At a minimum, the tenant will need a right of access over the common areas of the building and Regulations (as defined lot. Leases of space in Section 6.3): (i) suburban office parks should address the entrytenant’s parking rights. Typi- cally, vestibulestenants are given the right to use a specified number of parking spaces, main lobby and common locker room/shower room which number is calculated on a formula based on the first level rentable area of the Buildingpremises. In the Boston suburban market, parking ratios range from three to five spaces per 1,000 square feet of rentable floor area in the common stairwayspremises. Most landlords will not designate particular parking spaces for particular tenants, elevatorsbut will want the lease simply to provide that the tenant has the right to use the parking facility, sprinkler roomsup to that tenant’s designated number of spaces, mechanical rooms, electric and telephone closets, and the pipes, sprinklers, ducts, conduits, wires and appurtenant fixtures and equipment serving the Premises in common with others, (ii) common walkways and driveways situated upon the Land that are necessary or reasonably convenient for access to the Building, (iii) access to, and use of in common with other tenants ofof the building on a first come, loading 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 receiving areas 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 freight elevatorsthankless 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 applicable legal requirements, and electrical and telephone closets, all subject not to Rules and Regulations then in effect and (iv) if grant parking rights to nontenants. Where access to the Premises at any time includes less than the entire rentable floor area of any floorparking facility is controlled, the common corridorslandlord can control usage through limiting the issuance of passes, vestibulesaccess cards, elevator lobbyor the like. Under these circumstances, lavatories, and freight elevator vestibule located on such floor (collectivelya landlord can more safely undertake to guarantee the availability of the tenant’s allotted spaces.

Many office buildings now feature health clubs, cafeterias, and conference facilities. The tenant’s attorney should make sure that the lease specifically provides that the tenant and its employees will have the right to use Tenant’s Share these facilities on the same basis as other tenants of the Buildingbuilding or office park. In the current labor market, it is advisable to provide that the tenant’s solvent storage capacity 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 480 gallons and access lease usually reserves the landlord’s right to the control areas therefor as more fully provided in Section 12.16 hereof. Tenant shall have 24-houradd to, seven (7) days per week access to the Premisessubtract from, the space where Tenant’s acid neutralization system is located, or change the common central vacuum areas of the building and compressed air systems, control areas for solvent storage, freight loading docks and freight elevators, and the dumpster and/or compactor provided by Landlord in the refuse disposal area, land.
