6.1.1 New Construction and Substantial Rehabilitation Standards

A. All buildings proposed for new construction or substantial rehabilitation with FHA-insured mortgage proceeds must meet or exceed the International Energy Conservation Code (IECC version 2009) or, if greater than 3 stories above grade, the American Society of Heating, Refrigerating and Air Conditioning Engineers Standard 90.1 (ASHRAE 90.1 version 2007) or such later versions of these standards as HUD adopts. These HUD minimum standards do not over-ride or replace existing state or local requirements when such state or local requirements exceed the HUD minimum standards.
