RERA Modification and Change Services – Amending Project Plans After Registration

Q: Can a promoter change the project plan after RERA registration?

Minor apartment-level changes need individual allottee consent. Significant changes to sanctioned plans affecting multiple buyers require written consent of two-thirds of allottees of the affected building under Section 14(2).

Q: What is considered a significant alteration under Section 14 of RERA?

Structural changes, additional floors, common area redesign, unit mix changes, carpet area revisions, and elevation changes are generally considered significant alterations requiring two-thirds allottee consent.

Q: What is the carpet area definition under RERA?

Under Section 2(k), carpet area is the net usable floor area excluding external walls, service shafts, exclusive balcony/veranda/terrace — but including internal partition walls. This definition is mandatory in all Agreements to Sale.

Q: How is a change in carpet area handled under RERA?

Changes up to 3% are typically handled by pro-rata price adjustment without fresh consent. Changes beyond the threshold require individual allottee written consent as per applicable state RERA provisions.

Q: Does RERA modification apply to commercial projects?

Yes. Section 14 applies equally to all registered projects. Commercial project promoters must comply with the same consent and disclosure requirements for significant post-registration plan changes.

Expert Advisory and Filing Support for Post-Registration Amendments to RERA Project Plans, Layouts, and Carpet Areas

Once a real estate project is registered under RERA, the promoter is bound by the registered project details — including the sanctioned building plan, approved layout, carpet area of each apartment, project specifications, and completion timeline. Section 14 of the RERA Act restricts the promoter's ability to make changes after registration: minor additions or alterations within an individual apartment may be made with the written consent of the individual allottee; however, significant changes to the sanctioned plans or project specifications affecting multiple allottees require the written consent of at least two-thirds of the allottees of that building or wing.

Managing post-registration modifications correctly is critical — unapproved changes expose the promoter to complaints, penalty orders, and RERA authority enforcement action. Our RERA modification services assist developer clients in assessing whether a planned change triggers the two-thirds consent requirement, obtaining and documenting the required consents, filing portal amendments, and maintaining an audit trail of all approved modifications. This service connects with our quarterly update and project extension compliance services.

Why Managing RERA Modifications Correctly Is Essential

Unapproved significant modifications are a RERA Act violation — buyers can file complaints and seek restoration plus compensation for unauthorised layout or specification changes
Correct consent documentation protects the promoter — a properly documented two-thirds consent is a defence against buyer complaints challenging the modification
RERA portal disclosure of modifications ensures transparency — buyers checking the portal can see all approved changes to the original registered plan
Modification amendments must be reflected in revised Agreements to Sale — updated agreements avoid contractual disputes on possession
Carpet area changes with allottee consent must be handled under the RERA-prescribed pro-rata adjustment mechanism — protecting both parties from windfall and loss
RERA authority oversight of major modifications provides structural discipline — preventing design changes that compromise project viability or allottee rights

Frequently Asked Questions

Can a promoter change the project plan after RERA registration?

Minor changes within an individual apartment (finishes, fixtures, internal walls) can be made with the written consent of the individual allottee. Significant alterations or additions to the sanctioned building plan or project specifications that affect common areas or multiple buyers require the prior written consent of at least two-thirds of allottees of the affected building or wing under Section 14(2) of the RERA Act, as well as updated disclosure on the state RERA portal.

What is considered a significant alteration under Section 14 of RERA?

The RERA Act itself does not exhaustively define 'significant alteration' but state RERA rules and RERA authority guidance provide clarification. Generally, significant alterations include: changes to the structural design or building footprint; addition or removal of floors; redesign of common areas, lobbies, or amenities; changes affecting the unit mix or carpet area of existing apartments; and changes to external elevations or building orientation. Minor cosmetic or finish changes within a unit typically do not require two-thirds consent.

What is the carpet area definition under RERA?

Under Section 2(k) of the RERA Act, carpet area is defined as the net usable floor area of an apartment, excluding the area covered by external walls, areas under services shafts, exclusive balcony or veranda area, and exclusive open terrace area — but including the area covered by the internal partition walls of the apartment. This RERA definition is mandatory for all sale agreements and supersedes any other area measurement basis that may have been used prior to RERA.

How is a change in carpet area handled under RERA?

A reduction or increase in the carpet area of a registered apartment must be disclosed to the allottee and handled in accordance with Section 14(2). For area changes up to 3% of the agreed carpet area, RERA rules in most states permit adjustment of the consideration payable on a pro-rata basis without requiring fresh allottee consent. Changes exceeding the permitted threshold require written consent from the individual allottee. Our team advises on the applicable state RERA provisions and manages the consent and disclosure process.

Does RERA modification apply to commercial projects?

Yes. Section 14 of the RERA Act applies to all registered real estate projects — both residential and commercial. Promoters of registered commercial projects must comply with the same consent and disclosure requirements for significant post-registration changes to sanctioned plans, unit areas, and common facilities as residential project promoters. The practical application of the two-thirds consent requirement in commercial projects — where unit configurations may be more diverse — requires careful management.
