Documents needed to license building works: the instruction-elements checklist
A significant share of permitting processes do not stumble on the quality of the design — they stumble on the instruction of the application. A document is missing, a certificate of technical responsibility does not follow the legal template, a drawing does not comply with the required format, and the process is held up for weeks or rejected outright. Since 2024, the list of documents has been standardised nationwide by Portaria n.º 71-A/2024 — and the law has become far less tolerant of incomplete applications.
At CertiAmb, preparing the application file is an integral part of the architectural design and permitting support we provide: an application correctly instructed at the first attempt saves months. In this article we explain which documents the municipality requires, how the submission is phased, what preliminary screening involves and what changes on 3 August 2026 with Decreto-Lei n.º 108/2026.
The procedure determines the documents
Before the list of documents comes a prior question: which procedure applies? Under Article 4 of the RJUE (Decreto-Lei n.º 555/99, as amended), an urban operation may be subject to a licence, to prior communication, or be exempt from prior planning control. Each route has its own instruction elements — and getting the initial classification wrong compromises everything that follows. We explain the full process in our article on how construction permitting works in Portugal and cover works exempt from prior control in a dedicated piece.
There are also procedures with specific instruction requirements, such as the legalisation of existing buildings, where the usual elements are supplemented by rigorous surveys of what was actually built. Here we focus on the most common case: an application to license building works.
Portaria n.º 71-A/2024: the national list of instruction elements
Portaria n.º 71-A/2024, de 27 de fevereiro, adopted in the wake of the Simplex urban-planning reform (Decreto-Lei n.º 10/2024, de 8 de janeiro), identifies the elements that must accompany the procedures under the RJUE, repealing Portaria n.º 113/2015. In force since 4 March 2024, it is organised into three annexes:
- Annex I — the instruction elements themselves, defined according to the type and complexity of the urban operation;
- Annex II — the conditions for presenting those elements: digital formats, organisation and the rules for written and drawn documents;
- Annex III — the templates for the technicians' certificates of responsibility.
The purpose is standardisation: the list is the same across the country, putting an end to the ad hoc demands that used to vary from municipality to municipality. The law reinforces it with an important principle — the absence of an element that the administration can remedy of its own motion cannot justify an invitation to correct the application, nor its rejection.
Checklist: what accompanies an application to license building works
In practical terms, and depending on the operation, an application to license building works is instructed with, among others, the following elements:
- Legal standing and identification of the property: the land registry certificate (or the access code to the permanent certificate) and documents proving a legal right that allows the applicant to carry out the operation;
- Location: a georeferenced location plan delimiting the area covered by the operation, and a topographic survey;
- Descriptive and justificatory report: areas, proposed uses and conformity with the applicable territorial plans;
- Drawn elements of the architectural design: site plan, floor plans, elevations, sections and construction details, in the scales and formats set out in Annex II;
- Certificates of technical responsibility of the design authors and the design coordinator, following the Annex III templates, with proof of valid registration with the relevant professional association;
- Works schedule and estimate of the total cost of the works — which underpin the execution deadline and the calculation of municipal fees;
- Accessibility plan, where required;
- Fire safety: a fire safety form per type of use, for operations in the 1st risk category, or a dedicated fire safety (SCIE) design in all other cases;
- Acoustics: an acoustic design, under the RRAE regulation;
- Supporting elements: photographs of the building or site, the statistical data form and, where one exists, a favourable prior information decision still in force.
The exact list always depends on the type of works, the use and the location — one of the reasons why checking the framework should precede assembling the file.
From architecture to the engineering disciplines: the phased submission
In the licensing of building works, the process advances on two fronts. First, the architectural design: the municipal council decides on it within 30 days, and its appraisal is confined to conformity with the territorial plans, easements and public-interest restrictions, the proposed use, the urban and landscape integration and the capacity of the infrastructure (Article 20 of the RJUE).
Then come the engineering-discipline designs: they may be submitted with the initial application or within six months of notification of the approval of the architectural design, extendable once by a further three months. Failure to submit them suspends the process for up to six months, after which it lapses. Depending on the works, they include structural stability, the building water-supply and wastewater networks, rainwater drainage, gas, electricity and telecommunications, thermal performance — accompanied by the SCE energy pre-certificate (Decreto-Lei n.º 101-D/2020) —, acoustics, HVAC and fire safety.
One decisive feature of the current regime: the certificates of responsibility of the discipline designers constitute sufficient guarantee of compliance with the technical rules, excluding any prior appraisal by the municipal services. The municipality is in fact barred from appraising the engineering designs — which means the responsibility falls entirely on those who sign them. That is why the coordinated development of the engineering-discipline designs matters so much: with no public review of their content, the rigour has to come from the design team. The final decision is subject to overall deadlines — 120, 150 or 200 days, depending on the gross construction area — with tacit approval at their expiry (Article 23).
Screening and preliminary appraisal: a single opportunity to correct
Once the application is submitted, screening follows (Article 11 of the RJUE). Under the wording in force in July 2026, the mayor may issue a decision to correct the application — where the identification of the applicant, the request or the location is missing, or where a required instruction document indispensable to assessing the request is absent and cannot be supplied by the administration itself —, a preliminary rejection, where the request is manifestly contrary to the applicable legal or regulatory rules, or a decision to close the procedure, where the operation is exempt or subject to prior communication.
The critical point lies in what follows: the applicant is notified once only to correct or complete the application, within 15 days, on pain of preliminary rejection. Conversely, if within those 15 days there is neither a rejection nor an invitation to correct, the application is deemed correctly instructed — no further corrections may be requested, nor may the request be refused on the grounds of incomplete instruction. It is a double-edged rule: it gives certainty to those who submit complete files and penalises, with no second chance, those who improvise. If an application is rejected, a new one for the same purpose may reuse the previous documents that remain valid.
Electronic platforms: where the file is submitted
Urban-planning procedures are now fully dematerialised. Under Article 8-A of the RJUE, applications are submitted through an electronic platform — and the Electronic Platform for Urban Planning Procedures has been mandatory for municipalities since 5 January 2026, with no procedural steps or documents not provided for in it allowed. The written and drawn elements must comply with the formats and organisation rules of Annex II of Portaria n.º 71-A/2024, and fees are paid by self-assessment.
For the applicant, this means that formal errors — badly structured files, drawings missing required information, absent signatures — are detected immediately and can block the submission itself. The "digital" quality of the file has become as important as its technical content.
What changes on 3 August 2026: Decreto-Lei n.º 108/2026
Decreto-Lei n.º 108/2026, de 29 de maio, made the 21st amendment to the RJUE. The changes enter into force on 3 August 2026 and apply to procedures started after that date and to pending ones still at the screening stage. As regards the instruction of applications, the highlights are:
- Strictly formal screening: municipal intervention before the works becomes a mere formal check that the documents have been delivered, with no appraisal of the merits and no rejection, at that stage, on the grounds of the substantive invalidity of the request;
- Shorter correction period: where indispensable elements are missing and cannot be supplied by the administration itself, the applicant is notified to correct or complete the application within 10 days, with the screening period suspended, on pain of preliminary rejection;
- Summary application form and urban-planning title: applications will include a form summarising the essential elements of the operation, which forms part of the urban-planning title — a document whose existence will have to be mentioned in property transfer contracts;
- Stricter prior communication: submitting a prior communication without the necessary instruction elements, or without proof of payment of the fees, becomes an administrative offence;
- Intermediate deadlines with tacit approval at the end of each stage — 30 days for the appraisal of the architectural design and 20 days for the final decision on building works;
- Revision of the implementing ordinances: the decree-law provides for the revision of the RJUE ordinances — including the application templates and the instruction elements. At the time of writing, the new ordinances have not yet been published, so Portaria n.º 71-A/2024 remains fully in force.
The overall direction is clear: less administrative review of content, more responsibility on the technicians and heavier sanctions for badly instructed applications. Those who prepare the files have ever less room for error.
Incomplete applications: the mistakes that cost months
In practice, the grounds for correction requests and rejections repeat themselves:
- certificates of responsibility that do not follow the Annex III templates, or signed by technicians without valid professional registration;
- drawings outside the required scales and formats, or inconsistent with the descriptive report;
- missing operation-specific elements — the accessibility plan, the fire safety form, the acoustic design;
- discipline designs submitted without coordination with each other and with the architecture, triggering chain revisions;
- choosing the wrong procedure — applying for a licence where prior communication sufficed, or proceeding as "exempt" when the works were not.
Each request for correction uses up the single correction opportunity; each rejection means restarting the procedure. At CertiAmb, the file is assembled in an integrated way — architecture, engineering disciplines and administrative instruction prepared by the same team, with cross-checking before submission. It is this discipline that allows complete applications to be submitted at the first attempt, and prevents a good design from being held hostage to a missing document.
Frequently asked questions
Which documents are needed to apply for a building licence?
The elements in Annex I of Portaria n.º 71-A/2024: as a rule, the land registry certificate and proof of legal standing, a georeferenced location plan and topographic survey, the descriptive report, the drawn elements of the architectural design, the certificates of technical responsibility, the works schedule and cost estimate, plus operation-specific elements such as the accessibility plan, the fire safety form or the acoustic design.
Can the municipality demand documents that are not in the Portaria?
Portaria n.º 71-A/2024 standardised the elements nationwide and, with the Electronic Platform for Urban Planning Procedures, no steps or documents not provided for in it may be adopted. Nor can applicants be asked for anything the administration can supply of its own motion.
What happens if a document is missing?
The applicant is notified once only to correct or complete the application within 15 days, on pain of preliminary rejection (Article 11 of the RJUE). If there is neither an invitation nor a rejection within that period, the application is deemed correctly instructed and no further corrections may be requested.
When are the engineering-discipline designs submitted?
With the initial application or within six months of the approval of the architectural design, extendable once by three months. Their certificates of responsibility dispense with prior municipal appraisal — the responsibility rests with the technicians who sign them.
What changes under DL 108/2026?
From 3 August 2026, screening becomes a formal check on the delivery of the documents, with corrections within 10 days; the summary application form and the urban-planning title are introduced; and the implementing ordinances — including the one on instruction elements — will be revised. Until then, Portaria n.º 71-A/2024 remains in force.
Closing notes
Permitting in Portugal is moving towards a model in which the administration checks less and less and private responsibility counts for more and more. In that model, the instruction file is no longer incidental paperwork: it is the piece that decides whether the process moves forward or goes back to square one. If you are preparing a licensing application and want a complete, correctly instructed file from the first submission, talk to the CertiAmb team.
