Occupation Certificate and Completion Certificate: A Buyer's Guide

When you buy a ready-to-move home, two documents come up again and again: the occupation certificate (OC, often called the occupancy certificate) and the completion certificate (CC). Buyers often treat them as interchangeable. They are not. This guide explains what each confirms, how they work in Haryana and Gurgaon (Gurugram), how to check them and what to do if one is missing.

Terminology and procedures differ between states and authorities, so always check the rules that apply to your specific property.

What each certificate confirms

The order in which these are issued varies by authority and project type. Do not assume that one automatically implies the other – ask for both where relevant.

How it works in Haryana and Gurgaon

Group housing and licensed colonies

For group housing towers and buildings in colonies licensed by the Department of Town and Country Planning (DTCP), the occupation certificate is issued by the competent authority under the Haryana Building Code after inspection and the required clearances (for example, fire and structural safety). Developers frequently obtain OCs tower by tower. The completion certificate for a licensed colony relates to the colony's internal development works and is linked to licence conditions. Part-completion certificates are also used. Our guide to OC, CC and part-completion in Gurgaon explains how these fit together.

HSVP plots

For houses built on HSVP (formerly HUDA) plots, the owner applies for an occupation certificate after construction under the sanctioned building plan. See our HSVP occupation certificate guide for residential plots.

Municipal areas

For buildings in areas under the Municipal Corporation of Gurugram's building control, building plan and occupation procedures follow municipal processes. Our guide to MCG building plans and unauthorised construction covers what buyers should check.

RERA link

Under the RERA Act, 2016, the promoter must obtain the completion or occupancy certificate and make it available to allottees, and many project milestones – such as possession and formation of the association – are tied to it. HRERA project pages often carry uploaded OC documents.

Why the OC matters so much for buyers

• Lawful occupation. Occupying a building without an OC can expose occupants and owners to action by the authority.
• Utility connections. Permanent water, sewer and electricity connections are commonly linked to the OC; temporary connections can be costly and uncertain.
• Home loans and resale. Lenders typically examine the OC for ready properties, and future buyers will ask for it.
• Conveyance. Registration of the conveyance deed for a completed unit generally follows OC.

How to check the OC and CC

1. Ask the developer or seller for copies and read the tower numbers, floors and dates – the OC may cover only some towers.
2. Check the HRERA project page for uploaded OCs and the latest quarterly progress report.
3. Verify with the issuing authority (DTCP, HSVP or MCG) where possible, since copies can be outdated or incomplete.
4. Match the unit – make sure your tower, floor and unit are covered, and that the building matches the sanctioned plan (no extra floors or converted stilts).
5. Get a lawyer's review before you pay a significant amount on a ready-to-move or resale property.

What if the OC or CC is missing?

• New project, still under construction: This is normal; the OC comes at the end. Track progress on HRERA and make sure the agreement for sale ties possession to OC.
• "Ready" project offered without OC: Ask why, when the application was filed and what is pending. Consider the risk of delays to utilities, loans and conveyance. Do not accept "fit-out possession" without understanding the legal position.
• Resale flat in a building without OC: Be cautious – resale, loans and registration may be harder. Take legal advice.
• Builder floor with extra or altered floors: Check that every floor you are buying is covered by the sanctioned plan and OC.

Frequently asked questions

Is an occupation certificate the same as an occupancy certificate?

Yes. In Haryana the official term is usually occupation certificate; occupancy certificate is the common name used elsewhere. Both refer to the certificate that a building is fit to be occupied.

Can I take possession of a flat before the OC is issued?

Some developers offer early or fit-out possession, but occupying without an OC can create legal and utility problems. Take legal advice and check what your agreement for sale says.

Does every tower in a project get its OC at the same time?

Not necessarily. In Gurgaon, OCs are often issued tower by tower or for parts of a project, so check that your specific tower and floor are covered.

Where can I see a project's OC in Gurgaon?

Ask the developer for a copy, check the HRERA project page for uploaded documents and, where possible, verify with the issuing authority.
