This preemption legislation, similar to HB 302, prohibits counties and cities from regulating "building design elements" in single or double family dwellings.  Local governments could no longer enact standards on:

- exterior building color,

- type or style of exterior cladding material, 

- style or materials of roof structures or porches, 

- exterior nonstructural architectural ornamentation, 

- location or architectural styling of windows and doors, including garage doors, 

- the number and types of rooms, and

- types of foundation structures approved under state minimum standard codes.   

In short, if a house meets state minimum standard building codes, it can be built.  Exceptions would apply if the dwellings are in state historic districts; are local, state or national historic landmarks; manufactured homes; or if regulations are adopted as a condition of participation in the National Flood Insurance Program.
