What do you need to know

  • You always need a permit to place a roof structure
  • The permit check gives you clarity about what you need to do or what obligations apply to you. The outcome of the permit check can be:
    • Apply for a permit for 'Construction activity (environmental plan):  
      • the municipality will assess whether your construction or renovation plans comply with the rules in the environmental plan. In the environmental plan, the municipality determines what may happen to the space in the municipality.  
    • Apply for a permit for 'Construction activity (technical)'
      • The municipality will check whether your (re)construction plans meet the technical building regulations.
  • When installing a structure, such as a roof structure, you must always comply with the Living Environment Construction Works Decree.  
  • If your building in protected city view state special rules apply. In Hilversum, the Noordwestelijk Villagebied, Plan Oost and Hilversum Zuid districts are protected
  • If your building has a monument does apply special rules
  • Check whether your building is in a protected cityscape or is a monument
  • Sometimes it is necessary that you also apply for a permit or report for other activities. Make sure you check the rules in time and submit the request or report via the Environment counter. This prevents you from not being allowed to start. See the links under the heading View also

welfare rules

  • Make sure that your application fits within the rules for roof structures in the Welstandsnota. In the welfare note contain the rules about what a building may look like and whether the design fits in with the environment.
  • The welfare memorandum mentions 3 welfare levels:
    1.    deprived and ordinary areas
    2.    special welfare areas
    3.    protected situations
  • If you do not know the quality of your building, you can contact the Public Affairs department, Backoffice team, via 14 035 of environment permit@hilversum.nl
  • Plans that, for example, in terms of dimensions, design and detailing meet the aesthetics rules are usually processed faster

Involve the neighborhood (participation)

  • In Hilversum we recommend that anyone who starts a project (initiators) contact people who live in the area or are involved in another way (stakeholders) at an early stage. That's called participation
  • For example, it may concern residents who want to place a dormer window, but also companies that want to build a new residential area
  • Download the manual Involve the neighborhood (pdf, 256 kb) to know what you need to do, or what may be asked of you when participating
