Builder Changed the Plan or Area? What Section 14 Allows, and What It Doesn’t
A park becomes a tower, your flat shrinks by 40 sq ft, the clubhouse disappears from the brochure. RERA puts firm limits on what a builder can change after you book, and gives you a say in the rest.
Quick Answer
Under Section 14 of the RERA Act, a builder must build as per the sanctioned plans and the agreement. Changes to your flat need your written consent (only minor, non-structural changes are allowed without it). Changes to the building or common areas need written consent of at least two-thirds of the buyers. If the area is cut, you are owed a refund.

What Section 14 Says
Section 14(1) requires the builder to develop and complete the project according to the plans, layout plans and specifications approved by the competent authorities. Section 14(2) then sets two levels of protection: Confirmed
Change to
Whose consent
Section
Your own flat or plot: plan, specifications, fixtures, fittings, amenities in your agreement
Your prior written consent
14(2)(i)
Minor changes you ask for, or needed for architectural or structural reasons
None, but certified by an architect or engineer and intimated to you
14(2)(i) proviso
The building or common areas: sanctioned plans, layout, specifications
Prior written consent of at least two-thirds of buyers in that building (builder excluded)
14(2)(ii)
For the two-thirds count, each buyer counts as one however many flats they hold. The builder’s own unsold flats don’t count.
What Counts as a "Minor" Change?
The Act defines it by exclusion. A minor change does not include any structural change: adding to the area or changing the height, removing part of the building, building, removing or cutting into any wall, partition, column, beam, joist or floor, or changing or closing any required way in or out. Shifting a switchboard or a window grill is minor. Moving a wall, adding a floor or shrinking your balcony is not.
Common Situations, and Where You Stand
Extra floors or a new tower on the layout
A change to the building or layout needs written consent of two-thirds of buyers under Section 14(2)(ii), plus fresh approval from the planning authority. Without both, it can be challenged before RERA.
Park, playground or clubhouse moved or removed
Common areas and amenities shown in the sanctioned layout and your agreement are protected the same way. Keep the brochure, but rely on the agreement and the plans uploaded on the RERA page.
Your flat’s layout changed
Needs your prior written consent unless it is a genuinely minor, non-structural change. A builder letter saying "please note the revised plan" is not consent.
Carpet area smaller than agreed
The agreement’s area clause decides the adjustment. The model agreement in many states’ RERA rules requires the builder to refund for any reduction and allows a demand for an increase only up to a small limit (commonly 3%). Check the clause in your agreement.
"Super area" increased with a fresh demand
Under RERA, the price is tied to carpet area. A demand based on an increased super or saleable area, with your carpet area unchanged, should be questioned in writing.
Specifications downgraded
Flooring, fittings and fixtures listed in the agreement are part of what you bought. A cheaper substitute needs your consent or a price adjustment.
The Case Everyone Remembers
In Supertech Ltd v Emerald Court Owner Resident Welfare Association (31 August 2021), the Supreme Court ordered the demolition of two 40-storey towers in Noida. The towers had been added to the project in breach of building rules, without the consent of the existing flat owners required under the Uttar Pradesh apartment law. They were brought down in August 2022, and buyers in those towers were ordered to be refunded with interest. The case was decided under state law rather than RERA, but Section 14(2)(ii) sets the same two-thirds consent principle nationally. Reported
What to Do, Step by Step
1
Compare against the documents
Your agreement for sale, the plans annexed to it, and the sanctioned plans and layout on the project’s RERA page. See how to read a RERA project page.
2
Ask for the basis in writing
The revised sanctioned plan, the authority’s approval, and the consent record if the builder claims two-thirds consent.
3
Don’t sign a blanket consent
Consent forms are sometimes bundled with demand letters or possession papers. Read before you sign, and consent only to a specific, described change if you agree.
4
Talk to other buyers
Two-thirds is counted across buyers in the building. A residents’ group can respond together and file together.
5
Complain to RERA
Under Section 31, ask the Authority to stop or reverse the change, or for an adjustment. If the change means the builder can’t deliver what was agreed, you can ask to withdraw with a refund and interest under Section 18.
Frequently Asked Questions
Can a builder change the floor plan after booking?
Not without your prior written consent, under Section 14(2)(i) of the RERA Act. The only exception is a minor, non-structural change, which must be certified by an architect or engineer and intimated to you. Moving walls, changing room sizes or reducing balconies are structural and need your consent.
Can the builder add floors or towers to an approved project?
Only with fresh approval from the planning authority and the prior written consent of at least two-thirds of the buyers in that building, under Section 14(2)(ii). Each buyer counts as one, regardless of how many flats they own, and the builder’s unsold units do not count.
What if my carpet area is less than in the agreement?
You are owed an adjustment under the area clause of your agreement for sale. The model agreement in many states’ RERA rules requires a refund for any reduction in carpet area, and limits any extra demand for an increase to a small percentage, commonly 3%. Measure before you take possession and raise the shortfall in writing.
What is a minor alteration under RERA?
A change that is not structural. The Act excludes from "minor" any addition to area or height, removing part of the building, cutting or removing walls, partitions, columns, beams, joists or floors, and changing or closing required access. Minor changes may be ones you request or ones needed for architectural or structural reasons, certified by an architect or engineer.
Can I cancel and get a refund if the builder changes the plan?
If the change breaches Section 14 or means the builder cannot deliver the flat as agreed, you can complain to the RERA Authority and ask to withdraw with a refund and interest under Section 18. The outcome depends on the change and your agreement, so keep every plan, brochure and letter.
Does a brochure count as a promise?
Brochures and advertisements are covered by Section 12: if you suffer loss because of false information in them, the builder must compensate you, and you may withdraw with a refund and interest. The agreement for sale and sanctioned plans are still the strongest evidence of what you bought.
