No w Polsce często odnosi się z pogardą do amerykańskiego budownictwa, bo przecież tornado to zdmuchnie i korniki zjedzą.

"Many small-scale, one-story building projects in Nebraska may be designed by persons who are not licensed as architects or professional engineers. The size limit on buildings that can be designed by non-licensed persons is based on three factors:
1) The size of the project in square feet.
2) The occupancy classification of the project as defined in the state building code.
3) The occupant load of the project as calculated in the state building code. "
"International Building Code Classification Group Residential (R-3) – Less than 10,000 sq. ft. structures"
"IBC Group Residential (R-1, R-2, R-4) – Less than 4,000 sq. ft. structures
The following types of residential structures, if 4,000 sq. ft. or larger must be designed by an architect and/or professional engineer.
Hotels, motels, boarding houses or any transient sleeping structures
Permanent dwelling units such as apartment houses, dormitories, fraternities and sororities, monasteries, convents, vacation timeshare properties, and non-transient hotels and motels
Residential care and assisted living facilities designed for more than five but no more than 16 occupants, excluding staff.
Multiple-Unit residences with five or more dwellings"
Więc bez uprawnień można tam zbudować budynek mieszkalny do około 1000m2, max 4 lokale.
Lub hotel, motel itp do 370m2.
Podobnie jest w większości stanów.
