Part Lot Control Exemption Application Process

Before starting a part lot control exemption application, all applicants should understand the requirements.

Confirm that you need this application

Part lot control is a provision of the Planning Act that, as the term implies, regulates the transfer or sale of part of a lot within a registered plan of subdivision. 

The municipality uses this provision as a means of preventing the possible uncontrolled division of lots within a plan of subdivision after the plan has been registered. Exemption from part lot control is commonly used to facilitate semi-detached and town-house developments. 

This approach is used because of the difficulty the builder would have in ensuring that the common centre wall between two dwelling units was constructed exactly on the property line. 

A Part Lot Control Exemption requires the owner of a property to apply to exempt all or parts of a registered plan of subdivision from part lot control to permit the conveyance of portions of lots or blocks.
