Vietnam's 30% Foreign Ownership Cap: How to Verify If a Building Is Already Full

Vietnam's foreign ownership quota is one of the hardest rules in the market. It's not a guideline, and it's not something that can be waived. Any Sale and Purchase Agreement signed after a building's 30% quota has been reached is legally invalid — the Land Registration Office will reject the registration regardless of what the developer's sales team told you.

How the Cap Works

Under the Law on Housing 2023, foreign individuals and foreign-invested enterprises collectively cannot own more than 30% of the residential units in a single condominium building.

The word "building" is now defined more precisely by Decree 95/2024/ND-CP: where a development project contains multiple blocks sharing a common structural base or basement, the 30% cap applies individually to each block, not across the aggregate project. This resolved a common ambiguity where developers argued that the cap applied project-wide.

For landed properties — townhouses, villas, low-rise houses — the limit is 250 foreign-owned units within a single administrative ward (phường or xã). If a ward contains only one commercial housing project, the foreign cap drops further to 10% of that specific project's landed units.

There is no mechanism to appeal these caps. There is no waitlist. When a block hits 30%, it's legally closed to new foreign SPA purchases until an existing foreign owner sells their unit to another eligible foreign buyer or to a Vietnamese national (which would reduce the count).

The Real Consequences of Ignoring the Cap

If a developer's sales team tells you a unit is available and you sign an SPA, pay the deposit, and make progress payments — but the building was already at 30% — the entire transaction is voidable. Specifically:

• The Land Registration Office will refuse to register the SPA transfer
• You will not receive a Pink Book
• Your legal recourse is a civil dispute against the developer, which is slow, expensive, and uncertain
• If the developer is insolvent by the time the problem surfaces, recovery is even harder

This isn't a hypothetical. In premium HCMC developments like Empire City (Thu Thiem) and The Metropole Thu Thiem, the 30% quota was depleted within days of primary launch in some blocks. Foreign buyers who arrived late were steered toward Long-Term Lease (LTL) structures or told the quota would "open up soon" — neither of which constitutes a valid path to a Pink Book.

How to Verify Foreign Quota Before Signing

There are three steps to verify quota availability, and all three should be completed before executing any SPA.

Step 1: Request the Department of Construction clearance letter

By law, developers can only sell to foreigners after receiving written clearance from the provincial Department of Construction (Sở Xây dựng) confirming the project is eligible for foreign ownership. Request this document directly. A credible developer will produce it without hesitation. If they can't, stop the transaction.

Step 2: Audit the developer's foreign sales registry

Ask the developer to provide a certified copy of their current sales ledger showing exactly how many units have been sold to foreign nationals under SPA contracts in your specific block. Cross-reference this against the total unit count in that block. If block A has 200 units and 58 are already held by foreigners, you have room for 2 more before hitting the cap.

Developers are not always forthcoming with this data, especially in secondary market situations. Your legal counsel should request this formally in writing, creating a documented record that the developer confirmed available quota at a specific date.

Step 3: Insert a contractual indemnity clause

Even if the developer confirms available quota, your SPA should include a clause stating: if the Land Registration Office rejects the transaction due to a quota violation, the developer is contractually obligated to refund 100% of all paid capital plus interest within a specified timeframe — typically 30 business days. This doesn't prevent the problem, but it gives you enforceable recovery rights if the developer misrepresented the quota status.

Secondary Market: Foreign SPA vs. Vietnamese Owner

In the secondary market, quota availability interacts with the seller's nationality.

If you're buying from an existing foreign SPA holder, the transaction transfers their SPA status to you. The foreign unit count in the building stays the same — you're replacing one foreign owner with another. This preserves your right to a Pink Book under your own name.

If you're buying from a Vietnamese owner, you cannot structure the transaction as an SPA with title transfer rights. You must use a Long-Term Lease. The LTL doesn't give you a Pink Book, doesn't appear in the foreign quota count, and doesn't give you independent resale rights. This is why secondary market foreign SPA units trade at a 5% to 10% premium over equivalent units with Vietnamese title — that premium reflects the legal protection the SPA structure provides.

What Saturated Buildings Actually Mean for Buyers

Popular premium buildings in HCMC's Thu Thiem area (District 2 / Thu Duc City) are almost entirely quota-saturated. Buyers seeking these addresses can only enter through the secondary market, purchasing from an existing foreign SPA holder. Expect to pay above the Vietnamese owner price.

Da Nang has substantially more available quota, particularly in newer coastal and riverfront projects like Nobu Residences and Sun Cosmo. Hanoi's large integrated townships (Vinhomes Ocean Park, Vinhomes Smart City) have more inventory and generally more quota availability, though specific high-demand blocks can sell through quickly.

Phu Quoc is designated a Special Economic Zone, and the foreign quota framework applies to the condominium-type residential structures there, though much of the island's real estate consists of resort properties with different legal classifications.
