All plat or deeds that change property lines must first be reviewed by department staff before it is recorded to verify that it meets the requirements of County codes and State Statutes, specifically the Illinois Plat Act. If your property is in a City or Village, check with their panning staff before trying to record your documents. The Rock Island County Recorders Office has provided a document with requirements for recording subdivision plats.
Types of Plats
Preliminary Plat - A preliminary plat is a proposal to legally subdivide a parcel of land into separate lots, each properly designed for a certain type of development. A preliminary plat acts as an agreement between the County and the subdivider as to the development’s layout. Specific subdivision considerations include lot size, open space, density, street layout, access, floodplains, utilities, easements, and public improvements.
Final Plat - A final plat legally establishes the division of property into separate parcels or tracts. A final plat shows lot boundaries, street dedications, easements, and any other divisions of land. Final plats must be prepared by a registered surveyor or engineer and must include all requirements outlined in the ordinance. A final plat must be submitted within 1 year of the approval of the preliminary plat and substantially conform to the preliminary plat.
