How to Avoid Buying Illegal Property in Madeira

A property can look entirely ordinary and still be illegal. It can have walls, a roof, electricity, and a family living in it, and none of that confirms it was lawfully built or can be lawfully sold. In Madeira, where much of the building stock is old and a good deal of it was extended over decades, this is more common than buyers expect. The forms it takes are worth understanding separately, because they are not the same problem.

Built without a licence

The clearest case. A structure raised without the municipal licence (licença de construção) that authorises it. The building may be sound and long-standing, but legally it does not exist as it should, and that gap follows the property to every future owner.

Resolution sometimes exists through a regularisation process, and sometimes it does not. Which applies depends on the specifics, and that determination is a matter for qualified counsel, not for assumption.

Extended beyond the approved footprint

More subtle, and more frequent. The original building was licensed, but a later extension, an additional floor, an enclosed terrace, a converted outbuilding, was not. The property is partly lawful and partly not, and the unlawful part is often the part the buyer most values.

This is why the licensed plans must be compared against what physically stands on the site. A discrepancy between the two is a finding, not a detail.

Located in a protected zone

A property can be fully built and still constrained by where it sits. Madeira's Plano Diretor Municipal and national designations such as RAN (agricultural reserve) and REN (ecological reserve) restrict what may be built, extended, or changed. Land that appears developable may be nothing of the sort.

Verification here is specific: it requires checking the relevant municipality's own plan for the exact plot, because designations vary council by council and parcel by parcel. This is the single check most often skipped before a promissory contract, and the most expensive to skip.

Connected to utilities informally

Water and electricity reach some rural properties through arrangements that were never formalised: a shared spring, a connection across a neighbour's land, a supply that predates current regulation. The property functions day to day, but the connection has no legal basis and no guarantee of continuity.

These situations are resolvable more often than the others, but they should be known and priced before purchase, not discovered after.

Carrying an enforcement order

The most serious. Where the municipality has already identified an illegality and issued an order, to halt work, to demolish, or to restore, that obligation attaches to the property and transfers with it. A buyer can inherit a live legal proceeding along with the keys.

Due diligence is not optional

Each of these is found the same way: by examining the title, the licensed plans, the planning designations, and the municipal record before any commitment is made. The work is the same whether the property is listed publicly or sourced off-market; if anything it matters more off-market, where there is no agent's file to start from.

We do not advise on how to resolve an illegality. Where one is found, that is a matter for a qualified Portuguese lawyer, and the answer is sometimes that it cannot be resolved at all. The fuller process is set out in our guide to buying property in Madeira safely. The takeaway is simple. Due diligence is the difference between a clean acquisition and a long legal problem, and it is cheapest before you sign.

This article is general information, not legal advice. Planning rules differ by municipality and verification requires checking the specific Plano Diretor Municipal for the relevant council. Engage qualified Portuguese counsel before relying on any point made here.
