There are approximately 24,500 housing units (as of January 1, 2010) in York County, over 1,400 of which are military units located in Bethel Manor, the Naval Weapons Station, Camp Peary, Cheatham Annex, and the U.S. Coast Guard Training Center. Single-family detached homes dominate the landscape, representing 70% of the housing stock. However, there are more than 7,100 townhouses, duplexes, apartments, and condominiums in the County, almost 20% of which are on-base military units. Over a third of the new housing built since 1990 has been of the single-family attached and multi-family variety.

Because of the high rate of housing construction in recent years, adding over 9,200 units since 1990, York County's housing stock is relatively young and of good quality. About 16% of the housing units in the County were built within the past nine years (since the 2000 Census was taken), and over a third (37%) were built since 1990.

York County has one of the highest rates of home ownership on the Peninsula, but there is still a significant amount of rental housing. According to the Census Bureau's American Community Survey, rental housing constitutes almost a quarter of the County's occupied housing stock. Over a quarter of this rental housing is on-base military housing. Although commonly associated with apartments, rental housing is not limited to multi-family housing. In fact, apartment complexes account for only about half of the County's private (i.e., non-military) rental housing.
