The first occupancy license (LPO) is one of the most important procedures in the process of buying, selling, or legalizing a home in Spain. It acts as an official certificate confirming that a property complies with urban planning, safety, health, and accessibility regulations required for habitation.
Although many people are unaware of its importance, not having this license can lead to serious legal and financial problems. In this article, we explain what a first occupancy license is, why it is so important, how to obtain it depending on the type of property, and the risks of not having one.
In addition, we will address the required documentation, the steps to apply, the associated costs, and the key differences between the certificate of occupancy and the first occupancy license—another essential document in the real estate sector.

The first occupancy license is an administrative document issued by the corresponding city council certifying that a home or building complies with urban planning, safety, health, and accessibility regulations established by law.
This procedure is mandatory to legalize a property and allows it to be used as a residence, as well as to sign sale or rental contractsand connect basic utilities such as water, electricity, and gas.
The first occupancy license is not merely a bureaucratic formality, but an essential requirement to ensure a property’s legal and safe use. Its importance lies in several key aspects, such as confirming the home is legally habitable. Without an LPO, a property is not officially recognized as suitable for habitation, which may lead to legal issues with municipal authorities. In many cases, local councils will not authorize the connection of basic utilities (electricity, water, and gas) without this document.
It is also required for registration and sale, as most notaries request the first occupancy license to formalize the transaction. If it is missing, the buyer may face difficulties registering the property in their name.
This license is mandatory for renting, and a rental contract may be declared null and void if the property does not have an LPO. Some autonomous communities may even impose fines on owners who rent without this document.
In addition, it facilitates banking and mortgage procedures, as banks often require the LPO to grant financing, since it confirms the property complies with legal requirements. Without it, the property valuation may be lower, affecting the loan amount, and it may lead to sanctions or future issues. In extreme cases, the city council could order eviction if the property does not comply with regulations.
Not all properties follow the same process to obtain the LPO. Below, we outline the most common scenarios and how the license is obtained in each case.
In this case, the developer or builder is responsible for completing the process once the construction work has been finished.
The final building certificate (a declaration that construction complies with the approved project) is submitted, and a municipal inspection is carried out to verify compliance with regulations. If everything is in order, the license is issued.
For this type of property, it is necessary if the home has undergone structural changes, such as alterations in layout, extensions, or changes of use. In such cases, additional documentation is required, including the technical project for the alterations, the building permit (if applicable), and the certificate of completion of works.
If the property already had an LPO, renewal is usually not required. However, some municipalities require an update when selling or renting, or if there have been undeclared modifications, in which case regularization may be necessary.
Requirements vary depending on the municipality, but generally the documentation includes a signed application form provided by the city council, the technical project endorsed by an architect, the final construction certificate confirming that the building matches the approved plans, and the building permit, if there was construction or renovation work.
Additional certificates may be required, such as the energy performance certificate (mandatory for sale or rental), the electrical and gas installation certificates (required by some local councils), and an accessibility report in certain autonomous communities with specific regulations.
Municipal fees depend on the property’s cadastral value and the local council, but they typically range between €300 and €3,000.

It must be requested from the Urban Planning Department of the local council where the property is located. Some municipalities allow the procedure to be carried out online, while others require in-person submission.
The necessary documentation must be compiled, including the technical project and certificates. The application is then submitted to the city council (either physically or electronically), municipal fees are paid, and the technical inspection is awaited (in some cases, a municipal technician visits the property). A decision must then be issued. If the outcome is favorable, the license is granted; if there are observations, they must be corrected before approval.
The usual timeframe is between 1 and 3 months, although in large cities it may take longer. Factors that influence the timeline include the municipality’s workload, documentation errors, and whether an on-site inspection is required.
The cost depends on the property’s cadastral value and the municipality, but it typically ranges from €300 to €1,500 for single-family homes and from €1,000 to €3,000 for multi-unit buildings.
Not having a first occupancy license can lead to serious legal and financial consequences, including administrative fines. In some cases, local councils may impose penalties for occupying a property without an LPO or even order eviction until the situation is regularized. It may also create difficulties in sales and rentals, as notaries and registrars can refuse registration, and contracts could be declared void. In addition, utility companies may refuse to connect essential services such as water, electricity, and gas without an LPO.
There may also be obstacles to obtaining mortgages and completing sales, as banks may refuse financing if the property is not legalized, and buyers often demand price reductions if the license is missing.
Some long-term repercussions include a loss of market value for properties without an LPO and, in a future sale, the possibility that the new owner could sue the seller for concealing this defect.
It depends on the autonomous community, but in general it has been mandatory since the 2008 Land Law.
You can verify this by checking with the town hall or requesting a simple note (nota simple) from the Land Registry.
It depends on the notary, but many require it to avoid legal issues.
