The question we hear most from agri-tech investors: “I’ve leased 30 hectares of rice land and want to build greenhouses, cold storage and a pre-processing area — can I just build?” The short answer: no. Rice land is specially protected, and every structure on it must pass through land-use-purpose conversion.
Why rice land is the hardest farmland to touch
The Land Law 31/2024/QH15 (effective 01/08/2024) continues protecting rice land for national food security. Converting rice land to other purposes — even still agricultural production but tied to structures like permanent greenhouses, cold stores or pre-processing workshops — requires permission from the competent state authority. Building on rice land without conversion is a violation, punishable by administrative fines and restoration orders (demolition).
Local practice: many provinces only allow conversion within approved planning (high-tech agricultural zones, crop-restructuring areas). Outside planning, applications are almost certainly returned.
The real four-step sequence
- Step 1 — Planning check: verify district/provincial land-use planning for convertibility. This step eliminates 80% of ineligible files.
- Step 2 — Apply for conversion permission: file with the competent land authority, attaching the post-conversion land-use plan.
- Step 3 — Financial obligations: pay land-use or land-rental differentials and statutory fees — the “hidden cost” many investors fail to budget.
- Step 4 — Register the change: update the new purpose on the certificate — only then are structures fully lawful.
Incentives for high-tech farms: real but conditional
High-tech agricultural projects may enjoy investment incentives under the Investment Law 143/2025/QH15 (effective 01/03/2026) — land-rental exemptions/reductions and tax breaks. But note the logic: incentives only arise once the project is lawful on land. Many investors build first and seek incentives later, then get stuck on “structures on unconverted land” and lose incentive eligibility entirely.
Frequently Asked Questions
1. Do temporary net houses need conversion?
It depends on permanence and local rules. Easily removable temporary structures directly serving farm production are treated more flexibly; but steel-frame greenhouses on concrete footings, cold stores and workshops definitely require conversion.
2. Is converting rice land to aquaculture easier?
It is still a purpose conversion requiring permission, though some localities encourage rice-to-aquaculture restructuring within planned zones, where procedures may be smoother than conversion to non-agricultural land.
3. Can a lessee convert leased rice land itself?
The lessee may handle procedures if lawfully authorized by the landowner and permitted by the lease. But any resulting financial obligations should allocate clearly to one party in the lease contract upfront.
