Backyard Chickens in Fairfax County, Virginia

The Fairfax County Answer Depends on Lot Size

Fairfax County treats domestic fowl according to lot size. The county’s official Code Compliance guidance says chickens and other domestic fowl may be kept without a special permit on lots of two acres or more, subject to a ratio of one bird unit per acre.

For chickens, one bird unit equals 32 chickens. Only fowl two months or older count toward that ratio.

What If the Lot Is Smaller Than Two Acres?

The county’s backyard chicken guidance says a smaller property may seek a special permit from the Board of Zoning Appeals. That process involves a public hearing, notice, and property-specific review; approval is not automatic.

Roosters, Coops, and Other Restrictions

Fairfax County says roosters are not permitted except with an agricultural use. Location rules also apply to barns and structures that shelter animals, so the coop location must be checked against the property’s zoning.

HOA covenants can prohibit chickens even when county approval is available. Properties near a Resource Protection Area may also have additional waste-management or land-disturbance constraints.
