Occupancy permit and notice

Three reasons separate technical completion from legal completion. A finished building is not yet a usable building.

Reason	Meaning
Taking into use is a separate procedure	it follows construction, it is not part of it
With a building permit, an occupancy permit must be applied for once construction ends	the procedure does not start itself
The procedure checks conformity, not completion	the two are not the same

The practical consequence is uncomfortable: a technically finished building can stall in the procedure where the documentation does not match what was built. That is the substance of this whole branch, and it is covered by the article on construction differing from the design.

As with building, taking into use has two levels, and which applies depends on the building. That division changed on 1 August 2026.

Level	Average duration
Occupancy permit	according to the Ministry of Climate, about a month, sometimes longer
Occupancy notice	on average just over a week

The difference is therefore roughly threefold, and it falls exactly at the moment the client wants to move in. Three weeks of waiting is more tangible to a private client than most procedural distinctions, because it carries rent or a second move.

Two changes reduce the number of procedures rather than the requirements. The substantive requirements stay the same.

Change	For whom
For houses with one or two dwellings, the occupancy permit obligation is replaced by an occupancy notice	for homeowners, the most common case
An occupancy permit no longer has to be applied for separately for each building covered by a building permit	for clients with larger projects

This distinction runs through the whole guide: what is simplified is the paperwork, not the substance. The second row matters particularly on plots with several buildings, where a separate application previously had to be filed for each ancillary building, as covered by the article on several buildings.

One principle, from which everything else follows: construction work must be carried out exactly in accordance with the building design. Every change must be reflected in an amendment design before the occupancy permit.

The procedure therefore does not assess whether the building is good, but whether what was built matches what was permitted. A difference between the design and reality cannot be resolved within the procedure, it has to be resolved beforehand: the occupancy procedure is not where documentation gets repaired.

Three observations about timing add up to one recommendation. Taking into use must be planned early.

Documenting changes happens during construction rather than at its end. A change made in spring that nobody recorded is harder to evidence in autumn than at the moment it was made.

Gathering the necessary documents takes time that is added to the procedure and is not contained in the one-month average. Gathering should begin during construction.

The duration of the procedure itself is known only approximately in advance, because an average is not a promise. A margin belongs in the programme.

The practical recommendation follows from these three: plan taking into use as a separate stage in the construction schedule rather than as an afterthought. Otherwise the building stands unused.

Taking into use is a procedure separate from construction, and it checks conformity with the design rather than the readiness of the building. According to the Ministry of Climate an occupancy permit procedure takes about a month on average and an occupancy notice just over a week, a difference of roughly three times. On 1 August 2026 the occupancy permit obligation for houses with one or two dwellings was replaced by an occupancy notice, and several buildings can now be handled in one procedure.

Four rules: document changes during construction rather than at its end. Reflect every change in an amendment design before applying for the occupancy permit. Plan taking into use as a separate stage in the schedule. Allow for the fact that the average duration does not include gathering documents.
