How zoning works in Las Cruces

Growth pressure in Las Cruces concentrates along the I-25 corridor and toward the Mesilla Valley, with active infill near downtown alongside greenfield subdivision entitlement on the city's east and north edges. Because Las Cruces sits adjacent to New Mexico State University and within commuting range of Fort Bliss and El Paso, residential and mixed-use rezoning requests tied to student and workforce housing are a recurring pattern before the Planning & Zoning Commission.
