E Old Hwy 144 - New Harmony Ranch Lot • Terrain commercial • 465,61 Acres • 35 377 499 $ CAD • 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 Interstate 15 in New Harmony, Iron County, approved for a 547-unit master-planned resort community. The Tier III New Village designation, A-20-to-SPA rezone, and Development Agreement with Iron County were secured in 2024 following a unanimous Planning Commission recommendation, vesting development rights across five residential districts plus commercial density in a village center.
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 approximately 13,100 linear feet of 18-inch transmission main tying into an existing CICWCD well with reported surplus capacity, two candidate gravity tank sites, an existing on-site well, and an identified secondary well site. A special service district framework is in place to support buildout.
The current engineered site plan (Go Civil Engineering, 2025) delivers 178 designed homesites in the initial phases, ranging from roughly one-third acre to 2.4 acres, with the balance of the 547-unit entitlement carried in large future development parcels — giving a buyer 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, single-family, and townhome districts, plus a 12-acre village center entitled for 40,000 SF of retail and 80 hotel keys. Planned amenities include a 10-acre lake with lakeshore clubhouse, an event center with pools and courts, equestrian stables and barn with direct BLM trail access, and more than 8 miles of internal trails — all with protected, panoramic views of the Kolob Canyons district of Zion National Park. Highway access is designed with two Hwy 144 access points and UDOT-coordinated acceleration/deceleration lanes. The site lies outside the Utah Prairie Dog clearance area, and preliminary geotechnical work is complete.
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 more than 34% from 2010 to 2020, with 27,000 additional households projected by 2035, and roughly 60% of recent product in northern Washington County has priced above $700,000.
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, geotechnical report, and market study available upon execution of a confidentiality agreement.
