Community Overview

Arivaca is a small desert community in southern Pima County, Arizona, roughly 60 miles southwest of Tucson and 11 miles north of the Mexican border. With a median age of 61 years, this is one of Arizona's older communities. The 644 residents live across 196 square miles of Sonoran Desert landscape, making it one of the most spread-out populations in the state.

PO Box Only Mail Service

This is a PO Box Only Zone. There's no alternative mail delivery across the territory. The post office maintains 442 PO Boxes for 334 local households, a ratio of 1.32 boxes per household that indicates regional service extending beyond Arivaca proper. Those extra boxes serve surrounding ranches, off-grid residents, and seasonal property owners scattered across the vast territory.

Rural carrier routes handle the limited street delivery that exists. Two rural routes serve 134 addresses along roads like Hardscrabble Road, Crooked Sky Road, and Jalisco Road. Street names tell the story of Arivaca's character: numbered streets (1st through 6th) mark the historic town center, while ranch roads (Universal Ranch Road, Chilton Ranch Road, Arivaca Ranch Road) and Spanish place names (Camino Colinas Verde, Calle Pimeria, Tres Bellotas Road) reflect the area's ranching heritage and proximity to Mexico.

Housing and Demographics

Mobile homes make up half the housing stock. Of 427 total housing units, 212 are mobile homes. This isn't a planned retirement development but rather an affordable, off-the-grid lifestyle choice for retirees and others seeking quiet isolation. The median home value of $78,700 is well below Arizona averages. Owner-occupancy is high at 78% (259 of 334 occupied units), and only 8% of homes sit vacant seasonally.

Local Economy

With just 14 business establishments and 106 jobs, Arivaca doesn't have much local employment. Most workers commute elsewhere or are retired. The community has a notable Hispanic population of 157 residents (24% of total), and street names in Spanish are common throughout the area.
