Stafford in one screen.
- Administrative Application & Agreement — no public hearing required
- Size capped at 25% of the principal dwelling's gross floor area
- Rental use prohibited today; family, guest or domestic-staff occupancy only
- One accessory dwelling per lot; shares the main home's address
Reading between the lines.
Stafford's accessory dwelling framework is a pre-SB-531 artifact. You can get approval administratively — no public hearing — but the permitted uses are narrow: a family member apartment, a guest house for occasional visits by family or friends, or maid's quarters. The owner signs a notarized agreement accepting those conditions.
That framing has real consequences. The unit may not be rented, it shares the principal dwelling's address, and if it sits inside the main house the entry and design must preserve the appearance of a one-family residence. At 25% of the principal dwelling's gross floor area, the size ceiling is also the tightest we work with in the region.
Stafford is therefore a county where timing matters. SB 531 explicitly forbids family-relation requirements and does not permit an outright ban on ADU rentals — localities may only require minimum 30-day lease terms. Stafford's ordinance will almost certainly have to change before the July 1, 2027 effective date. If your goal is rental income, plan around that window.
Stafford answers.
Can I rent out an accessory dwelling in Stafford County?
+
Not under the current ordinance. Stafford's accessory dwelling agreement limits occupancy to family members, occasional guests or domestic staff and explicitly prohibits rental use. SB 531 should force this to change by July 1, 2027.
How big can a Stafford County accessory dwelling be?
+
No more than 25% of the total gross floor area of the principal dwelling — the tightest ratio among the Northern Virginia jurisdictions we track.
Does Stafford require a public hearing for an accessory dwelling?
+
No. Stafford uses an administrative Application & Agreement filed with the Zoning office, including a notarized owner agreement accepting the permit conditions.
