How much can I build in Grimbergen?
That depends on the plot: the zoning plan that applies (the regional zoning plan, a RUP or a BPA), the regulations and what is there now. The Perceelscan works it out for each address: how many m² of floor area may legally be built, and how many are already built.
Do I need an environmental permit in Grimbergen?
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 Grimbergen?
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.
Can I split a dwelling into several units in Grimbergen?
For Grimbergen, the register lists no separate regulation on housing, but the general regulation ‘Gemeentelijke stedenbouwkundige verordening’ may contain rules on it.

Splitting a dwelling into several dwellings generally requires an environmental permit, even without any building works (see splitting a dwelling on vlaanderen.be).

Do I need to install a rainwater tank in Grimbergen?
Often, yes, when you build, rebuild or extend a building or a paved surface: the regional regulation on rainwater (2023) then sets rules for collecting and reusing rainwater, letting it soak into the ground or buffering it. Which measure your project requires depends on its surface area. In the province of Flemish Brabant, the regulation ‘Provinciale verordening hemelwater’ also applies.
