IndiaThe builder made changes to the approved plan without consent. Is this allowed?
No, a builder cannot make changes to the approved plan without prior consent from the competent authority and affected buyers — such changes are illegal and may attract penalties or cancellation of approval.
What the Law Says
Indian law strictly prohibits unauthorised modifications to sanctioned building plans. Both the Real Estate (Regulation and Development) Act, 2016 (RERA) and state-specific town planning laws require explicit approvals before any deviation.
Under RERA, any alteration to the sanctioned plan — especially structural or layout changes affecting carpet area, common areas, or utility provisions — requires written consent from at least two-thirds of allottees *and* fresh approval from the competent authority (e.g., municipal corporation or DTCP).
The Supreme Court in Pioneer Urban Land & Infrastructure Ltd. v. Union of India (2019) affirmed that RERA is a beneficial legislation meant to protect homebuyers, and unilateral plan changes violate the statutory trust placed in developers.
State-level building bye-laws (e.g., Maharashtra Ownership Flats Act, 1963 and Tamil Nadu Town and Country Planning Act, 1971) also mandate that no construction shall deviate from the sanctioned plan without re-approval — otherwise, the structure may be declared 'unauthorised' and liable for demolition.
Statutory TextNo promoter shall make any addition or alteration to the approved plans, specifications or amenities after the registration of the real estate project… without the prior written consent of two-thirds of the allottees…
— Real Estate (Regulation and Development) Act, 2016, s. 14(2) — Duties of promoter
Statutory TextAny change in the sanctioned plan… shall be carried out only with the prior written consent of the allottee concerned.
— Real Estate (Regulation and Development) Rules, 2016, Rule 11(2)
What Courts Have Said
Indian courts have consistently held that unauthorised plan changes breach statutory duties and consumer rights, entitling buyers to remedies including refund, compensation, or specific performance.
Held that Section 14 of RERA imposes strict liability on promoters; unilateral changes violate the statutory contract and frustrate buyer expectations — consent is mandatory, not optional.
Declared that deviations beyond 5% in floor area ratio (FAR) or height without fresh sanction render the entire building non-compliant and subject to demolition under TN TCP Act.
What to Do
Immediately collect copies of the original sanctioned plan, builder’s revised layout, and RERA registration details.
File a complaint with the State RERA Authority within 3 months — cite Section 14(2) of RERA and demand refund/compensation.
Simultaneously lodge a grievance with the local municipal authority or DTCP for unauthorised construction.
If more than 25% of allottees are affected, approach RERA for class action or seek injunction in civil court.
Preserve all payment receipts, booking agreements, and communication — these are critical evidence.
