    tiny houseAs interest in tiny houses increases, Pima County has created policy criteria to address the lack of specifics in existing County code. 

    The criteria address both construction and zoning of single-family dwellings no larger than 400-square feet. 

    Pima County Development Services frequently hears from property owners with questions about tiny houses. Previously, tiny houses were considered to be in conflict with some aspects of existing building code. Pima County Development Services, however, has reviewed the code and decided performance adjustments for tiny houses do not pose safety risks for occupants and are appropriate in most circumstances. 

    According to the policy criteria: “Tiny houses shall be built and inspected in accordance with the Pima County adopted building code; The house can be partially or entirely built on-site or off-site. If built off-site, it needs to have been permitted by a recognized agency (jurisdiction with a code approval process similar to that of Pima County), or by an approved fabricator accredited by the International Accreditation Services, Inc., to build tiny houses; The County will waive certain building code minimum standards to accommodate tiny houses in accordance with performance criteria in the ICC Performance Code. The reasoning is that certain minimum standards in the code exist to abate slum housing and to provide safe egress and ingress by fire-fighting personnel for multiple-room larger conventional structures. As these homes are tiny, they provide quicker exiting and occupants are more aware of the physical configuration of the space thereby alleviating fall and means of egress risks.”
