Urban-planning regularisation in Liège
Does your property not fully match the plans or the permits on file? Urbexa reviews the planning situation of the building and supports you through the steps a regularisation may require.
Situations
When might a regularisation be needed?
Before a sale, a purchase or a new project, it helps to separate the existing situation from the authorised planning situation. The gaps can concern the points below.
Extension
Added volume — sometimes decades old — with no permit to be found.
Annex
An outbuilding or secondary volume whose status is unclear.
Façade changes
Openings, materials or volumes that differ from the known plans.
Conversion
An internal reorganisation that changes how the building works, sometimes its structure.
Attic fit-out
Space made habitable without the available documents recording it.
Change of use
A shop, office or workshop used as housing, or the reverse.
Extra dwellings
More units than the authorised situation recognises.
Splitting a house
A single-family house laid out as several flats.
A physical alteration does not, on its own, mean that it matches the authorised planning situation. It has to be compared with the documents available.
Diagnostic
How to check the planning situation of a property in Liège
The existing situation is the building as you walk through it. The authorised situation is what the permits and plans recognise. Urbexa separates them in this order:
01
Collect the documents on hand
Deeds, plans, permits, photos, cadastral extracts: the documents already to hand.
02
Understand the history of the property
Who changed what, and when, where the papers make that traceable.
03
Compare authorised and existing situations
Set what is recognised against what is built or used today.
04
Name the gaps
Volume, façade, use or number of dwellings: naming what differs.
05
See what needs a closer look
Some gaps can be documented. Others shape the rest of the analysis.
06
Consider the next steps
Further analysis, preparation of a permit, or another step suited to what the comparison shows.
This reading is what a planning diagnosis covers. It identifies the gaps and the procedures that can be considered.
Local context
Regularisation and building subdivision in Liège
The City of Liège publishes specific guidance on dividing buildings. It covers, among other things, housing quality, habitability, the floor area of the building, parking, and how additional dwellings are organised.
A single-family house may have been converted into several dwellings without that layout matching the authorised situation. What you can see describes the existing situation. The recognised number of dwellings depends on the permits.
Conversely, a subdivision that is still only proposed has to be studied before works start: layout, number of dwellings, access, outdoor space, habitability, parking and the rules that apply. Our work on building subdivision starts from that reading.
The detail of the City's published guidance, including what it says about floor area, is set out in our article on dividing a house in Liège.
Need the situation reviewed?
Describe the property, the documents you have and what you have in mind. Urbexa will tell you whether a planning diagnostic is the right step.
Buying and selling
Buying or selling a building in Liège
A rental building can contain several dwellings. Before a purchase or a sale, it is worth checking whether that number matches the authorised planning situation.
Older works or a change in how the property is used can create a gap with the documents on file. A diagnostic before purchase helps assess the project before larger budgets are committed.
An uncertain planning situation can also come up during a sale. A prior review gives a clearer picture of the property and of any procedures that may be needed.
Method
How a regularisation proceeds with Urbexa
When a regularisation is being considered, Urbexa works in the following order.
01
Planning diagnostic
A first reading of the property, the documents on hand, and what the owner or investor actually wants to do.
02
Review of documents and permits
Finding the plans, permits and deeds that show what was authorised.
03
Identifying the gaps
Marking the differences between the existing situation and the authorised one.
04
Studying the options
Considering which procedures can be envisaged for the property and the project.
05
Preparing the file
When a procedure is worth pursuing, assembling the documents — with or without an architect, depending on the project.
06
Filing and follow-up
Submitting the file and handling exchanges with the administration.
Depending on the file, Urbexa can then support the preparation and follow-up of a planning permit, with an architect or through a procedure without one.
Area
Urbexa works in Liège and the surrounding area
Urbexa works in Liège and in neighbouring municipalities, on a diagnostic, a regularisation or a subdivision.
The guidance mentioned here is published by the City of Liège. It does not automatically apply in other municipalities.

Questions
Common questions
Age alone does not decide the planning status of a change. Older works can be reviewed, depending on the property, on what was done and on the rules that apply.
No. Several flats describe the existing situation. The recognised number of dwellings depends on the permits. In Liège, the City also publishes guidance on subdivision, and that guidance does not automatically apply in other municipalities.
It depends on the works and on the procedure that may apply. Some conversions need a permit with an architect. Others can follow a more limited route. Urbexa identifies that during the analysis. There is no single answer for every property in Liège.
An uncertain planning situation can complicate a transaction. A prior review gives a clearer picture of the property and of any procedures that may be needed.
Because the number of dwellings you can see, an extension, or an old conversion does not tell you what is authorised. A diagnostic before a larger financial commitment helps separate apparent potential from the recognised situation.
Planning rules and practice can change, and they depend on the property and the project. An individual review remains necessary.
