Private use
The private use of goods primarily intended for general use is characterized by being a derogation from the principle of equality in favor of an individual. Private use must be understood as the set of powers of enjoyment that, over a demanial dependency, is possessed by an individual or an administration other than the owner of the property.
Thus, in accordance with the provisions of arts. 75.2 RBEL and 85.3 LPAP, private use is that constituted by the occupation of a portion of the public domain, in a way that limits or excludes the use by other interested parties. This happens, for example, when, on a street or public square, the installation of a kiosk is authorized or the owner of a bar is allowed to place tables and chairs on the street.
To the extent that these cases contradict the primary purpose of public dependency, which is general use, these private uses constitute an abnormal use of the public domain. If, despite everything, they are admitted, it is because the contradiction is not serious, since it only falls on a part of the demanial dependence, and therefore the general purpose to which the good in question is affected can continue to be fulfilled. Consequently, we must not lose sight of the general interest involved in the allocation of the public domain to public use, to which private use must in all cases be subordinated. Furthermore, even if it is a private activity or use, it must also fulfill a purpose of social utility or general interest, the requirement of which must be controlled by the administration.
In any case, the private use of a public asset must have an accessory or secondary, marginal character, with respect to the public allocation of the asset to public use; Otherwise, private use would mean an illegitimate change in the impact of public property, as would happen in the case of authorizing the placement of bar chairs and tables on public roads so that both pedestrian and road traffic would be impossible.
Derived from all of the above, it is easy to assume that the principles of gratuity and freedom typical of general common use do not apply to private uses. On the contrary, private use, both abnormal and normal, justifies the payment of a fee. Likewise, the need to control the compatibility of private use with general use, to which the property is primarily affected, explains that the right to private use can only arise from an express and constitutive act of the administration, through which it assesses the opportunity and convenience of granting it.
The private uses are diverse, depending on whether or not they require the completion of a work that involves the physical transformation of demanial dependency. In the first case, we will talk about occupancy, in the second simply about parking. As for the regime of simple parking lots, which constitute, as has been said, a private occupation of the public domain in favor of an individual, but which do not involve the performance of any important work that causes a physical alteration of the property (chairs and tables in cafeterias on public roads, circus tents, etc.), they require an authorization or administrative license for their exercise and the administration has important powers regarding its granting (discretionality) and renewal (precariousness), and in establishing the conditions that can shape its contents, all of this in order to guarantee the general interests of the conservation and circulation of public dependencies.
Unlike parking lots, occupations involve an abnormal private use, not preventing general use, but requiring a transformation, a definitive work and, therefore, they must be protected by a more solemn and effective title: the concession (arts. 86.3 and 93 et seq. LPAP and 78 et seq. RBEL). Examples of permanent occupations are kiosks on public roads, yacht clubs in the maritime-terrestrial zone, etc.
The procedure for granting public concessions is analogous in nature to the contractor selection procedure and responds to the need to ensure the principle of equal opportunities and the choice of the most suitable project or convenient to the general interests.
