Housing subsidies are mainly divided in two kinds: supply-side and demand-side subsidies. “Traditional supply-side housing programs include government-built public housing and other so-called “bricks and mortar” subsidies given to the producers of housing, including, for example, subsidized financing, contributions of land and materials, and tax credits and deductions.” Demand-side subsidies, on the other hand, consist mainly of “capital grants and allowances targeted to poor households (…) In the housing sector, capital grants are one-time subsidies to households that they can use to purchase, build, or complete (new or existing) units or to rehabilitate existing units (…) A housing allowance is a regular ongoing subsidy to households that offsets some of the costs of their housing and housing-related services. Allowances can be provided to either owners or renters, and they may be used for new or existing housing.”
