A planning regularisation brings a property into compliance when the existing situation does not match issued authorisations. It can cover annexes, transformations, subdivision, façade changes, loft conversions or outdoor works. Urbexa structures these procedures clearly.

Contact us

Comparing the existing state with available authorisations reveals gaps. An extension, interior change or change of use may require regularisation. Urbexa analyses this with the municipal planning service.

Contact us

It depends on the project. Major structural works usually require an architect. In other cases, an Annex 6 procedure without an architect may apply. Urbexa determines the correct path.

Contact us

Some procedures can be filed without an architect for existing situations or limited interventions. A structured file remains essential. Urbexa prepares the dossier for coherence and admissibility.

Contact us

Timelines vary by file, complexity and municipality. After filing, the municipality has 30 days to confirm completeness. Planning services then have 30, 75 or 115 calendar days to decide. Additional requests can extend timelines.

Contact us

Incomplete files trigger requests for additional information that pause the process. Urbexa prepares rigorous dossiers to avoid this back-and-forth.

Contact us

Refusal can stem from site-specific constraints. Urbexa helps define next steps: adapt the project, refile, or pursue an adapted regularisation. Specialist counsel can be involved if needed.

Contact us

Yes. Urbexa manages administrative follow-up and exchanges with competent services, including responses to additional requests — one dedicated contact for you.

Selling a property with planning irregularities is increasingly difficult. Buyers and notaries pay close attention. Early regularisation secures the transaction. Urbexa supports this before sale.

A rental permit is mandatory for small dwellings (habitable rooms under 28 m²). It certifies safety, salubrity and habitability standards. Urbexa helps owners obtain it and bring properties into compliance.

Contact us

Yes, every 5 years. Urbexa helps owners track these deadlines.

Contact us

Visit report and compliance certificate by an approved inspector; gas and electricity certificates (< 5 years); heating inspection proof; energy certificate (< 10 years); rental declaration. The dwelling must also meet planning and fire rules.

Subdivision is tightly regulated and depends on configuration, location and municipal rules. Urbexa assesses feasibility — from yield analysis to permit filing.

Contact us

Yes. Unauthorised subdivisions require regularisation. Adaptations may be needed. Urbexa structures a solution to maximise the application's security.

From 2028, energy-performance requirements apply in the years following acquisition and may imply upgrade works. Urbexa helps analyse and secure the project.
