total assessed value of the land and improvements as the number of rooms occupied by the owner bears to the total number of rooms of such building. The renting of not to exceed three bedrooms shall not constitute business or commercial use or affect the exemption of a homestead and at no part of any hotel, motel, hostelry or apartment hotel shall be exempt.

E. In the case of rural homesteads, the homestead shall consist of not more than one hundred sixty (160) acres of land, which shall include and be about and contiguous or adjacent to the land upon which the dwelling house stands, to be selected by the owner, and the land designated as the homestead shall, as nearly as possible, consist of some legal subdivision of a section or sections.
