Combination, Lot Division, Boundary Line Adjustment

Combination/Lot Division/Boundary Line Adjustment

A property owner may seek approval to update their property through a lot division, combination or boundary line adjustment map change project.  A lot division/separation project regards splitting a single parcel into two (2) parcels.  A combination project regards merging two (2) or more parcels into one (1) single parcel. A boundary line adjustment project regards adjusting adjacent property boundary lines amongst two (2) or more parcels. 

1) DeKalb GIS requires that all parcels involved in the map change must have matching (verbatim) ownership.

2) DeKalb GIS requires that all re-parcel / boundary line adjustment map changes must display all owner name(s) on the coversheet as per DeKalb Tax Records.

3) All parcels must have the same tax district (cannot combine unincorporated parcels with parcels that are located in a municipality).

4) All parcels must have the same zoning conditions.

5) If the combination/lot division/boundary line adjustment project is within a municipality you must receive written permission from the municipality. A routing slip from any city or municipality (incorporated projects) must be included with the 1st initial submittal for all combinations, separations, re-parcels, subdivisions, townhomes, condominiums, &  Land Disturbance Permits (LDP).  

NOTE:  Any projects within the City of  Decatur, Atlanta, or Dunwoody must be submitted directly to the municipality for review and approval. 


6)  If the combination, separation, or re-parcel is within unincorporated DeKalb and it’s for commercial or residential properties, contact Land Development to undergo a review and to obtain written approval by Land Development. 


Once your project is approved/signed by DeKalb County or an Incorporated City and you are ready to submit your hard copy request for the map change, please note the following reminders:

  • Prior to any plats (incorporated or unincorporated) being recorded at DeKalb Superior Court all acknowledgement stamps and all approval signatures must be embedded on to plat.
  • After recording please forward your recorded/confirmed e-file to DeKalb County GIS Department to complete the approved mapping update.
  • Please submit AutoCAD file with your recorded efile  plat to DeKalb GIS. The digitized site plan is a geo-referenced electronic file (.dwg, .shp, .dxf or .dgn in State Plane GA West NAD 83 Coordinate US Survey Feet System.) Please submit this original digitized file with your recorded/confirmed e-file document to DeKalb GIS.
