[h=2]AS 29.45.070. Mobile Homes.[/h]Mobile homes, trailers, house trailers, trailer coaches, and similar property used or intended to be used for residential, office, or commercial purposes and attached to the land or connected to water, gas, electric, or sewage facilities are classified as real property for tax purposes unless expressly classified as personal property by ordinance. This section does not apply to house trailers and mobile homes that are unoccupied and held for sale by persons engaged in the business of selling mobile homes.
They are not built to the building code requirements so I do not know how you can tell him what modifications need to be done to make it equivalent to a site built.
A 1983 unit is a "manufacture home" and not a "mobile home/trailer house" there is a significant difference between the two standards
If it is on a permanent foundation then a CO could be issued stating that but I would still identify the structure as a manufactured home
