Buying, Renovating & Building in Portugal

Buying Property in Portugal: What to Check Before You Buy — whether land, an apartment or an entire building

— it is essential to check the property's legal and registered information.

Two key documents should be carefully reviewed: the Caderneta Predial and the Certidão Predial.

Check that:

  • Both documents have been issued within the last six months.

  • The total registered area is the same in both documents.

  • The owner's name is the same.

  • The Certidão Predial confirms whether there are any mortgages, liens or other registered charges on the property.

Before committing to a purchase, it is highly recommended to consult an architect familiar with local planning regulations and municipal procedures. An initial meeting with the relevant municipality can help identify planning constraints and avoid costly problems later.

For international buyers, local planning rules and administrative procedures may be very different from those in their home country. Professional advice before purchasing can therefore be particularly valuable.

Choosing the right architect is also important. Schedule a Zoom or in-person meeting before making a decision. A good working relationship, clear communication and mutual understanding are essential when a project may continue for several months or even years.

Before Renovating a Property in Portugal

Before starting a renovation project, several important factors should be assessed:

  • Planning and heritage restrictions — Ask your architect to check the property's planning status, location and whether the building is classified or located within a protected area. In some cases, approvals may be required from the municipality and, particularly in Lisbon, from the relevant cultural heritage authorities.

  • Building condition — Check the age and structural condition of the building with your architect. Older properties may require structural reinforcement depending on the proposed works, and an engineering assessment may be necessary.

  • Architectural drawings and budgeting — Detailed architectural drawings should be prepared before construction begins. They define areas, materials, finishes and equipment and allow for more accurate budgeting and quantities.

  • Materials and equipment — Review material and equipment options with your architect before making final decisions, taking into account design, performance, availability and budget.

Depending on the type and scope of the renovation, some works may not require a formal licensing procedure. Your architect should confirm what approvals are required before works begin.

Before Building a House in Portugal

Before starting a new-build project, it is important to assess the land, planning restrictions and construction requirements.

  • Check the land and planning restrictions — Ask your architect to assess the property's location, planning rules, building parameters and any heritage or protected-area restrictions. This will help establish what can actually be built on the site.

  • Assess the project's feasibility — Before developing the design, confirm the site's potential, including permitted building area, implantation, number of floors, access and other applicable planning requirements.

  • Develop the architectural project — Detailed architectural drawings define the design, areas, materials and finishes and provide a reliable basis for budgeting and construction.

  • Choose the contractor carefully — Check that the contractor has a valid Alvará, a registered NIF and a verifiable business address. Ask for references and examples of previous work.

  • Sign a formal contract — Before construction begins, make sure the scope of work, costs, deadlines and responsibilities are clearly defined in a written contract.

Planning & Project Licensing in Portugal

The main planning and licensing procedures in Portugal include:

  • Pedido de Informação Prévia (PIP)

  • Comunicação Prévia

  • Licenciamento

Before submitting an application, ask your architect to clarify the planning requirements with the relevant municipality. A preliminary meeting can help establish what can and cannot be done on the property and identify any specific restrictions.

Some properties have limitations relating to building area, implantation, number of floors or permitted interventions. These constraints should be understood before purchasing a property or committing to a project.

Your architect should also explain the documents, drawings, consultants, expected timeline and scope of services required for your particular application.
