Condominium Reserve
What is Reserve Fund Allocation in Thailand?
The Definition
In Thailand, the Reserve Fund Allocation—commonly known as the sinking fund—is a mandatory one-time contribution by buyers of new condominium units to a shared reserve for major future repairs, replacements, and upgrades like elevators, structural work, or repainting. It is calculated per square meter of the unit's living area (typically 200-500 THB/sqm) and paid upfront at purchase, managed by the condominium juristic person in a dedicated bank account. The fund remains with the building upon resale and requires 3/4 majority approval from co-owners for use or replenishment.
Global Expectations vs. Thai Reality
Western buyers might expect a refundable deposit or ongoing annual contributions prorated like in Europe (e.g., 10% of annual budget per Portugal's rules), but in Thailand, it's a non-refundable one-time payment for new units only, locked in a separate account without personal refunds even on sale. Management is strictly by the juristic person with assembly oversight, contrasting looser HOA flexibility abroad, and lacks developer guarantees beyond initial setup. Replenishment calls can surprise owners if not budgeted, unlike predictable Western sinking fund accruals.
The Problem It Presents
Buyers of new condos face an unexpected upfront cost (e.g., 50,000-200,000 THB) on top of purchase price, which isn't refunded on resale, eroding net proceeds. Resale buyers might assume no payment is needed but could face surprise replenishment calls via 3/4 vote, straining budgets. Poor management or lack of transparency can lead to funds being depleted without oversight, forcing special assessments.
Foreigner vs. Thai Citizen Rules
The sinking fund applies identically to foreigners and Thai citizens owning condo units, as it's tied to unit size share regardless of nationality. Foreigners face the same contribution on new purchases but must ensure overall building foreign quota (49% of saleable area) allows ownership, verified at the Land Office; no differential treatment on fund allocation itself.
The Thai Legal Context
Governed by the Condominium Act B.E. 2522 (1979, as amended), which mandates establishment of the sinking fund for all registered condominiums, with contributions based on unit size ratios registered in the project's Rules and By-laws at the Land Department (Department of Lands). Increases or emergency uses require 3/4 majority vote at a general meeting of co-owners, with regulations filed at the local Land Office; the juristic person oversees a separate bank account for transparency.
Benefits & Risks
Advantages
- Funds major repairs proactively, preventing sudden special levies and preserving property value long-term.
- Ensures structural integrity via collective pool, with legal safeguards like dedicated accounts and assembly approval.
- Non-refundable nature builds lasting reserves for all co-owners' benefit.
Risks & Disadvantages
- High initial outlay for new buyers with no personal return on resale.
- Vulnerability to mismanagement or unapproved uses without strong juristic oversight.
- Replenishment votes can impose unequal burdens if not all owners participate.
Showcase: How It Works
Let’s look at a real-world scenario to understand how Reserve Fund Allocation is applied during a property transaction.
The Scenario
- Mr. Smith buys a new 50 sqm studio condo in Phuket for 3,000,000 THB in 2026.
- At transfer, he pays a sinking fund of 400 THB/sqm, totaling 20,000 THB into the juristic person's dedicated account.
- Five years later, co-owners vote 3/4 to replenish 10% of the depleted fund; his prorated share is 2,000 THB.
The Result
The initial payment was non-refundable and set aside for major works. The later top-up ensured funds for specific needs like elevator replacement without requiring individual loans or special assessments.
Outcome: Initial 20,000 THB (one-time) + 2,000 THB Top-up = 22,000 THB Total Contribution
Reserve Fund Allocation vs. Monthly Maintenance Fees
A quick breakdown of how this term compares to its closest alternative.
| Feature | Reserve Fund Allocation | Monthly Maintenance Fees |
|---|---|---|
| Purpose | Major repairs/replacements | Ongoing daily operations |
| Payment Timing | One-time upfront (new buys) + rare top-ups | Monthly recurring per sqm |
| Refundability | Non-refundable, requires 3/4 vote | Adjustable annually via majority vote |
Frequently Asked Questions
Is the sinking fund required for resale condos?
No, typically original buyers pay upfront; resale purchasers inherit the fund benefit but may face proportional replenishments via vote if the fund is low.
How is the sinking fund amount calculated?
Typically 200-500 THB per sqm of living area for new units, set in project rules and registered at the Land Office.
Can foreigners contribute to the sinking fund?
Yes, same as Thais—it is unit-based. However, foreigners must confirm the 49% foreign quota allows ownership first at the Land Department.
What if the fund runs out?
Co-owners must vote (3/4 majority) to replenish the fund proportionally by unit size; emergency uses also need approval.
Is the sinking fund interest-bearing?
Yes, it is held in a dedicated bank account by the juristic person, with annual reports provided to owners.

Why It Matters
Ignoring reserve fund allocation exposes buyers to surprise top-ups that can total tens of thousands THB, eroding investment returns in Thailand's condo market. Proper review protects long-term ownership costs and ensures building value preservation under the Condominium Act.
💡 REMAX Pro Tip
Always demand the latest juristic person financial statement and sinking fund balance before signing—aim for projects with >50 THB/sqm/unit balance to minimize future calls.
Common Misconceptions
Myth: The sinking fund is refundable when selling your unit.
Reality: Contributions stay with the building for collective use; new buyers of resale units typically don't repay it.
Myth: It's an optional developer fee negotiable at purchase.
Reality: It's legally mandated by the Condominium Act for new condos, calculated per sqm and non-negotiable.
