Housing is considered affordable when rent or mortgage, plus utilities, is no more than 30% of a household’s gross income. As housing costs have risen dramatically in Arlington and throughout the Washington Metropolitan Area, many people who live and work here can no longer afford adequate housing. The County works to preserve Affordable Housing in the community and to provide rental assistance to help low-income residents afford housing.
Types of Affordable Housing
There are two types of affordable units in Arlington.
- Committed Affordable Units (CAFs): These units are guaranteed by agreement with the federal, state, or County Government, or through mechanisms such as tax-exempt financing, to remain affordable to low and moderate income households for a specified period of time; generally 30 to 60 years. Rents in most cases are affordable to households earning 60% or less of the Area Median Income, although some CAFs have rents affordable to households earning up to 80% of median.
- Market-Rate Affordable Units (MARKs): These units are owned by the private market and tend to have higher monthly rents. Affordability fluctuates with factors impacting housing market conditions, including employment trends, economic stability and basic supply and demand. Rent prices are at 50-60% and 60-80% of Area Median Income.
The County works to expand the supply of Committed Affordable Units (CAFs) for low- and moderate-income households. There are more than 8,000 built or approved CAFs in 70+ apartment complexes located throughout Arlington, nearly 15 percent of all apartments in the County.
The Department of Housing and Urban Development (HUD) estimates median family incomes each year, and these determine eligibility limits for affordable housing units. View the current income and rent limits for Committed Affordable Units in Arlington.
