Any structure that is more than one story, or is attached to another structure, or is larger than the following square footage limitations shall require a foundation designed by a Colorado registered Professional Engineer.
Prefabricated steel buildings regardless of size require a stamped-engineered foundation and building design.
Zoning Regulations will need to be met, regardless of the structure size.
