Which income limit do I have to meet to get a voucher?

Generally the Very Low Income (50%) limit for your household size, counted on gross annual income of everyone in the household. At least 75% of the vouchers a housing authority issues to new families each year must go to households at or below the Extremely Low Income (30%) limit, so many vouchers go to the lowest-income households. Housing authorities can also have additional requirements and waiting-list preferences.
