Questione giuridica chiave
Whether the keeping of many dogs required a building permit as a change of use.
Decisione estratta
Yes. Keeping a large number of dogs can have spatial and environmental effects that make it subject to building-permit control, even without structural works.
Motivazione estratta
A use change needs a permit when it can produce locally perceptible effects on land-use planning, infrastructure, or the environment. Hobby dog keeping with around nine or more dogs is sufficiently impactful to justify prior review.
