It is an affirmative defense to prosecution for trespass in a building or vehicle that the entry, use or occupancy is for an emergency in the case of immediate and dire need, and the person contacts the owner or owner’s agent within 15 days after entering or using the property, or, if the owner is unknown, contacts the city police department, and makes a report of the time of entry, use or occupancy of the property and any damage to the property, unless a notice waiving the necessity for such report is posted on the property by the owner or the owners’ agent. (Ord. 06-46 § 4, 2006; prior code § 13.70.020)
