1. (a) Each regulatory agency shall consider the approval, disapproval, or conditional approval of an application for a permit solely on the basis of any orders, regulations, ordinances, rules, expiration dates, or other properly adopted requirements in effect at the time the original application for the permit is filed.
2. (b) If a series of permits is required for a project, the orders, regulations, ordinances, rules, expiration dates, or other properly adopted requirements in effect at the time the original application for the first permit in that series is filed shall be the sole basis for consideration of all subsequent permits required for the completion of the project. All permits required for the project are considered to be a single series of permits. Preliminary plans and related subdivision plats, site plans, and all other development permits for land covered by the preliminary plans or subdivision plats are considered collectively to be one series of permits for a project.
3. (c) After an application for a project is filed, a regulatory agency may not shorten the duration of any permit required for the project.
4. (d) Notwithstanding any provision of this chapter to the contrary, a permit holder may take advantage of recorded subdivision plat notes, recorded restrictive covenants required by a regulatory agency, or a change to the laws, rules, regulations, or ordinances of a regulatory agency that enhance or protect the project, including changes that lengthen the effective life of the permit after the date the application for the permit was made, without forfeiting any rights under this chapter.
