Construction Defects After Redevelopment: What Courts and Consumer Commissions Have Ordered

If a redeveloped building leaks, cracks, or shows weak workmanship after members move back in, the developer — not the flat owners — is legally bound to set it right at his own cost. The clearest source of this duty today is Section 14(3) of the Real Estate (Regulation and Development) Act, 2016 (RERA), which gives allottees a five-year defect-liability period from the date of possession. If any structural defect, or any defect in workmanship, quality, or the provision of services, is brought to the promoter’s notice within those five years, the promoter must rectify it — the rule requires this within about thirty days — without charging the society anything extra. Where a builder refuses, MahaRERA, the consumer commissions, and the civil courts have repeatedly ordered developers to repair the faults, reimburse repairs the society already paid for, or pay compensation. This page explains the legal principle, how these forums have reasoned, and the practical steps your society should take. It is general legal information, not legal advice for your building.

Where the builder’s duty to fix defects comes from

Fixing a badly built structure is not a goodwill gesture from the developer. It is a statutory duty, and both the regulator and the courts treat a broken promise on quality as something a society or an individual member can enforce. Two laws matter, depending on when your building was handed over.

RERA Section 14(3): the five-year rule (current position)

Section 14(3) is the heart of the modern defect law. The word “defect” here is wide — it covers structural defects such as cracks in columns, beams, or slabs, and also defects in workmanship, quality, or services such as leaking terraces, failing plumbing, or lifts that do not run. If the defect surfaces within five years of possession and the allottee reports it in writing, the promoter is obliged to repair it at no extra cost. If the promoter fails to carry out that repair, the allottee becomes entitled to compensation under the Act. A related provision, Section 14 (main part), bars the promoter from changing the sanctioned plans without the consent of at least two-thirds of the allottees — so building differently from what was approved is itself a breach members can challenge. Complaints under RERA are filed with the Authority under Section 31; in Maharashtra that Authority is MahaRERA. For the full picture of what a promoter must and must not do, see our note on MahaRERA promoter obligations.

MOFA, 1963: the older duty (buildings handed over before RERA)

Before RERA, the Maharashtra Ownership Flats Act, 1963 (MOFA) governed the relationship between promoter and flat purchaser. MOFA historically required the promoter to rectify, free of charge, defects in the building or in the materials used, and any unauthorised change in construction, if brought to notice within a set period after possession — and to pay reasonable compensation if he ignored a genuine complaint. MOFA also placed a continuing duty on the promoter under Section 11 to convey title to the society and, until conveyance, to bear the building’s outgoings and taxes. Many pre-RERA disputes in Mumbai were decided on these principles, and they still govern buildings possessed before RERA came into force in 2017. If your society is still chasing the developer for title, our related judgment page on a builder’s duty to pay outgoings until conveyance is worth reading alongside this one.

Flat owners are “consumers” — a second route

RERA is not the only door. The Consumer Protection Act, 2019 gives a separate remedy for “deficiency in service,” and Indian courts — including the Supreme Court of India — have long held that a person who buys a flat is a “consumer” and that poor, incomplete, or defective construction is a deficiency in service. That lets a member, or the society acting for its members, approach the consumer commissions instead of, or alongside, MahaRERA. The consumer forums are tiered by the value of the claim — broadly, the District Commission for smaller claims, the State Commission for larger ones, and the National Commission at the top. Because these monetary thresholds are revised from time to time, confirm the current limits before you file. The practical advantage of the consumer route is that it is built around awarding compensation for the loss and inconvenience defects cause, not only ordering a repair.

How courts and commissions have reasoned

Reading across reported matters from the Bombay High Court, MahaRERA, and the State and National Consumer Commissions, a consistent line of reasoning emerges. First, the forums start from the statute: a promoter who sold flats promising sound construction cannot escape liability by pointing to a completion certificate or to the fact that the society is now registered. Completion means the project is finished, not that it was finished well. Second, they place the burden on the developer to show the fault is normal wear and tear or the society’s own neglect, rather than on residents to prove bad workmanship beyond doubt. Third, and most important in practice, they decide on evidence — an independent structural engineer’s report and dated written complaints carry far more weight than oral assertions. Where a society brought those two things, relief has tended to follow.

What the courts and commissions have actually ordered

The relief granted to societies and flat owners tends to fall into a few clear patterns:

• Directions to repair: the builder is ordered to fix leakages, cracks, plumbing, waterproofing, or structural faults at his own cost, within a fixed time set by the forum.
• Reimbursement of repair costs: where the society has already spent its own money rectifying defects the builder ignored, the developer is directed to repay that amount.
• Compensation and interest: for the loss, inconvenience, and hardship caused to residents, sometimes with interest running until payment.
• Costs of litigation: so that pursuing a legitimate claim does not become a further financial burden on the society.
• Refund with interest in delay-linked cases: where defects sit alongside a failure to hand over on time, Section 18 of RERA allows a refund with interest, or interest for the period of delay, in addition to defect relief.

The exact order always depends on the evidence and the facts pleaded. Two societies with similar cracks can get very different outcomes purely because one documented the problem properly and the other did not.

What legally counts as a construction defect

Not every crack or stain is a legal defect — ordinary wear and poor maintenance by residents do not count. But the following commonly qualify when they stem from the quality of construction rather than normal use:

• Recurring seepage and leakage from terraces, external walls, bathrooms, or common ducts.
• Cracks in walls, columns, beams, or slabs that point to weak workmanship or design.
• Plaster, tiles, or dado falling off soon after possession.
• Faulty drainage, waterproofing, or plumbing that keeps failing despite repairs.
• Use of substandard materials, or deviation from the sanctioned plans without the two-thirds consent Section 14 requires.
• Lifts, fire-fighting systems, water pumps, or common amenities that do not work as promised.

How your society should document and pursue a defect claim

Strong claims are won on paper long before they reach a forum. Whether you go to MahaRERA, a consumer commission, or court, the same groundwork applies:

1. Inspect jointly at handover. Prepare a snag list when you take possession and get it signed by the developer’s representative. Our guide on possession and corpus explains exactly what to check before you accept the building.
2. Get an independent expert report. Appoint a structural engineer or licensed surveyor to inspect and certify the defects. This report is usually the single most important piece of evidence in any defect claim.
3. Give written notice within the defect-liability period. Send a dated letter or email to the developer listing each defect and demanding rectification. Keep proof of delivery — a courier receipt, registered-post acknowledgement, or email trail.
4. Preserve your paperwork. Keep the development agreement, sanctioned plans, possession letters, occupancy certificate, and every piece of correspondence about quality. Weak or one-sided drafting is a common problem — consider a professional tender and agreement review before you sign, so defect obligations are watertight.
5. Choose the right forum. MahaRERA is built for allottees and is often faster for registered projects; consumer commissions specialise in compensation for deficiency in service; civil courts remain an option for larger or more complex disputes.
6. Act as a society. For common-area and structural defects, pass a managing-committee resolution and pursue the claim in the society’s name, so relief benefits every member rather than one flat.

Which forum decides a defect claim?

Choosing the wrong forum wastes months. A useful rule of thumb: a dispute against the developer over construction quality goes to RERA, a consumer commission, or a civil court, while a dispute among members or with the committee over how the society is run goes to the Co-operative Court.

What this means for your society

The law is firmly on the side of members who act promptly and keep records. A developer cannot walk away from a badly built structure simply because the project is “complete” and the society is registered. But the window to enforce quality is real and limited — treat the five-year period under Section 14(3) as a live deadline from day one of possession, not something to worry about later. Report defects in writing, back them with an independent expert’s report, decide as a society through a committee resolution, and pursue rectification firmly through the correct forum. Do those four things and your society is in a strong position; skip them and even a genuine defect can become hard to prove.
