Do I need an environmental permit in Boom?

For most works, yes: building, renovating, demolishing and splitting a dwelling generally require an environmental permit (omgevingsvergunning, formerly called the building permit or planning permit), which you apply for through the Omgevingsloket portal. Some minor works are exempt or only require a notification: vlaanderen.be sets out the rules. For each address, the Perceelscan also shows the existing permits.

Can I demolish and rebuild in Boom?

Demolition usually requires an environmental permit. What you may build afterwards is determined by the plan and the regulations that apply to the plot; heritage status, a plan in preparation or an expropriation can stand in the way. The Perceelscan sets it all out for each address.
