Capital costs of utility improvements.

In the event that the costs for capital improvements for a water or sewer system are to be charged to or to be passed through to the mobile home owners or if such expenses shall be required of mobile home owners in a mobile home park owned all or in part by the residents, any such charge exceeding $200 per mobile home owner may, at the option of the mobile home owner, be paid in full within 60 days from the notification of the assessment, or amortized with interest over the same duration and at the same rate as allowed for a single-family home under the local government ordinance. If no amortization is provided for a single house, then the period of amortization by the municipality, county, or special district shall be not less than 8 years. The amortization requirement established herein shall be binding upon any municipality, county, or special district serving the mobile home park.
