Splitting a parcel (or combining and splitting multiple parcels) into 5 or less parcels is considered a minor lot split. Splitting a parcel (or combining and splitting multiple parcels) into more than 5 parcels is considered a subdivision and must be approved by the Maricopa County Board of Supervisors. For a specific determination if a proposed lot split is considered a minor lot split or a subdivision, contact the Arizona Department of Real Estate at:
100 N 15th Avenue Suite 201 Phoenix, AZ 85007
The Maricopa County Planning and Development Department does not review, approve or regulate minor lot splits. Minor lot splits are considered a civil matter between property owners.

New Deeds / Records
It's highly recommended to contact a surveyor, title company and/or real estate professional to complete a minor lot split. When creating a minor lot split, you will need to record new deeds with the new separate legal descriptions for each lot at the Maricopa County Recorder's Office at:
You may also request new tax parcel numbers (APNs) for the newly created lots. Please be aware that lots that are split must meet the zoning requirements for the zoning district in which they are located, including minimum lot area and minimum lot width. In addition, any existing buildings or structures on the lots must meet the allowed uses, minimum required building setbacks, maximum lot coverage and related zoning requirements.
