How much can I build in Duffel?
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 Duffel?
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 Duffel?
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 Duffel?
For Duffel, the register lists no municipal regulation on housing; the plan and the regional rules then apply. If in doubt, check with the municipality. Splitting a dwelling into several dwellings generally requires an environmental permit, even without any building works (see splitting a dwelling on vlaanderen.be).
How many parking spaces must I provide in Duffel?
In Duffel, the regulations ‘Stedenbouwkundige verordening op het aanleggen van autoparkeerplaatsen en fietsenstallingen’ and ‘Algemene bouwverordening compensatoire vergoeding voor ontbrekende parkeerplaatsen’ determine how many car and bicycle parking spaces a project must provide; this depends on the number of dwellings or the floor area.
Do I need to install a rainwater tank in Duffel?
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. Duffel has its own rules on water in the regulation ‘Algemene stedenbouwkundige verordening baangrachten’.
Does Duffel impose planning obligations?
Duffel addresses this in the regulation ‘Stedenbouwkundige verordening inzake financiële lasten bij omgevingsvergunningen’. A planning obligation is a piece of work or a contribution that the permitting authority can attach to an environmental permit, for example for a larger housing project.
