The Ada County Commissioners are a three-member board that serves as the chief policy-making and administrative body for Idaho’s most populous county, setting the annual budget, deciding land-use matters, and overseeing county operations. The seats are currently held by Ryan Davidson in District 1, Rod Beck in District 2 (who serves as board chair), and Tom Dayley in District 3.1Ada County Idaho. Commissioners
Who Represents Each District
Idaho law divides every county into three commissioner districts of roughly equal population, and the sitting board redraws the lines before each general election to keep them balanced.2Idaho State Legislature. Idaho Code 31-704 – Commissioners’ Districts Each commissioner has to live in the district they represent, but every voter in Ada County gets a say in every seat. The elections are at-large, so a commissioner’s accountability runs to the entire county rather than one neighborhood.
What the Board Actually Does
The commissioners hold broad jurisdiction over county affairs within the bounds set by state law.3Idaho State Legislature. Idaho Code 31-801 – General Powers and Duties That authority sorts into three practical roles.
They run the executive side of county government. That means supervising department heads, managing county property such as the courthouse, jail, and parks, and coordinating with other elected officials like the sheriff and the clerk.
They legislate. The board adopts ordinances with the force of law on subjects ranging from animal control to emergency management.
And they decide land-use matters in a quasi-judicial role. When a property owner files for a zoning change or a subdivision, the commissioners hear evidence and testimony before approving or denying the application. For most residents, this is where they will encounter the board directly.
Setting the Budget and Property Taxes
The annual budget is one of the board’s weightiest tasks. Each June, elected officials and department heads bring their requests before the commissioners, who deliberate through the summer and formally adopt the budget in August, ahead of the fiscal year that starts October 1.4Ada County Idaho.

Property taxes fund a large share of that budget, but state law limits how much the property-tax portion can grow. The annual increase is capped at three percent above the highest of the prior three years’ property tax budgets, with an added allowance for new construction and annexation.5Idaho State Legislature. Idaho Code 63-802 – Limitations on Budget Requests and Property Tax Levies Voter-approved levies, bond payments, and refunds owed from tax appeals sit outside the cap.
One point of frequent confusion: Ada County is only one of several taxing districts on a resident’s property tax bill. Schools, the city, the Ada County Highway District, cemetery districts, and emergency medical services each levy separately, and the commissioners do not control those.4Ada County Idaho.

How Commissioners Are Elected
A candidate must be at least 21, a U.S. citizen, a resident of Ada County for at least one year, and a resident of their district for at least 90 days before the primary.6Idaho State Legislature. Idaho Code 34-617 – Election of County Commissioners The shorter district requirement reflects how recently redistricting can move the lines.
Elections are staggered so the whole board never turns over at once. At every biennial general election, two of the three seats are on the ballot: one commissioner is elected to a four-year term, another to a two-year term, with the four-year term rotating through districts one, two, and three in sequence.7Idaho State Legislature. Idaho Code 31-703 – Term of Office This is sometimes called the 2-4-2 cycle. The upshot is that every commissioner faces voters often, and at least one experienced member always carries over.
How Residents Can Participate
Idaho’s Open Meeting Law requires that board deliberations and official actions happen in public.8Idaho Office of the Attorney General. Idaho Open Meeting Law Manual Regular business meetings and public hearings are the main venues for residents to testify on proposed ordinances, budget adjustments, and land-use applications. Written testimony is accepted when you can’t appear in person.
The board must give at least five calendar days’ notice for a regular meeting and post the agenda at least 48 hours ahead. Special meetings require at least 24 hours’ notice. Agendas can be amended, but a change made less than 48 hours before a regular meeting has to be approved by vote at the meeting itself, and items added after a meeting begins cannot receive a final vote unless the board declares an emergency.9Idaho State Legislature. Idaho Code 74-204 – Notice of Meetings Agendas are posted at the county’s principal office and on its website or social media.
Removing a Commissioner
If a seat becomes vacant mid-term through resignation, death, or other cause, the remaining board members or the governor may appoint a replacement to serve until the next election, depending on the circumstances. The specifics vary, so the Ada County Clerk’s office is the right stop if a vacancy comes up.
Voters also have the option of recall. A recall petition must be signed by registered voters equal to 20 percent of the electors who were registered at the last general election in which the officer was chosen.10Idaho State Legislature. Idaho Code 34-1702 – Form of Petition, Filing, Fees Circulators have 75 days from the date of approval to gather the signatures. In a county the size of Ada, that threshold is a serious organizational undertaking, which is by design: recall is meant for genuine misconduct, not routine political disagreement.
