Unincorporated San Juan County, New Mexico has adopted: GOVERNANCE MODEL: San Juan County Building Division self-administers building, electrical, plumbing, and mechanical/HVAC permitting DIRECTLY for the unincorporated county (plus Aztec, Bloomfield, and Kirtland by service agreement) — it is NOT a New Mexico Construction Industries Division (CID) field-office pass-through jurisdiction for any trade. The County's own Building Department page states 'Construction Codes are adopted and amended by the State of New Mexico Construction Industries Division' (i.e., the SUBSTANTIVE code editions track the statewide CID-adopted codes), but the County itself issues, plan-reviews, fee-schedules, and inspects all four disciplines using its own application forms, its own fee schedule, and its own inspection staff reachable at (505) 334-4313 — there is no CID referral anywhere on the County's Building Department page, in contrast to jurisdictions in this corpus (e.g. Los Alamos County) that explicitly hand off electrical/plumbing/mechanical to CID.
