Occupancy Certificate vs Completion Certificate: What to Check

On 17 December 2024 the Supreme Court, deciding Rajendra Kumar Barjatya v U.P. Avas Evam Vikas Parishad, told electricity, water and sewer providers to connect buildings only once a completion or occupancy certificate is produced, and told banks to check the same before lending against a building. Overnight, the occupancy certificate went from a document buyers had vaguely heard of to one that decides whether a flat can be lived in legally. If a builder offers you keys without one, this guide is about why you should hesitate.

What the occupancy certificate actually certifies

The RERA Act defines an occupancy certificate in section 2(zf) as the certificate, "by whatever name called, issued by the competent authority permitting occupation of any building, as provided under local laws, which has provision for civic infrastructure such as water, sanitation and electricity."

Two points are in that definition. The OC is a permission to occupy. And the authority issues it only once the building has working civic infrastructure. Before issuing it, authorities usually want the fire department's final clearance, lift certificates, structural stability certificates from the architect and engineer, and confirmation that the building matches the sanctioned plan.

In Maharashtra it's called an occupation certificate. The name changes; the function doesn't.

What the completion certificate certifies

Section 2(q) defines the completion certificate as one "certifying that the real estate project has been developed according to the sanctioned plan, layout plan and specifications, as approved by the competent authority under the local laws."

So the CC looks backwards at the construction: was it built as approved. The OC looks forwards: can people now live in it. In many places the two are issued together or the OC follows the CC. Some local laws issue only one document that does both jobs, which is why the RERA definitions say "by whatever name called".

A warning for Mumbai and Pune buyers: there, "CC" in everyday use usually means the commencement certificate, the permission to start building. A broker saying a project "has CC" may mean construction was allowed to begin, not that it was finished.

Who issues them

The local planning or building authority, not RERA. Examples:

• Noida and Greater Noida: the Noida Authority or GNIDA, which also allot most of the land.
• Gurugram: the Directorate of Town and Country Planning (DTCP) for licensed group housing colonies.
• Mumbai: the BMC's building proposal department, or the relevant planning authority such as MMRDA or SRA for projects under them.
• Other cities: the municipal corporation or development authority that sanctioned the plan.

Section 11(4)(b) of the RERA Act makes it the promoter's job to obtain the CC or OC, or both, and to make them available to buyers individually or to the residents' association.

Partial OCs are common

Large projects often get an occupancy certificate tower by tower. A partial OC for Towers A to D says nothing about Tower F. Check that your tower, and ideally your floor range, is named in the certificate. The same goes for a project listed as ready to move: the listing can be right for the finished towers and wrong for yours.

What happens if a flat has no occupancy certificate

• Utility connections. After the December 2024 judgment, permanent electricity, water and sewer connections are meant to be given only on production of a CC or OC. Temporary construction connections cost more and can be cut.
• Home loans. Banks were directed to check the certificate before lending against a building, and many won't disburse the final tranche or lend on resale without it.
• Resale. A future buyer faces the same problems, so the flat is harder to sell and sells for less.
• Legal risk. Occupying a building without the permission the local law requires can attract penalties, and in the worst case, where the building deviates from the plan, action against the unauthorised part.
• Conveyance and handover. Section 17 of the RERA Act ties the builder's duty to execute the conveyance deed to the OC: within three months of it, unless local law says otherwise. No OC, no clock.

What people get wrong: they take possession "for fit-outs" before the OC, start living there, and assume the paperwork will follow. Sometimes it does. When it doesn't, the buyer has lost leverage, because the builder already holds the full payment. Section 19(10) requires you to take possession within two months of the OC; before the OC, you're not obliged to.

In 2022 the Supreme Court held, in Samruddhi Co-operative Housing Society v Mumbai Mahalaxmi Construction, that a builder's failure to obtain an occupancy certificate is a deficiency in service and a continuing wrong, so buyers could claim compensation even years later. That's a remedy, but a slow one. Better to insist on the certificate first.

How to check an occupancy certificate

1. Ask for a copy from the builder or seller, and check the project name, tower numbers, plot number and date.
2. Look on the RERA portal. Many promoters upload the OC to the project page once it's issued. On UP RERA, MahaRERA and HRERA, check the documents section of the project record.
3. Verify with the issuing authority. Several authorities publish OCs or allow verification online; otherwise a lawyer can confirm it at the office.
4. Match it to the plan. The number of floors and units in the OC should match the sanctioned plan and what's built. Extra floors added after approval are a problem.
5. For resale, ask the society or association whether the building has a full OC, and whether water and power are on permanent connections.

If the builder says the OC is "applied for"

It may be true, and an OC can take a few months after an application. Ask for the application's date and reference number, and for any objections the authority raised. Don't release the final payment tied to possession until the certificate is issued, and don't sign any handover letter that says you've accepted possession "without objection".

If you're looking at homes you can move into, start with ready-to-move projects in Mumbai, such as Lodha Woods in Kandivali East, or ready-to-move projects in Noida like Ambience Tiverton in Sector 50. For any of them, ask for the OC covering your tower before you negotiate on price.

Frequently asked questions

What is the difference between an occupancy certificate and a completion certificate?

A completion certificate confirms the building was constructed according to the sanctioned plan and specifications. An occupancy certificate permits people to occupy it and confirms water, sanitation and electricity are provided. Both are issued by the local building authority.

Who issues the occupancy certificate?

The local planning or building authority that sanctioned the plan, such as the municipal corporation or the development authority. In Gurugram's licensed colonies it is DTCP Haryana, and in Noida the Noida Authority.

Can I get electricity and water without an OC?

Since the Supreme Court's December 2024 directions in the Barjatya case, utilities are to give permanent electricity, water and sewer connections only after a completion or occupancy certificate is produced.

Can I take possession of a flat without an occupancy certificate?

You are not obliged to. The RERA Act requires the buyer to take possession within two months of the OC, and the builder is responsible for obtaining it. Taking possession earlier weakens your position if the certificate is delayed.
