About Capstone Homes

Capstone Homes is Flagstaff's dominant local builder, founded in 2007 and building in Flagstaff since about 2009. It is a U.S. Department of Energy Zero Energy Ready Home partner, won a 2017 DOE Housing Innovation Award for a Flagstaff home in Presidio in the Pines, and builds ENERGY STAR® certified homes, a certification level only about 1% of U.S. builders achieve. Homes are engineered for 7,000 feet: spray-foam insulation, 95%+ efficiency furnaces, tankless water heaters, and solar-ready wiring come standard, and every home carries a 1-year workmanship, 2-year systems, and 10-year structural warranty administered by a dedicated warranty team. On dirt-start builds, buyers personalize finishes, cabinetry, counters, flooring, and fixtures, at Capstone's Design Studio.

Why Build New in Flagstaff

Flagstaff is one of the most supply-constrained housing markets in the West: about 73% of the surrounding land is national forest, and the city projects a shortage of roughly 8,000 homes by 2031. Most inventory is resale, much of it decades old, so scarce new construction sells on what old stock can't offer, energy performance engineered for 100-inch winters, a 1/2/10 builder warranty, and finishes you choose instead of inherit. The tax picture helps too: Arizona charges a flat 2.5% state income tax, and Flagstaff's median effective property tax rate is about 0.47%, roughly half the national norm. And unlike resale, new construction is priced by the builder: no bidding wars, no waived inspections, no escalation clauses. You know exactly what you're getting, when it closes, and what it costs.
