When a developer is proposing a layout or subdivision of land into plots for residential, commercial or mixed use, where the land lies in the DTCP-jurisdiction and is subject to the Act’s control.
When the land in question falls under an area for which a master plan / new town development plan is in force, and development permissions must conform to the plan.
Why is it important?
To ensure legal compliance: development using land and buildings must conform to the planning norms and zoning as per the Act.
To avoid illegal layouts/plots, which may lead to enforcement action (including demolition) under the Act (e.g., Section 56 gives power to remove unauthorized development)
Residential plotted developments (plots for houses) in areas under DTCP jurisdiction.
Mixed-use layouts (residential + commercial) where subdivision of land is proposed.
The layout can be declared unauthorized under the Act, making plot transfers/registrations risky.
Legal action can be taken by the planning authority: demolition or stop-work orders.
