Prohibits the Department of Environment and Natural Resources from denying, on the basis of the setback requirements in 15A NCAC 7H .0306(a), a development permit for the repair or reconstruction on its original footprint of any residential structure constructed prior to August 11, 2009, with total floor area greater than 5,000 square feet. Requires the Coastal Resources Commission to adopt by October 1, 2011, temporary rules consistent with and substantially identical to that prohibition on development permit denials, which will remain in effect until permanent rules replace them.
