Most homebuyers check the property registration papers for the flat, but many forget to verify the documents for shared facilities like the swimming pool, lift, and community hall. A developer's brochure may promise a rooftop garden or a modern gym. However, only the official documents can prove that these facilities are approved and will actually be available for residents.
This is more common than many buyers realize. A developer shows a beautiful sample flat and an attractive list of amenities, and the buyer signs the agreement based on trust.
Later, the swimming pool is never built, the "community hall" is converted into extra apartments, or the backup generator cannot support the whole building during a power outage. Checking the right documents before you buy can help you avoid these problems.
This blog explains the most important documents you should check before buying a flat in Bangladesh. It walks you through each document step by step, so you know what to ask for at every stage of the purchase.
Bangladesh National Building Code (BNBC) sets the safety and design standards for most of these approvals. That is why a document may look official but still fail to meet the required legal and technical standards.
A reputable real estate developer keeps this documentation ready and organized because they have nothing to hide from a serious buyer.
The Master Plan: Checking Layout and Structural Approvals
Every legal residential project begins with an approved master plan. This is one of the most important documents to check before buying a flat. It protects you from developers who promise more than what the authorities have officially approved. Always ask to see the approved master plan before making your decision or getting emotionally attached to a unit.
The master plan also defines the project's Floor Area Ratio (FAR). This calculation determines how much of the land can be used for buildings and how much must remain as open space. If a developer exceeds the approved FAR to create more saleable units, they often reduce important shared spaces such as the garden, playground, or parking area to make it work.
Match the Sanctioned Layout Against Reality
The number of floors, the community spaces, and the open areas on paper must match what the developer is actually building. A building plan approval certificate from RAJUK or the relevant local authority lists these details clearly, so compare it line by line with what you see on-site or in the brochure.
Watch for Common Areas Quietly Turning into Apartments
Developers under financial pressure sometimes convert a planned community hall, gym, or lounge into two or three saleable flats. This is illegal because common areas belong jointly to every unit owner, not to the developer, once units are sold. Ask directly whether any part of the sanctioned common space has been altered from the original plan.
Request the Official Blueprints for Shared Facilities
A proper set of blueprints shows exactly where the lift, the emergency stairs, and the community hall sit within the building. This matters because verbal assurances about "a lift on every floor" mean nothing if the sanctioned drawing shows something different.
Check Environmental Compliance for Large-scale Amenities
Projects with a swimming pool, a large garden, or extensive landscaping usually need additional environmental clearance. This step protects you from amenities that get shut down later for violating environmental standards, leaving you with a dry pool and a smaller garden than promised.
Taken together, these four checks confirm one important thing. The amenities in the brochure and the amenities in the sanctioned plan turn out to be the same project, not two different versions of it.
Utility Security: Ensuring Reliable Water, Power, and Gas
A flat with beautiful amenities means little if the building cannot reliably supply water, electricity, and gas to every resident. Utility documentation tells you whether the building was designed to handle real, everyday demand.
Confirm the Building's Approved Electrical Load Capacity
The load sanctioned by the power authority must be sufficient for every flat, plus the lifts, water pumps, and common lighting running at the same time. A building that scraped through with a bare minimum load often struggles once every unit is occupied and running air conditioners.
Get Legal Proof of a Sanctioned Water Connection
Some buildings run entirely on a temporary or unauthorized deep tube well connection instead of an approved municipal or WASA supply. This kind of connection can be disconnected without notice, so ask for the sanction letter, not just a working tap.
Verify that Utility Bills are Fully Cleared
Before you take possession, confirm that the previous owner or the developer has paid off every outstanding electricity, gas, and water bill. Unpaid dues can lead to a sudden service disconnection that becomes your problem the day you move in.
Check the Technical Capacity of Backup Systems
Ask for the generator's rated capacity and compare it against the building's actual connected load, including lifts and common area lighting. A generator that only powers a few emergency lights during a load-shedding period is not the backup system many buyers assume they are getting.
Suppose a twelve-storey building runs two lifts, corridor lighting, and water pumps on backup power during an outage. If the installed generator only covers half that combined load, residents lose lift access at the exact moment they need it most, usually during the longer outages when the main grid stays down for hours.
Asking for the load calculation sheet in advance is the only way to catch this gap before you move in, rather than after.
Clarify How Gas is Actually Supplied to Your Unit
New residential connections to the piped gas network have been restricted in many parts of Bangladesh for years, so many newer buildings run on centralized LPG systems instead of individual gas lines.
Ask the developer to show you, in writing, which system your unit uses and who holds the supply contract, since this changes both your monthly cost and your dependence on the building management.
The Final Green Light: Safety and Completion Papers
This section covers the single most important document in the entire buying process. Skipping it is the fastest way to end up with a flat you cannot legally use.
The Occupancy Certificate Confirms the Building is Fit to Live in
This is the document that certifies the structure complies with local safety norms and is genuinely ready for habitation. Occupancy certificate requirements exist precisely to stop people from moving into unsafe, unfinished, or non-compliant buildings, so never treat this as a mere formality.
Municipal Authorities Issue This Only After a Physical Inspection
Local authorities check the completed structure against the originally approved plan before granting this certificate. If a developer avoids applying for it, that hesitation usually means the finished building does not fully match what was sanctioned.
Buyers often confuse the Completion Certificate with the Occupancy Certificate, but they answer two different questions. The Completion Certificate confirms the structure itself matches the approved drawings, while the Occupancy Certificate confirms the finished building is actually safe for people to live in.
A project can hold one without the other, so ask for both by name rather than accepting a single certificate as proof of everything.
High-Rise Buildings Need Proven Fire Safety Compliance
In high-rise buildings, fire hydrants, fire alarms, and emergency lighting must be fully tested and working properly. It is not enough for these systems to be installed. They must be functional and ready to use in an emergency. This is a mandatory safety requirement for tall buildings, where quick evacuation can be more difficult.
Community & Possession: Formalizing Your Amenity Rights
Getting the keys is not the finish line. This last set of documents protects the specific rights and shared responsibilities that come with your unit. The Bangladesh Apartment Ownership Act recognizes shared facilities as common property belonging to every unit owner, and the documents below are what turn that legal principle into something you can actually enforce.
Get a Dedicated Parking Allocation Document
Make sure your parking space is assigned in writing and includes a specific parking slot number linked to your apartment. Without a written parking allocation document, parking disputes are one of the most common problems among apartment owners in residential buildings.
Ask for a Clear Breakdown of Monthly Amenity Costs
Ask for a written breakdown of all monthly amenity costs before you buy. This should clearly show how much you will pay for security, waste management, and the maintenance of shared facilities. Having these costs in writing helps you avoid unexpected charges after the building's management committee begins collecting monthly fees.
In Resale Purchases, Confirm Past Contributions are Paid up
If you are buying a resale apartment, ask the seller for proof that all previous maintenance fees and contributions for shared facility repairs have been fully paid. This is important because any unpaid balance may become your responsibility after you take ownership of the flat.
Treat the Handover Document as Your Final Amenity Checklist
When you take possession of your flat, you will sign a handover document confirming that all promised amenities have been delivered and are working properly.
Before signing, inspect the swimming pool, gym, lift, community hall, and other shared facilities yourself. This is your last opportunity to report any missing or damaged amenities.
A flat purchase legal checklist that only covers ownership documents and ignores this final inspection can leave buyers facing disputes after they have already moved into the building.
Final Words
Buying a flat is easier when you treat documentation as seriously as the amenities themselves. A Non-Encumbrance Certificate protects your ownership, a Sale deed for property transfer makes that ownership legal, and every certificate covered above protects the shared spaces you were promised alongside it.
If the project sits on land developed through a Joint Venture Agreement between the landowner and the builder, ask to see it too, since it confirms the developer actually has the legal right to build and sell in that location.
Keep copies of everything covered in this blog before you sign the final sale deed, and get a lawyer to review anything you are unsure about. A few extra days spent verifying paperwork costs far less than fixing an amenity dispute after you have already moved in.
None of this needs to feel confusing when you work with a developer who keeps its paperwork transparent from day one.

Most Common FAQs on Property Registration Documents
Can I get utility connections if the developer doesn't have an Occupancy Certificate?
In most cases, no. Utility authorities are increasingly requiring an Occupancy Certificate before releasing a permanent water, electricity, or gas connection, and buildings without one often rely on temporary or informal connections that can be cut off.
Always ask the developer directly whether the certificate has been issued, since a "we will get it soon" answer is a warning sign, not a guarantee. If you are relying on a bank loan, most lenders will also hold back final disbursement until this certificate is on file.
What documents prove my ownership of a specific parking space?
A car parking allotment letter is the standard proof, and it should name your unit and a specific slot number rather than a vague reference to "assigned parking." This detail should also appear in your sale deed or its annexure, since parking disputes between neighbors are far easier to resolve when the assignment is on paper.
How do I check if the building's generator capacity is sufficient for my flat?
Ask the developer for the generator's rated capacity in kVA and compare it against the building's total connected backup load, including lifts, water pumps, and common lighting. If the developer cannot produce this calculation on request, treat that as a sign the backup system was never properly sized for full occupancy.
What happens if the developer changes the rooftop garden into a penthouse?
Common areas legally belong to all unit owners jointly once flats are sold, so converting a rooftop garden into a private penthouse without consent is not allowed. Affected buyers can raise the issue with the local building authority, and in serious cases, pursue the matter through a consumer complaint or civil court.
Keep your original sales brochure and sanctioned plan copy on hand, since these are the documents that prove what was originally promised.
Does a "Possession Letter" mean all amenities are legally verified?
No. A possession letter only confirms that physical handover of the unit has taken place, not that every amenity has been legally checked or certified. Buyers still need to separately verify documents like the Occupancy Certificate and the building plan approval before assuming everything promised is legally in place.
Is an "Allotment Letter" enough to secure rights to the community hall?
No. An allotment letter is issued early, often at booking, to confirm which unit has been reserved for you, but it does not carry the same legal weight as your sale deed or the building's declaration of common facilities.
Treat it as a booking confirmation, not final proof of your rights to shared amenities.
