Documents to check before buying a builder floor

Updated 1 Nov 2026

Why builder floors need extra care

A builder floor is one complete floor of a low-rise building on an individual plot. Several owners share one plot, one roof and one set of approvals, so the paperwork has to show clearly which part of the building is yours and that the whole building was built as approved.

Ownership and title

The registered sale deed (registry) for the floor you're buying, in the seller's name.
The chain of earlier deeds back to the original plot owner, so you can see how the seller came to own it.
If the seller holds the floor through a GPA (power of attorney) instead of a registered deed, take legal advice before going further.
An encumbrance check to make sure the floor isn't mortgaged or under dispute.

Approvals for the building

The sanctioned building plan from the local authority, showing the number of floors and the layout.
That the floor you're buying actually matches the sanctioned plan: same height, same layout, no unapproved extra floor.
The occupancy or completion certificate (OC/CC) where it applies. For a floor still under construction, find out when it's expected.

What exactly you're buying

Which floor, and its share of the land (often called the undivided share), written into the deed.
Roof and terrace rights: usually with the top floor, but check the deed rather than assume.
Parking: which slot is yours, and whether stilt parking is shared.
Common areas like stairs, lift and water tanks, and how their upkeep is shared between floors.

Dues and bills

Property tax receipts up to date.
Electricity and water connections in the floor's own name, with no pending bills.
For resale, a no-dues letter from the bank if the seller had a home loan on it.
