Tenants erecting privies. How compensated

(1) In all cases in which the tenant of any land is, by reason of his ownership of any building erected or to be erected thereon, compelled by this Act to provide sufficient water- closet, earth-closet, or privy accommodation for use in connection with such building, and constructs it upon the said land or upon other land of the same landlord so that it is a fixture thereon, the tenant shall, in the event of his tenancy being determined by the landlord, be entitled to payment from the landlord of the value of such water-closet, earth-closet, or privy at the date of the tenancy being so determined, and in the absence of any special circumstances the value of such water- closet, earth-closet or privy shall be assumed to be the cost of and incidental to constructing it, less ten per centum of such cost for each complete year which elapses between the construction and the termination of the tenancy. (2) Any agreement whereby a tenant is sought to be deprived of his right to payment as required by this section shall as to such deprivation be wholly void.
