Appurtenant Rights. The Tenant shall have, as appurtenant In addition to the Premises, the nonexclusive right to use and occupy the premises, the tenant will want the lease to specify its rights with respect to the property in which the premises are located. At a minimum, the tenant will need a right of access over the common areas of the building and lot. Leases of space in suburban office parks should address the tenant’s parking rights. Typi- cally, tenants are given the right to use a specified number of parking spaces, which number is calculated on a formula based on the rentable area of the premises. In the Boston suburban market, parking ratios range from three to five spaces per 1,000 square feet of rentable floor area in the premises. Most landlords will not designate particular parking spaces for particular tenants, but will want the lease simply to provide that the tenant has the right to use the parking facility, up to that tenant’s designated number of spaces, in common with othersother tenants of the building on a first come, first-served basis. The tenant wants to be sure that it will always have access to its full allotment of spaces. As a compromise, leases often provide that the tenant has the “exclusive” right to its share of parking spaces, but that those spaces are “unas- signed.” This approach leaves unstated the tenant’s rights and remedies if it routinely finds that its allocated number of spaces are unavailable. Landlords understandably do not wish to become entangled in the expensive and thankless task of policing the use of an open parking lot. Sophisticated (i.e., hardened by experience) landlords may simply covenant to maintain an overall number of spaces serving the office building or complex, subject to reasonable rules applicable legal requirements, and not to grant parking rights to nontenants. Where access to the parking facility is controlled, the landlord can control usage through limiting the issuance of general applicability passes, access cards, or the like. Under these circumstances, a landlord can more safely undertake to occupants guarantee the availability of the Building from time tenant’s allotted spaces. Where the premises do not include lavatory facilities, the lease should give the tenant the appurtenant right to time made by use the Landlord of which common lavatories on the Tenant is given notice: (i) the entry, vestibules and main lobby floor or floors of the Building, first floor mailroombuilding containing the premises. Generally, the tenant should have the right to use all common stairwaysareas and facilities of the building, such as elevators, elevator xxxxx, boiler room, elevator rooms, sprinkler rooms, mechanical rooms, electric and telephone closets, janitor closetslobbies, loading docks and bays, rooftop mechanical penthouses and shafts to the extent they house Building equipmentdocks, and the pipeslike. Many office buildings now feature health clubs, sprinklers, ducts, conduits, wires and appurtenant fixtures and equipment serving the Premises in common with others, (ii) common walkways and driveways necessary or reasonably convenient for access to the Building, (iii) access to loading area and freight elevator subject to Rules and Regulations then in effectcafeterias, and (iv) if conference facilities. The tenant’s attorney should make sure that the Premises at any time include less than lease specifically provides that the entire rentable floor area tenant and its employees will have the right to use these facilities on the same basis as other tenants of any floorthe building or office park. In the current labor market, it is advisable to provide that the tenant’s employees and contractors have the right to enjoy tenant’s appurtenant rights under the lease, since many people who formerly would have been employees now legally constitute contractors. The landlord’s form of lease usually reserves the landlord’s right to add to, subtract from, or change the common toilets, corridors, vestibules, areas of the building and elevator lobby of such floorland. Tenant shall have 24 hour, seven day per week access to the Premises, freight loading docks and freight elevators, The tenant should insist that this right be subject to the provisions of this Lease and interruption for External Causes, casualty and condemnation.
