[Excerpt] One of the main prerequisites of de-institutionalization for physically disabled people is an effective housing policy. A policy that entails non- discriminatory public works programs, non-discriminatory housing subsidies and non-discriminatory building codes. Non-discriminatory public works programs make sure that in all new construction which is financed and undertaken by any municipal, regional or state government agency barrier-free or universal design principles are enforced. This instrument does not require legislative changes. If the Regional Government of Tenerife, for example, were serious about accessibility in residential construction, they could start already tomorrow by including non-discrimination clauses together with operational definitions of accessibility in their procurement contracts; no bidder would receive a contract without guaranteeing full accessibility of the finished structures.
