Questione giuridica chiave
Whether local housing scarcity in Fribourg opened the way to challenge the initial rent under Art. 270(1)(a) CO.
Decisione estratta
No. The cantonal court correctly found that the circumstances did not establish a qualifying local scarcity creating contractual constraint for the tenant.
Motivazione estratta
The relevant scarcity assessment must be sufficiently current and locally differentiated. The Fribourg statistics and cantonal ordinance were too global and not regionally specific; the urban vacancy rate did not support a finding of concrete constraint.
