What is a density block?
A density block is a geographic area within Dhaka with a shared Area FAR cap and population density target. Under SRO 466/2025, RAJUK consolidated 275 ward-level blocks into 68 larger blocks.
Each block defines:
| Parameter | Meaning |
|---|---|
| Max Area FAR | Ceiling on development intensity for the block |
| Desirable density | Planning target (persons or units per hectare) |
| Max population density | Hard cap — now 300 persons/ha (raised from 250) |
| Gross-to-net ratio | Relationship between gross and net developable area |
Why blocks matter
Even if your road qualifies for a high Plot FAR, the Area FAR of your block may be lower. DAP always applies:
BaseFAR = MIN(PlotFAR, AreaFAR)
Sample blocks (from database)
| Code | Name | Max Area FAR | Key localities |
|---|---|---|---|
| DB-01 | Old Dhaka | 4.5 | Purana Paltan, Lalbagh, Wari |
| DB-02 | Motijheel CBD | 5.0 | Motijheel, Paltan |
| DB-04 | Dhanmondi | 3.5 | Dhanmondi, Shukrabad |
| DB-05 | Gulshan–Banani | 3.5 | Gulshan, Banani, Niketan |
| DB-09 | Uttara Model Town | 3.0 | Uttara Sectors 1–14 |
| DB-22 | Bashundhara R/A | 3.5 | Bashundhara, Baridhara |
How to find your block
- Identify your locality/ward
- Match against block locality lists (Appendix 3.6)
- Use the Regulations browser or Plot Search tools
All 68 blocks from Appendix 3.6 are transcribed in the database. See Data & methodology for the seed pipeline.
