OC vs CC: What Each Certificate Covers for a Bengaluru Flat Buyer Under RERA

Two certificates sit near the end of a Bengaluru flat purchase, and buyers ask about them in the same breath: the occupancy certificate and the completion certificate. A promoter's handover email may mention one and not the other. A resale seller may produce one and say the other is on its way. Knowing what each one certifies is the first step to knowing which one to ask for.

The Ministry of Housing and Urban Affairs explains the difference in its July 2025 FAQs on the Real Estate (Regulation and Development) Act, 2016. Its answers are short, but they draw a clear line between a certificate about a building being fit to live in and a certificate about a project being built as approved.

The short answer. MoHUA's FAQ says the occupancy certificate "relates to the occupation of the apartment/building, which has provision for civic infrastructure such as water, sanitation and electricity and is habitable," while the completion certificate "relates to the completion of the entire project certifying that the project has been developed according to the sanctioned plan, layout plan and specifications, as approved by the competent authority." Where a state issues a single certificate covering both, the FAQ says that "would suffice." The trade-off: an occupancy certificate tells you the building can be lived in, but only a completion certificate speaks to the whole project matching its approvals, and a buyer moving in early may hold the first without the second.

What does an occupancy certificate certify?

That the building or apartment is fit to occupy. MoHUA's FAQ says Section 2(zf) defines the occupancy certificate, and explains that it "relates to the occupation of the apartment/building, which has provision for civic infrastructure such as water, sanitation and electricity and is habitable."

The focus is on the building and its services. Water, sanitation and electricity are named, and the test is habitability. For a Bengaluru buyer, this is the certificate that speaks to whether a tower can lawfully be lived in.

What does a completion certificate certify?

That the whole project was built as approved. The FAQ says Section 2(q) defines the completion certificate, and that it "relates to the completion of the entire project certifying that the project has been developed according to the sanctioned plan, layout plan and specifications, as approved by the competent authority."

Two words matter here: "entire project." A completion certificate looks beyond one tower to the project as a whole, and it measures the result against the sanctioned plan, the layout plan and the approved specifications. In a multi-phase project, this distinction means an occupancy certificate for one tower does not by itself show that the whole project is complete.

What if a state issues only one certificate?

The FAQ says one certificate can satisfy both definitions. It notes that the definitions in Sections 2(zf) and 2(q) "are very broad and use the term by whatever name called," and concludes: "if in a State/UT only one certificate is issued which provides for both the aspects covered under the two definitions, it would suffice the requirements under the Act."

The practical point for a Bengaluru buyer is to look at what the document actually certifies rather than only at its title. A certificate called by a local name may cover habitability, completion to plan, or both. Ask the promoter, or check with the planning authority, which aspects the certificate on offer covers. Our earlier explainer on sanctioned building plan deviations in Bengaluru covers how to read the plan a completion certificate is measured against.

Who issues these certificates?

The competent authority. The FAQ says the completion certificate and occupancy certificate "are required to be issued by the competent Authority as defined under Section 2 (q) and 2 (zf) of RERA respectively." It adds that in some cases a development authority or urban local body may be both the promoter and the competent authority, and that "In such cases, the Development Authorities / Urban Local Bodies can issue the required certificates to their own projects as per the provisions of local laws."

This matters for Bengaluru buyers of flats sold by public bodies. The FAQ separately says the Act "covers all bodies (private and public) which develop real estate projects for sale to the general public," so a development authority selling flats is a promoter under the Act.

How do these certificates connect to RERA registration?

Through the completion certificate. The FAQ says that when RERA began, promoters of "all ongoing projects which have not received completion certificate" had to register within three months of the Act's commencement. It also says that under Section 3(2)(b), "registration of project is not required, where the promoter has received completion certificate for a real estate project prior to commencement of RERA."

So, for a project that began before RERA, the completion certificate decided whether the project had to be registered. A buyer looking at an older Bengaluru project that is not on the regulator's website can ask whether it received its completion certificate before RERA commenced, noting that the FAQ says Sections 3 to 19 of the Act were notified for commencement with effect from 1st May, 2017.

Should a buyer take possession without an occupancy certificate?

That is a decision to take with eyes open and, ideally, legal advice. The FAQ lists among allottees' duties under Section 19 a "responsibility to take possession," and among their rights the entitlement "to necessary documents and plans related to the property after taking possession." It does not set out a rule on possession without an occupancy certificate.

Courts and tribunals have addressed the question in specific cases. Our reports on an NCDRC ruling that a possession offer without an OC was invalid and the Karnataka appellate tribunal's view that an occupancy certificate is not a procedural formality describe two such decisions. Each turned on its own facts, so buyers should read them as illustrations rather than general rules.

The date of handover also starts a separate clock. The FAQ says that "As per section 14(2), the promoter shall be liable for 5 years form the date of handing over of possession to the allottee towards structural defect or any other defect as specified therein," and that the promoter must rectify such defects within 30 days, failing which aggrieved allottees "shall be entitled to receive appropriate compensation as provided under the Act." Recording the handover date in writing, and keeping the certificates on file with it, helps if a defect claim arises later.

Certificates are also part of the paperwork that should reach the association of allottees. The FAQ says Section 17 "provides for detailed provisions regarding transfer of title of the apartment to the allottee and the undivided proportionate title in the common areas of project to the association of the allottees," and that "it shall be the responsibility of the promoter to handover the necessary documents and plans to the association of the allottees or the competent authority, as the case may be." An association that holds the project's approvals and certificates is better placed to deal with later repairs, renewals and resale queries.

Resale buyers should ask the same questions. The FAQ says that under Section 2(d) an allottee "includes a person who acquires the said apartment / plot through transfer or sale." A Bengaluru buyer purchasing a flat from its first owner should ask the seller for copies of the certificates that were issued for the building and the project, rather than relying on a verbal assurance.

For buyers comparing completed and near-complete projects, such as Century Astoria in Jakkur, the certificate status is one of the first things to ask about, alongside the registration record on the Karnataka regulator's website.

What should a Bengaluru buyer check at handover?

1. Ask for a copy of the occupancy certificate for your tower, and check that it names your building.
2. Ask whether a completion certificate has been issued for the entire project, and if not, which phases remain.
3. Read what each certificate actually certifies, since one combined certificate may cover both aspects.
4. Confirm the issuing body is the competent authority for the project's location.
5. Match the certificate's description against the sanctioned plan and layout plan you were given.
6. Check the project's registration and quarterly updates on the Karnataka real estate regulator's website.
7. Keep copies of both certificates with your sale deed, since the FAQ says allottees are entitled to necessary documents after possession.

Frequently asked questions

What is the difference between an OC and a CC under RERA?

MoHUA's RERA FAQ says the occupancy certificate relates to occupation of the apartment or building, with civic infrastructure such as water, sanitation and electricity, and confirms it is habitable. The completion certificate relates to completion of the entire project according to the sanctioned plan, layout plan and specifications approved by the competent authority.

Is one combined certificate enough if a state issues only one?

Yes, according to MoHUA's FAQ. It says the definitions in Sections 2(zf) and 2(q) use the words by whatever name called, so if a state issues only one certificate that covers both habitability and completion according to approvals, it would suffice the requirements under the Act.

Who issues the occupancy and completion certificates?

MoHUA's FAQ says both certificates are issued by the competent authority as defined in Sections 2(q) and 2(zf) of RERA. Where a development authority or urban local body is both promoter and competent authority, it can issue the certificates to its own projects as per local laws.

Did completed projects have to register under RERA?

MoHUA's FAQ says Section 3(2)(b) exempts from registration projects where the promoter received the completion certificate before RERA commenced. Ongoing projects that had not received a completion certificate were required to register with the Regulatory Authority within three months of the Act's commencement.
