The minimum size of a parcel is the smallest lot you can create on a property. It is an important consideration for subdivisions and lot line adjustments. The zone classification determines minimum parcel sizes.
Generally, the zoning ordinance allows development to occur on parcels that don't meet the minimum parcel size as if they met the minimum parcel size. However, health and safety requirements other than the zone classification still apply. For example, onsite sewage disposal requires minimum parcel sizes that may differ from the zoning ordinance.
The City's Website shows parcels and zoning boundaries, which can be used to determine the zoning for your property.
Minimum parcel size and zoning classifications are described in the Kerman Municipal Code.
