CDA Building Approval Lawyer in Chittagong (Chattogram): Plans, Clearances and Disputes
A CDA building approval lawyer in Chittagong makes sure a building can be lawfully approved and stays that way. The Chattogram Development Authority tests every project on title, land use, road width and its building rules before plans are sanctioned. Sorting out those legal questions early saves months of delay and protects owners from stop-work and demolition orders later.
Key pointMost CDA refusals are decided before an architect draws a line: title, the Detailed Area Plan zone and road width set what is approvable, so a legal feasibility check should come before design.
At a glance
Approval comes in stages
Land-use clearance, special project permission for larger schemes, plan approval, construction supervision and completion are separate steps, each with its own grounds for refusal.
Six-metre road rule
Chattogram's 2008 building rules require at least a six-metre access road; owners on narrower roads must surrender land for widening.
DAP decides land use
The Detailed Area Plan fixes permitted uses and restricts building near canal banks, the most common reason for land-use clearance refusals.
Deviations are enforced
CDA has issued notices and demolished parts of buildings in Kalpalok that departed from approved designs, so build only to the sanctioned plan.
Writ relief is available
Unlawful, unreasoned or unreasonably delayed decisions can be challenged before the High Court Division under Article 102 of the Constitution.

What CDA building approval covers
A CDA building approval lawyer in Chittagong helps landowners, developers and investors get a building lawfully approved by the Chattogram Development Authority, and protects them when an approval is delayed, refused or challenged. Within CDA's planning area, almost any new building, extension or change of use needs the authority's sanction before work starts. Building without it, or departing from the approved plan, exposes the owner to stop-work orders, demolition and problems selling or financing the property.
CDA controls planning across the Chattogram metropolitan area and approves on the order of 2,000 building designs a year, according to reporting in 2023. The process is technical, but it is also legal: it turns on title, land use, road width, the Detailed Area Plan, setbacks and the conditions attached to the approval. Architects and engineers prepare the drawings; the legal questions decide whether those drawings can be approved at all.
The issue usually becomes a legal one when title is unclear, when the plot is a CDA lease with conditions, when a road is too narrow, when the land-use zone does not fit the project, when neighbours object, or when a developer and landowner disagree over who is responsible for approvals.
The legal and regulatory framework
Statutes, rules and plans
- Building Construction Act 1952: the parent statute for building control in designated areas, including the power to require sanction before construction and to act against unauthorised building.
- Chattogram metropolitan building construction rules of 2008: the detailed rules CDA applies to plan approval in the city, covering land-use clearance, road width, floor area ratio, setbacks, parking and completion. Among other things, they set a minimum access-road width of six metres for new construction and require landowners on narrower roads to surrender land for widening.
- Chattogram Development Authority Act 2018: constitutes CDA and gives it its planning and development functions across the metropolitan area.
- Detailed Area Plan (DAP): the land-use plan against which CDA tests each application. The DAP prepared in 2008, for example, restricts building close to canal banks, and many land-use clearance refusals turn on the DAP zone.
- Bangladesh National Building Code: the national technical code for structural, fire and other safety standards that approved designs must meet.
- Real Estate Development and Management Act 2010: obligations on developers who build and sell apartments, including duties linked to approvals and handover.
Plots leased from CDA itself
Where the plot sits in one of CDA's own residential areas, the authority wears two hats: it is both the planning authority and the lessor. The lease deed may restrict use, fix a construction deadline and require the lessee to be recorded in CDA's file before plans are approved. A CDA building approval lawyer in Chittagong therefore checks the estate file and the planning file together, because a lessee record that has not been updated after a sale or inheritance can hold up an otherwise compliant design.
Other agencies that can be involved
Depending on the size, height and use of the building, approvals or no-objection certificates may also be needed from the fire service, the Department of Environment (see our environmental clearance practice), the civil aviation authority for tall buildings near the airport flight path, utility providers and, for plots leased from CDA itself, the authority's estate side. The Chattogram City Corporation (CCC) records the completed building for holding tax.
The approval stages at a glance
CDA approval is not a single permit. It is a sequence, and each stage can be refused for different reasons. The table below summarises the stages a CDA building approval lawyer in Chittagong plans around.
| Stage | What CDA decides | Legal issues that typically arise |
|---|---|---|
| Land-use clearance | Whether the proposed use fits the plan for that location | DAP zoning, canal and water-body setbacks, road width, ownership proof |
| Special project permission | For larger or special buildings, whether the project may proceed | Scale, traffic and utility impact, other agencies' clearances |
| Building plan (design) approval | Whether the drawings comply with the building rules | Floor area ratio, coverage, setbacks, parking, road surrender |
| Construction and supervision | Whether work follows the approved plan | Deviations, stop-work notices, neighbour complaints |
| Completion and occupancy | Whether the finished building matches the approval | Unauthorised floors, changed use, sale and financing of units |
In 2019 CDA announced targets to shorten the first three stages, which had each been allowed up to 45 days, and to move applications online with SMS verification. Actual timing still depends heavily on the completeness of the file and on whether any legal issue is raised.
Rules that most often decide an application
Road width and land surrender
Under the 2008 rules, construction is not permitted beside a road narrower than six metres unless the owner surrenders the land needed, measured from the centre of the road, to bring it to that width. Land given up for road widening passes to CDA. In 2023 CDA proposed tying permitted height to road width for buildings on narrow lanes, a change that was reported as awaiting ministry approval. Check the current position before you buy a plot on a narrow road, because it can reduce the number of storeys you can build.
Floor area ratio, coverage and setbacks
The permitted floor area is calculated by multiplying the plot area by the floor area ratio that applies to it, so height and the number of units depend on plot size, road width and the zone. Ground coverage is capped and setbacks must be left open. Developers sometimes promise landowners more floors than the rules allow; a CDA building approval lawyer in Chittagong checks the arithmetic before a joint venture agreement fixes the sharing ratio.
Parking, ground floors and change of use
Approved plans normally fix the use of each floor, including parking at ground or basement level. Converting approved parking into shops, or a residential building into offices, is a change of use that needs fresh approval. These conversions are attractive commercially but they are a frequent trigger for enforcement and for disputes among flat owners, who may be left without the parking they paid for.
Land-use zone, canals and hills
A plot zoned for one use cannot simply be built on for another. Sites near canals, water bodies and hills raise particular problems in Chattogram: the DAP restricts construction close to canal banks, and hill cutting raises separate environmental issues. These constraints are the most common reason for refusal of land-use clearance.
Step by step: from title check to occupancy
- Confirm title and boundaries. Verify the deed chain, khatians and mutation, and for CDA lease plots the authority's lessee record. A defective title is the most avoidable cause of refusal; our title verification team handles this.
- Check zoning and road width. Test the plot against the DAP and the road-width rules before design work starts, and decide whether land must be surrendered.
- Apply for land-use clearance. File the application with ownership documents, location maps and the proposed use, and respond promptly to queries.
- Obtain other clearances. Where the project size or location requires it, secure special project permission and the fire, environmental, aviation or utility clearances.
- Submit the building plan. Lodge architectural and structural drawings prepared and signed by qualified professionals, with the fees and undertakings required.
- Build to the approved plan. Display the approval on site, keep records, and obtain revised approval before making changes.
- Complete and record. Apply for completion or occupancy certification where required, register the building with CCC for holding tax, and keep the approval file for buyers and lenders.
Documents and evidence
- Registered title deeds and the chain of earlier deeds, with the latest khatian from the DLRMS land records portal and the mutation (namjari) record from the e-mutation system.
- For CDA lease plots, the allotment letter, lease deed and CDA's record of the current lessee; our CDA plot practice deals with gaps.
- Land development tax receipts from the online land tax system and a mouza map or survey plan showing the dag number and boundaries.
- For developer projects, the registered landowner-developer agreement and any registered power of attorney to the developer.
- Architectural, structural and services drawings with the professionals' details.
- Any no-objection certificates required for the project, and the land surrender deed where road widening applies.
- Identity and company documents for the applicant, and board resolutions for corporate owners.

Risks and common mistakes
Starting work before approval, or on an expired approval
Starting foundations while an application is pending is common and risky. CDA can issue stop-work notices and, for serious breaches, order demolition of the unauthorised part. Lenders and buyers increasingly ask for the approval file, so an unapproved start can also block finance and sales. If time pressure is real, the better route is to resolve the outstanding issue with the authority rather than build first and seek regularisation later, which is uncertain and can be expensive.
Building beyond the approved plan
Extra floors, enclosed setbacks and parking converted to shops are the commonest deviations. They are also the most visible. In Kalpalok, CDA issued notices to dozens of owners in 2019 and demolished parts of ten buildings in 2023 for departures from approved designs. Deviations also give buyers and neighbours grounds to sue. If the design must change, apply for a revised approval before building.
Weak or disputed title
CDA expects ownership documents that support the application. Where co-heirs have not joined, where a khatian names someone else, or where a CDA lease plot has not been recorded in the applicant's name, the application can stall or the approval can later be attacked. A neighbour or relative who disputes title may also seek an injunction against construction. Clean the title first; it is cheaper than defending a half-built project.
Joint venture agreements that ignore the rules
Landowner-developer agreements often fix the share of flats on the assumption of a certain number of floors. If CDA approves fewer, the deal unravels. Agreements should say who obtains approvals, by when, what happens if approval is refused or reduced, and who bears penalties for deviations. Our real estate development team negotiates these terms, and our guide to landowner-developer agreements explains them.
Using intermediaries who promise shortcuts
Reporting on CDA has described complaints of harassment during approvals, and stakeholders have warned that discretionary rules create room for corruption. Do not pay anyone to "fix" an approval. Keep every application, acknowledgement and query in writing, respond formally, and escalate through lawful channels if a file is delayed without reason. An unlawfully obtained approval is vulnerable to later cancellation.
Refusals, delays and enforcement action
When CDA refuses or sits on an application, the first step is to find out exactly why, in writing. Many refusals can be cured by amending the drawings, surrendering land for road widening, producing better title evidence or obtaining a missing clearance. A focused written response, prepared by a CDA building approval lawyer in Chittagong together with the project architect, often resolves the matter without litigation.
Where the authority acts without lawful authority, applies the wrong rule, gives no reasons or ignores an application for an unreasonable time, the High Court Division can be asked to intervene by a writ petition under Article 102 of the Constitution; see our writ practice. Enforcement notices and demolition orders should be answered immediately, because the window to respond and to seek interim protection is short.
Neighbours and third-party challenges
Approval does not end the legal risk. Neighbours may complain that setbacks have been encroached, that excavation has damaged their walls, or that a building blocks access, and relatives who dispute title may sue to stop construction. These claims are usually brought as civil suits seeking declarations and injunctions in the Chattogram civil courts, sometimes alongside complaints to CDA. A CDA building approval lawyer in Chittagong prepares the owner's file in advance: approved drawings, survey plans, notices to neighbours and records of excavation safeguards, so that an application for an interim injunction can be answered on the evidence within days.
Equally, if you are the neighbour, act early. Courts are more willing to restrain construction before the structure rises than to order demolition of a finished building. Our civil litigation team handles both sides of these disputes, and the High Court Division's judgments on building control are published on the Supreme Court website.
Most approval problems in Chattogram are legal problems in disguise: title, zoning and road width decide the file long before the drawings are read.
Commission a short legal feasibility note before paying for full drawings. It should confirm title, the DAP zone, road width, any land to be surrendered and the realistic floor area, so the design brief reflects what CDA can actually approve.
Overseas owners, investors and developers
Many Chattogram plots belong to families living in the UK, the Gulf or Singapore, who commission a building through a relative or a developer. Distance makes it harder to see deviations or to respond to notices on time. Overseas owners should keep the approval file under their own control, give carefully limited powers of attorney, and require the developer to report on approvals and inspections. Our NRB property practice supports owners abroad.
Foreign and corporate investors building factories, warehouses or offices outside the export processing and economic zones also come through CDA's process. TRW & Co's Chattogram advocates work alongside our Dhaka, Singapore, Dubai and London offices so that board approvals, financing and approvals run on one timetable.
For industrial and commercial buildings, the approval file often matters to more than the authority. Buyers' compliance auditors, insurers and banks may ask for the approved plan, the fire and environmental clearances and proof that the building as constructed matches what was sanctioned. Gaps discovered at that stage can delay a loan disbursement or a buyer's onboarding, so a CDA building approval lawyer in Chittagong should review the file before construction finishes rather than after.

- For a CDA lease plot, does CDA's file show you as lessee, and are lease conditions met?
- What does the DAP allow on this plot, and is it near a canal, water body or hill?
- Is the access road at least six metres, or must land be surrendered?
- Has the realistic floor area been calculated before any joint venture ratio is agreed?
- Which other clearances does the project need, and who is obtaining them?
- Is there a written plan to keep construction within the approved drawings?
- Who will apply for completion and register the building for holding tax?

Frequently asked questions
01Do I need CDA approval for a small house in Chattogram?
In CDA's planning area, generally yes. The building rules apply to new buildings, extensions and changes of use, not only to large projects. Smaller buildings follow a simpler path than special projects, but you still need land-use clearance and an approved plan before construction starts. Building without approval exposes you to stop-work orders, possible demolition of unauthorised parts, and difficulty selling or mortgaging the property later.
02How long does CDA building approval take?
It depends on the size of the project and the quality of the file. In 2019 CDA announced targets to shorten land-use clearance, special project permission and plan approval, each of which had previously been allowed up to 45 days, and moved applications online. In practice, delays usually come from title gaps, zoning problems, road-width issues or missing clearances. A legal feasibility check before applying is the most reliable way to shorten the timeline.
03My plot is on a narrow lane. Can I still build?
Possibly, but with conditions. Under the 2008 Chattogram building rules, construction beside a road narrower than six metres requires the owner to surrender the land needed to widen the road to that width, and the surrendered strip passes to CDA. In 2023 CDA also proposed linking permitted height to road width for narrow lanes, reported as awaiting ministry approval. A CDA building approval lawyer in Chittagong should confirm the current rule before you buy or agree a development deal.
04CDA refused my land-use clearance. What can I do?
First obtain the reasons in writing. Many refusals turn on the Detailed Area Plan zone, proximity to a canal or water body, road width or ownership documents, and some can be cured by amending the proposal or supplying better evidence. If the refusal is unlawful, unreasoned or based on the wrong rule, you may be able to seek review within the authority and, failing that, bring a writ petition before the High Court Division.
05We received a stop-work or demolition notice. How quickly must we act?
Immediately. These notices carry short deadlines, and the chance to respond, regularise or seek interim protection from a court can be lost within days. Stop work if the notice requires it, gather the approval file, drawings and correspondence, and have the notice reviewed by a lawyer the same week. Where the authority is acting without lawful basis, the High Court Division or the civil court can be asked for interim relief.
06Who is responsible for approvals in a landowner-developer deal?
Whatever the agreement says, so it must say it clearly. Most agreements put the developer in charge of obtaining CDA and other approvals, with the landowner providing title documents and signing applications. The agreement should also deal with refusal, approval of fewer floors than expected, delays, deviations and penalties. Without these terms, disputes over sharing ratios and handover are almost certain.
07As a flat buyer, how do I check that a building is approved?
Ask the developer for the CDA approval letter and the approved drawings, compare the number of floors and the use of the ground floor with what has been built, and check whether completion or occupancy steps have been taken. The Real Estate Development and Management Act 2010 places duties on developers, but checking before you pay is far easier than suing afterwards. Our flat purchase team can review the file for you.
