    (10) A development impact fee ordinance may exempt all or part of a particular development project from development impact fees provided that such project is determined to create affordable housing, provided that the public policy which supports the exemption is contained in the governmental entity’s comprehensive plan and provided that the exempt development’s proportionate share of system improvements is funded through a revenue source other than development impact fees.

    (14) A development impact fee ordinance shall specify when an application for an individual assessment of development impact fees shall be permitted to be made by a developer or fee payer. An application for an individual assessment of development impact fees shall be permitted sufficiently in advance of the time that the developer or fee payer may seek a building permit or related permits so that the issuance of a building permit or related permits will not be delayed.
    (15) A development impact fee ordinance shall provide for appeals regarding development impact fees in accordance with the requirements of section 67-8212, Idaho Code.
    (16) A development impact fee ordinance must provide a detailed description of the methodology by which costs per service unit are determined.

If the number of new service units projected over a reasonable period of time is less than the total number of new service units shown by the approved land use assumptions at full development of the service area, the maximum impact fee per service unit shall be calculated by dividing the costs of the part of the capital improvements necessitated by and attributable to the projected new service units described in section 67-8208(1)(g), Idaho Code, by the total projected new service units described in that section.
    (17) A development impact fee ordinance shall include a schedule of development impact fees for various land uses per unit of development.

    (18) After payment of the development impact fees or execution of an agreement for payment of development impact fees, additional development impact fees or increases in fees may not be assessed unless the number of service units increases or the scope or schedule of the development changes. In the event of an increase in the number of service units or schedule of the development changes, the additional development impact fees to be imposed are limited to the amount attributable to the additional service units or change in scope of the development.
    (19) No system for the calculation of development impact fees shall be adopted which subjects any development to double payment of impact fees.
    (20) A development impact fee ordinance shall exempt from development impact fees the following activities:
    (a)  Rebuilding the same amount of floor space of a structure which was destroyed by fire or other catastrophe, providing the structure is rebuilt and ready for occupancy within two (2) years of its destruction;
    (b)  Remodeling or repairing a structure which does not increase the number of service units;
    (c)  Replacing a residential unit, including a manufactured home, with another residential unit on the same lot, provided that the number of service units does not increase;
    (d)  Placing a temporary construction trailer or office on a lot;
    (e)  Constructing an addition on a residential structure which does not increase the number of service units; and
    (f)  Adding uses that are typically accessory to residential uses, such as tennis courts or clubhouse, unless it can be clearly demonstrated that the use creates a significant impact on the capacity of system improvements.
    (21) A development impact fee will be assessed for installation of a modular building, manufactured home or recreational vehicle unless the fee payer can demonstrate by documentation such as utility bills and tax records, either:
    (a)  That a modular building, manufactured home or recreational vehicle was legally in place on the lot or space prior to the effective date of the development impact fee ordinance; or
    (b)  That a development impact fee has been paid previously for the installation of a modular building, manufactured home or recreational vehicle on that same lot or space.
    (22) A development impact fee ordinance shall include a process for dealing with a project which has extraordinary impacts.
    (23) A development impact fee ordinance shall provide for the calculation of a development impact fee in accordance with generally accepted accounting principles. A development impact fee shall not be deemed invalid because payment of the fee may result in an incidental benefit to owners or developers within the service area other than the person paying the fee.
    (24) A development impact fee ordinance shall include a description of acceptable levels of service for system improvements.
    (25) Any provision of a development impact fee ordinance that is inconsistent with the requirements of this chapter shall be null and void and that provision shall have no legal effect. A partial invalidity of a development impact fee ordinance shall not affect the validity of the remaining portions of the ordinance that are consistent with the requirements of this chapter.
