House committee substitute to the 1st edition makes the following changes. 

Amends the following two of the five criteria set forth in new GS 160D-1110.1 for the siting and use of certain unaffixed temporary dwelling units (TDUs), including certain recreational vehicles, during construction of a permanent residential dwelling (PRD) on the same parcel to now require: (1) all applications for the construction of PRD have been submitted (was, all permits and approvals for the construction of the PRD have been secured) and (2) placement of the temporary dwelling unit on the subject parcel must now meet setback requirements applicable to that parcel (was, the subject parcel must have the permitted driveway access installed). Specifies that the minimum setback authorized by development regulation for any dwelling within the parcel applies to the temporary dwelling unit. 

Now requires the county to issue a TDU permit upon payment of the fee regardless of the parcel size. Removes authority given to counties to impose the following conditions in issuing a permit: (1) that the parcel be at least one acre in size and (2) that the applicant demonstrate evidence that financing has been secured for the construction of the PRD. In addition to other listed reasons, allows a county to revoke a TDU permit if the local government denies any required permit application submitted for the construction of the permanent residential dwelling. Makes organizational and technical changes.
