In Chattogram, building plans within the metropolitan area are approved by the Chittagong Development Authority (CDA). A complete, correct application is the fastest way to approval. Requirements are updated from time to time, so always confirm the latest rules with the authority — but the overall process looks like this.
Step 1: Get your land documents in order
Ownership deeds, mutation (namjari), up-to-date land tax receipts and the plot's mouza map are the foundation of any application. Any mismatch in names or measurements causes delays.
Step 2: Survey the plot
A precise digital survey confirms boundaries, area and road width — all of which affect how much you are allowed to build.
Step 3: Soil investigation
A soil test report supports the foundation design and is usually needed for multi-storey buildings. Read why soil testing matters.
Step 4: Architectural and structural drawings
Drawings prepared and signed by registered professionals are the heart of the application: architectural drawings that respect setbacks, floor-area rules and height limits, and structural design that follows BNBC 2020, including earthquake resistance.
Step 5: Land-use clearance and other no-objection certificates
Depending on size, location and use, you may need land-use clearance and NOCs from other agencies (for example fire service for taller buildings). Plan time for these.
Step 6: Submit, follow up and respond quickly
After submission, authorities may ask for corrections. Quick, accurate responses keep the file moving.
