The NoVA ADU Permitting Reality

ADU Permits in Fairfax County, Arlington & Alexandria Are a Bureaucratic Maze

Fairfax County calls them “Accessory Living Units” and caps them at 800 sq ft or 40% of your home. Arlington uses different setback rules. Alexandria has its own design standards. One wrong form delays your project by months.
