The Judges
New Mexico district and magistrate judges are initially appointed by the Governor to fill a vacancy, then stand in a partisan election at the next general election, and thereafter face non-partisan retention elections. They are state judicial officers, not county officials. The First Judicial District serves Rio Arriba, Santa Fe and Los Alamos counties; its judges page does not designate a chief judge. Magistrate judges usually set conditions of release at first appearance.

Notes on the record
- Capacity is marked yes on the published male/female bed figures in the Detention Center FAQs; no daily or average population is published.
- The Detention Center page refers to an 'Inmate Search' but no working roster URL was returned; roster is recorded no.
- The PREA page is a zero-tolerance policy statement with reporting instructions; no PREA audit report is published.
- The Finance Department page describes budget preparation but publishes no budget documents; the Commission Meetings page was empty and the Archived Agendas page carries agendas from 2015 to 2026 but not minutes. The county notes its website migration is incomplete and some links 404.
- The county states the facility holds prisoners for the US Marshals Service, tribal governments, Espanola Police Department and Probation and Parole, but publishes no contracts or per diem rates.

These three offices decide who sits in a cell in Rio Arriba County and what it costs the people who live here. Nationally, almost 77% of the people who died in local jails in 2019 had not been convicted of anything, and suicide was the leading single cause of those deaths (Bureau of Justice Statistics, Mortality in Local Jails, 2000–2019).
