House rules

All persons making use of Leiden University buildings and grounds must comply with the general University house rules. These are listed in the Regulations on the Use of University Buildings, Grounds and Other Facilities, and are intended to guarantee order and safety for guests and staff alike.

In addition to the University Regulations, some University locations also have their own house rules. Violation of the local house rules or the University Regulations may lead to exclusion from a building.

Use of university buildings, terrains and other facilities regulation


The Faculty of Science has a number of house rules. The aim of these rules is to guarantee order and safety for visitors and employees in the buildings.

House rules

Leiden University considers a healthy working environment as important. From 1 August 2020, smoking on the premises of Leiden University will be prohibited.

Leiden University, affiliated with the Healthy Universities Network, wants to offer staff members and students a healthy and smoke-free learning and working environment with smoke-free premises. The new policy helps people who want to quit smoking and protects non-smokers from smoke nuisance and passive smoking.

From her responsibility to the community and the environment, FWN has drawn up clear guidelines regarding "Flyers and gluing". This is to keep the current flow of information manageable and to prevent paper waste.

These guidelines are intended for (commercial) organisations and/ or institutes/ departments that want to publish, display or otherwise promote activities within or around the faculty.


Flyers are subject to a general prohibition within the faculty. Placing stands or distributing flyers or advertising brochures, is also prohibited, both inside and outside the FWN buildings.
