Prior information request: clarify what you can build before buying

How to prepare a prior information request, distinguish informal advice from a municipal decision and assess its conditions before buying land.

A listing that promises building potential does not answer the main question: can this plot accommodate your intended project? A prior information request helps obtain a decision on a specific proposal.

Start with the question that matters

“Can I build?” is too vague. Describe the intended use, approximate footprint, floor area, number of storeys and access. A house, two accommodation units and an agricultural warehouse are different proposals. The same plot may allow one solution but not another.

Before applying, confirm the location and gather the documents in the guide to buying land in the Algarve. Do not base the assessment solely on the marker shown in the listing.

Informal advice, a formal request and construction

A discussion at the council or a look at its map helps direct your research. On its own, it does not amount to a favourable decision on your project.

A prior information request, called a pedido de informação prévia or PIP in Portugal, is a formal procedure under the Legal Framework for Urban Development and Building. Its decision can bind the competent authorities within its scope, conditions and effective period.

You should not treat every PIP as a building licence either. Its effects depend on what the application covers. Certain sufficiently detailed favourable decisions can lead to exemption from prior planning control. This requires checking the legal requirements and the obligations that still apply before construction. Ask your professional adviser to identify the procedure for your case.

Prepare the plot information and proposal

With an architect or another qualified professional, organise:

  • The plot's identity, boundaries and relationship to neighbouring properties.
  • Land registry and tax register information that allows its identity to be checked.
  • A location plan and a survey suitable for the proposal.
  • A description of the use, dimensions, footprint and access arrangements.
  • Information on water, drainage and other infrastructure.
  • Specific questions about plans, easements and restrictions.

This is a preparation checklist, not a universal list of mandatory application documents. The required information depends on the operation and scope of the request. Check the current form and applicable ordinance. If you do not yet own the land, clarify how to identify the owner and apply in your present capacity.

Apply to the competent municipality

Submit the request to the municipal council where the land is located. Check the available channel, file formats and required documents. Tavira, for example, provides forms and different annexes for different operations.

Consult the municipal fee schedule currently in force. Separate administrative fees from professional fees and any surveys or studies required. There is no single price for the whole Algarve.

Ask which statutory decision period applies and track the application. External consultations or requests for further documents can affect processing. Do not treat an estimate given at reception as a guaranteed decision date.

Read the whole decision

Imagine a favourable PIP for a house with a specified footprint, conditional on resolving access. It does not automatically confirm a larger house, a different position or the cost of providing that access.

Compare the decision with the approved plans, opinions, conditions and validity. A partial response does not resolve matters left unassessed. For territorial restrictions, also read RAN, REN and other land constraints.

Before making a commitment

Give the complete file to the professional assisting your purchase. If you negotiate a condition concerning development feasibility, specify the intended project, required documents and consequences of an unsuitable outcome in writing. Avoid vague wording such as “subject to approval”.

Checked on 17 September 2026: Decree-Law No. 155-B/2026 postponed the commencement of the changes in Decree-Law No. 108/2026 until 1 October. Confirm the statutory wording and transitional rules applicable on the date of your procedure.
