NEC Thornydale Rd & Sumter Dr 18.7 Acres of Residential Land Offered at $3,700,000 in Tucson, AZ 85742

Positioned at the northeast corner of Thornydale Road and Sumter Drive in Northwest Tucson, this ±18.5-acre site offers a fully entitled path for a Class-A multifamily or mixed-use community. Located in the Tortolita Planning Area of unincorporated Pima County, the property benefits from established infrastructure and strategic frontage along Thornydale Road, a major arterial connecting Tucson and Marana. The site aligns with Pima County’s Pima Prospers Comprehensive Plan, supporting infill and compact development where utilities and transportation are already in place.
The approved concept envisions a 270-unit community with a mix of one-, two-, and three-bedroom layouts, complemented by an 8,000 SF clubhouse and 3,000 SF of neighborhood-serving commercial space. Thoughtful design integrates 36% open space, dual gated access, pedestrian connectivity, and sustainability features such as rainwater harvesting, LED lighting, and EV-ready parking. Environmental compliance is complete, including Important Riparian Area preservation and offsite mitigation under the Conservation Lands System.
Surrounded by established residential neighborhoods, retail, and employment hubs, the property sits within a high-income submarket with strong fundamentals: vacancy rates near 5%, rent growth exceeding 46% since 2019, and proximity to major employers like Raytheon, Amazon, and Northwest Medical Center. With population growth projected at +1.6% annually through 2030 and average household incomes above $120,000 within five miles, demand for quality housing remains robust.
This offering represents a rare opportunity to deliver a best-in-class multifamily community in a corridor with limited new supply, strong market drivers, and strategic flexibility for future annexation into Marana.
