Tiny home rules in West Des Moines, IA — covering tiny houses on wheels (THOWs), park model RVs, and tiny home on foundation builds — determine where they are legal and how they get permitted.
Iowa Code Chapter 103A establishes a statewide building code that applies to permanent tiny homes. Cities under 15,000 population must follow the state code as adopted, while larger cities may adopt equal or stricter standards. Tiny homes on permanent foundations follow IRC Appendix Q standards.
The Iowa State Building Code Commissioner adopts the International Residential Code (IRC), and Iowa has incorporated IRC Appendix Q for dwellings of 400 square feet or less. Permanent tiny homes must meet minimum ceiling height, egress, smoke alarm, and stairway requirements. Cities with populations of 15,000 or more must adopt a building code at least as stringent as the state code. Cities under 15,000 default to the state code. Tiny homes on wheels are regulated as RVs or manufactured homes, not site-built dwellings, and cannot be used as permanent residences except in licensed RV parks or manufactured home communities.
Building tiny homes that do not meet the State Building Code requirements may result in stop-work orders, denial of certificates of occupancy, removal orders, and civil penalties imposed by local building officials.
