What is Rent Control In Scotland?

Legal Definition
Rent control in Scotland is based upon the statutory codes relating to private sector residential tenancies. Although not strictly within the private sector, tenancies granted by housing associations, etc., are dealt with as far as is appropriate in this context. Controlling prices, along with security of tenure and oversight by an independent regulator or the courts, is a part of rent regulation.

Regarding Rent Act legislation, when the legislation deals solely with the law applicable to private sector residential tenancies, the Act usually covers, mutatis mutantis, both Scotland and England and Wales; but when the legislation also covers other matters, it is more customary for separate parallel Acts to be promoted. Examples of the first category are all the pre-1939 war Acts and the Rent Acts of 1957, 1965 and 1974; and of the second, the Housing Act 1980, in Scotland this is the Tenant's Rights Etc. (Scotland) Act 1980; and the Housing Act 1988, in Scotland this is the Housing (Scotland) Act 1988.
