The Town Manager, or their designee, shall publish and present an annual report to the Select Board quantifying the number and location of building permit applications for new and major renovation projects exceeding 50% of the original gross floor area of the principal dwelling; the number of new and major renovation projects requesting a waiver from this chapter, the disposition of those waivers, the reasons for granting or denying those waivers and the square footage of each project for which a waiver is granted.
C. 
The Select Board may adopt additional requirements, exemption, and regulations to implement or enforce said new fossil fuel infrastructure restrictions in major construction, consistent with this chapter.
A. 
The Building Commissioner may grant a waiver from the requirements of this chapter in the event that compliance with the provisions of this chapter makes a project financially infeasible or impractical to implement. Compliance with this chapter may be considered infeasible if, without limitation:
a. 
As a result of factors beyond the control of the proponent, the additional cost of the project over the long term, including any available subsidies, would make the project commercially unviable; or

Technological or other factors would make the project unsuitable for its intended purpose.
B. 
Waivers from compliance with this chapter may be subject to reasonable conditions. Where possible, waivers shall be issued for specific portions of a project that are financially infeasible or impractical to implement under the requirements of this chapter, rather than entire projects.
C. 
Waiver requests shall be supported by a detailed cost comparison, including available rebates and credits. A waiver request may be made at any time and may be based upon submission of conceptual plans.
