IS-OSMTH

Standard for Off-Site Construction Tiny Houses
(IS-OSMTH)

ICC 1215 – Design, Construction, Inspection and Regulation of Small Residential Units and Tiny Houses for Permanent Occupancy

Abstract:  This standard will provide minimum requirements for the design, construction, inspection, certification and regulatory compliance of small residential units (SRUs) and tiny houses used for permanent occupancy to assure public safety, sustainability and resilience. The standard will include: consensus definitions for SRUs, tiny houses and related terminology; prescriptive and performance based compliance methods for SRUs, tiny house foundations and chassis; and plan review, inspection and certification requirements for SRUs and tiny houses constructed on-site and off-site. The standard will address SRUs and tiny houses built on a foundation and those with wheels and a permanent chassis intended for permanent occupancy. The 2021 International Residential Code (including Appendix AQ), and ICC/MBI Standards 1200 and 1205 will serve as the initial base documents with references to other existing standards. The standard will be written in mandatory code-intended language to support use by manufacturers and adoption by jurisdictions globally. This standard will not address SRUs or tiny houses used for temporary or seasonal occupancy, or tiny house community development or microgrids.

Background (Needs Statement):  Tiny houses are growing in popularity as communities look to address affordable housing issues and homebuyers are looking for new housing options. This standard will codify existing requirements for the design, construction, inspection and certification of SRUs and tiny houses used as permanent dwellings into a single standard and address identified gaps in available requirements for foundations and chassis. The 2021 International Residential Code (including Appendix AQ), and ICC/MBI Standards 1200 and 1205 will serve as the initial base documents with references to other existing standards.

Residential Smart Door Committee
(IS-RSDC)

ICC 1425 – Standard for Residential Smart Doors

Project Description:  This standard provides requirements to cover smart doors rated 600V or less to be employed in ordinary locations in accordance with the National Electrical Code, NFPA 70 and the Canadian Electrical Code, Part I, C22.1 and the Standard for Fire Doors and Other Opening Protectives, NFPA 80. This standard sets forth the minimum durability, safety and labeling requirements for smart doors and would test the worst-case smart door with the maximum number of smart accessories on the door / frame system to confirm the maximum input power, temperature test and evaluate for environmental conditions for the certification of the smart door / frame system.

Project Need: A product evaluation standard for powered and connected residential smart doors that can be referenced in the IRC and used by manufacturers to certify to does not exist. The smart door standard would be developed to address topics and features unique to smart doors that are not addressed in existing standards. For instance, when power is physically conveyed from the door frame to the door, the power transfer device should be certified as a component for its rated voltage, current, and the number of door cycles it is capable of handling.
