The day you take possession is the last day you hold real negotiating power over your builder, and most buyers spend it taking photographs for the family group instead of measurements for the file. Everything wrong with the flat is easiest to fix before you sign the possession letter, hardest after. This checklist is the difference.
Key takeaways
- Verify the occupancy certificate before anything else; a flat without OC has not been certified fit to live in.
- Measure the carpet area against the agreement; at ANAROCK's 2025 top-7-city average price of Rs 9,260 per sq ft, even a 20 sq ft gap is Rs 1.85 lakh.
- Record every defect in a written snag list the builder acknowledges before you sign an unconditional possession letter.
- RERA Section 14(3) gives you a 5-year defect liability period, with a 30-day rectification clock once you report a defect.
Meera's second visit
Names and numbers in this story are illustrative. Meera, our time-poor Thane buyer, nearly signed the possession letter on the spot; the lobby was beautiful and the site manager was in a hurry. Her broker persuaded her to book a second visit and bring a checklist, a tape measure and a phone charger. Two hours later the file contained: seepage stains inside the bedroom wardrobe wall, three windows that would not lock, a kitchen tap running brown, a balcony door misaligned, and a working charger test that found two dead power points. The builder's team fixed all of it in twelve days, because the snag list stood between them and her final instalment. The buyers who signed on Meera's first-visit schedule got the same defects fixed on the builder's schedule, which is to say slowly or never.
Why the timing is everything
Think of possession like accepting a restaurant order. While the plate is still in the waiter's hand, a wrong dish gets replaced in minutes. Once you have eaten half of it, the conversation changes entirely. The final instalment, typically 5 to 10 percent of the price plus handover charges, is the plate still in the waiter's hand. India's top 7 cities saw about 3.96 lakh homes sold in 2025 (ANAROCK, January 2026); a large share of handovers happen in end-of-quarter batches, when site teams are rushing, which is precisely when unchecked flats absorb unfixed defects.
The 10-point inspection
- 1
Occupancy certificate first
Ask for the OC (or its application status) before the visit. No OC means the building is not certified for occupation; understand the difference in our OC vs CC guide, linked below, before you go.
- 2
Carry the agreement's specification annexure
Flooring brand, fittings, paint, kitchen platform: the annexure is the promised spec. You are inspecting against it, not against the sample flat's memory.
- 3
Measure the carpet area
Tape-measure wall to wall, room by room, and total it against the agreement's carpet area. Shortfalls have a legal remedy; measurement is the trigger.
- 4
Water test every wet area
Run taps and showers at full for several minutes, flush every WC, look under sinks, check drainage speed on balconies and bathrooms. Seepage stains on fresh paint are the tell.
- 5
Electrical test every point
A phone charger tests every socket in ten minutes. Check the DB board labeling, earthing certificate, and that the meter is in your name or transferable.
- 6
Doors, windows, locks, latches
Open, close and lock every one. Misaligned frames and non-locking windows are the most common snag-list items and the cheapest to fix now.
- 7
Walls, ceilings, flooring
Sight along walls for cracks and damp patches, tap tiles for hollows, check level with a marble. Cosmetic now, expensive later.
- 8
Common areas and promised amenities
Lifts commissioned, fire systems visible, promised amenities existing rather than upcoming. Sanctioned-plan deviations belong on the snag list too.
- 9
The document bundle
OC copy, possession letter draft, maintenance agreement and rates, warranties for fittings, allotted parking in writing, society formation status.
- 10
Write the snag list, get it acknowledged
Dated, itemised, signed by the builder's representative, with a committed rectification date. Photograph everything. Only then discuss the possession letter.

The OC check needs the certificate, not the status
A project page that reads Completed is not an occupancy certificate. In ReraGenie's analysis of the 55,995 published MahaRERA projects as updated on 29 September 2026, 21,679 carry Completed status, and 4,422 of those (20.4%) have no file in the occupancy certificate slot of their filing. An empty slot does not prove the certificate is missing, since a promoter can file it under another name or in another slot, but it does mean the status line cannot stand in for the document. Ask for the OC itself, and read our OC vs CC guide for what it certifies that a completion certificate does not.
The area check deserves its own paragraph
Carpet area is the one defect you cannot see. At the 2025 top-7-city average of Rs 9,260 per square foot (ANAROCK, January 2026, up 8 percent in the year), a 650 sq ft flat that measures 630 sq ft delivered is Rs 1.85 lakh paid for absent floor. RERA defines carpet area precisely and your agreement states it; if your tape measure disagrees with the agreement, the remedy is a proportionate refund, and the method is in our guide to carpet area shortfall refunds. Bring the definition along: carpet vs built-up vs super built-up explains what is and is not inside the number.
Your safety net after the keys: 5 years, 30 days
The inspection is not your last chance, it is your best one. Section 14(3) of the RERA Act holds the promoter liable for structural defects and deficiencies in workmanship, quality and services for 5 years from possession. Report a covered defect and the promoter must rectify it within 30 days at no charge, failing which you are entitled to compensation. The snag list matters here too: a documented, acknowledged handover file makes every later Section 14(3) claim cleaner, and if the builder stops responding, the complaint route is mapped in how to file a RERA complaint.
Sign nothing unconditional on inspection day. A possession letter that says you accept the flat "in full satisfaction" is the builder's document; a possession letter accompanied by an acknowledged snag list with dates is yours. Both are legal. Only one protects you.
What ReraGenie adds before you ever reach this day
The handover is the end of a story the filings have been telling for years. The Rs 499 ReraGenie buyer report shows, for a covered project, whether the OC and completion filings exist, where construction stands against the promised date, and the promoter's delivery record and complaint count across their other registrations, which is a decent forecast of how your snag list will be treated. Meera's report had shown her builder finishing late on earlier projects with few complaints on record, which is exactly what she got: twelve days, but done. If your possession date is approaching, sign up on ReraGenie and walk in knowing the builder's handover record, with the project watch that comes free with the report emailing you when the OC appears on the filing.
The one-line summary
Possession day is a two-hour inspection with a tape measure, a charger and a snag list, backed by a 5-year law. Spend the two hours; the alternative is spending years. If possession day keeps not arriving even though the OC has been issued, that is a different problem with different remedies: OC received, keys withheld. And if you are offered the keys before the OC exists at all, read what you sign away by moving in early before you accept them. If the clubhouse or garden the brochure promised is still a fenced slab on inspection day, put it on the snag list and read amenities promised, amenities delivered for the document that makes it enforceable. Once the keys are genuinely yours, the clock that matters is the handover of the building itself: from possession to society covers the first twelve months.
