A lot split is a type of survey used to subdivide an existing parcel of land into multiple parcels while a consolidation survey is used to combine multiple parcels of land into one parcel. Each county, township, or municipality may have different or additional regulations that need to be observed. Aside from relying on your Professional Surveyor it is suggested that property owners check with their respective county, township, and/or municipality to ensure that all guidelines for the proposed lot split or consolidation survey are able to be met.
