Whose responsibility it is
The owner's. Owners, usufructuaries, tenants or whoever holds the land are primarily responsible for its upkeep and cleaning, and must keep it in conditions of health and safety.
That holds even where the waste was put there by other people. An unfenced, unmaintained plot attracts dumping, and the duty to keep it clear stays with whoever holds it.
What the council can do, and does
This is the part almost nobody knows. The council is not powerless just because the land is private.
- It notifies the responsible party to carry out the outstanding work within a set deadline
- If that deadline passes, it can proceed to coercive execution: meaning the clearing becomes the council's to carry out
- The cost of that clearing falls on the responsible party, and the notification says so
- If they do not pay, a fiscal enforcement process is opened to recover it
What if nobody knows who owns it?
The most common objection, and it also has an answer. Councils have access to the property's tax records and to the identification and tax domicile of owners, as well as to the Balcão Único do Prédio.
Where the responsible party cannot be located and cannot be notified any other way, a public notice can be posted at the site and on the council website for five days. If there is no response, the council begins the clearing work.
So "nobody knows who owns it" slows the process down; it does not stop it.
How to report it effectively
- Exact location of the plot: coordinates, or street and adjoining buildings
- Photos from several angles, taken from the public road. Do not enter the plot: it is private property and entering weakens your position
- The type of waste: rubble, household waste, vehicles, accumulated green waste
- How long it has been going on and whether it is getting worse
- Concrete risks if any: pests, standing water, fire risk, children able to access it, hazardous material. This is what sets priority
What not to do
Do not organise a group to clear the plot. It is private property; entering without the owner's permission creates a problem for you, not for them.
There is also a practical reason: clearing it destroys the evidence that would have compelled someone to act, and the plot refills within months with nothing changed about who is responsible.
The effective approach is the opposite: document it well and let the council use the mechanism it already has.
Why the history matters more here than anywhere
More than in any other case, this process runs on documented evidence. The council will be notifying a private party, setting them a deadline and potentially billing them, and that requires a properly built file, not a phone complaint.
A photographed, dated record of the same plot over months, showing accumulation getting worse, is the kind of material that supports a notification. That is what keeping the report open and reopening it on CleanSpot is for, rather than starting a fresh complaint each time.

Can the council really clear private land?
Yes, by coercive execution, after notifying the responsible party who then misses the set deadline. The costs fall on that party and can be recovered through fiscal enforcement.
What if the owner lives abroad or is unknown?
The council has access to the property's tax records. Where notification is not possible, it can post a public notice at the site and on its website for five days, after which it starts the work.
Can I clear the land myself?
Not without the owner's permission. It is private property, and beyond the legal problem you would be destroying the evidence that compels the responsible party to act.
How long does it take?
It depends on the council and on how hard the owner is to identify. The process has several stages, notification, deadline, possible coercive execution, and none is immediate. Documenting well from the start is what speeds it up most.
