‘Sec. 1. 22 MRSA §2502 is enacted to read:
§ 2502. Camping in parking facilities prohibited
A person may not park or occupy a recreational vehicle, as defined in Title 10, section 1432, subsection 18, in a commercial parking facility overnight. For purposes of this section, "commercial parking facility" means a parking structure or area open to members of the public for the purposes of parking their vehicles while patronizing one or more commercial establishments, but does not include a mobile home park or recreational vehicle park allowed by a municipality or a camping area licensed by the department. A person who violates the provisions of this section commits a civil violation subject to a fine of no more than $100, which must be suspended for the first violation and may be suspended for subsequent violations. This section may be enforced by the department, a municipality, a law enforcement agency or a law enforcement officer. Nothing in this section preempts a municipality's existing enforcement authority or prohibits a municipality from adopting a zoning or municipal ordinance with more stringent standards. For the purposes of this section, "law enforcement agency" has the same meaning as in Title 25, section 3701 and "law enforcement officer" has the same meaning as in Title 29-A, section 101, subsection 30.’
