The current (2016) State Building Code (SBC) does not contain any provisions specific to tiny houses.
There are three broad scenarios to consider:
- A tiny house which is trailer mounted and portable: Would not be subject to the requirements of the SBC.
- A tiny house which is semi-permanent, in that they are chassis/trailer-based but connected to onsite electrical, water and/or drainage services: Would be subject to the requirements of the SBC. If it meets the definition of “Manufactured Housing as Dwellings” would be reviewed and inspected as such; if not, would also require all elements to be reviewed and rough inspections made.
- A permanently located tiny house, not on a chassis/trailer, would be subject to the procedural and technical requirements of the SBC.
As the extent to which the SBC requirements would apply to tiny houses is not currently restricted, we are mindful of the impact this would have on this developing market and would therefore consider allowing, by modification, use of provisions from the International Code Council’s 2018 International Residential Code Appendix Q, which relaxes various requirements in the code as they apply to tiny houses that are 400 square feet in area or less.
It is always best to check with your local jurisdiction of interest to ask if any additional requirements are needed.
