Also known as Approved plan
Before construction begins, the owner or developer submits drawings to the planning authority. Once approved, they become the sanctioned plan, and the commencement certificate is issued. Any later change in floors, units or use needs a revised sanction.
Buyers check the sanctioned plan to confirm that their unit exists in the approved drawing, that the floor they are buying is approved (not a floor added later), and that the open space, parking and amenities promised are on the plan. For registered projects, the sanctioned plan and any revisions are uploaded on the state RERA website.
Deviations from the sanctioned plan can lead to penalties, refusal of the completion certificate or, in serious cases, demolition orders.
Example
A builder in Jaipur offers a fifth-floor 3 BHK at ₹72 lakh. The broker checks the sanctioned plan on the Rajasthan RERA project page and finds approval for only four floors plus stilt parking. The developer says a revision is pending; the buyer decides to wait for the revised sanction before booking.
Figures are illustrative, not market rates.
Questions about Sanctioned building plan
How can I check if a building plan is sanctioned?
For a RERA-registered project, open the project page on the state RERA portal, where sanctioned plans and revisions are uploaded. Otherwise ask the developer for the approval letter and plan, and verify it with the municipal corporation or development authority.
Can a developer change the sanctioned plan after booking?
Section 14(2) of the RERA Act requires the allottee’s consent for changes to their own unit’s plan, and the written consent of at least two-thirds of the allottees for other changes to the building’s sanctioned plans, beyond minor additions or alterations. Buyers should read the agreement and the project’s revision history.
