Questione giuridica chiave
Whether the property-management contract was tacitly extended to include paid extraordinary renovation-related services.
Decisione estratta
No tacit agreement for additional remuneration was proven; the services remained within ordinary management.
Motivazione estratta
The cantonally established facts showed passive or unnecessary involvement by the manager, while architects and engineers handled the renovation. The manager had never asserted an extra-fee claim during the works and had defined ordinary fees in its 1997 letter.
