Oro Valley's Prop 431 Sets the Rules for the Town's Next Ten Years
Oro Valley's Prop 431 general plan went to voters November 3, 2026. Its limits on building height, housing goals and open-space policy, and what owners gain.
The general plan on Oro Valley's November 3, 2026 ballot drew no formal arguments for or against. It still decides how tall new buildings get, what housing gets built and which open land stays open.
The publicity pamphlet the Town of Oro Valley mailed to every household with a registered voter has two pages set aside for arguments for and against Proposition 431. Both say the same thing: "None were submitted." Nobody filed a formal case for or against the measure that sets the town's land-use and growth policy until about 2036. Voters approved it on November 3, 2026: Pima County's completed count shows 20,759 yes votes to 5,387 no, about 79 percent in favor. The result becomes official when the canvass is adopted. For an owner, the result decides the document the Town will hold the next rezoning request down the street against.

What Was on the Ballot
Proposition 431's official title is "Oro Valley's (OV) Path Forward General Plan." The ballot text says a yes vote approves the plan to guide the Town for the next 10 years. A no vote leaves the 2016 plan, Your Voice, Our Future, in effect until voters approve a new one. Arizona requires each city and town to adopt a long-range general plan every 10 years, and in Oro Valley the plan has to be ratified by voters. The 2016 plan was. The Town's own summary says the new plan creates no taxes and does not set the budget.
The Town Council voted 6-0 in May 2026 to refer the plan to the ballot. The plan on the ballot is the one the Council approved, with no later edits. The Explorer reports the digital document runs 137 pages, with 286 actions against 310 in the 2016 plan. Staff told the paper all of the 2016 plan's actions had been addressed.
Oro Valley voters have turned down a general plan before: one failed at the ballot in the early 2000s. Planning Manager Bayer Vella told the Explorer he attributes that defeat to too many residents feeling left out of writing it. This one was written with resident working groups the Explorer puts at almost 200 people, and more than 10,700 comments from surveys, booths, online discussions and meetings that began in 2023.
Heights, Housing and Where Growth Goes
The pamphlet's answer to "What does the plan say about growth?" is the most useful paragraph in it for anyone who owns or is shopping in town. With limited land left to develop, it says, the plan emphasizes targeted growth and redevelopment, and prioritizes limiting building heights, a variety of housing types with emphasis on opportunities for home ownership, conserving open space, and more retail, restaurants and gathering spaces. The development goal is to support diverse land uses that transition in scale and density from existing developments: new projects step down toward the neighborhoods already beside them.
Height gets specific treatment. According to ILoveOV's walkthrough of the plan, a guiding principle protects scenic views, policies prefer one- and two-story buildings, and the plan limits height for new apartment developments. It allows a case-by-case exception for a use the Town specifically wants, such as a major employer, which would likely go through public hearings. The working group agreed on that by majority, not unanimously. AZ Luminaria summarizes the housing goals as offering varied housing types while limiting high-density apartments.
The land-use map changes little. The Let Oro Valley Excel newsletter reported in May that staff said the plan's map mirrors the current General Plan map. It also picks up the Rooney Ranch and Town Center amendment the Council approved the same evening. Most of the plan is policy and a to-do list, not a redrawn map.
Water, Washes and the State Land North of Town
Water resources and conservation is one of the plan's ten topic areas, and AZ Luminaria lists diversifying water sources and limiting natural grass among its example goals. The plan's stated water goal is to increase responsible use of water resources for current and future benefit. On the environment side, it protects wildlife corridors and conservation areas.
Two large tracts are where that matters most. Arroyo Grande is about 9,600 acres of vacant State Trust land north of town toward the Pinal County line, whose land-use framework dates from a 2008 general plan amendment and includes a wildlife corridor between the Catalina and Tortolita mountains. Under state law, an open-space designation on that land stays provisional without the landowner's written consent, so the plan cannot lock it in by itself. Tangerine 880 is state-owned land with heritage saguaros and ironwoods, and the plan requires protecting those plants in new development, including annexations. The planning area reaches to Marana's boundary and takes in pockets of county and State Trust land, but ILoveOV notes that is not an annexation policy.
What OV's Path Forward Changes for Oro Valley Owners
Oro Valley has been an incorporated town since April 1974, covering about 35 square miles on the northwest side of the Tucson area. This site's Oro Valley page counts detached houses, townhouses and condominiums among its closings, built to a median year in the late 1990s. Its neighborhoods include master-planned communities such as Rancho Vistoso, and others with their own pages here, among them Cañada Hills and La Reserve. Addresses carry ZIP codes 85755, 85737, 85704 and 85742 and a Tucson mailing city.
A general plan does not rezone a lot, so nothing about an existing house changes when it takes effect. What it changes is the standard the Town applies to the next proposal. For an owner, that means a rezoning request next door is judged against a plan that prefers one- and two-story buildings, protects views, and requires new development to step down in scale toward existing homes. It also means a 10-year list of capital and code work. ILoveOV reports that more than half the actions are ongoing, such as pavement preservation, and the rest are re-ranked every two years in a Strategic Plan that feeds department budgets.
For a buyer, the plan says what kind of supply to expect: an emphasis on ownership housing and a mix of types, and limits on taller apartment buildings. It says little about the sheer amount of new housing, because the Town describes itself as having limited land left. Community gathering space carries over from the 2016 plan as one of its larger unfinished actions, now described as walkable, shaded and connected to The Loop.

Reading the Plan Before the Next Rezoning Hearing
The full plan is at OVPathForward.com, and printed copies are at Town Hall at 11000 N. La Cañada Drive, the Oro Valley Public Library at 1305 W. Naranja Drive, and the Community Center at 10555 N. La Cañada Drive. Questions go to 520-229-4836 or OVPathForward@orovalleyaz.gov. Official results come from the Pima County Recorder's Office, which ran the election. With the plan approved, it becomes the yardstick for every rezoning the Town hears for the next decade, replacing the 2016 plan once the canvass is official.
