A Hyderabad family we spoke to this month had keys in hand for a flat in Bachupally, boxes packed, and a shifting van booked for the weekend. Then their bank asked one question that stalled everything: where is the occupancy certificate? The tower was built, the lift worked, neighbours had already moved in, yet the document that says the building may legally be lived in had never been issued. The move was postponed, and the buyers learned an expensive lesson about a single piece of paper.

The short answer. An occupancy certificate, or OC, is the municipal sign off that a building was completed in line with its approved plan and is fit to occupy. In Telangana this now runs through the BuildNow portal at buildnow.telangana.gov.in, which replaced the older TG-bPASS system from 15 December 2025. The trade off for a buyer is convenience against safety: taking possession without an OC lets you move in sooner, but it leaves you holding a home whose legal completion is unconfirmed, which can complicate loans, resale, and municipal formalities later.

What is an occupancy certificate, and why should a Hyderabad buyer care?

An occupancy certificate is the local authority's confirmation that a finished building matches the plan it was permitted to follow, and that it is ready for people to live in. A building permission, granted before construction, only says the plan is approved. The OC, granted after construction, says the promise was actually kept. For a buyer, that difference is the whole point, because it is the OC that ties the concrete you are standing in to the drawing the authority signed off.

Care about it because it is the cleanest single signal that a project was built by the rules rather than around them. A builder who deviated from the sanctioned plan, added floors, or reduced setbacks will often struggle to obtain a clean OC, and that struggle is exactly what you want to discover before you pay, not after you have moved your family in.

Which portal issues it now, BuildNow or TG-bPASS?

BuildNow is the current portal. Telangana moved building permission, layout approval, and occupancy certificate applications for GHMC, HMDA, and DTCP areas onto buildnow.telangana.gov.in, a unified system it calls a next generation building and layout approval platform. The earlier TG-bPASS portal was wound down, with 15 December 2025 set as the cut off for that older system. If a builder or a blog still points you only to TG-bPASS, treat that as a sign the information is dated and check BuildNow instead.

The new platform runs on a self certification model, where the professionals who prepare a building's drawings take on responsibility for compliance, and the system scrutinises submissions before permissions are granted. For a buyer, the useful takeaway is not the machinery but the record it leaves behind. Every genuine approval and certificate now has a digital trail on BuildNow that you can look up, which is far stronger than relying on a laminated copy in a sales lounge.

This matters for buyers because approvals and certificates issued or tracked under the new system are what you should be verifying today. The portal is the authority's own record, so it outranks a printout a sales office hands you. If the numbers on your copy do not resolve on the portal, that mismatch is worth chasing down before any money changes hands.

Which buildings actually need an occupancy certificate?

Not every structure has to apply, but almost every flat you would buy does. On the official BuildNow portal, the exemption is narrow: an "individual residential building in plots area upto 200 Sq.m. with a height of 7.00 m" is exempted from applying for an occupancy certificate. In plain terms, only a small standalone house on a modest plot escapes the requirement. Any apartment tower, gated community, or larger independent building sits outside that exemption and is expected to obtain an OC, so its absence on a project of real size is a genuine red flag rather than a technicality.

If you are buying an independent house, check where it falls against that 200 square metre and 7 metre line. If you are buying a flat in a multi storey block, assume an OC is expected and ask to see it.

How do I check whether a Hyderabad property has its OC?

Start with the paperwork and then confirm it against the authority's own record. Ask the builder or seller for a copy of the occupancy certificate and the building permission, and note the application number. BuildNow lets citizens verify approvals: by quoting the building application number, the approved building permission copy can be downloaded from the portal, and the site offers a Citizen Search option through its main navigation. Use that to confirm that the document you were handed matches what the authority actually issued.

Because the project also has to hold up against your other checks, read the OC alongside the RERA record and your title work rather than in isolation. Our guide to verifying a Hyderabad RERA registration covers the launch and disclosure side, and for a resale flat our guide to GHMC mutation and PTIN covers the municipal records you inherit from the previous owner.

What can go wrong if I buy a flat without an OC?

The core problem is that you cannot fully prove the building is legally complete. Without an OC, the property's completion status rests on the builder's word rather than the authority's certificate, and that gap can surface at the worst moments, when you seek a home loan, when a future buyer's bank runs its checks, or when you deal with municipal and utility formalities.

The deeper risk sits in the reason an OC is sometimes missing. A clean certificate is hard to obtain when a building deviates from its sanctioned plan, so a long delayed OC can hint at extra floors, encroached setbacks, or other unapproved changes that the buyer inherits. Sorting those out later, where it is even possible, costs time and money and is squarely the seller's problem to fix before your purchase, not yours to absorb after it. That is why the presence of a valid OC is worth insisting on rather than treating as a formality to complete someday. The table below lays out how a flat with a valid OC compares against one without.

What should I ask the builder or seller for?

Ask in writing, and ask early. Request the occupancy certificate, the building permission, and the sanctioned plan, and note the BuildNow application number so you can verify each on the portal. If the OC has not yet been issued, ask for a written, dated commitment on when it will be, and hold back on final payment and possession until it lands. For a resale flat, ask the current owner for the OC that was issued when the building was completed, since it stays with the property and should pass to you.

Your OC checklist before taking possession in Hyderabad

1. Ask the builder or seller for the occupancy certificate in writing, not just verbally.
2. Collect the building permission, the sanctioned plan, and the BuildNow application number.
3. Open buildnow.telangana.gov.in and use Citizen Search to confirm the approval record.
4. Download the approved permission copy by quoting the application number and match the details.
5. For an independent house, check the 200 square metre and 7 metre exemption line.
6. Cross read the OC with the RERA record and your title and tax checks.
7. Withhold final payment and possession until the OC is issued or clearly committed in writing.

The bottom line for Hyderabad buyers

An occupancy certificate is a small document that carries a large amount of proof. It confirms that the building you are buying was finished the way the authority approved, and in Telangana you now confirm it on BuildNow rather than the retired TG-bPASS. Treat a missing OC on an apartment project as a reason to pause and ask, keep every approval with your file, and let the authority's own record, not a sales desk assurance, be the version you trust. The Bachupally family eventually got their move done, but only after the paperwork caught up with the packing.

Frequently asked questions

Is BuildNow the same as TG-bPASS?

No, BuildNow is the newer system that replaced TG-bPASS. Telangana moved building permission, layout approval, and occupancy certificate applications for GHMC, HMDA, and DTCP areas onto buildnow.telangana.gov.in, with 15 December 2025 set as the cut off for the older TG-bPASS portal, so buyers should verify approvals on BuildNow today.

Which Hyderabad buildings are exempt from needing an OC?

The official BuildNow portal exempts only an individual residential building on a plot area up to 200 square metres with a height of 7 metres from applying for an occupancy certificate. Apartment towers, gated communities, and larger independent buildings fall outside that exemption and are expected to obtain an OC.

Can I get a home loan or resell a flat without an OC?

It can be harder. A missing occupancy certificate can raise questions during a lender's or a future buyer's due diligence, because the building's legal completion is unconfirmed. Rules vary by lender and property, so confirm your bank's stance and ask the seller for the OC or the builder's completion documents before you commit.

How do I check a building's approval on BuildNow?

Use the Citizen Search option on buildnow.telangana.gov.in and quote the building application number. The portal lets you download the approved building permission copy, so you can match the document a builder gives you against the authority's own record. Ask the builder or seller for that application number up front.
