Often, voluntary mergers are processed in order to accommodate building setbacks, such as when buildings are constructed over lot lines. They are also processed to simply create larger parcels.

No, a voluntary merger does not affect easements, streets, dedications, offers of dedication, or any other recorded interests.

Voluntary mergers can typically be processed within 90 days of the application being deemed complete.
