The federal government is attempting to make modern low-cost homes available to poorer families, supplying them with amenities such as piped water, sewerage systems, and electricity. The Ministry of Housing constructed about 4,000 houses for free distribution to poor families between 1978 and 1981. In 1993, government spending for housing was at about 30% of the total budget. In 1995, the Abu Dhabi Department of Social Service and Commercial Buildings (est. 1976) began construction of 504 residential buildings and had 417 other projects in the planning stages. The department has built over 40,000 housing units since 1976. In 1980, 33% of all housing units were flats, 30% were traditional Arabic dwellings, 9% were low-cost housing, 8% were shacks, and the remainder were sheds, caravans, single rooms, tents, and other facilities. About 85% had water closets and 26% had electricity, piped-in water, and access to a sewage system.
