Deviating from the Zoning Plan in Leiden
In Leiden, you can obtain permission from the Municipality of Leiden to deviate from the zoning plan for construction or usage changes that do not align with the applicable rules. This is useful for minor adjustments in the historic city center or around the university campus, and you apply for it via an environmental permit. This keeps spatial planning flexible without immediately amending the plan.
Why Deviate in Leiden?
The zoning plan in Leiden determines what is permitted on a plot, such as residential use in the Maresingel neighborhood or retail on Breestraat. For deviations—like adding an extra floor to a student house or temporary use of a building—this provides a quick solution. It saves time and money compared to revising the plan. Following the Environment and Planning Act effective 1 January 2024, existing plans remain in force under transitional provisions until replaced by an environmental plan.
Legal Basis
Rules on deviations are found in the Spatial Planning Act (Wro) for older cases and the Environment and Planning Act (Ow) for newer ones. Key provisions:
- Article 2.12 General Provisions for Environmental Permits Act (Wabo): Environmental permit contrary to the plan (transitional provisions).
- Articles 5.1 and 5.2 Decree on Quality of the Living Environment (Bkl): "Minor deviation" rules for small changes under the Ow.
- Article 4.7 Environment and Planning Act: For temporary deviations.
- Article 3.14 Spatial Planning Act (former): Standard and structural deviations.
The Municipality of Leiden, as the competent authority, approves only with a sound spatial justification and without conflicting with higher rules such as national policy.
