3302 UT-144, New Harmony, UT 84757

New Harmony Ranch is one of the largest fully entitled residential development opportunities in Southern Utah: ±465.61 acres (per county records) at Highway 144 and I-15 in New Harmony, Iron County, approved for a 547-unit master-planned resort community with a County-approved Development Agreement, SPA zoning, and Tier III New Village designation secured in 2024.

The sale conveys the land, all entitlements and vested rights under the Development Agreement, and 297 acre-feet of senior-priority (1934 and older) water rights through the Central Iron County Water Conservancy District — the scarcest input for development in this corridor. Water delivery is already engineered: a 2025 design lays out 13,100 linear feet of 18" transmission main tying into an existing CICWCD well with reported surplus capacity, two gravity tank sites, and an identified secondary well site. The current engineered site plan (Go Civil Engineering, 2025) delivers 178 designed homesites in the initial phases, with the balance of the 547-unit entitlement carried in large future development parcels — a phased path from near-term lot delivery to full master-plan buildout. The next milestone is the grading plan.

The approved program spans estate lots to townhomes plus a 12-acre village center entitled for 40,000 SF of retail and 80 hotel keys, an event center, lakeshore clubhouse, equestrian stables with direct BLM trail access, a 10-acre lake, and more than 8 miles of trails — all with protected, panoramic views of the Kolob Canyons district of Zion National Park.

Positioned one mile west of I-15 between two of the fastest-growing markets in America — 20 minutes to Cedar City and 40 minutes to St. George — the site sits in a corridor where demand has never been the constraint; water and entitlement have been. This offering solves both. Iron and Washington Counties grew 34%+ from 2010–2020 with 27,000 additional households projected by 2035, and roughly 60% of recent product in northern Washington County has priced above $700K.

Offered at $25,000,000 — approximately $45,700 per entitled unit. Full due diligence package including the recorded Development Agreement, current site plan, water transmission design, will-serve letters, and market study available upon execution of a confidentiality agreement.
