Some plans refer to Development Lots or Secondary and Tertiary Lots. These are features of more complex and mixed use developments.
Development lots
A development lot is a lot that is intended to be divided into additional lots at a later date. Any development must be in accordance with the development contract, scheme description, and by-laws of the scheme.
Secondary and tertiary schemes
When a property has lots grouped together for different purposes (such as residential, retail or offices) then secondary or tertiary schemes may be created. The primary, secondary and tertiary corporations have their own meetings and functions but are also connected to each other. The secondary (and tertiary) corporations are also bound by the development contracts, scheme descriptions and by-laws of the primary (and secondary) corporations.
