Section 14(3) of the Real Estate (Regulation and Development) Act, 2016, gives every Worli buyer a five-year warranty against structural defects and workmanship failures, enforceable directly against the developer. Property Butler's claims tracking across 14 Worli buildings shows fewer than 19% of buyers ever file a formal defect notice within the protected window — even when measurable issues are present. The warranty is among the most under-utilised legal protections in Indian real estate. This is the playbook to actually use it.
The 5-Year Clock — When It Starts and What It Covers
The defect liability period runs from the date of handover of possession to the buyer, not from the date of OC. It covers structural defects, workmanship failures, defects in service, and defects in quality of materials supplied — provided the defect is brought to the developer's notice within the 5-year window. The developer must rectify within 30 days at no cost, or compensate. Wear-and-tear, buyer-induced damage, and defects caused by post-handover alteration by anyone other than the original buyer are excluded.
The 12 Most Common Worli Defect Categories Property Butler Tracks
| Defect Category | Frequency in Worli (Year 1-5) | Typical Rectification Cost (Builder Bears) |
|---|---|---|
| Bathroom waterproofing failure | High — 28% of units | ₹85,000-₹2.4 lakh |
| External facade seepage | Medium — 17% of units | ₹1.2-3.5 lakh |
| Wooden flooring warping / cupping | Medium — 14% of units | ₹3-12 lakh per room |
| HVAC condensate leakage | Medium — 22% of units | ₹40,000-₹1.5 lakh |
| Window glazing seal failure | Medium-high — 24% | ₹15,000-₹50,000 per panel |
| Lift downtime exceeding spec | Building-level — 31% of buildings | Maintenance contract recovery |
| Common-area marble cracking | Building-level — 18% | ₹4-15 lakh society-wide |
| Basement waterproofing failure | Building-level — 23% | ₹25-90 lakh society-wide |
| Plumbing chase concealed leakage | Medium — 19% | ₹1-4 lakh per incident |
| Electrical earthing inadequate | Low — 6% | ₹50,000-₹2 lakh |
| Concealed wiring routing failure | Low — 8% | ₹80,000-₹3 lakh |
| Gas supply pressure inconsistency | Low — 7% | ₹20,000-₹1 lakh |
Why Worli Buyers Don't Claim — and Why That's Money on the Table
Three reasons dominate. First, the perception that filing a complaint will create friction with the developer or society and depress resale value. In practice, RERA notices are not part of the title chain and do not appear in standard property due-diligence searches; the resale impact is negligible if the issue is rectified. Second, the assumption that small defects are too small to bother. A bathroom waterproofing failure in year 3 that the buyer self-rectifies for ₹1.2 lakh becomes ₹1.2 lakh of permanent loss; the same defect notified within window costs the developer, not the buyer. Third, lack of process knowledge — most buyers do not know what a Section 14(3) notice looks like, how to serve it, or what to do if the developer ignores it.

The Six-Step Claim Playbook
- Document the defect immediately. Photographs with date stamps, video showing the defect in operation (e.g., water flowing from a leak point during normal use), and any maintenance complaints already raised through the society MIS. Preserve the original packaging and receipts of any product whose failure caused the defect.
- Get an independent assessment. A structural consultant for major issues (waterproofing, cracking, lift) at ₹15,000-₹50,000 per inspection. The independent report is decisive evidence — it shifts the burden from the buyer's allegation to the developer's denial.
- Serve a written notice on the developer. A Section 14(3) notice does not require a lawyer to draft, though using one is advisable for major matters. The notice should: identify the unit, describe the defect, attach the independent report, demand rectification within 30 days, and reserve the right to compensation if the deadline is missed. Send by registered post with acknowledgment due, and email to the developer's customer-care address with read receipt requested.
- Wait the 30 days. If the developer responds and rectifies, the matter is closed. If the developer disputes the defect, secure the disagreement in writing. If the developer ignores the notice, prepare for the next step.
- File a complaint with MahaRERA. Online filing on the MahaRERA portal. Filing fee starts at ₹5,000. Include the original notice, the developer's response (or proof of non-response), the independent assessment, and the cost estimate for rectification. MahaRERA case timelines for Worli matters average 4-8 months for first hearing, 8-14 months for final order.
- Enforce the order. MahaRERA orders carry the same enforcement teeth as a civil decree. Most Tier 1 developers comply on receipt of order. For non-compliant respondents, recovery proceedings can be initiated through the District Collector.
What the Developer Cannot Do
✗ Defenses Developers Sometimes Try (Often Fail)
- "Warranty period was only 1 year, not 5" — Section 14(3) is non-derogable
- "You modified the unit, warranty is void" — only defects caused by post-handover alteration are excluded
- "Your maintenance is delinquent" — separate matter, does not affect defect liability
- "This is a society common area, not your unit" — applies but society can claim collectively
- "You signed an indemnity at handover" — contractual indemnities cannot override statutory rights
✓ Buyer Rights Worth Asserting
- Rectification at developer's cost within 30 days of notice
- Cash compensation in lieu of rectification if buyer prefers
- Interest on the value of defect from date of notice till rectification
- Recovery of independent inspection costs from developer
- Society-level collective claim for common-area defects
The Society Collective Claim — Worli's Most Underused Lever
Common-area defects in Worli buildings — basement waterproofing, lift system underperformance, common-area marble cracking, lobby finishing failures — typically cost ₹15-90 lakh to rectify. The cost is borne by the society or condominium when the issue surfaces, often years after the developer has exited. A society-level Section 14(3) collective claim, filed by the society's elected committee with proper resolution and signatures of the affected members, has materially better leverage than individual claims. Property Butler's tracking shows that society collective claims in Worli have an 81% recovery rate (full or substantial), versus 47% for individual unit-level claims.
The window for collective claims is the same five years from the building's handover (typically marked by the date of formation of the society or the date of first sale deed). Worli societies are well-advised to commission a comprehensive defect audit by a structural consultant in year 4, file collective claims for any documented issues before year 5, and avoid the cost-shifting that otherwise becomes inevitable.
Frequently Asked Questions
My agreement says "defect liability period is 1 year" — is this enforceable?
No. Section 14(3) is a statutory right; it cannot be reduced or waived by contract. Any clause in the agreement to sale shortening the defect liability period below 5 years is void to that extent. The 5-year period applies regardless of what the agreement states.
I bought a Worli flat in resale — does the warranty pass to me?
Yes. The warranty attaches to the unit, not the original allottee. As the new owner you can serve a Section 14(3) notice for any defect within the original 5-year window from the first handover. The notice should attach proof of your ownership. Some developers initially resist resale-buyer claims, but MahaRERA jurisprudence has consistently held the warranty is transferable.
What if the developer has been struck off or wound up?
More limited remedies, but not zero. Where the developer is a corporate entity that has been wound up, the warranty does not survive against an entity that no longer exists. However, claims against directors for personal liability under Section 71 (false declarations) and against the project's escrow account remain. For partnership-firm developers, the partners' personal liability persists. Consult a RERA-empanelled lawyer for the specific structure.
Can I get cash instead of rectification?
Yes — if rectification is impractical or the buyer prefers cash settlement. The amount should reflect actual rectification cost from a reputable contractor, not a notional figure. Property Butler's experience suggests cash settlement is faster (3-6 months versus 8-14 for rectification orders) and cleaner, especially for finishing-related defects where buyer's interior aesthetics may differ from the developer's standard rectification approach.
What does it cost to file and pursue a Section 14(3) claim?
For an individual claim: filing fee ₹5,000-₹10,000, lawyer fees ₹40,000-₹1.2 lakh depending on complexity, independent inspection ₹15,000-₹50,000. For a society collective claim: ₹1.5-3 lakh total, typically a tiny fraction of the recovery. Most claims settle without litigation if the notice is well-drafted and supported by independent assessment.
