In this article, we study shape optimization problems involving the geometry of surfaces (normal vector, principal curvatures). Given ε>0 and a fixed non-empty large bounded open hold-all B⊂Rn, n⩾2, we consider a specific class Oε(B) of open sets Ω⊂B satisfying a uniform ε-ball condition. First, we recall that this geometrical property Ω∈Oε(B) can be equivalently characterized in terms of C1,1-regularity of the boundary ∂Ω=∅, and thus also in terms of positive reach and oriented distance function. Then, the main contribution of this paper is to prove the existence of a C1,1-regular minimizer among Ω∈Oε(B) for a general range of geometric functionals and constraints defined on the boundary ∂Ω, involving the first- and second-order properties of surfaces, such as problems of the form:
