Leases frequently contain a covenant by the lessee to bear and pay rates, taxes, assessments and other " impositions " or " charges," or " duties " or " outgoings," or " burdens " (except property tax) imposed upon the demised premises during the term.
The component parts of a lease are the parties, the recitals (when necessary) setting out such matters as the title of the lessor; the demise or actual letting (the word " demise " is ordinarily used, but any term indicating an express intention to make a present letting is sufficient); the parcels in which the extent of the premises demised is stated; the habendum (which defines the commencement and the term of the lease), the reddendum or reservation of rent, and the covenants and conditions.
The Conveyancing Act 1881 provides that, as regards conveyances subsequent to 1881, unless a contrary intention is expressed, a lease of " land " is to be deemed to include all buildings, fixtures, easements, &c., appertaining to it; and, if there are houses or other buildings on the land demised, all out-houses, erections, &c., are to pass with the lease of the land.
Thus a lessee is under an implied obligation to treat the premises demised in a tenant-like or " husband-like " manner, and again, where in a lease by deed the word " demise " is used, the lessor probably covenants impliedly for his own title and for the quiet enjoyment of the premises by the lessee.
A covenant by the lessor, limited to his own acts and those of persons claiming under or through him, for the "quiet enjoyment" by the lessee of the demised premises, and covenants by the lessee to pay rent, to pay taxes, except such as fall upon the landlord, to keep the premises in repair, and to allow the landlord to enter and view the condition of the premises may be taken as typical instances of " usual " covenants.
