All ADU guides West Virginia ADU code path
Can you build an ADU in West Virginia?
West Virginia municipalities must allow at least one attached, detached, or internal ADU by right, while safety, utilities, flood, access, and objective site standards continue to apply.

The state-wide starting point.
These fields stay separate because a broad state policy, a limited geographic mandate, and a property-specific approval are not the same answer.

Municipal objective standards may apply within the act
Municipal rules remain subject to the act
The act limits local prohibitions
Confirm local rental and short-term rules
What the headline does not settle.
These are the common edges that can move a project outside the protected or simplest path.
State ADU protection does not waive building, fire, health, environmental, utility, or private-title requirements.
Local objective standards still matter and may differ among municipalities.
A second unit, larger unit, short-term rental, or separate sale may follow a different rule than the protected baseline.
What decides the actual lot.
State law is one layer. These checks turn it into a parcel-specific feasibility answer.
- Zoning district, legal principal dwelling, and the municipality's current ADU ordinance
- Lot coverage, setbacks, height, access, parking, and any nonconforming structures
- Sewer or septic capacity, water service, utilities, and fire access
- Wetlands, flood hazard, coastal, wildfire, historic, HOA, deed, and condominium restrictions
A practical verification path.
Stop at the first unresolved layer rather than designing past a constraint.
Confirm the parcel, governing municipality, zoning district, and legal use of the primary home.
Choose an internal, attached, or detached concept and test it against the controlling size and dimensional rules.
Retrieve the current zoning text, permit checklist, utility records, and every overlay that applies to the site.
Resolve wastewater, building, fire, access, environmental, and private-title constraints before final design.
Submit the required plans, complete inspections, and obtain every approval and occupancy document before use.
