Short answer
What is the difference between a completion certificate and an occupancy certificate? A completion certificate says the building was built as per the approved plan. An occupancy certificate is the authority's permission to live in or use it. Some places issue one combined completion-cum-occupancy certificate; in others the architect certifies completion and the authority grants occupancy. Either way, apply when the house is finished and before you move in, and usually expect an inspection.

When your house is finished, there is one more approval to get: the completion certificate, the occupancy certificate, or a single certificate that does both. Banks, electricity and water boards and future buyers may ask for it. This page explains what each certificate means, why the names differ from city to city, what the application usually needs, what the inspection looks for, and what the certificate affects. It gives no fees and no time limits, because each authority sets its own. It is general information, not legal advice.
What is the difference?
The national real estate law, the RERA Act 2016, defines both terms, while leaving the details to local laws:
- A completion certificate certifies that the building “has been developed according to the sanctioned plan, layout plan and specifications”.
- An occupancy certificate is a certificate “permitting occupation of any building”, which has provision for civic infrastructure such as water, sanitation and electricity.
Both definitions say “or such other certificate by whatever name called”, because each state names them differently.
In plain words: the completion certificate says the house matches the approved plan; the occupancy certificate says you may live in or use it.
Is it one certificate or two?
It depends on where you build:
| Where | How it works |
|---|---|
| Model Building Bye-Laws 2016 (MoHUA) | One document: the authority issues a “Completion-cum-Occupancy Certificate” |
| Delhi (UBBL 2016) | One document: the Occupancy-cum-Completion Certificate (OCC) |
| Maharashtra (UDCPR 2020, outside Mumbai and some other areas) | Two steps: your architect or licensed engineer furnishes a building completion certificate to the authority; the authority inspects and issues the occupancy certificate |
| Tamil Nadu (TNCDBR 2019) | The authority issues a Completion Certificate before service connections; some smaller residential buildings are outside this rule |
RERA itself says a promoter must obtain “the completion certificate or the occupancy certificate, or both, as applicable”. Ask your local authority which it issues. RERA’s duties apply to promoters who build to sell, not to an owner building a house for their own use; your own house falls under your local building rules.
How do you get it for your own house?
The details vary, but the usual steps under the model bye-laws, Delhi and Maharashtra rules are:
- Finish the house to the approved plan. Any change from the plan should have been approved before it was built. Delhi’s rules list the minimum work needed, such as flooring, electrical wiring, plumbing in at least one toilet and the kitchen, and a lockable building; internal or external finishing and plaster are not required for the certificate.
- Your architect or engineer files the notice of completion, usually online, with the documents your authority asks for.
- The authority, or for some small houses your own professional, inspects the house against the approved plan.
- The certificate is issued, or objections are given with reasons. You fix the objections and apply again.
Which documents are usually needed?
From the model bye-laws, Delhi’s bye-laws and Maharashtra’s rules, these come up again and again:
| Document | Notes |
|---|---|
| Notice or application of completion | Filed through the architect or engineer who supervised the work |
| As-built or completion drawings | The plans as actually built, not just as approved |
| Structural stability certificate | Signed by a structural engineer, where your authority asks for it |
| Photographs of the building | From different sides |
| Inspection reports | Copies of the authority’s inspection reports |
| NOCs (fire, lift and others) | Only where your building needs them; the model bye-laws exempt residential proposals other than group housing from the fire clearance for occupancy |
Small houses on fast-track routes may need only a completion intimation. Delhi’s SARAL scheme, for example, lets the owner start occupancy after filing an intimation of completion with plans signed by an architect or engineer, and Maharashtra’s low-risk route asks the owner to intimate occupation to the authority.
What does the certificate affect?
- Moving in. Delhi’s bye-laws say no one shall occupy a building until the OCC is granted, and Maharashtra’s commencement certificate carries a similar condition. Check your own authority’s rule.
- Water, sewer and electricity. The model bye-laws say no connection to municipal water mains or sewers should be made without the completion/occupancy certificate, and temporary construction connections should not continue without it. The Supreme Court in December 2024 directed that electricity, water and sewerage connections be given only after the completion/occupation certificate is produced. Some state rules exempt certain small houses; Tamil Nadu’s rules, for example, leave some smaller residential buildings outside the completion-certificate rule. Check your state’s current rule.
- Home loans. The Supreme Court also directed banks and financial institutions to lend against a building only after verifying its completion/occupation certificate.
- Deviations. The court directed that the certificate be issued after inspection, and deferred until any deviation from the approved plan is fully corrected. So an extra room or floor built without approval can hold up the certificate.
If you need a change during construction, get a revised plan approved before you build it.
Can I get a part certificate?
Sometimes. The model bye-laws allow a part completion or occupancy certificate for an independent block, and say that for a residential house it may be issued for an independent floor. Maharashtra’s rules also allow a part occupancy certificate with conditions. Whether your authority does this depends on its rules.
What mistakes should I avoid?
These come from the rules above and from site practice:
- Moving in before the certificate or the completion intimation your route needs.
- Building something not on the approved plan, then finding it blocks the certificate.
- Losing the approved plan, as-built drawings, notice of completion and the certificate itself. Keep them together for resale, loans and future additions.
- Buying a resale house without seeing its certificate, or without checking that it covers every floor actually built (practice).
- Assuming another state’s exemption applies to you.
Frequently asked questions
Is an occupancy certificate needed for an independent house?
In many places, yes. The model bye-laws and Delhi’s bye-laws require the certificate before occupation, and the Supreme Court has linked utility connections and loans to it. Some states exempt certain small houses (Tamil Nadu, for example) or replace the certificate with an intimation (Delhi’s SARAL scheme, Maharashtra’s low-risk route). Ask your local authority.
Which comes first, completion or occupancy certificate?
Where they are separate, as in Maharashtra, the completion certificate from your architect or engineer comes first and the authority then issues the occupancy certificate. Where there is one combined certificate, as in Delhi, you get both together.
Can I get an electricity connection without an occupancy certificate?
The Supreme Court directed in 2024 that service connections be given only after the completion/occupation certificate. Some state rules, such as Tamil Nadu’s, exempt certain smaller houses. Check with your electricity board and local authority.
Can I get a home loan without an occupancy certificate?
The Supreme Court directed banks and financial institutions to lend against a building only after verifying its completion/occupation certificate. Ask your bank what it needs.
Who issues the completion certificate?
Your local authority, such as the municipal body or development authority that approved the plan. In some systems, such as Maharashtra’s, your architect or engineer furnishes the completion certificate and the authority issues the occupancy certificate.
