Areas annexed to the city shall be classified in the same zone as the land was classified immediately prior to annexation. If such zone does not exist in this chapter, the Planning Commission shall be authorized to determine the nearest comparable zone, and the land shall be zoned in said nearest comparable zone. The official zoning map shall be amended to indicate the zoning immediately upon annexation to the city. This section shall not be construed to limit the authority of the city to rezone areas annexed to the city, nor shall it be construed to limit the right of any property owner to request rezoning of properties being annexed to the city.
