Division and Merger of Land Plots under the Code
If you are looking into "subdivision approval", start from the proper legal concept: the Spatial Planning, Architecture and Construction Code of Georgia regulates the division of construction land plots and the merger of construction plots through the norms of its development-regulation chapter — there is no separate "subdivision approval" procedure in the Code. This page describes those norms: when a plot may be divided or merged, which requirements apply and which document creates the legal basis.
The anchor point is that the basic basis of a plot's development regulation is the detailed development plan. On a plot located within the area of effect of that plan, construction is allowed in accordance with the plan, and the detailed development plan is the basic basis for issuing a construction permit. Other cases not covered by this rule are regulated by the respective norms of the Code and by the Basic Provisions.
