Condo ownership

Sinking fund versus common-area fee in Thailand.

One supports recurring shared operations; the other reserves money for larger future building work.

Answer first

A common-area fee is generally the recurring contribution used for shared operations such as staff, cleaning, security, utilities, maintenance and management. A sinking fund is generally a reserve for substantial future repairs, replacements or capital work. Thailand does not impose one universal amount for every condominium; the exact obligations come from the Condominium Act, registered regulations, ownership ratio, budgets and valid co-owner resolutions.

Comparison

Different purposes, different questions.

Common-area fee

Recurring operating money for shared property and services. Review the current rate, billing cycle, annual budget, arrears and recent increases.

Sinking fund

Reserve funding for major future work. Review the balance, collection history, authorized uses, planned projects and whether additional contributions are expected.

Buyer due diligence

Documents to request.

  • Registered condominium regulations and juristic-person rules.
  • Current common-expense rate and unit calculation basis.
  • Latest annual budget and available financial statements.
  • Sinking-fund balance or disclosure and major-work plan.
  • Recent co-owner meeting minutes and approved assessments.
  • Outstanding unit debt and debt-free certificate requirements.
No invented benchmark

Judge the building from its own records.

A low recurring fee is not automatically good value, and a large reserve is not automatically sufficient. Building age, systems, facilities, deferred maintenance, insurance, staffing and planned work all affect funding needs. Compare the actual budget and reserve position with the building's obligations rather than relying on a generic market number.

Review the building finances before buying.

Ask for the actual fee schedule, reserve position, meeting minutes and planned major works for the exact condominium.

FAQ

Condominium fee questions.

Are a sinking fund and common-area fee the same charge?

No. A common-area fee generally supports recurring condominium operations and shared services. A sinking fund is a reserve intended for larger future repair, replacement or capital work, subject to the condominium's registered rules and resolutions.

Is there one national fee amount for every condominium?

No. The amount and collection method depend on the condominium's registered regulations, unit ownership ratio, juristic-person budget and valid co-owner resolutions. Review the documents for the exact building.

Can additional assessments be charged?

A condominium may require additional funding when validly authorized under the Condominium Act, registered regulations and co-owner resolutions. Buyers should review recent meeting minutes and outstanding obligations.

Who owes unpaid common expenses after a sale?

Outstanding common expenses can affect transfer documentation and the condominium juristic person's debt-free certification. The sale contract should allocate responsibility, but the transfer file must satisfy the applicable legal and juristic-person requirements.

What should a buyer request before transfer?

Request the registered condominium regulations, current fee schedule, sinking-fund records or disclosure, recent budgets, audited accounts where available, meeting minutes, planned major works and the debt-free certificate process.
