Are tiny houses under residential or RV code?

We can build a tiny house for residential code, or to RV code! RV style Tiny SMART Houses are built to meet and (usually exceed) RV standards, and we build them to meet Oregon DOT as well as the Oregon Building Code Standards. Each house is fully inspected to ANSI safety standards by an RVIA inspector and certified as legal Recreational Vehicles. Foundation ready Tiny SMART Houses are built to suit residential codes and zoning for the property they will be placed on.
