The RV Industry Association’s standards department has released a revised version of the American National Standards Institute Uniform Plan Approval-1 (ANSI UPA) 2019 edition. UPA-1 describes the plan approval requirements to ensure a high degree of safety and health for occupants using RVs.
This revised version contains minor changes reflecting how plans can be submitted to the Authority Having Jurisdiction (AHJ). The AHJ is an organization responsible for approving equipment, installation or procedure. Therefore, it’s important at the beginning of any project that the AHJ(s) be identified by an agency/organization.
Key changes to the UPA-1 include, new provisions addressing floorplans for lofts along with the location of stairways, tread and riser dimensions, handrails and guardrails, ramp doors, generator connections, solar power sources, plumbing low-point drains and traps.
Fire & Life Safety has been enhanced to include ramp doors, and location of stairways. Generator, solar and other alternative power source connections to both low voltage and 120-volt power assembly diagrams have been added to the electrical section of chapter three.
All proposed editorial revisions were considered and finalized by the UPA-1 Canvass Working Committee and RVIA staff, and the revised UPA-1 was approved by the ANSI Board of Standard Review on March 8.
The UPA-1 and accompanying background information is now available and can be purchased here.
