WV HB4732

Requires West Virginia municipalities to allow at least one accessory dwelling unit (ADU) by right on any lot containing a single-family dwelling, with ADUs limited to 75% of the primary dwelling's floor area or 1,000 square feet, whichever is less.

Prohibits municipalities from requiring additional parking, owner occupancy, matching exterior design, impact fees, or imposing more restrictive setbacks and height limits on ADUs than apply to the primary dwelling.

Allows municipalities to charge a one-time application fee of up to $250 per ADU, plus standard building permit fees, and to regulate short-term rentals separately.

Mandates that zoning regulations allow ADUs as permitted use on at least 35% of residentially-zoned lots and requires manufactured housing to be treated the same as conventional housing in zoning districts.

Takes effect January 1, 2027, with any non-compliant municipal regulations becoming void on that date; building codes, fire codes, and public health regulations remain in force.
