Questão jurídica principal
Whether the renovation works in the two apartments were subject to authorization under the LDTR or were mere maintenance works.
Decisão extraída
The works went beyond ordinary maintenance, improved the existing comfort, and were therefore renovation works requiring authorization.
Fundamentação extraída
Given their scope, cost, and effect on rents, the works amounted to an almost complete refurbishment and could not be justified solely by wear and tear or tenant damage; the cantonal court's view was not arbitrary.
