Rented Properties (Fitness) 112. Mr. Clinton Davis asked the Secretary of State for the Environment if he will introduce legislation to require local authorities to impose tests of fitness before a landlord is permitted to let a house or a flat. Mr. Amery No. Local authorities already have power to require the repair of an unfit house that can be made fit at reasonable expense, and by demolition or closing order to ensure that any unfit house which cannot be made fit at reasonable expense is taken out of use.
