If you live in an apartment or duplex, we are responsible for the exterior of the building and common areas. You are responsible for your property. You will find more information about this in your rental agreement. A tenant of co-ownership of a dwelling is only entitled to the legal right to renew his lease as the holder of a “long lease” if he has up to 100% of ownership “stairs”. However, the lessor may have its own policy of authorizing the renewal of the lease if there is less than 100% ownership. Tenants should inquire with their landlord. .
