Omgevingswet (OZON)
The Omgevingsloket is the central place where digital information about the physical living environment under the Omgevingswet comes together; it is part of the Digital System for the Environment and Planning Act (DSO) and includes Rules on the Map, the permit check, submitting applications and notifications, and tailored-measures guidance. Beneath those screens sits Ozon: the object-oriented disclosure of environmental documents. Ozon validates, registers and discloses the content of environmental documents from central government, provinces, municipalities and water authorities, drawn up to the STOP/TPOD standards and the IMOW information model, and offers them through APIs for presentation, visualisation and applicable-rule retrieval. A rule is therefore not just text, but an object annotated with things like activity, location and area designation.

What this source does not give you
Ozon provides the published rules, not their explanation and not the outcome of a case: no explanatory memoranda, no case law, no permit decisions and no answer to whether something is allowed in your situation. Anything a competent authority has not published, or has not published correctly to the standard, does not exist in Ozon — so coverage and currency depend on the authority itself. The APIs are also not freely callable: an API key is required.

Frequently asked questions
- What is the difference between the Omgevingsloket and Ozon?
- The Omgevingsloket is what a person sees: the website with Rules on the Map, the permit check and the application form. Ozon is the registry underneath it, which discloses environmental documents in an object-oriented way and makes them available through APIs. We retrieve the rules from Ozon, so that an answer traces back to the same published text the portal shows, rather than to an internally retyped copy.
- Do I get only national rules, or also those of my municipality and water authority?
- All four tiers of government. Ozon discloses the environmental documents of central government, the provinces, the municipalities and the water authorities — so including your municipality's environmental plan, the provincial by-laws and the water-authority by-laws. That is exactly why this source carries so much weight within the Omgevingswet system: the rules that determine your situation are more often decentralised than found in the national building decree.
- Is what I see here the official promulgation of a rule?
- No. Environmental documents are promulgated through the national publication facility; Ozon discloses their content in an object-oriented way so that it can be queried per activity and location. For the formal published text and the date of entry into force, the official publication remains authoritative. For the question of what applies now and where, Ozon is the practical entry point.
- Why is a rule sometimes missing where I expect one?
- Because Ozon depends on what the competent authority publishes, and how. A rule that has not been supplied, not yet supplied, or not supplied to the STOP/TPOD and IMOW standards cannot be queried as an object. An empty result is therefore not proof that no rule applies; it is a reason to check with the municipality, province or water authority what has actually been adopted.
- Which PrudAI products use this source?
- LEO, VERA and BEVER query the environmental rules live at the source. Within LEO the source is linked to administrative law, tenancy law, corporate law and real-estate law — the areas where an environmental plan or by-law determines the answer rather than merely colouring it.
