How much can I build in Kalmthout?
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 Kalmthout?
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 Kalmthout?
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. Kalmthout has its own rules for buildings of heritage value in the regulation ‘waardevolle gebouwen’.
Can I split a dwelling into several units in Kalmthout?
For Kalmthout, 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 Kalmthout?
For Kalmthout, the register lists no municipal regulation on parking; the plan and the regional rules then apply, and the permitting authority decides on a case-by-case basis.
Do I need to install a rainwater tank in Kalmthout?
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. Kalmthout has its own rules on rainwater in the regulation ‘de lozing van huishoudelijk afvalwater, de verplichte aansluiting op de openbare riolering en de afkoppeling van hemelwater afkomstig van particuliere woningen en gebouwen’.
Can I cut down a tree in Kalmthout?
