IBS — All Editions

The NAHB International Builders' Show, known as IBS, is organised for residential building professionals and describes itself as the largest gathering of its kind in North America. It is held in Las Vegas each year, and the programme combines an exhibition with education sessions and keynote events.

The 2026 edition took place from 17 to 19 February 2026 at the Las Vegas Convention Center. The 2027 edition is listed for 2 to 4 February 2027, again in Las Vegas, and the organiser's site is already promoting it. According to the organiser, the 2027 education programme offers more than 120 sessions, ranging from headline speakers to hands-on workshops and deep-dive sessions that attendees can tailor to their own business needs.

The organiser's own numbers for the show are 78,000 building professionals, more than 27,000 organisations and more than 1,700 exhibitors. IBS also opens Design & Construction Week with an opening ceremony, and the 2027 headliner announced by the organiser is Kevin O'Leary, who will speak on entrepreneurship, investing, leadership and growth.

Registration is handled through the organiser's site, where the education planner and exhibitor information are also published. TradeShowBuzz tracks the 2026 and 2027 editions, so you can compare dates and plan your trip to Las Vegas ahead of the show.
