A patio cover lets you enjoy your garden for longer. But before you start dreaming about lighting, sliding glass walls, or a louvered roof, there’s one more important question: Do you need a permit?
Since March 1, 2026 , the rules in Flanders have changed. That’s why we’d like to take a moment in this blog to explain what you need to keep in mind from now on.
When don't you need a permit?
For certain detached patio covers may be eligible for an exemption.
To do so, you must take the following conditions into account, among others:
- All freestanding outbuildings combined may not exceed 40 m² in total;
- The maximum height is 3.5 meters;
- In the side yard, you must leave at least 3 meters from the property line ;
- in the backyard, at least 1 meter;
- The structure must be located within 30 meters of the residence .
For example, do you already have a freestanding garden shed measuring 10 m²? If so, that area counts toward the 40 m² limit, leaving a maximum of 30 m² remaining for other freestanding outbuildings, such as your patio cover.
What if the patio cover is attached to your house?
Will your patio cover be permanently attached to your home? If so, different rules apply than for a freestanding canopy.
Before March 1, 2026, a simple notification was still sufficient for certain attached structures. That rule has been abolished. This means that you should not cannot simply be considered exempt from a permit, even if it is smaller than 40 m².
If the canopy increases the building volume of your home, you may need a environmental permit may be required. Therefore, check with your local municipality or through the Omgevingsloket in advance to find out which rules apply to your project.
Always check the rules for your lot
In addition to Flemish regulations, local regulations may also play a role, for example through a Regional Urban Plan (RUP), subdivision regulations, or heritage rules.
Therefore, before installing your patio cover, always check with your local municipality or through the Omgevingsloket to find out exactly which regulations apply to your home and property.
