Unincorporated Adams County caps how many vehicles you may store outdoors by lot size: two total on lots under one acre, or two per acre up to a maximum of five on lots of one acre or more. Oversized units like motor homes, boats and fifth-wheels count, must sit on
The county's Vehicle Regulations (DSR 4-03-03-02-14) limit outdoor vehicle storage by lot size: on lots less than one acre, a total of two vehicles may be stored outdoors; on lots of one acre or more, two vehicles per acre may be stored, to a maximum of five. Oversized recreational units (motor homes, fifth-wheel trailers, campers, boats) count toward the limit and must sit on an approved asphalt or concrete surface, not in the back yard or landscaping. Oversized commercial vehicles are separately capped at 16,000 lbs. GVW for an accessory Administrative Review Permit; heavier trucks require a Special Use Permit and A-3 zoning.
Code Compliance abates over-count or improperly surfaced storage; exceeding the lot-size vehicle cap can trigger notices and required removal.
