Renovation permits in Lisbon: what to know

The answer depends on the building, the proposed changes and the applicable rules. Calling a quotation “refurbishment” does not determine its legal category. Start with a survey and a specific description: which walls will be removed, which services will change, which exterior features will be replaced and whether the use stays the same.

Exempt works do not require advance municipal approval through licensing or prior notification. Technical standards, planning rules, heritage protection and obligations towards others still apply. Ask your professional to record the basis for the classification, rather than relying on a verbal assurance that nothing is required.

“It is in the historic centre” is not precise enough. Check whether the building is listed, under consideration for listing, part of a listed ensemble or site, inside a protection zone or identified in the municipal heritage inventory. Being in an Urban Rehabilitation Area (ARU) is not itself heritage listing.

Until 30 September 2026, the RJUE places maintenance and alteration of listed properties, or properties being considered for listing, within the licensing exception. A protection zone has its own rules: it does not automatically make every interior repainting job subject to licensing. Municipal licensing and a heritage authority’s opinion are also separate matters.

In protection zones, exemption from a heritage opinion for certain interior works depends, among other conditions, on not affecting the subsoil or features such as tiles, decorative plaster, stonework, joinery or metalwork. Removing an ornate ceiling or old doors therefore warrants checking before demolition is priced.

For windows, photograph the exterior and record the material, colour, profiles, arrangement of opening lights and opening dimensions. The RMUEL allows certain replacements retaining the design and profile; the RJUE also provides an exemption linked to energy improvements and an identical exterior finish. Heritage exceptions still matter. Better energy performance does not give unrestricted permission to change a façade.

These are different concepts. First establish the planning procedure; then meet the requirements for carrying out the work. The route cannot be chosen simply because it looks faster.

To submit an application, open Loja Lisboa and follow Novo pedido → Urbanismo. Select the correct operation and use current templates: conditional documents depend on the circumstances. In the workflow described by the municipal manual, the application is downloaded, signed and uploaded again. Saving a draft does not complete submission; confirm completion and keep the receipt and application number. Additional documents should be associated with the relevant application.

There is no single price for “the licence”, or realistic timetable for every apartment. Separate preparing the submission, administrative processing and construction. A useful proposal explains what is included and which decisions determine the start date.

• Survey, archive consultation and assessment: the work needed to establish what can be done.
• Architecture and applicable engineering designs: request the list, responsible professional and deliverables for each.
• Municipal fees, public-space occupation and other administrative costs: identify who pays them and whether they are included.
• Construction, technical supervision, testing, certification and waste: compare quotations using the same scope.
• Identified uncertainties: provide a contingency and approval process for discoveries such as concealed services or decayed timber.

Statutory decision periods are not the same as the time from a first visit to starting construction. Requests for documents, external consultations, design changes and earlier irregularities can affect the process. Ask for a programme with verifiable milestones: survey complete, design agreed, complete submission, commencement conditions met and final handover. An owner should not interpret council silence as permission to start without a review of the application.

This guide was reviewed on 20 September 2026. The RJUE amendments introduced by DL 108/2026 generally take effect on 1 October, following postponement by DL 155-B/2026. Publication of a rule, or its appearance in a consolidated text, does not mean it already applies to your application.

• Structure: interior alterations qualifying for the new structural exemption require a structural design and responsibility statement, plus seismic strengthening design where required, to be deposited with the commencement information.
• Commencement: the new wording exempts exclusively interior maintenance from the commencement information requirement. “Maintenance” does not mean any interior refurbishment or demolition.
• Heritage: a specific exemption is introduced for maintenance of listed properties or those being considered for listing, subject to a favourable opinion from the competent authority submitted with the commencement information. This is not a general exemption for all alterations.
• Use and forms: use procedures are amended, and Portaria 320/2026/1 replaces earlier forms and submission requirements from the applicable date.

Applications already submitted also need review: the transitional provisions cover, among other cases, those still at initial admissibility review. Before filing, amending or starting works from October onwards, confirm the statutory version, transitional provisions and current CML forms with your professional. The submission date alone does not resolve every case.
