From the perspective of the letting landlord that is. Assume common yard to front of some units. Each unit has a set amount of exclusive yard in front of it before the common citculation area begins. Yard and units are open to the public and used for the motor trade. Landord has public liability/buildings insurance. Should tenant have public/employers liability insurance in place? Is it a problem or potential problem or liability for the landlord if these insurances are not in place?
