Construction Quality Assurance Act

The quality assurance specialist assesses construction quality during and after construction.

• Before construction begins: the quality assurance officer verifies that the construction plan complies with technical regulations.
• During construction: the quality control inspector oversees the construction.
• After construction: if the construction complies with the regulations, the quality assurance officer will issue a certificate that you will send to the municipality. 

The Wkb will apply to new construction and renovation projects in consequence class 1 starting January 1, 2024. The consequence class indicates the level of risk associated with a structure. Consequence class 1 includes low-risk structures, such as single-family homes and simple commercial buildings. This also includes houseboats, vacation homes, and industrial buildings with a maximum of two stories. There are also exceptions, including historic buildings.

If you are planning to build or renovate, starting January 1, 2024, you can check the Omgevingsloket website ( ) to see which regulations apply and whether you need permits. You must also notify the municipality that you are starting construction. When doing so, you must also indicate who your quality assurance provider is. There is a website where you can find a quality assurance provider: .

The cost of hiring a quality assurance specialist varies depending on the structure. The actual costs will have to be determined based on practical experience.

Step 1: Hire a quality assurance specialist

You are responsible for hiring a quality assurance provider. You can find a list of quality assurance providers on the website of the Construction Quality Assurance Accreditation Organization (TOEK) at .

Step 2: Submit a building notification

You may not begin construction until you have submitted a complete notification. At least 4 weeks before construction begins, you must submit the construction notification via the Omgevingsloket:

• Go to "Requests."
• Under “Work,” select “Construction activity.”
• Select “Construction Activity (Technical) Report.”

Here, you should also indicate who your quality assurance representative is. Please provide all other requested information as well. If any information is missing, you must submit a new notification. You may begin construction four weeks after submitting the notification.

Step 3: Start construction

Two days before construction begins, you must submit this information via the Omgevingsloket at . This is known as the duty to provide information.

Step 4: Review by a quality assurance specialist

The quality assurance inspector checks before and during construction to ensure that building codes are being followed. You will receive a certificate from the quality assurance inspector if the structure complies with building codes.
Please note: The municipality can also verify compliance with building codes. It can also take enforcement action if compliance is not met. The quality assurance inspector cannot do this.

Step 5: Notify us when construction is complete

One day after construction has stopped, you must report this via the Omgevingsloket at . This is mandatory.

Step 6: Submit a completion report

You may not use the structure until you have submitted a complete notification of completion. You must do this at least 2 weeks before you intend to start using the structure. This is done through the Environmental Permit Desk. You will need the quality assurance statement (step 4) for this.

The municipality will let you know whether your completion notice has been accepted or rejected.
