Procedures to legalize a home with Reformia
The price of the AFO, for the legalization of a property, is around 5,000 € on average. You need to take into account that the project alone can cost between 1,500 € and 3,000 €, to which you must add other procedures necessary for legalization: payment of taxes and fees, first occupancy license, deeds and registration.
1. Contact an architect or architecture firmTo start the legalization procedures for a home, you must begin by contacting an architect or firm, as it is necessary to have a technical report prepared by this professional. To do this, the architect must conduct an in-depth review of the property and analyze that all its characteristics comply with what is established by the Technical Building Code and the urban planning regulations of the corresponding Autonomous Community.
The first step to legalize a house is to contact an architect, whose technical report is mandatory. This professional will conduct a detailed inspection of the property to verify compliance with the Building Technical Code. The cost of the legalization project is around 2,200 €, making it essential to choose an architect experienced in this type of procedure.
2. Documentation necessary for legalizationThe architect in charge of making the legalization report or project must contact the municipality's architect, who will inform them of the specific documentation required and the applications that must be submitted.
The architect must coordinate with the municipal technical staff to determine the specific documentation required for your autonomous community. This step is crucial to avoid delays and ensure all necessary information is gathered before drafting the project. Documentation requirements vary by location, so there is no fixed additional cost at this stage.
3. Preparation of the legalization projectWith all the information in hand, the architect will be able to draft a comprehensive technical report that must consist of a summary, plans and graphic documentation, applicable technical regulations, measurements, annexes and, in some cases, a certificate of completion of work is also required. The project must include all information about the home and the land on which it is built, showing the height of the building, the distance to the property lines, the percentage of occupation, the measurements of usable area and total area, etc.
With all information gathered, the architect prepares a comprehensive technical report including plans, descriptive memoirs, and required certificates. This project details characteristics such as building height, land occupancy, and useful areas. The cost of this preparation is around 2,200 €, serving as the foundation document for requesting the license.
The price of the AFO, for the legalization of a property, is around 5,000 € on average.

4. Request legalization licenseOnce this technical report is complete, you can request the legalization license. This procedure is carried out in the urban planning department of the corresponding municipality. Once the documents are submitted, you must wait for the competent body to resolve the case and give approval, if applicable.
Once the technical report is complete, the application is submitted to the municipal urban planning department. This procedure has a cost in fees of approximately 1,500 € which varies by municipality. Resolution time can range from several months, so it is advisable to contact the town hall to learn about expected timeframes.
What can change your final price
Even similar projects can end with different budgets. These are the factors that most often push costs up or down.
Property size and complexity
Larger homes or those with irregular construction require more detailed and expensive technical projects. A 100 m² apartment will have a very different price than a 300 m² single-family home.
Status of existing documentation
If the house lacks documentation entirely or has only old plans, topographic surveys and archival work will be necessary, which significantly increases the cost of the process. Having partial documentation reduces expenses.
Renovations or extensions carried out without permits
Unauthorized constructions require additional structural analysis and possible regulatory adaptations, which increases project costs and administrative procedures.
Autonomous community and municipality
Administrative fees and requirements vary significantly between regions and municipalities. Some areas have more complex and costly processes than others.

Although legalization of a home is always advisable, there are circumstances where it will be essential:
How to know if a home is legal?
The easiest way to check if a home is legal is through the first occupancy license. This document guarantees that the property meets all legal requirements from an urban planning perspective and meets the criteria for habitability.
- To be able to sell or rent the property, as a deed and habitability certificate are required. Without them, you will not be able to contract basic utilities.
- To apply for a mortgage.
- To obtain a habitability certificate or a building permit.
- In the case of wanting to register the property in the Property Registry, the Land Registry or a tourist rental registry.
