Rooftop Gardens & the DNCC 10% Tax Rebate: What Landlords Need to Know
The DNCC Rooftop Garden Tax Rebate
DNCC introduced the rooftop garden tax incentive as part of its urban greening programme. The rebate is:
- 10% reduction on annual holding tax for buildings with a qualifying rooftop garden
- Available to both residential and mixed-use buildings
- Requires annual reconfirmation (inspection or self-declaration, depending on ward)
For a building paying ৳30,000/year in holding tax, this is ৳3,000 saved annually — without any change in the building's income.
What Qualifies as a "Rooftop Garden"?
DNCC does not require a manicured botanical garden. The minimum qualification criteria (which may vary slightly by ward) typically include:
| Requirement | Details |
|---|---|
| Coverage | At least 20% of rooftop area must have living plants |
| Container depth | Minimum 6 inches of soil/growing medium |
| Species | Any food crops, ornamental plants, or trees — at least 10 distinct containers or raised beds |
| Irrigation | Regular watering evidence (functional drip system or visible watering cans/hose) |
| No structure | No new permanent structures built under the guise of a garden |
Grow bags with tomatoes, chilies, or bottle gourds count. Potted plants along the parapet count. Even a simple herb garden in recycled containers qualifies.
Beyond the Rebate: Real Benefits
Heat reduction. Rooftop greenery reduces surface temperatures by 5–10°C, directly lowering cooling costs for the top floor flat. Tenants notice.
Tenant attraction. A rooftop garden is a meaningful selling point — particularly for families. In a market where many buildings are identical, it creates differentiation.
Community building. Buildings where tenants share a rooftop garden report stronger social cohesion and fewer disputes over common areas.
Air quality. Each square metre of green space absorbs particulates. In Dhaka's air-quality context, this is a genuine benefit for residents.
How to Apply for the Rebate
1. Create the garden first. Minimum qualifying standard before applying.
2. Visit your ward DNCC office with your holding number and photos of the rooftop garden.
3. Complete the application form (available at the ward office or the DNCC website).
4. Schedule an inspection — a ward inspector will visit within 2–4 weeks.
5. Receive certification — the rebate is applied to your next holding tax bill.
The entire process takes 4–8 weeks in most wards. Some wards allow photo-based self-declaration for buildings that have already been inspected in a prior year.
Start with ten grow bags on your rooftop this weekend. The investment is under ৳2,000. The rebate and tenant goodwill pay back that investment many times over.
