The call finally comes. Your builder says the flat is ready and possession is scheduled for next week.

After 2 or 3 years of EMIs, rent and waiting, that call feels like the finish line. It isn’t, not quite. It’s the last checkpoint where you still hold some leverage.

Once you sign the possession letter and take the keys, the balance shifts. A crack, a leaking pipe or a missing fitting you didn’t flag on day one becomes your problem to chase, not the builder’s problem to fix. This checklist walks through what to check before you sign anything, room by room and document by document, so the excitement of moving in doesn’t turn into a year of calls to the site office.

Why the possession day inspection matters

Most buyers treat possession as a formality: collect the keys, take a few photos, sign the form, start moving furniture in.

That works fine if nothing is wrong with the flat. It works badly if something is.

Once you sign the possession letter without listing defects, you’ve told the builder in writing that you accepted the unit as it stood. Getting a leak or a cracked wall fixed after that gets a lot harder, even though Section 14(3) of RERA gives you a 5-year defect liability period for structural issues.

Get your paperwork in order before you visit

Do this before you step into the flat, not after.

Ask the builder for the possession letter, the demand letter for final dues, and a copy of the occupancy certificate for the specific tower and floor your flat is on. Some projects get a part OC for one tower while the rest is still under construction. Read the letter carefully. It should mention your flat number, the built-up and carpet area, and the exact date of offer of possession.

If you haven’t already gone through the sale deed, allotment letter and approval documents, do that first. We’ve covered this in more depth in how to check property documents before buying a house in India. Possession day isn’t the time to discover a mismatch between what’s in the agreement and what’s on paper.

Also confirm whether stamp duty and registration are actually done, or whether that’s still pending on your side. Our guide on stamp duty and registration charges in India breaks down how those numbers are calculated.

Confirm the occupancy certificate before you sign

An occupancy certificate (OC) is the local authority’s confirmation that the building is safe to live in and matches the sanctioned plan. No OC means no legal permission to occupy the flat, whatever you’re told on the phone.

Ask for a copy, not a verbal assurance. Check the date, the tower or block name, and whether it actually covers your unit. If the project only has a part OC, get exactly what’s covered (and what isn’t) in writing. Our piece on what RERA is and how it protects property buyers explains why this one document matters more than most buyers realize.

Recheck the area you’re actually paying for

Builders often market the super built-up area, and the usable carpet area can be 20 to 30% smaller. RERA requires carpet area to be stated clearly in the agreement, but it’s still worth measuring the flat yourself.

Bring a laser measure or a tape. Measure each room’s length and width and add up the totals. Compare that to the carpet area in your agreement. A gap of a few square feet can happen because of wall thickness and rounding. A gap of 50 or 100 sq ft is a conversation to have with the builder before you sign anything.

Structural and civil checks

Walk every room with the lights on and curtains open, so you’re not missing damp patches in dim corners.

Ceiling and walls

Look up for water stains, cracks or a slightly wavy surface: signs of a leak from the floor above or the terrace. Hairline cracks where the wall meets the ceiling are common and mostly harmless. A diagonal crack running from a window or door corner is not; get that checked by a structural engineer before you accept the flat.

Dampness

Run your palm along the walls near the bathroom, kitchen and any external wall. A patch that feels damp or slightly cooler than the rest usually means water is finding its way in from somewhere.

Flooring

Tap a few tiles in each room with a coin, near the walls and in the centre. A hollow, drum-like sound usually means the tile isn’t bonded properly and will crack or lift within a year or two.

Electrical checks

Switch on every light point, fan point and socket, one by one. Carry a small phone charger or lamp and plug it into every socket to confirm power actually reaches it, not just that the switch clicks.

Open the electrical meter box and note the meter number and reading. Ask whether the connection is in your name yet, or whether that’s a separate process on your side.

Test earthing at a couple of points with a basic socket tester (under ₹200, worth carrying). Check the MCB distribution board: it should be labelled, with separate circuits for lights, plugs and heavy loads like the geyser and AC.

Plumbing and water checks

Turn on every tap and check pressure and flow. Let it run for a minute and watch for discolouration, which can point to old or rusted pipes.

Flush every toilet and check the tank refills at a normal pace. Check under every sink and behind the geyser for damp patches or a slow drip; these are easy to miss on a quick walkthrough.

Ask about the water source (municipal, borewell or tanker) and whether that’s included in maintenance or billed separately. If there’s an overhead tank, ask when it was last cleaned.

Doors, windows and fittings

Open and close every door and window in the flat. A door that scrapes the floor or a window that won’t latch is a small fix now and an annoyance for years if you let it go.

Check that fittings match what’s in your agreement or brochure: the kitchen, wardrobes, sanitary fittings, AC provisioning points. Builders sometimes swap a promised brand for a cheaper one and hope nobody checks.

Look at paint quality in corners and behind where furniture will sit; that’s usually where shortcuts show up first.

Common areas and amenities

If you’re buying into a project rather than an independent villa, don’t stop your inspection at your own front door.

Walk the lobby, staircase, lift and parking area. Check whether the lifts work and whether fire safety equipment (extinguishers, hose reels, exit signage) is actually installed, not just shown in the sales render. If the clubhouse, pool or garden aren’t ready, get the handover timeline in writing.

Build your snag list before you sign

Write down every issue you find, room by room, with a photo or short video for each one. Don’t rely on memory or a verbal chat with the site engineer.

Share this list with the builder in writing, over email, not just a WhatsApp message that gets buried under 200 other chats. Ask for a rectification date on each item, not a vague “we’ll look into it.”

For anything major (structural cracks, a lift that doesn’t work, a missing OC) hold off on signing until it’s resolved. For minor cosmetic issues, you can usually take possession while the builder finishes the fixes, as long as the commitment is on paper.

After you sign: what your 5-year cover actually protects

Once you accept possession and clear your final dues, maintenance for anything outside the defect cover becomes your responsibility.

Section 14(3) of RERA gives you 5 years from the date of possession to report structural defects, workmanship issues and water seepage caused by construction problems. The builder then has 30 days to fix a reported issue without charging you. That’s a strong protection on paper, and it works best when problems are reported in writing with a paper trail behind them.

Keep your inspection report, snag list, photos and builder correspondence in one folder (a simple email folder is enough). If you ever need to raise a complaint with your state RERA authority, this is the evidence that carries your case.

If the builder delays or pushes back

Some builders push back on a long snag list, especially close to a possession date they’ve already missed once.

Stay factual. Point back to your written snag list and the date you shared it. If the builder stalls beyond a reasonable window (2 to 3 weeks for minor items), you can escalate to your state RERA authority with your inspection report as evidence. Keep a copy of every email and message. RERA authorities generally respond better to a documented timeline than to a general complaint about “poor quality.”
