Project licensing

What licensing requirements and procedures apply to construction projects in your jurisdiction (eg, planning consents)?

Works cannot usually be initiated before delivery and entry into force of a construction permit.

During work, a complementary construction permit may be required if changes are made to the initial construction project and, in the absence of any changes, compliance with the permit as well as with regulations for construction works is required (eg, schedules, work during week days and no night work except if authorised).

After completion of the work, delivery of an occupancy permit or certification by an architect is required. If the construction project does not comply with the construction permit, the non-authorised part of the project could be subject to a demolition order and/or to a fine.

Professional licensing and qualification

What licensing requirements and procedures apply to construction professionals, including any required qualifications?

The licensing requirement and procedures applying to construction professionals depend on each canton. Construction professions are not regulated at federal level; however, various formations, studies, certifications and licences exist. Professionals may be part of various federal, cantonal and communal associations and be entered in professional registers. Any party can declare itself to be a general or total contractor, implying the need to run detailed checks on a case-by-case basis before executing these types of contract.

Do any special rules and restrictions apply to foreign construction professionals?

There are no specific rules and restrictions that apply to foreign construction professionals, except for those rules applicable to the hiring of foreign workers.
