Detached ADUs today

Hampton City Council unanimously adopted a series of ordinances on November 12, 2025 allowing property owners to create accessory dwelling units city-wide, following a Planning Commission and steering-group process that began in mid-2025.

Size cap

The adopted ordinance sets the numeric standards. Because the amendment is only months old, confirm the current cap with Hampton Planning rather than relying on published summaries.

Occupancy rule

Occupancy and owner-occupancy terms were settled in the November 2025 adoption. Confirm the current requirements directly with the city.

Utility notes

Hampton is on public water and sewer. Chesapeake Bay and Hampton Roads floodplain areas affect large portions of the city and drive elevation requirements.

What SB 531 changes

Hampton adopted its ordinance ahead of SB 531's July 1, 2027 effective date, which is the pattern the statute encourages. The fee cap and setback parity provisions will apply regardless.

The Detail

Reading between the lines.

Hampton is the newest entrant. After a steering-group process through 2025, City Council unanimously adopted ADU-enabling ordinances on November 12, 2025, allowing accessory dwelling units city-wide. Hampton framed the change explicitly as a response to its affordable-housing shortage.

Because the framework is so new, the practical standards are still settling into the permitting workflow. That is genuinely an advantage for early movers — staff are engaged with the program, and there is not yet a queue.

The siting picture is dominated by two overlays: Langley Air Force Base AICUZ noise zones, which cover a substantial share of the city, and Chesapeake Bay and Hampton Roads floodplain areas that drive finished-floor elevation. Both are constraints SB 531 expressly preserves, so they will still apply after 2027.
