Renovating in Spain: how to check which permits and approvals you need
Find the right municipal procedure for your renovation in Spain. Prepare the work description, check building approvals and confirm when work can start.
The kitchen fitter has offered a start date, but you have not checked the paperwork. You may be replacing cabinets, moving the sink or taking down a partition; each involves a different scope of work. Calling the project a small renovation does not establish what your council requires.
In Spain, you may come across the term licencia de obra menor, or minor works licence. It is a useful starting point for an enquiry, but it is not the answer for every project. The actual work, property, location and municipal rules determine the procedure. Check them before you commit to a start date.
Describe the work precisely
A kitchen renovation could mean painting, replacing units, moving water and electrical connections or changing walls. Prepare a description of the existing room and each proposed alteration, supported by photographs and a simple plan. Identify changes to window or door openings, the façade and any shared parts of the building.
If the work may affect the structure, safety, shared building systems or a building's protected status, obtain the appropriate professional assessment. A wall's thickness, or a neighbour's previous renovation, is not enough to establish that it is non-structural. Even where the paperwork follows a simplified procedure, the work itself can still require careful technical design.
Use the procedure for the property's own municipality
Barcelona City Council offers a consulta prèvia d'obres, a preliminary enquiry that identifies the applicable procedure and required documents. Its official information lists licencia (licence), comunicado (notification), enterado (acknowledgement) and actuación de urgencia (urgent work). The enquiry helps establish which route fits the proposed work.
For a home in Cabrera de Mar, Vilafranca del Penedès or another municipality, consult that council's online portal or planning department. Barcelona's procedures, fees and processing times cannot automatically be applied elsewhere. Keep the response with the property address and the description of work submitted so that it is clear what the enquiry covered.

Ask the questions that fit each part of the project
Use these examples to prepare your enquiry. They do not establish that any category of work is exempt from permission. The final requirements depend on the property and the rules that apply to it.
| Proposed work | Questions to resolve |
|---|---|
| Painting or changing finishes | Which municipal procedure applies, and are there conditions relating to protected status or waste? |
| Altering partitions or the layout | What technical assessment and documents are needed, and which installations will be affected? |
| Replacing windows, altering the façade or fitting outdoor equipment | Does the work affect shared elements, external appearance or cultural heritage protection, and what local rules apply? |
| Placing a skip or scaffolding in the street | Is a separate procedure needed to occupy public space? |

Check the owners' association requirements separately
In a shared building, the comunidad de propietarios, or owners' association, may have a role where common parts or building rules are involved. Satisfying the municipal procedure does not automatically settle those requirements. Equally, informing the association's president does not complete the council process. Give the relevant parties the same description and establish which permissions or notices are necessary.
Agree working hours, access, protection for the lift and shared areas, and waste removal. Even a small project needs space to bring materials in and take old fittings or rubble out. Sorting out those arrangements before installation helps avoid disruption and disputes with neighbours.

Put responsibility for the paperwork in writing
The quote should state whether it includes administrative work, technical documents, fees and taxes. If it says that permits are your responsibility, ask which procedures are anticipated and what information the contractor or professional will provide. Obtain the actual applicable charges rather than adding a standard municipal percentage to every project.
Identify who submits each document, the timetable and the condition that allows work to begin. Filing an application does not necessarily authorise a start the following day. If the design changes after the enquiry, ask whether the submitted documents or approval need updating. A procedure completed for one scope does not automatically cover a different project.
Keep the original work description, official responses and allocation of responsibilities with the contract. They let you check that the work being commissioned matches the proposal considered by the council and other relevant parties.
- The address and identifying details of the property.
- The existing layout and proposed work, with plans and photographs where useful.
- The municipal response and list of required documents.
- Any checks and decisions concerning the building or its shared parts.
- Who handles each step, what it costs and when work is allowed to begin.
Confirm the start conditions before booking deliveries
Base the start date on the applicable procedure, not the shortest processing time found online. Coordinate the paperwork with lead times for materials and the availability of the people doing the work. Administrative processing and construction are separate parts of the timetable. Avoid making delivery commitments that cannot be changed before the conditions for starting are clear.
If an urgent fault is discovered, ask which procedure applies to that specific situation and keep a record of the problem and proposed response. Urgency does not determine the classification of every piece of work you might then want to add. Check any expanded scope before proceeding with it.
Common questions
Does every kitchen renovation need a minor works licence?
There is no single answer under that name. The procedure depends on the work and the property. Tell the municipality whether you plan to paint, change cabinets, move plumbing or electrical connections, or alter walls.
Can I use my neighbour's permit as a guide?
It may point you towards the right council service, but it does not establish your requirements. The work, building protection, rules or other conditions may be different.
Can the contractor start once the forms are submitted?
Only if the applicable procedure and its conditions allow it. Ask for explicit confirmation of when the work may begin; submission alone does not always provide permission to start.
Agree a start date once the requirements are clear
A precise work description, the appropriate official enquiry and written responsibilities give you a practical basis for scheduling the renovation. Check that all three refer to the same project.
When the contractor proposes a date, you can then confirm whether the documents, approvals and other start conditions are in place. That is a firmer basis for organising the work than relying on what happened in another flat.
