How to obtain building plan approval for interior works in Singapore

Generally, minor interior works like painting or replacing flooring dont require approval. However, works that affect structural elements, fire safety systems, or involve plumbing/sanitary works usually do. Always check with BCA or a qualified professional.

Works involving structural changes (e.g., demolishing walls), altering fire safety systems (e.g., sprinkler relocation), or changes to sanitary plumbing typically require building plan approval.

Building plans are typically submitted to the Building and Construction Authority (BCA) through CORENET e-Submission System by a Qualified Person (QP).

A QP is a registered architect or professional engineer. You need a QP to prepare and submit building plans to BCA, as they are responsible for ensuring the plans comply with regulations.

The processing time varies depending on the complexity of the project and the completeness of the submission. It can range from a few weeks to several months.

Required documents typically include architectural plans, structural plans (if applicable), fire safety plans (if applicable), calculations, and supporting documents demonstrating compliance with regulations.

Carrying out unauthorized works can result in fines, stop-work orders, and even legal action. You may also be required to reinstate the premises to its original condition.
