Peculiarities of the state registration of sanitary protection zones in the state land cadastre were studied. There are three types of state registration of sanitary protection zones in the state land cadastre. The first case: simultaneous state registration of the land parcel on which the regime-forming object is located and the sanitary protection zone around it. For this case, three features are systematized: if the right to a land parcel is issued for the first time and the sanitary protection zone has not yet been established around it; if there is a state act on the right of ownership or use of a land parcel, and the information about it is not registered in the state land cadastre; if, for certain reasons, division or unification of previously formed land parcels is carried out without changing their purpose.
The second case: state registration is diluted in time. For this case, two types of specific features are systematized: the land management documentation for the land parcel with the regime-forming object located on it was developed and passed state registration and the data was entered into the automated system of the state land cadastre, while the data on the sanitary protection zone was not updated; data on the land parecel have already been entered in the state land cadastre, but the regime-forming object is not yet available.
The third case: the need to update the data on the sanitary protection zone, while the data on the land parcel remain unchanged. The corresponding case should be the most common, taking into account the modern development of technologies and constant changes in the standards of environmental norms. Its relevance is determined by trends regarding the possibility of changes in the direction of the targeted use of the land plot and rapid adaptation of the company's profile to rapid changes in market conditions.
