Operating permit for classified establishments ('commodo/incommodo')

This page was last modified on 26-06-2017

Operating permits for classified establishments define the development and operating conditions deemed necessary to protect the environment and ensure the safety of workers, the public and the neighbourhood in general.

The different types of establishments and activities are divided into several classes (1, 1A, 1B, 2, 3, 3A, 3B and 4).

These establishments, previously classified as dangerous, insalubrious or problematic, must be authorised based on their classification by:

  • the minister responsible for the environment (classes 1B and 3B);
  • the minister responsible for labour (classes 1A and 3A);
  • the abovementioned two ministers (classes 1 and 3);
  • the mayor of the commune in question (class 2).

Class 4 establishments are governed on the basis of the applicable specific Grand-Ducal regulation.

Carry out your procedure:

Who is concerned

Natural persons or legal entities who intend to operate an establishment or engage in an activity listed in the nomenclature of classified establishments must obtain an operating permit for classified establishments.

The classified establishments concerned include:

  • activities: vehicle repair and maintenance workshops, butcher's shops, joiner's workshops, bakeries, breweries, laundries, printing shops, restaurants, etc.;
  • establishments: office buildings, underground car parks, care centres, service stations, swimming pools, etc.;
  • technical installations and depots: combustion installations, lifts, electromagnetic wave transmitters, transformer stations, depots of chemical products, etc.

An operating permit for classified establishments may be required for the following:

  • construction and operation;
  • extensions and transformations;
  • substantial changes to the establishment in question;
  • transfers of an activity or equipment to another location (the permit relates to the land registry plot and not to the business operator).

Holders of operating permits must keep themselves informed of legislative and regulatory developments, as existing equipment or activities on the operating site may become subject to a permit in accordance with changes in the law on classified establishments.

In addition, a new permit is required when:

  • operation has not started within the deadline set by the authorisation order;
  • operation is interrupted for 3 consecutive years;
  • the establishment was destroyed or put out of use as a result of an accident.

How to proceed

Preparing the application

Applicants concerned by classes 1, 1A, 1B, 2, 3, 3A and 3B can complete their application for a classified establishment operating permit via the MyGuichet assistant and then print and sign the application before sending it to the competent authorities with the requested annexes.

All applications for operating permits for classified establishments must include:

  • an extract from the land register that is less than 12 months old indicating the neighbouring plots within a 200-metre radius;
  • an extract from a topographical map (scale 1:20,000 or less) enabling the planned location to be identified;
  • a detailed scale map of the establishment indicating the layout of the premises and the location of the installations in particular.

A certain number of specialised intermediaries (engineers, architects, etc.) can offer assistance with regard to the formalities to be completed with the administrations.

Inquiry procedures applicable to the different classes

Each element of the nomenclature of classified establishments is attributed a class (1, 1A, 1B, 2, 3, 3A, 3B or 4) which determines the applicable authorisation procedure.

When a permit application relates to establishments that fall under several classes, the application will be processed:

  • according to the procedure for class 1:
    • when the permit application relates to at least one class 1 establishment;
    • when the permit application relates exclusively to one or more class 1A establishments as well as to one or more class 1B establishments;
    • when the permit application relates exclusively to one or more class 1A establishments as well as to one or more class 3 or 3B establishments;
    • when the permit application relates exclusively to one or more class 1B establishments as well as to one or more class 3 or 3A establishments;
  • according to the procedure for class 1A when the permit application relates exclusively to one or more class 1A establishments as well as to one or more class 3A establishments;
  • according to the procedure for class 1B when the permit application relates exclusively to one or more class 1B establishments as well as to one or more class 3B establishments;
  • according to the procedure for class 3 when the permit application relates exclusively to class 3 establishments as well as to either class 3A or class 3B establishments.

Applicants can ask about the status of their application and request a meeting while the inquiry and decision-making procedure is ongoing, but not during the public inquiry.

Special cases

For some class 1, 1A and 1B classified establishments, an environmental impact assessment (EIA) and/or a risk assessment as well as a safety report concerning the safety of employees, the workplace and the public may be requested.

Where this is the case, the time permitted for checking applications will be longer (90 days instead of 45 for the first check; 40 days instead of 25 for the second check).

Furthermore, where a project is likely to have a significant impact on the population and/or environment of another State, the application is sent to that State as soon as possible and no later than at the time of the public inquiry.

The authorities and public concerned within the State in question therefore have the opportunity to express their opinion on the matter, if possible during the public inquiry and before the competent authority makes its decision.

The State in question shall then be informed of the decision taken with regard to the permit application.

Appeals

The applicant can lodge an appeal against an administrative or ministerial decision with the administrative tribunal:

  • within 40 days following the date of acknowledgement of receipt of the final decision;
  • against the "silence" of the administrations after the different deadlines for the verification of the application and the notification of the decision have expired.

Construction and operation on classified establishments

Construction and operation on classified establishments may only be carried out after obtaining the authorisation order(s).

Operating permits for classified establishments do not release the operator from the obligation to obtain other authorisations required pursuant to other legal provisions applicable for different matters, particularly as regards the acquisition of land or a building:
