How much can I build in Deinze?
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. In Deinze, the general building regulation of Deinze (2022) lays down a fixed rule in art. 9.3: for residential buildings, at least 1/8 of the plot must remain green and unpaved. Exceptions are sometimes possible; the Perceelscan applies the rule to the shape of the plot.
Do I need an environmental permit in Deinze?
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 Deinze?
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.

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