What to consider when renovating a house in Portugal

There are a few things to think about before renovating your Portuguese home. Let’s take a look at everything you need to know!

Is it a protected or listed building?

Portugal has many beautiful, historic countryside properties that offer a slow and mindful way of life. However, those buildings with particular historical or cultural significance often come with additional planning restrictions.

You’ll need to create a renovation plan that takes these restrictions into consideration. You may also need to seek special permission if your building is on protected land, such as a historic site or national park.

Consult experts from local heritage and environmental organizations for support, as they can help you get the necessary permits for your plans.¹

How does Portuguese planning permission work?

Planning permission rules and regulations differ by municipality, so you’ll need to check with your local authorities for what you can and can’t do to your property.

You’ll likely need planning permission to renovate the structure of your home, both internally and externally. This includes submitting plans to your local authorities for approval.

You’ll also need to register your completed work using a final habitation licence, known as a licença de utilização. This certifies that your property is fully compliant with local regulations.¹

How do property evaluations in Portugal work?

A property evaluation can help you check for any problems with your house – and you can avoid costly mistakes further down the line.

You can use the Royal Institution of Chartered Surveyors (RICS) in Portugal to find an experienced surveyor for your home inspection.⁵

You may also need a property survey if you want to get a mortgage in Portugal. This will ensure everything is up to code.

Do you have a renovation schedule in place?

Before starting your renovations, you’ll need to create a renovation schedule for your property. This will help you come up with a suitable timeline for your home improvements.

Your plan will include key tasks like getting materials, hiring a contractor, working with laborers, and completing each of your changes.

Do you hire contractors for home renovations in Portugal?

In most cases, you shouldn’t complete renovations yourself. It’s always best to work with an experienced contractor who can organize your project and provide you with expert support.

A contractor is an essential part of any renovation project. Your contractor will oversee the full construction process, including hiring laborers and sourcing the right materials.

Look out for contractors who are certified by the Instituto da Construção e do Imobiliário (InCI) in Portugal.¹

Do you have the right insurance?

Your contractor will need to take out insurance to cover non-contractual liability arising from construction activity. Their insurance will also need to cover labor accidents, automobile liability, and equipment.⁶

Speak to a Portuguese lawyer for more information about your contractor’s insurance obligations. You should only work with licensed contractors who have the appropriate insurance for your property work.

Do you have a contingency plan in place?

A contingency plan ensures you have enough money to complete your renovation project. Put aside funds to cover any unforeseen costs.

You may want to build an extra 25% to 30% into your renovation budget if you’re renovating an old or historic building.⁴ This can help you handle any problems that come up once you’ve started your work.

What do you do if something goes wrong?

If you encounter an issue during your Portuguese home renovation, speak to a lawyer as soon as possible. You may need support dealing with planning permission, for example, or incomplete renovations.

Are there fees and tax considerations for renovating a house in Portugal?

There are some additional costs to consider when renovating a house in Portugal. You’ll need to think about contractor fees and local taxes for your property project.

Permit and licensing fees in Portugal can range from 500 EUR to 3000 EUR, but this price may exceed 5000 EUR for historic or protected buildings. Contractors typically charge 20% to 40% overhead.⁴

You’ll also need to consider property taxes in Portugal. All buyers must pay property transfer tax, known as Imposto Municipal sobre as Transmissões Onerosas de Imóveis (IMT). Your tax rate will depend on property use, type, and location.⁷

You may be exempt from IMT and other property taxes if you meet certain renovation criteria. For example, if you purchase a property for rehabilitation with the intention of living there permanently.³

How long does it take to renovate a house in Portugal?

The amount of time it takes to renovate a house in Portugal will depend on the scale of your renovations. Fitting a new bathroom is likely to take longer than a paint job, for example.

Your renovations could take anywhere from a few months to up to 3 years. This includes time to get the right permits, hire a contractor, and complete construction.⁸


Portugal is an attractive location for foreigners to purchase property. You can renovate your Portuguese home to earn rental income or create a beautiful vacation spot for you and your family.

However, it’s important to be prepared. You’ll need to get the appropriate planning permission for your renovations – and you’ll need to work with experienced professionals to complete your project on time.
