They talked about our services:

What is your situation?

You are selling a property that violates zoning regulations

Are you looking to sell your property, but your notary or real estate agent has turned into a doomsayer? Will zoning violations directly affect your selling price—or even make the sale difficult?

You have received a notice from the municipality

Have you received a traffic citation from your municipality—following an officer’s observation or a complaint—and are you feeling anxious?

You are passing on your estate

Do you want to pass on your estate without leaving any skeletons in the closet?

You're buying a property and want to verify that it complies with regulations

Are you looking to buy a property while making sure that (the wallpaper is to your liking) your future purchase complies with zoning regulations?

You subdivide a building to increase its value

Want to divide up a building to increase its resale value (and pay for ski vacations)?

Our team of specialists at Ubex (architects, surveyors, lawyers, urban planners, acousticians, engineers, hydrologists, etc.) will work with you to find the best solution for resolving planning violations and irregularities related to your real estate properties in Brussels, Wallonia, and Flanders.

UBEX, the only consulting firm in Belgium that specializes exclusively in urban planning regularization.

(And that's why we do it well.)

Our commitments

Adding value to your property

A property in breach of town-planning regulations is a property that will not sell, or will sell poorly. A single-family home with an undeclared annex can easily be undervalued by 20-30% or more, depending on market conditions. And potential buyers are very reluctant to buy a non-compliant property. Who wouldn't be?

Ubex not only saves you money on resale, but also allows you to increase the value of the improvements and embellishments you've made. A single-family home with a tidy annex increases its surface area, and therefore its price. CQFD.

Another way to increase your capital gain is to legally divide your property and resell it in lots. And guess what? Ubex can also help you with the feasibility of this type of project.

The certainty of a solution

A planning violation is not a problem. Just an equation to be solved. And that's exactly what we do.

We keep a close watch on regulatory developments in the sector: our experts are constantly monitoring legislative changes.

In fact, Ubex provides them with a genuine training program to enable them to build up their skills over the years, and give their customers the best possible advice. (Which is probably why some local authorities are trying to poach our staff).

Serenity

Receiving an official letter from the planning authorities giving you just 3 months to get your house in order (either by regularizing or demolishing) is stressful. We know how stressful it can be.

But there is often a third way. That's why we're here to help you talk to your local authority to find the right solution and make your demands understandable, even if you're not a specialist in planning law.

Even for a "simple" regularization file, several experts are needed: a surveyor, a PEB manager, an architect, a lawyer... With Ubex, you have just one contact: your project manager coordinates all these specialists.

S. Durieu

Kim regularized our application for a permit to paint the exterior doors of our church. She guided us diligently and professionally through the entire process. Every step of the way, we appreciated the quality of her guidance and the clarity of the instructions she always gave us, with optimism and confidence in the success of the work. Without ever reproaching us for our delays or slowness in responding to her, Kim was always very patient and courteous. So it was without a hitch or a hiccup that our infraction was regularized thanks to Kim. We'd like to thank her for all this

Sincerely,

Paul-Marie Honhon, president of the Etablissement Fabrique d'église Ste Agathe in Berchem-Ste-Agathe.

Frequently asked questions

How long does it take to regularize a property?

The deadline may vary depending on the complexity of your situation. Generally speaking, we can submit your file to the Namur municipality within 2 months of the start of our collaboration.

What are the costs of urban planning regularization?

Every situation is unique. Our fees are based on the time spent, which ensures fair and transparent billing. In 2024, our fees ranged from €591 to €8,082 (excluding VAT), and half of our cases remained under €4,858 (excluding VAT). In addition, there are filing fees charged by your municipality and, depending on the case, a site survey or an energy performance assessment (PEB). A detailed breakdown of each item can be found in our guide on the cost of urban planning regularization. The initial consultation is free and non-binding. Opening the case costs €350 (excluding VAT); you will then receive a detailed estimate, which is updated throughout the project. Our added value compared to a traditional architecture firm: we handle only this type of case.

Can I regularize my property myself if I'm in breach of planning regulations?

Although technically possible, the complexity of Belgium's town-planning regulations makes the process difficult for non-professionals. Putting together the application file can be laborious, and the list of documents to be supplied lengthy. For the application to be declared compliant by the town planning department, it must include a complete file of plans and other architectural documents, as well as an administrative section. When you call on Ubex , you can be sure of a stress-free and efficient regularization of your project.

What is urban planning regularization?

A regularization permit is the administrative process used to regularize the administrative status of a property that does not comply with local zoning regulations and/or those of the CoDT (Code of Territorial Development applicable in Wallonia, which defines the rules for proper territorial planning). This procedure generally concerns the “unauthorized” construction of additions or modifications made to a property without a permit. The authorities may then impose fines or require the property to be restored to its original condition.

What are the most common offences requiring a licence application?

Undeclared extensions, the division of a property into several dwellings/kots, changes of use following the conversion of a property or the construction of a carport over 40m2 are the most frequent requests for regularization that our architects deal with.
