Commencement, Completion, Occupancy: Three RERA Certificates a Bengaluru Buyer Should Check
The RERA Act defines the commencement certificate in Section 2(m), the completion certificate in Section 2(q) and the occupancy certificate in Section 2(zf). This guide explains what each permits, where it appears in registration and quarterly updates, and which buyer and builder clocks start after the occupancy certificate.
A Bengaluru buyer weighing two projects on the same road may hear three different reassurances in one weekend. One sales team says its tower has its commencement certificate. Another says completion is around the corner. A third says the occupancy certificate is expected soon. They sound like stages of the same thing, and in a sense they are. But each certificate means something different, each is issued at a different point, and each changes what a buyer can expect next.
The Real Estate (Regulation and Development) Act, 2016 defines all three. This guide sets the definitions side by side, explains where each one shows up in a project's paperwork, and suggests how a buyer can match them to the stage a project claims to be at.
The short answer. Section 2(m) defines the commencement certificate as the permission issued by the competent authority to allow the promoter to begin development works as per the sanctioned plan. Section 2(q) defines the completion certificate as the certificate certifying that the project has been developed according to the sanctioned plan, layout plan and specifications. Section 2(zf) defines the occupancy certificate as the certificate permitting occupation of a building, which has provision for civic infrastructure such as water, sanitation and electricity. Section 4(2)(c) requires the commencement certificate to be filed at registration, and Section 11(4)(b) makes the promoter responsible for obtaining the completion or occupancy certificate and making it available. The trade-off: each certificate reduces a particular risk, but none of them on its own tells you a flat is ready for you to live in and own.
What does each certificate mean under RERA?
Three permissions at three moments. In the text of the Act published by the Telangana regulator, Section 2(m) says a commencement certificate means the commencement certificate or the building permit or the construction permit, by whatever name called, issued by the competent authority to allow or permit the promoter to begin development works on an immovable property, as per the sanctioned plan.
Section 2(q) says a completion certificate means the completion certificate, or such other certificate, by whatever name called, issued by the competent authority 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.
Section 2(zf) says an occupancy certificate means the occupancy certificate, or such other 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.
The repeated phrase "by whatever name called" is worth noticing. The Act defines these by what they do, not by the label on the document. A Bengaluru buyer should look at what the competent authority actually issued and what it permits, rather than rely on the name a brochure uses.
| Certificate | What it permits or certifies | Where it matters under the Act |
|---|---|---|
| Commencement certificate | Permission to begin development works as per the sanctioned plan | Filed with the registration application, Section 4(2)(c) |
| Completion certificate | Certifies the project was developed per sanctioned plan, layout plan and specifications | Promoter to obtain and make available, Section 11(4)(b) |
| Occupancy certificate | Permits occupation, with civic infrastructure such as water, sanitation and electricity | Starts the allottee's two months to take possession, Section 19(10) |
| Pending approvals after commencement | Not a certificate, but a disclosure | Quarterly list of approvals taken and pending, Section 11(1)(d) |
| Conveyance after occupancy | Not a certificate, but a deadline | Within three months of the occupancy certificate where no local law applies, Section 17(1) |
Where does the commencement certificate show up?
At registration, and then in the quarterly updates. Section 4(2)(c) requires the promoter to enclose with its registration application an authenticated copy of the approvals and commencement certificate from the competent authority obtained in accordance with the laws applicable to the project, and where the project is developed in phases, an authenticated copy of the approvals and commencement certificate for each phase.
That last part matters in large Bengaluru layouts and townships. The Explanation to Section 3 says that where a project is developed in phases, every phase shall be considered a standalone real estate project, and the promoter shall obtain registration for each phase separately. So a buyer in phase three should look for phase three's commencement certificate, not phase one's.
After registration, Section 11(1)(d) requires the promoter's web page on the Authority's website to show, quarterly, an up-to-date list of approvals taken and approvals pending subsequent to the commencement certificate. Section 4(2)(l)(E) requires the promoter's affidavit to declare that it shall take all the pending approvals on time from the competent authorities. Together these give a buyer a running view of what is still outstanding between the commencement certificate and the end of the project.
Can a builder take bookings before the commencement certificate?
Not in a project that needs registration. Section 3(1) says no promoter shall advertise, market, book, sell or offer for sale, or invite persons to purchase in any manner, any plot, apartment or building in a real estate project in a planning area without registering the project with the Real Estate Regulatory Authority. And Section 4(2)(c) requires the registration application to enclose the authenticated approvals and commencement certificate.
Read together, a booking pitch for a project with no registration number is a warning sign, whatever is said about permissions being in progress. A buyer who is offered an expression of interest or a soft booking before registration should ask for the registration number and the commencement certificate before paying anything, and check both on the regulator's website.
Why does the completion certificate matter so much?
Because the Act uses it as a line. The first proviso to Section 3(1) says that projects which were ongoing on the date of commencement of the Act, and for which the completion certificate had not been issued, had to apply for registration within three months of that date. Section 3(2)(b) says registration is not required where the promoter received the completion certificate for a project before the commencement of the Act. Our earlier report on ongoing projects and the completion certificate explains that dividing line in detail.
For a project under construction today, the completion certificate is also the document that certifies the project matches what was sanctioned. Section 14(1) requires the project to be developed and completed in accordance with the sanctioned plans, layout plans and specifications approved by the competent authorities. Section 11(4)(b) says the promoter shall be responsible to obtain the completion certificate or the occupancy certificate, or both, as applicable, from the relevant competent authority as per local laws, and to make it available to the allottees individually or to the association of allottees.
The words "or both, as applicable" mean the Act leaves it to local law which certificate a building needs. That is a reason to ask the builder which certificate or certificates its project requires under the local rules, and when it expects each.
What changes once the occupancy certificate is issued?
Several clocks start. Section 19(10) says every allottee shall take physical possession within two months of the occupancy certificate issued for the apartment. Section 17(1) says the promoter shall execute a registered conveyance deed within the period under local laws, and its proviso says that in the absence of any local law, within three months from the date of issue of the occupancy certificate. Section 17(2) says the promoter shall hand over the necessary documents and plans, including common areas, to the association, and in the absence of a local law, within thirty days after obtaining the occupancy certificate.
The definition itself is also a checklist. Because Section 2(zf) speaks of a certificate permitting occupation of a building which has provision for civic infrastructure such as water, sanitation and electricity, a buyer inspecting a flat after the certificate can check that those services are in place. Our report on occupancy and completion certificates and possession covers the possession stage.
How should a buyer match certificates to a project's stage?
Ask for documents, not descriptions. In a project such as Prestige Avon on Thanisandra Main Road, or any other, the same set of questions applies.
- If the project is under construction, find the commencement certificate filed under Section 4(2)(c) on the regulator's project page.
- For a phased project, confirm the certificate and registration cover your phase, since each phase is a standalone project.
- Read the quarterly list of approvals taken and pending under Section 11(1)(d), and note anything still outstanding.
- Ask the builder which certificate the project needs under local law, completion, occupancy or both, as Section 11(4)(b) puts it.
- When told a certificate has been issued, ask for a copy and its issue date, because Section 11(4)(b) says it must be made available.
- After the occupancy certificate, note the two-month possession window under Section 19(10) and check water, sanitation and electricity.
- Track the conveyance deed and handover of documents under Section 17 from the occupancy certificate date.
