The First Draft of ICC/THIA 1215 Design, “Construction and Regulation of Small Residential Units and Tiny Houses for Permanent Occupancy” has been posted for public comment with a deadline to receive comments by November 24, 2025.
The Standard Has Been Hijacked By The Small Residential Unit
The original intent was to add chassis provisions to progress tiny houses on wheels as a viable solution for housing and further the progress of Appendix Q Tiny Houses.
The standard has been completely hijacked by the Small Residential Unit ( SRU ) and Tiny Houses has now become an incidental focus.
Definition Of The SRU In The Standard
SMALL RESIDENTIAL UNIT (SRU). A dwelling that is 1200 square feet (111 m2) or less excluding lofts and is constructed as a permanent residential structure with or without a permanent chassis.
There has been a great debate in the OSMTH 1215 committee regarding the Small Residential Unit takeover of the standard which is the agenda of ICC.
Opponents Of The SRU Have Been Ignored
The Small Residential Unit ( SRU) still remains the focus of the standard that places tiny houses, a codified term, as a subcategory under the SRU, a made up term that no one recognizes or even uses even;
Against the written comments of stakeholders that participated in the meetings
Against the opponents at the first CAH Hearing
Against NAHB stating it would tag every IRC house of that size
Against 2 petitions that garnered over 700 signatures against the SRU
Against the ICC analysis that stated that the 1200 square feet limit could result in those houses not regulated by the IRC.
