The housing situation is more favorable in Uruguay than in most Latin American countries. Housing construction, dominated by the public sector, is financed in large part by the Mortgage Bank. The National Institute of Low-Cost Housing builds low-cost dwellings for low-income workers and pensioners. At last estimate, 98% of all housing units were made of durable materials including stone masonry, wood, zinc, or concrete. Owners occupied more than 55% of all dwellings; nearly 25% were rented; less than 20% were occupied by usufructus (households legally inhabiting someone else's living quarters); and about 1% were occupied by members of housing cooperatives. Of all housing units, more than 90% had private toilet facilities, and nearly 75% had water piped indoors.
