Hearing and consent of neighbours

Construction project often require hearing the neighbours. The consent of a neighbour is needed if the construction project is located close to the border of the neighbour's plot or it affects the neighbour's property in some other way.

Many construction projects involve hearing the neighbours. In a hearing, the neighbour is presented with the project's plans and possible deviations and their justifications. The neighbour signs the form and confirms that they have been heard concerning the matter. In the hearing, the neighbour can present justified opinions of the project.

The city can take care of hearing the neighbour. On Lupapiste, select the section "Kunta kuulee kaikki naapurit" ("The municipality hears all the neighbours") of the building permit application if you want the city to take care of the hearing. The service is subject to a charge.

In an one-family house project, the city takes care of the hearing of the neighbours. The service is free of charge.

The hearing and the consent of the neighbour are two different things. If the project requires the consent of a neighbour, the builder must obtain the consent.

A construction project requires the consent of a neighbour if the building or structure will be located closer to the border of the neighbouring plot than the local detailed plan or the City of Helsinki building regulation allow. Constructing a geothermal heat well requires obtaining the neighbour's consent is necessary if the well is less than 7.5 metres away from the border of the plot.

Record the hearing or consent of a neighbour in your project information on Lupapiste.

Frequently asked questions

A neighbour can be a private person, housing cooperative, company, city or some other body that owns or occupies the property.

If two properties share a border, they are neighbours. A property located behind another property is not a neighbour. An exception to this are the so-called axe-handle plots. If between two properties lies a road to a third property, a so-called axe handle, these two properties are neighbours.

A property located immediately on the other side of the road or diagonally opposite is a neighbour. However, a wide road with several lanes severs the neighbour connection. In Helsinki, such roads include Ring I, Itäväylä and other exit roads of the city.

A property located behind a narrow strip of a park is a neighbour. No exact number of metres has been determined for the width of the strip of a park; the matter is assessed case-specifically.

There can be several owners or occupiers of the property. Everyone must be consulted separately. Particular attention should be paid to this issue, for example in the case of property owned by the estate of a deceased person.

The consent and hearing of a neighbour are two different things. If a neighbour does not consent, construction may not be started. In a hearing, neighbours can object to a project, but if the project is in accordance with the local detailed plan, it can still be implemented.

A neighbour can refuse to give their consent, if the project impedes the use of their property. One of the purposes of the permit process is to ensure the equal treatment of neighbouring properties, therefore, a neighbour who refuses to give their consent must give a reason for not consenting.
