How much can I build in Hasselt?

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 Hasselt, the Hasselt housing quality regulation (2024) lays down a fixed rule in art. 4.3: on a plot larger than 650 m², at least 30% must remain planted and unpaved. Exceptions are sometimes possible; the Perceelscan applies the rule to the shape of the plot.

Do I need an environmental permit in Hasselt?

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 Hasselt?

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 Hasselt?

In Hasselt, the regulations ‘Woonkwaliteit (herziening)’ (only in the former municipality of Hasselt) and ‘Behoud Gezinswoningen’ (only in the former municipality of Hasselt) apply to this. For each address, the Perceelscan tells you which regulations apply to the plot. 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 Hasselt?

In Hasselt, the regulation ‘Mobiliteit’ (only in the former municipality of Hasselt) determines 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 Hasselt?

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.

Does Hasselt impose planning obligations?

Hasselt addresses this in the regulation ‘Regeling van de bijdrage in de kosten voor buitengewone infrastructuurwerken ter inrichting van het openbaar domein’ (only in the former municipality of Hasselt). 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.

In the register of plans and regulations (DSI) of the Departement Omgeving, with 62 plans for Hasselt (RUPs, BPAs and others).
