Champaign County regulates tiny homes differently based on whether they are on a permanent foundation or on wheels. Zoning and minimum square footage requirements apply.
Champaign County classifies tiny homes based on construction type. Foundation-built tiny homes are treated as standard dwellings and must meet local building codes including minimum square footage (often 400 to 800 sq ft). Tiny homes on wheels (THOW) are typically classified as RVs or mobile homes with different zoning restrictions. Appendix Q of the IRC provides building standards for tiny houses under 400 sq ft. ADU ordinances may provide a pathway for tiny homes as secondary dwellings. Utility connections, septic/sewer, and foundation requirements apply. Some jurisdictions have created specific tiny home zoning districts or overlay zones.
