If a home on wheels has internal plumbing, it must be connected to potable water and sanitary sewer services as follows:
Water connections may be made through a yard hydrant or an antisiphon hose bib from an existing home on the lot, with connections from the vehicle to the hose bib made with a flexible hose rated for potable water; and
Sewer and sanitary connections may be made through a permitted sewer lateral clean out from the sanitary sewer line of an existing housing unit on the property.
If a home on wheels does not have internal plumbing, the occupants must have access to potable water, toilets, and showers in an existing housing unit on the lot.
Cities and counties must enforce standard inspection procedures for utility hookups to homes on wheels. Cities and counties may not require inspection of the home on wheels itself.
